We all know that there are many procedures for making HDI PCB from the planned feeding to the final step. One of the processes is called browning. Some people may ask what is the role of browning?

PCB (Printed Circuit Board) is an industry with a relatively low technical threshold. However, 5G communication has the characteristics of high frequency and high speed. Therefore, 5G PCB requires higher technology and the industry threshold is raised; at the same time, the output value is also pull......

For traces with a certain width, three main factors will affect the impedance of PCB traces. First of all, the EMI (electromagnetic interference) of the near field of the PCB trace is proportional to the height of the trace from the reference plane. The lower the height, the smaller the radiation. S......

Multi-layer PCB is a circuit board composed of more than two layers of electrical layer (copper foil layer) superimposed on each other. The copper layers are bonded together by layers of resin.

Nowadays, high frequency electronics are of great concern, especially in remote systems. With the rapid development of satellite communication, data items are developing towards fast and high frequency.
