DEFINITION

Soldering:Soldering is the metallurgical joining process of making a metallic bond between two metal surfaces to be joined with a filler material (called solder) which applied in liquid form establishes the joint when solidified.

11

Soldering And Assembling

LET’S Take an example:

To solder the leads of a resistor on PCB:

12

Step1.eg.ADD ANY COMPONENT (example shown is a resistor)by pushing the wires through the holes you have drilled in your PCB.

13

Bend over all of the wires that we’re not going to solder now.

14

CLEAN THE POINT OF THE IRON - take away any dirt on a damp

(not soaking wet) sponge when the iron is heated up.

This will help your solder to flow properly. 15

”TIN” THE IRON. This just means you should melt a tiny bit of solder

onto the point.

Try to avoid breathing in the fumes - they can be harmful.16

HEAT YOUR COPPER TRACK by holding the iron’s point on it for 3 seconds.

If you heat it for too long, the track will burn away.If you don’t heat it for long enough, the solder will not stick.17

TOUCH THE SOLDER WIRE ONTO THE TRACK and heat it quickly from above with the iron.

18

LIQUIFY JUST ENOUGH SOLDER TO MAKE THE JOIN and then pull the iron away.

Your join should look something like this one.You should only need a small amount of solder for each join.19

20

It is an alloy used as filter metal. Composition is 63%Sn &37%Pb Available in 3 types

Wire (flux mix) Rod Cake

Why Tin & Lead???????????

Tin is not affected by air or water. Tin reacts with metal easily Lead is soft dense, but surface gets quickly

corroded. Lead reduces the overall temp and adds the

strength.

21

Defects in soldering

Some of the common solder joint defects are :-

Cold jointFractured jointPitted or porous jointFlux/solder splattersContaminated jointPin holes/ blow holesOverheated jointImproperly bonded jointExcessive/ less solder jointRosin joint

22

A COLD JOINT

1. Once the convertors or any other instrument is ready with all components mounted and soldered properly ,there must be a through checking of the device which when performed with a positive result will let you mark O.K..

2. The checking procedures manually keep a closed look at what IC are doing. I.C. mounting and pin voltage are being checked.

23

TYPES OF TESTING Beat Test Line variation Test High voltage Test Heat Test It is calibrated in the required range with the help of

pots(variable resistors) zero(for minimum reading) and span(for maximum reading).

24

This software is new version of OCARD software. This is EDA- client 3.2 software for drafting of PCB circuit.

Most designs today are built on Printed Circuit Boards (PCBs), which consist of multiple layers of electrical copper and insulating material sandwiched together. Several Electronic Design Applications (EDA) exist to both create schematics of a circuit and transfer them to a working PCB layout. PROTEL is one of those software.

PCB DESIGNING USING PROTEL SOFTWARE With the introduction of relatively inexpensive, high-

quality PCB layout software for personal computers, it is now also common for prototype and one-off circuits to be implemented as PCBs.

Company has licenses for a schematic capture program Advanced Schematic and a companion PCB layout program Advanced PCB. Both programs were written by an Australian company, Protel Technologies Pvt. Ltd.

Project: Microcontroller Based Digital Indicator

Microcontroller based indicators are fully programmable Digital Indicators.

They are completely programmed from its front panel. Calibration as well as inputs can be given to the indicator with

the help of its 3 keys located on its front panel
