Abstract:

The PCB layout of electronic products must take into consideration the manufacturability,the most basic requirement of which is the proper design of components board layout,the welding plate and the wire.This article summarizes the experience in actual production,discusses the design principles,requirements and methods of PCB layout,the welding plate and,the wire.Basic manufacturability of the design is the key to high efficiency,high quality and low cost production.The integration of manufacturability into the higher education teaching of PCB design is of great practical significance.

Key words: PCB;component layout;welding plate;printed wiring;design specifications
