Cylindrical component bonding pad design - The shape of bonding pad is rectangle. When the reflow soldering process is applied, a concave groove must be designed

 

Care should be taken to distinguish between single ended and differential trace impedance. High speed single ended signals need to be routed with the specified single ended impedance.

The Drill file is generated by designers through the process of designing the printed circuit board with the Allegro, PADS, Protel 2.0 or Eagle software. How to export Drill file from software? We take the Eagle as an example.

 

General requirements for screen printing 

There are also problems such as electromagnetic compatible, vibration, and maintainability, test, and etc. What’s the relationship between the way of thinking and knowledge and our actual work? Let me explain to you one by one.
