In the process of using the circuit board in peacetime, it is often caused by improper use, incorrect processing or aging of components, which causes the circuit board to work abnormally or even burn out. At this time, it is necessary to repair the circuit board. Next, I will introduce you to the pr

A printed circuit board (PCB) is an electronic component that connects different electronic components together. Designing a PCB is a complicated process that requires high precision. In the design process, some common errors will inevitably occur. These error problems are to help everyone avoid the

PCB design requires different grid settings at different stages. In the layout phase, large grid points can be used for device layout.For large devices such as ICs and non-positioning connectors, 50 to 100 mil grid precision can be used for layout. For passive small devices such as resistors, capaci

PCB copy board steps _ detailed full versionThe first step: preparationGet a good circuit board to see if there are components with high position. If you have the component number, component package, temperature value, etc., make detailed records. Scan as a backup before disassembling the component.

Printed wire width selection basis:The minimum width of the printed wire is related to the amount of current flowing through the wire:The line width is too small, the resistance of the printed wire is large, and the voltage drop on the line is large, which affects the performance of the circuit.If t
