1. Learning objectives

A student who has successfully completed this course will have

  • Designed 2 PCBAs from through the: schematic - layout - ordering and fabrication - assembly - testing phases.

  • Created new schematic symbols from component datasheets.

  • Created new PCB footprints from component datasheets.

  • Evaluated component selections for ease of assembly and availablity of alternate sources.

  • Soldered through-hole and surface mount parts.

Course Title for Transcript

“PCB Design”

4.2. Second page

Substance of Project

Students will learn the fundamentals of electronic circuit physical design through the schematic, printed circuit board, and assembly phases. Each will complete two projects of increasing complexity.

Method of Evaluation

Student work is evaluated on acceptable completion and documentation of each phase for each of the two projects on a four-level EMRN rubric.

4.3. Third page

Upload the following PDF of the syllabus:

5. Tools

  • KiCad for schematic and PCB layout.

6. Schematic basics

symbols light vs heavy symbols pins metadata multiple-part packages

pages inter-page connections

good style conventions idea: side-by-side good and bad examples good vs better

design rules ERC DRC other checks or policies use, setup why have enforced design rules?? "sign off" issues

netlists for simulation for pcb data

7. Printed Circuit Boards

7.1. Printed circuit structure

laminates

fabrication layers for photoresits

solder mask

silkscreen printing

surface finish ENIG HASL SMOBC plating

ROHS issues lead-free

7.2. Other

footprints create from scratch with datasheet from a quality library from vendor libraries built-in libraries ALWAYS cross check your libraries for accuracy, it will bite you eventually

design rules net classes current handling width spacing isolation creepage

physical clearance around hardware

package naming conventions and standards

??? IPC trainings to complete ???

through-hole typical package types DIP SIP TO-220 TO-92

surface mount package types SOIC SOT QFN BGA

floor planning strategies placement physical connectors working with an enclosure constraint mounting holes keep outs height of parts

violating design rules sign-off

8. Assembly

8.1. Soldering

  • find good tutorials for references

melting metal heat transfer is key clean tips flux

soldering iron hot air hot plate reflow oven

8.1.1. Practice boards

project: solder practice board (china thing) through-hole parts 1206 passives 0805 passives 0604 passives

SOT-23/etc transistors

TO-220 with tab SMT (name?). heat flow issues!

8.4. Solderless proto board

8.5. Point-to-point

lead

lead-free

8.6. Solder paste
