PCB Plating Thickness Printed circuit board plating is an electrochemical process in which a metal is deposited on the surface of a PCB, as well as inside of the plated through-holes. 4. Part of this bathing process coats the panel in a micron-thick layer of copper, which is deposited over the top-most layer and into the holes that have just been drilled. This surface can be modified in different ways by holes, slots or millings. That is, the outer part of the outer layer to be retained in the copper part, that is, part of the circuit on the part of the pre-plating layer of tin corrosion layer, and then chemically the remaining copper foil corrosion, known as etching. Initially all processes became suspect, from the bare printed circuit board (PCB), to assembly, the flux, the solder, the plating, etc. Browse the table below to learn more about our chemicals for printed circuit board fabrication including through-hole plating chemistry and other specialized applications.
