FYS4260 – Spring 2016 Microsystems and electronic packaging and interconnection technologies
Lab Project
1 - Introduction
Project objective
Create and build your own electronic board,
from idea to a fully working assembled PCB.
What is a PCB? • A printed circuit board (PCB) mechanically supports and
electrically connects electronic components using conductive
tracks.
• Components are soldered to pads on the surface of the PCB.
• Using vias to
connect the different
conductive layers.

Lab «Process Flow steps»
1. Find/decide on a design you want to do.
2. Make the schematics in CadSTAR.
3. Route the design in CadSTAR PR Editor.
4. Generate production files.
5. The PCB is produced externally.
6. Assemble the board at ELAB.
7. Test the board, do modifications.
8. Write a report.
9. Oral presentation.
Lab info
• Everyone has to make their own schematics
and PCB, but you are welcome to collaborate
with each other on the same design.
• There is a big difference between working
togheter and ending up with almost identical
PCBs, and just copying someone else
design.
• -> You will not learn anything, and I will see
the difference … ;)
Lab work
• At room FV204
• Approx 10 computers.
• We are available Tuesdays and Thursdays 9-
16, but the lab is open every day.
• CadSTAR can be installed on any computer
in the UiO domain.
• It’s mandatory to show your work once a
week, preferably in the lab!

About the design
• Find a design you want to do!
• Ideas at www.discovercircuits.com
or pick one of these:
• RF tranceiver (Weather Station)
• Discrete OpAmp (Amplifier)
• FM Transmitter (Iphone to car FM stereo)
FM Transmitter
• Si4713 FM
Transmitter
• ATMega48/328 8-
bit Microcontroller
• Capacitive Touch
Buttons
• 128 x 32 pixels
LCD
RF Tranceiver (Weather Station)
• nRF24L01+ 2,4GHz
Tranceiver
• ATMega48/328 8-bit
Microcontroller
• bq24074 LiPo
Battery Charger
• 128 x 32 pixels LCD
• Temp Sensor
Discrete OpAmp (Amplifier)
• OpAmp built with
discrete components
• No Microcontroller
• Dual Channel
• 2W
• Runs on batteries
MEMS MotionTracking (for reference,
only, not working, do not use)
• MPU6500 Gyro + Acc
• STM32F3 ARM controller
• USB battery charger
• Brushed DC Motor controllers (FETs)
• RC control interface
• Add a RC Transmitter and a battery and you
have a QuadCopter
Custom Design?
• Only components already in library
• No high power / high current designs.
• No new microcontroller designs!
• Each custom design needs to be
approved by us!
About the circuit layout (pcb)
• Starting size 5x7cm
• Use ELAB components
• Four layers
• SMD Components only on top side
• Use default FYS4260 settings
Project Tools
• For this course we are going to use
CadSTAR as our main tool.
– Design Editor to create the schematics
– PR Editor to place and route the design
– Mechanical models in Boardmodeller
– Circuit simulations in Pspice
