A MiniContac RS electrochemical plater is used to plate through-holes with copper between surface layers on electronic printed circuit boards. Additionally, a ProMask (solder mask) process and ProLegend (legend printing or silkscreening) are used to process the printed circuit boards. All equipment and chemical supplies are procured from LPKF Laser & Electronics.
