FYS4260 – Spring 2018Microsystems and electronic packaging and interconnection technologies

Lab Project 1 - Introduction

Lab supervisors• Halvor Strøm• Erlend Bårdsen

• Stein Lyng Nielsen• David M. Bang

• Offices at ELAB, rom FV115• [email protected]

• Available all week, come by at elab, send us an email or give us a call if you need help.

Project objective

Create and build your own electronic circuitboard, from idea to an assembled, fully workingand tested PCB (Printed Circuit Board).

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.

DESIGN GOAL

SPECS

Lab work• At room FV204• 10 computers. • Organized as «workshops», where each week a

short tutorial will be given, explaining the next step in the design phase.

• One workshop on the lecture slot on thursdays. Depending on the number of students more times will be organized as needed.

• Show up on one of the workshops each week.• It’s mandatory to show your work once a week,

preferably in the lab!

Lab work• Access to FV204 outside normal workours (8-16)

only with activated access cards. If you need accesssend an email to the common course email with yourfull name, student card nr and UiO username.

• CadSTAR can be installed on any computer only in the UiO domain.

• It’s mandatory to show your work once a week, preferably in the lab!

Lab info• Everyone has to make their own schematics

and PCB, but you are welcome to collaboratewith each other on the same design.

• There is a big difference between workingtogheter and ending up with almost identicalPCBs, and just copying someone elsedesign.

• -> You will not learn anything, and I will seethe difference … ;)

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.

Time scedule 2018• 31/1 – Deadline for project choice• 7/2 – Deadline for Design Goal Specifications• 14/2 – Deadline for delivering final schematics• 21/3 – Deadline for delivering final pcb production

files• 24-26/4 – Assembly of boards at ELAB.

– Two groups, one day each– Starts at 0900!

• 5/5 – Deadline for delivering project report• 15/5 – Oral presentation

About the design

• Find a design you want to do!• Ideas at www.discovercircuits.com

or pick one of these:• Low Power ISM Tranceiver• Headphone Amplifier• FM Transmitter (Mobile to car FM stereo)

FM Transmitter

• Si4713 FM Transmitter

• ATMega48/328 8-bit Microcontroller

• Capacitive Touch Buttons

• 128 x 32 pixelsLCD

Low Power ISM Tranceiver

• ATXMega32 MCU• Si4455 ISM Radio at

868MHz• UART (serial) to PC

or Rasberry Pi• Temp and Humidity

sensors

Discrete OpAmp (Amplifier)

• OpAmp built withdiscrete components

• No Microcontroller• Dual Channel• ~2W max• Runs on batteries or

from 5V switcher

Custom Design?• Only components already in library

– Possible to ask for new components, but strict rules to what we might accept.

– Database at http://tid.uio.no/elab/FYS4260_html_Lib/index.htm

• No high power / high current designs. • No new microcontroller designs!

– Use FM or ISM design as a start, and addmodifications (without altering original functionality) ifyou want to build a «custom» microcontroller board.

• 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 useCadSTAR 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/LTspice)

Key points• Few components• Mechanical planning important, how do you

want to «interface» with your board, used in what environment (multiroom, car, inhouse)?– Capacitive buttons (with LEDs?)– Display– Antenna (internal/external)– Power source (eg wall transformer, car adapter,

battery, …)• Possible to extend with own functionality?

Low Power ISM Description

• Consist of a MCU which execute programmed logic, sensors, and an ISM radio transmitting and receivingdata packets to and from other low power ISM boards.

• A complete setup needs:– One concentrator board connected to a PC/RPi– One or more sensor boards.

• Only difference between the concentrator board and the sensor board are the code uploaded to the MCU, you shall only make on design!

PCB Antenna

Key Points• Measures humidity and temperature

– Three pins supported in firmware for customintructions.

• PCB Antenna needs to be very accuratelydesigned!

• Needs two boards to communicate => more work on assembly day.

• Depends on a PC/Rpi etc to have anymeaningfull function.

• Many pins available for own functionality.

Discrete OpAmp (Amplifier)

• OpAmp built withdiscrete components

• No Microcontroller• Dual Channel• ~2W max• Runs on batteries or

from 5V switcher
