What should we look for on PCB samples?

I am a purchase executive. And I have received the PCB samples from supplier. What do usually look for on the samples? What factors should I check?
  • PCB Assembly

Four basic factors you should consider during checking the PCB samples from the supplier.

  • Quality
  • Lead Time
  • Price
  • Sample Process. There are various processes to carry out PCB assembly. So,
  1. Pay attention to finding an original professional PCB manufacturer.
  2. Pay special attention to approving the process used by the manufacturer to ensure it can meet the requirements of your circuit board design and bulk manufacturing.
  3. After finishing,flying probe testing should be available.

What Others Are Asking

Is PCB testing of all nets after assembly required?

That is my first time asking an assembly house to produce 200 units of a PCB (and not the usual 3 or 5 PCBs). The assembly house came back to me saying that the testability of the board was bad and that they need to have 1.2 mm pads on the bottom side of the PBC for all nets… They require such large pads because beds of nails are a much more economical option than flying probe for 200-400 units since they can do it in-house. Is adding 1.2 mm pad on ALL nets common practice for PCB?

Can PCB’s contain spyware?

I’m thinking about purchasing a keyboard PCB from someone overseas, but I’m not 100% sure if it’s safe.
The firmware I’m going to install is QMK which is open source and I feel safe using it.
However, the PCB itself is making me a bit paranoid.
