What should we pay attention to in the process of high-frequency plate processing?

Impedance control requirements are relatively strict, and the relative line width control is very strict, generally about 2%.

Due to the special plate, the adhesion of PTH copper sinking is not high. Generally, it is necessary to use plasma treatment equipment to coarsene the through hole and surface to add the adhesion of PTH hole copper and solder ink.

Do not grind the plate before resistance welding, otherwise the adhesion will be very poor, and can only be coarsened with micro-etching potion.

plate is mostly with PTFE materials, with ordinary milling cutter molding will have many rough edges, need to use special milling cutter.

High frequency circuit board is a special circuit board with high electromagnetic frequency. Generally speaking, high frequency can be defined as frequency above 1GHz. It is often used in automobile anti-collision system, satellite system, radio system and other categories.
