On a typical PCB, the characters we see are usually painted in plain paint. However, some special circuit boards use copper as raw material for character marking.

A function of printing characters in copper is simply to look good. Use as nonferrous metal in product labeling can indirectly improve product image and brand value.

Another function of copper screen printing is to open the window in the stratum. As the foundation of electronic products, it links each component and keeps the current unobstructed. However, it is inevitable to generate heating in the working engineering. If the excessive heat cannot be spread out, it will not only hinder the current seriously, but also burn the circuit and cause damage. So the designers came up with an ingenious way of making the copper layer directly exposed to the air, which would allow it to dissipate heat more efficiently. So the designers combined the silk-layer characters on the surface of the printing plate to create a new process that combines thermal and expressive features - ground windowing.This technique is particularly common in high-power electronics。
