Fixturing Overview 1

A fixture is a personalized mechanical interface between the princircuit board (PC board) to be tested and the test system.

In order to ensure the validity of the in-circuit inspection test, effective and reliable contact must be made to every electrical network on the printed circuit board. In enabling such contact, tfixture is perhaps the most crucial part of in-circuit testing.

It is necessary to define criteria that a successful fixture must min order to satisfy not only today's in-circuit test approaches butalso the types of PC boards being built and inspected.

This manual provides an overview of the Z1800-series in-circuittest fixture requirements. Many of the requirements apply to anfixture. For details on fixture requirements of the Z800-series or Z8000-series testers, refer to the system manuals and the Markand Mark 6 fixture kit manuals.

In-Circuit Fixturing CriteriaThe essential criteria to consider when developing in-circuit fixturing are

• reliability• ease of operation• interchangeability• maintainability• board design• ease of manufacturing• ease of modification• documentation• storage

Reliability

Reliability is a crucial requirement, because the success of the inspection test can be assured only if the tester makes unremittcontact with every electrical node on the board-under-test for thduration of the test. Because in-circuit inspection is typically usein a high volume production facility, highly reliable contact must bmade over thousands of cycles of use. The in-circuit tester is onlgood as the fixture it employs.

Ease of Operation

Placing the board-under-test on, and removing it from, the fixturshould be a simple operation. In fixture design, operator awarenease of placement, and possible sources of fatigue must be takinto account. These criteria become important in high volume production situations since the addition of even a few seconds tboard handling time can make a profound difference in overall tester throughput.

Interchangeability

Test system flexibility depends on the ease in which fixtures caninterchanged. The following considerations should be taken intoaccount. First, changing fixtures should require a minimal amouof time—approximately 30 to 60 seconds to remove one fixture ainsert another. Second, this action should require minimal mechanical skill. Third, the fixture should be light weight as it caeasily and safely be handled by one person.

Maintainability

Fixtures require periodic maintenance since board debris and flreduce contact efficiency, and contact pins may break. Servicinease determines the length of test production downtime for a particular board type. When designing the fixture, you must consider the ease in which the fixture can be disassembled andreassembled. Simplicity reduces turnaround time and eliminatesneed to build duplicate fixtures.

Board Design Considerations

When you design the fixture, you need to know the nature of thboard it is meant to work with.

• Is the board clean?• Are test pads located for easy contact?• What is the density of the components?

Dirty boards without neatly shaved leads or even solder pads ncontact pins with sufficient compression depth to account for uneven component attachment points, sufficient lateral strengthprevent those leads from bending the pin, and enough force to penetrate nonconductive material on the solder.

Manufacturers are achieving unprecedented component densitirequiring increasingly denser contact pin locations in the fixtureTherefore, the pin and its associated guiding and socketing mussmall enough to accommodate pin spacings down to 0.040 inchcenter or less. Test pads must also be conveniently located for contact.

Ease of Manufacture

Manufacturing simplicity influences the cost of the fixture—whether commercially supplied or built by the user. The less labintensive the fixture, the more economical it is. A primary consideration is the minimization of special tooling (such as higspeed drills) required to build the fixture. The end user, who buithe fixture using only tools found in a model shop, reduces the tand expense required to bring the fixture on-line.

To decrease manufacturing costs and improve quality, supplierscompleted test fixtures are turning to automated design approacComputer programs which interpret computer-aided design (CAfiles can locate and identify nodes more accurately and quickly tmanual approaches which use bare PC boards and mylar artwo

Ease of Modification

The only certainty about any PC board layout is that it will changOften, an engineering change order (ECO) or artwork change requires relocation of one or more of the contact pins in the "beof-nails" fixture. It is more economical to modify a fixture except rare cases where the artwork changes so much that it requires abandoning the present fixture. As with maintenance, the ease which pin relocation is accomplished often determines the overeconomy of the fixture. Ideally, pin relocation should take no longthan 15 minutes per pin and should not require any special toolother than those commonly found in an electronics assembly ar

Documentation

Fixture documentation should follow strict document change procedures which stress up-to-date information.

The documentation should describe in detail

• the exact location of every node• the type of contact pin required• power wiring• any special wiring requirements for relays or special circuits

mounted in the fixture• all fixturing modifications

Storage

As in-circuit inspection systems increase in usage and number,more and more PC boards must be fixtured. Consequently, the number of fixtures has grown considerably.

A fixture design must address ease of storage and minimum storequirements.


Fixturing Approaches

Fixturing ApproachesThe two basic fixture types are vacuum and mechanical.

Vacuum FixturesThis section describes a typical vacuum fixture, its advantages disadvantages, and the options available.

Figure 1.0 Bed-of-Nails Fixture

The vacuum fixture uses an internal spring-loaded contact pin socket mounted in a fixed base platen. When the vacuum chamis actuated, the board-under-test travels downward, making conwith the individual spring-loaded contacts.

Variations of this design have been in use for many years. This probably the most familiar fixture design. Its popularity arises froseveral tangible advantages, which are described below.

For this design, the contact pins strike the bottom of the PC boawith high velocity. The pins penetrate the solder pads more deeoffering a more reliable pin contact than a typical mechanical fixture.

High Registration AccuracyThe contact pins in the vacuum design are mounted in a fixed platen. Linear bearings may be used to guide the top plate. Thisapproach can be reliably adapted to pad sizes down to 0.035 inand 0.040 inch pad spacing. Smaller pad sizes can be adaptedspecial tooling and/or contact pin design.

Simple MaintenanceThe design allows rapid access to the significant operating portiof the fixture. Since contact pins are typically socket-mounted, ycan remove and replace them in a few seconds.

Ease of ModificationModifying a fixture to add additional probes requires precision drilling of only one platen. Contact pins are socket-mounted, providing a large variety of probe heads that can be used for different situations.

Disadvantages

The disadvantages of vacuum fixtures are

• cost• maintenance

The vacuum seal and number of mechanical parts result in a typically more expensive fixture than an equivalent mechanical fixture.

The vacuum seal wears with use and must occasionally be replaAlso, the vacuum may draw debris into the fixture which contaminates the pins. Diligent cleaning of the fixture is require

Available Options

Fixture kits are usually sold for a specific series of testers. Z800 Z1800-series interfaces are available in 320, 640, 1024, and 12pin configurations. These interfaces may be combined to provideto 5120 pins.

The following vacuum fixture options are available

• single well• multiwell• dual well or tandem• mechanical hold-downs• top access• zero-flex• bilevel• antistatic platen

The options are described below.

Single WellThe single well fixture is perhaps the most common fixturing option. One board type is adapted to a single vacuum well fixtuFixtures are available to adapt to many board sizes. Most fixturemanufacturers offer small, medium, large, and extra large headstyles to accommodate various board sizes. In general, the largfixtures can accommodate boards up to 16" x 20".

MultiwellThe multiwell fixture is the same as single well fixture, but multipboards may be fixtured in the same vacuum well. Usually, this method saves fixture cost when you have several small boardsCover plates, which are made of acrylic, fill the board access howhen boards are not being tested.

Dual Well or TandemTwo separate vacuum wells are contained in one fixture frame. second vacuum port controls the well on the left side. Dual well atandem fixtures are very efficient for high volume applications. While you are testing a board on one side, you can unload and reload a new board on the other side. Dual well or tandem fixtuminimize board handling time and can increase system through

Mechanical Hold-DownsAlso called overclamps, mechanical hold-downs are hinged covwith push down rods that clamp the board to the top plate.

Overclamps are required for boards that have many open vias odesigns in which adequate vacuum sealing is difficult. Overclamcan also be used for thin boards and multi-panel boards which to warp and cannot achieve a good initial vacuum seal without assistance.

Some applications require the vacuum chamber to be located outside of the board area. Boards which have too many openinand which cannot be sealed with vacuum gaskets require an external vacuum chamber. Also, some customers with dirty or nclean flux environments, elect this method. Since the vacuum isoutside of the board area, the fixture pins stay cleaner and lessis inducted into the vacuum system.

Top AccessSome boards require access to the test pads on top of the boarSeveral options are available to achieve access. Transfer pins, which are mounted in the fixture, transfer signals to pins mountin a top access unit. This unit is usually mounted with a mechanoverclamp.

Zero-FlexThe typical method to achieve clearance of the components onbottom of the board is to put small standoffs on the top of the fixture to support the board. This method is adequate for most applications. The zero-flex option is good for large SMT boardssince they may be damaged due to flexing during test. The top pis routed out so that the board is flat and fully supported on the surface of the fixture.

BilevelTo accomplish performance functional testing on the same fixturemoving contact to the ICT pins may be required. Bilevel optioare available that are either vacuum or air pressure actuated. Sockets and probes of different lengths are used in this configuration.

Antistatic PlatenAn antistatic platen is an effective option to reduce potential stadamage to the board-under-test. The top plate is coated with a sdissipative material and is grounded to the system.

Mechanical FixturesAll mechanical interfaces are similar, with a single bottom platenfor mounting internal spring-loaded contact pins and a top pushplate to force the board down onto the pins. This is usually accomplished by "legs" mounted on the top plate. The top pushplate can also be equipped with contact pins to contact test padtop of the board. Transfer pins are usually added to make electrconnection to the top plate pins.

Advantages

The advantages of a mechanical fixture are

• low cost and ease of manufacture• no vacuum requirement• suitability for low volume applications• automated handling capability

Mechanical fixtures are frequently sold in low cost kit form. Simpones can be as much as 30 percent less expensive than an equvacuum fixture. No vacuum sealing is required and board guidinusually simple. Typically, special tooling is not required to manufacture mechanical fixtures.

Mechanical fixtures do not require vacuum; however, many desirequire air-pressure to operate the push-down mechanism.

Because of their low cost and elimination of vacuum requiremenmechanical fixtures are frequently used in low volume, high mixproduction situations. Kits may be assembled quickly and fixturmodification is accomplished with simple tools.

Mechanical fixtures can be adapted for automated handling systems.

Disadvantages

The disadvantages to the mechanical fixture approach are

• handling time• accessibility

Use of a manual mechanical fixture is a two-step operation, increasing absolute board handling time. First the board must bplaced on the guiding pins for proper alignment. Second, the fixtusually must be actuated manually. Releasing the board from thfixture involves the same two steps in reverse order. Typically, loading and unloading times are 50-100 percent longer for mechanical fixtures than for their vacuum counterparts.

Mechanical actuation pressure must be applied to the board-untest to assure reliable contact to the pressure pins. "Legs" are mounted on the top plate to apply pressure. Access to the boarsometimes required for program development or during actual testing, and electrical contact to the board via a probe is not possible while the fixture is engaged.

Available Options

Mechanical fixturing options are available from third party vendoEach mechanical fixturing option generally has its own unique fixture design.

The options available with mechanical fixtures are

• single well• top access• zero-flex• automated board handling

Single WellThe single well fixture is perhaps the most common fixturing option. One board type is adapted to a single well fixture. Fixturare available to adapt to many board sizes. Some custom installations have included two separate push-down units to achdual well like operation.

Top AccessAll of these fixtures are easily adaptable to top access pins withaddition of an intermediate pusher plate to mount the pins.

Zero-FlexThe top pusher plate and bottom platen are routed out so that tboard is flat and fully supported on the fixture.

Automated Board HandlingSeveral automated board handling systems are available from tparty vendors. Each handling system requires a unique fixture design.

The requirements for each method are described below.

Method 1—Full CAD Data

CAD files can be processed with a fixture design package to provide a padmaster drilling file, a pin location file, a board outlifile for vacuum seal design, and a pin wire list. Also an input listcan be developed for program generation. The loaded board is required to select probe types, test the vacuum sealing, and vethe clearance between the board and bottom platen and optionthe top plate or overclamp.

The minimum requirements are

• CAD files—Net name, X-Y coordinate, device and pin numberrelationship is the minimum required information. An ASCII format computer file is the preferred media.

• parts list—An ASCII format computer file is the preferred mediespecially to develop an input list.

• board power requirements• schematic (some fixture design packages have the capability

plot noded schematics from CAD data)• loaded board

Optionally you may be asked to provide

• assembly drawing• bare board• board rework instructions if applicable

If you design your own fixture with a design package, the fixturevendor will require only fixture design files and a loaded board tselect probe types, test the vacuum sealing and verify the clearbetween the board and bottom platen and optionally the top platoverclamp.

Method 2—Partial CAD Data

Providing only Gerber format design files with a loaded board, apaper schematics and parts lists is more costly than method 1. Gerber files can be processed to provide a padmaster drilling fipin location file, and a board outline file for vacuum seal designThe wire list and input list cannot be automatically generated. Tschematic and parts lists are required to manually input this datAn aperture list and drill file may also be required to verify pad

Method 3—No CAD Data

Bare boards and/or a 1:1 mylar copy of the artwork can be usedconjunction with paper documentation to develop padmaster drfiles and board outline files. This method may not be accurate opossible with some SMT designs and will be the most expensivSince the pin locations are generated from a bare board or mylacopy with a bombsight type of visual drilling process, pin locatioaccuracy is generally limited to .040 inch spacing. Pin locations wire lists must be developed manually or wiring can be random later probed to develop an input list.

Fixture Design GuidelinesFixture building is a precise procedure which requires drilling, probe locating, node mapping, node wiring, and power distributiConsider the following factors before you build or order a fixture

• fixture size requirement• drilling• probe location• probe selection• troubleshooting the completed fixture

Fixture Size Requirement

You must select a fixture size which is large enough to accommodate the board you plan to test both in node count as as physical size. Most fixtures will accommodate slightly larger boards than the maximum pin field size. The pin field is the areaa fixture where pins may be located.

Drilling

To facilitate Engineering Change Order (ECO) implementation, Teradyne recommends drilling a hole for every component lead test pad. This drill pattern is called the padmaster. You will use some of these holes for probes. The extra holes are useful whenan engineering change requires that you add or move probes.

Avoid drilling at feedthrough holes which are often closer than 0.040 inch minimum recommended spacing. Drilling at such clodistances will significantly weaken the fixture platen and may cahole break-out.

To prevent vacuum leaks in the padmaster-drilled fixture, seal aunused holes with an adhesive-backed film before installing theprobe sockets.

Probe Location

The process of determining probe locations is unique to each Pboard. To evaluate potential probe locations, you should considthe following location guidelines:

• output nodes in digital areas• sealing• low impedance analog• power supply probes• density

Output Nodes in Digital AreasMinimize backdrive signal degradation by locating signal probesclose as possible to the backdriven component's outputs.

SealingAvoid vacuum leakage by placing probes on the PC board interrather than at the outer edges whenever possible.

Low Impedance (< 200 ohms) Analog MeasurementAdd sense probes on the same net for 6-wire measurements.

Power Supply ProbesFixture spring probes are typically rated to carry 1-3 amps maximum per probe. Probes operating above their rating have shorter service lives. The Z1800-series testers are capable of delivering up to 45 amps. To select an adequate number of powprobes, follow guidelines in the Fixture Wiring section of this manual.

DensityAvoid placing large numbers of probes in a small area since prodensity can affect the flatness of the board during test. If the dearea is near the edge of the PC board, vacuum leaks may occu

Probe Selection

The most common probe sizes are 100 mil, 75 mil, and 50 mil. Probes are also available in 40 mil and smaller diameters. The smaller sizes are required to access very dense circuit areas. Tsmaller probes which are more costly and less reliable have lesspring force and therefore more difficulty piercing contaminationon a board.

Choose the largest probe size that will work for your applicationThere are also various probe head styles and probes for speciaapplications.

Most probes also are available with various spring pressures. Scommon probe styles and their uses are shown below. For furthinformation contact a reputable probe manufacturer.

Figure 1.2 Probe Point Styles

Serrated or 9-Point StyleThe serrated probe, because of its large contact area, is the mocommonly used probe style. It is used on most component leadtest pads, and edge connectors. Because of its size and shapeserrated probe may get contaminated more easily than other tyof head.

Pointed StyleThe pointed probe style provides excellent penetration. It is usewhen leads are covered with solder or when boards are coverewith protective coatings.

Cupped or Concave StyleThis inverse conical style is used on long component leads, wirwrap posts, and clean surfaces.

Troubleshooting the Completed Fixture

Leaks

If the fixture leaks air when vacuum is applied during test and debug, apply the hole-plugging methods described below to seaholes in a board.

• Add a bumpon or rubber pad to the fixture top plate under a leing hole.

• If the seal is leaking at the edge of the board, add poron stripssprings underneath the top plate to provide extra perimeter support. The procedure should be performed only by an experienced fixture assembler.

• Lay a sheet of antistatic plastic over the board before applyingvacuum.

No-Contact (Opens)

"Opens" or no-contacts occur when the electrical resistance pabetween the component and the tester has become so great thtester cannot detect the presence of the component. You should

• Check each component lead to ensure that it is not too long athat it uses the "best" probe head style for its application. Ofteprobe can glance off of a component lead if the lead and probhead style are not matched properly.

• Check that the fixture achieves 2/3 probe travel when the PC board is pulled down. If the probes are pushed down more tha2/3 of the way, you must reduce the socket height.

• Check for stuck probes. If the probe is stuck in the down positireplace it.

• Check the system receiver pin and verify that it is not stuck.• Check for foreign material which may be covering the probe

interface, and the wire to verify that everything is connected.• Check the driver/receiver card for the point which has a

no-contact. The diagnostic check for the tester catches most problems, but problems do occasionally develop between diagnostic checks.

• Check the fixture for signs of physical damage. Verify that thefixture looks normal. If you suspect that the fixture is damagedverify that the fixture interface is seated properly in the tester receiver and check that bent probes are not present.

• Check the board for signs of physical damage. If you suspect the board is damaged, check for excess solder at the bottom oboard, and check for scraped off solder.

• Check the board revision. You may have an older revision of tboard. Even if the board fits on the tooling pins, the probes mnot be in the appropriate places to make proper contact.

• Check the vendor’s work if you have changed PC board manufacturers recently. He may have a different board manufacturing process than the previous manufacturer. The tooling holes may be slightly off, therefore causing misregistration, or solder may have been left off feedthroughscausing a vacuum leak.

• Check that the board tooling pin holes are in the correct locatioTooling pin holes must be in their exact intended locations, otherwise, misregistration occurs. Also, verify that the fixture

Fixture Maintenance GuidelinesPC boards may accumulate debris and flux, which can reduce fixture contact efficiency. Keep your fixture in top condition with regular inspection—a minimum of once a day and more often wthe production environment dictates. Take time to take care of yfixture. With proper care and maintenance, it will last as long asPC board remains in production.

Maintenance Hints

These following maintenance hints will help prolong fixture effectiveness and ensure consistently accurate test results:

• Run the fixture self-test prior to each use.• Inspect the fixture daily.• Inspect the fixture first, when you notice a change in the test

system's performance.• Do not leave tools inside the fixture.• Keep the fixture's surface free of dust and contaminants by us

a soft brush and compressed air. Clean with 100% alcohol.

Note: Use eye protection when using compressed air.

• Look for sticking, bent, or broken probes using the clear plate• Check for bumpers that may shift and interfere with probes.• Replace dirty or contaminated probes. It is best to replace pro

as needed, however in some cases spring probe conductivity be improved if the spring tip is cleaned of all contaminants. Seprobe cleaning tips below.

• Handle the fixture carefully. Probe pins can be easily damage• Store fixtures in a clean environment to prevent dust build-up.• Do not stack fixtures on top of one another.• When modifying a fixture, do not rest the fixture on its top

surface. Damage to the tooling pins or probe pins may result.• When the fixture bottom cover is removed, do not place the

fixture on its bottom surface or the sockets may be damaged.

Do not use acetone, chlorinated hydrocarbons,ketones, lacquer thinner, or MEK. It will destroythe seal.

Do not attempt to clean the probes when they are installed in the fixture. This will damage the fixture materials and the clear seal.

• The clear film on the underside of the platen provides an airtigseal. If it is accidentally punctured, loosened, or a socket is removed, there will be air leaks that can affect the fixture vacuuSmall leaks can be patched using a silicone sealant.

• Keep a fixture log to document that maintenance is performeddaily and at other scheduled intervals.

Removing a Broken Probe

You can remove broken probes from the fixture and/or fixture receiver in one of two ways documented below. In both cases, remove whatever portion of the probe sticks out above the sockfirst.

Method 1Carefully insert a small round jeweler’s file in the barrel of the probe by pushing or turning gently until you can get enough gripthe barrel of the probe to pull it out. Be careful not to damage tsocket or push the socket out of the platen.

Method 2Carefully screw a small (#60 (0.040) for 100 mil probes) drill bitwith a diameter just slightly larger than the inside diameter of thprobe into the barrel of the probe turning gently until you can gegrip on the barrel of the probe. Then, pull the probe straight up out. Be careful not to damage the socket or push the socket outhe platen. Do not attempt to drill out the probe unless you are prepared to remove the receiver and replace the socket that theprobe was in and possibly the node I/O card underneath it as w

Probe Cleaning

As a general rule, spring probe cleaning is not recommended.

Do not submerge probes in Freon TF or other cleaning agents oultrasonic cleaning. Submerging probes and ultrasound cleaninremove essential lubricants from the probe and rapidly wear dothe probes. Poor performance occurs because the insulating particles move into the area between the plunger and barrel portof the probe.

To clean probes, remove them from the fixture and carefully usesoft nylon brush and an approved cleaning solvent to clean the probe heads only. Do not allow solvent to drip down into the proThoroughly dry the pins, before you reinstall them in the fixture.
