PCB plays an extremely important role in electronic products, and it is the core part of electronic products. PCB has grown from single-layer to double-sided boards, multilayer b...

Generally speaking, the more complex the functions of electronic products, the longer the loop distance, the more contact pins, and the more layers the PCB needs. ...

In the PCB layout process, after completing the system planning, the PCB diagram should be checked to see whether the system planning is reasonable and whether the best results c...

I. Enhance the ability of PCB to resist deformation The deformation of the circuit board is usually comes from rapid thermal expansion and contraction caused by high-tempe...

For electronic equipment, a certain amount of heat is generated during operation, which causes the internal temperature of the equipment to rise rapidly. If the heat is not ...

Most people cannot tell the difference between a double-sided circuit board and a multilayer circuit board with the naked eye. If you do not carefully distinguish the appear...

Nowadays, electronic products are developing towards miniaturization, funtionalization, high performance and high reliability. The high-frequency board is high-frequency circuit ...
