PCB Check List
JohnsonMiller , 09-12-2017, 08:11 AM
Hi Guys,
After many years in PCB design, releasing a new PCB still I have stress "Did I missed a point?"
I have seen many PCBs failed since missed to check all issue, sometimes very simple ones! I use schematic compile, check all messages and treating warning as error, and also using DRC on PCB, it reduced the fail rate. However there are some case that even ERC/DRC is unable to detect, ex: connect a bypass CAP to a power pin but forgot to connect it to power supply, there will be no ERC and also no DRC, but board fails. Another example, when I forgot to add teardrop, PCB is working but quality is not good and reliability is reduced.
So that I am looking for a PCB check list, do you know any?
Probably we can do a brainstorming to setup one for the forum users,

Hey @JohnsonMiller don't exactly getting your point.. As you connect capacitor in schematic it will automatically import all the connections in PCB file..

Hi @JohnsonMiller,
some time ago I created a PDF with points to check a Schematic:
https://www.fedevel.com/welldoneblog...ing-procedure/
I was planning to create similar PDF for PCB, but I have never collected all the points
Only what we have is Release procedure, which covers some basic steps (e.g. do not forget run DRC before you generate manufacturing documents). The release procedure can be found in our FEDEVEL Directory structure, under Released Files: https://www.fedevel.com/welldoneblog...tory-template/
I hope at least this can help a little
