What are the possible reasons that a PCB doesn’t work?

Mistakes in making of schematics: Miss out net names off-page connectors and interconnection is one of the most frequent mistakes. You should check them carefully. Bovendien, if there is a wrong wire connecting and bad wire crossing over each other, your schematics still be malfunctional.

Shorting in PCB tracks, sporen, pads, and obstacles: Eigenlijk, there should be no shorting between power and ground check, Vervolgens, you are required to check any stick to proper clearance and track spacing.

Power to the Components: Ensure the right polarity connection and ready IC socket connection.

Proceed with PCB Assembly section by section
No conduction via through hole: Often there is no conduction via through-hole if the plated through home is not proper. In zo'n geval, it is advisable to solder the IC pin on both layers.
