Requirements for machine clamping edge (process edge) Process edge: PCB edge that will be clamped when placed on the conveyor rail of the machine. The width of the plywood is 5mm (3mm on the front); The clamping edge is required to be parallel and straight, and no component can be placed 5 mm (3 mm on the front) close to the plate edge (if not, please add the process edge);

Integrated circuits (IC), also known as microelectronic circuits, microchips,s or chips, are electronic component components, manufactured as a single unit, with miniaturized active devices (e. g., transistors and diodes) and passive devices (e. g., capacitors and resistors) and their interconnections built on thin substrates of semiconductor materials (usually silicon). Thus, the resulting circuit is a small, monolithic "chip" that can be as small as a few square centimeters or only a few square millimeters. The dimensions of individual circuit elements are usually microscopic.

There are many professional explanations about PCBA on the Internet, which is difficult to understand. Today, I will explain PCBA to you in the most popular language.

The layout of components not only affects the aesthetics of the PCB but also affects the performance of the circuit. The following points should be noted:
