- 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. そのうえ, if there is a wrong wire connecting and bad wire crossing over each other, your schematics still be malfunctional.
- Shorting in PCB tracks, トレース, パッド, and obstacles: 基本的に, there should be no shorting between power and ground check, その後, 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. このような場合には, it is advisable to solder the IC pin on both layers.
