The use of immersion gold PCB mainly has the following characteristics.
Users requirements for large-size backboard that can work at high bandwidth leads to the need to exceed the processing capacity of conventional PCB manufacturing lines
A brief history of PCB board development
PCB circuit open, short circuit is the PCB manufacturers almost every day will encounter problem, has been plagued by production, quality management personnel.
For any company that wants to create own brand product series, PCB prototype design is essential. For the PCB company that designs new PCB for customers, its also an important process. PCB prototype design is very important, because it is a process that a

The two major difficulties in the field of microelectronics are high-frequency signal and weak signal processing, in this respect PCB production level is particularly important.
Detailed analysis of high frequency PCB parameters
In circuits with resistors, inductors and capacitors, the obstruction to alternating current is called PCB impedance.
