  Graphole

The Graphole Line is a process, which is used to place a small amount of graphite down the holes of panels, which need a connection between the top and bottom layers, i.e. Pth and Multilayer.

The panels pass through a cleaner then into a rinse before going into the graphite chamber. The panels are completely submerged in graphite and when they come out of the chamber the whole panel has a thin coating of graphite on it.

The panels then go through an oven to bake the solution onto the panel. As we only require the graphite down the holes for plating, it is no longer needed on the surface so the panels pass into a micro-etch chamber which removes the graphite from the surface. This restores the clean copper surface while leaving the graphite coating in the holes.

The whole process takes about seven minutes and the chemicals are constantly analysed to ensure the line runs correctly.
