Pcb Design Checklist

Basic Check List 1. Print out out scale scale drawing drawing of your board board and place place actual componen components ts on it to verify verify footprints. See directions on how to do so: 1. Printing PCB to Scale 2. Does the the board have the the correct correct Advance circui circuits ts specificat specifications ions in Altium Altium 1. Advanced Circuits Specifications 3. Name Name and Revisi Revision on numbe numberr on on board board.. 4. Put the the board dimensi dimensions ons on the the top overlay, overlay, outis outisde de a board board outline outline for the the manufacturer to see. Check if the Board Dimensions appear on the Gerber Files and are accurate. 1. You can put put extra extra comments comments in the the Overlay Overlay outside outside the the board so so the manufacturer can utilize them and they won't show up on your final design. 5. Check plane clearances clearances to avoid avoid shorts shorts when solder soldering. ing. 1. See the Adding Custom rules – Polygon Pour Clearance Section of  Altium_PCB_Layout_Tutorial.pdf to Altium_PCB_Layout_Tutorial.pdf  to create a clearance rule. 6. Verify Verify transmit transmit and and receive receive pins are are correct correct for serial serial ports. ports. 7. Verify Verify silkscr silkscreen een labels labels are are not under component. component. 8. Verify Verify traces traces are are large large enough to handle handle the the load current. current.

Passed Passed the Design Rule Check Check (DRC) (DRC) withou withoutt any criti critical cal errors errors 10. Did I add in my ground plane before generating the the gerbers? 11. Bypass capacitors are are placed very close to their corresponding corresponding components. 12. Mounting Holes (for stand-offs) stand-offs) 140-150 diameter Mils Mils of hole size is pretty standard. 13. All testpoints/headers testpoints/headers are labeled with with usable silkscreen silkscreen designators 14. All components have orientation designators designators (location of pin 1 with with a number or a dot) 15. All components have part designators (U1, R12, C4 etc.) etc.) 16. All polarized components have a (+) or (-) silkscreen designators 17. Important component Information Information is labeled labeled with silkscreen silkscreen designators 18. Large/Oddly shaped components have profile in Silkscreen and they do not interfere with other components. 19. Labels not covered by parts or no silkscreen overlap 20. Power LED LED for every voltage voltage rail 21. Programmer header connection. Have I doubled checked the wiring for the connector? 1. Programmin Programming g header(s) header(s) oriented oriented in in the correct correct directi direction on 22. Potential Potential De-Bug De-Bug LEDs LEDs 23. Add power disconnect jumpers if you want to be able to disable disable part of your   board during testing. 1. Or add a Power disconnec disconnectt for each each chip (2-pin (2-pin header) header) for independe independent nt testing if needed 24. Extra Headers/Testpoints/Vias Headers/Testpoints/Vias for testing testing various signals signals

25. Multiply extra testpoints/headers for power and ground (oscilloscope gnd connector) 1. Or for connecting power off of the board 26. Trace sizes power requirements are met (Advanced spec: 1 oz cu plate) 1. link to trace-Current capacity page: http://basicelectronic.blogspot.com/2006/09/track-width-referencetable.html 27. Ground connections between different board/systems where data is transferring 28. Separate Digital and Analog ground (if necessary) for noisy, inductive components 1. If using motors or other inductive loading, separate voltages/gnds for  digital and analog rails. 29. Voltage Level shifters present for data transmission between boards or chips with different voltage supply values 30. Have I ordered parts yet? Are all the parts I put on the PCB instock and ordered already. If not, get them first, then order the board. Or redesign with different components. 31. If you are not sure about certain digital connectors (TX/RX) have I added in disconnect headers for adding jumpers?
