Assemblée PCB

Quelles sont les raisons possibles pour lesquelles un PCB ne fonctionne pas?

  • 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. Quoi de plus, if there is a wrong wire connecting and bad wire crossing over each other, your schematics still be malfunctional.
  • Shorting in PCB tracks, traces, coussinets, and obstacles: Fondamentalement, there should be no shorting between power and ground check, ensuite, 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. Dans ce cas, it is advisable to solder the IC pin on both layers.
