The bare circuit board may be assembled on different levels. A cheaper level of the board may have some missing parts that go into a final product at a cheap level. Some boards with special features tend to face the same problems, te. Label part numbers to help identify this problem.
By the way, the assembled board might have a stick-on label with the final assembly number.

There is a copper pour over the entire top of the my PCB, which is part of GND net. It turns out that the surface mounted 1W LEDs I’m going to use have the heat slug connected internally to the LED’s +ve terminal. Can I rely on the solder mask to insulate the +ve voltage (~3V ish) from GND? Long term?
I ordered RF PCB design and prototype from my supplier . There are something like a hole, but it is not, on the ground surface. What is the purpose of making these holes? The PCB is inside of the E70 433NW14S LoRa module.
Wij zijn een bedrijf in huishoudelijke apparaten en zijn nu van plan een magnetron te ontwikkelen. PCB is het belangrijkste onderdeel van het apparaat en we weten dat het geen eendensoep is. Wat zijn de verschillen tussen magnetron-PCB's en gewone PCB's??
