Dear Technetters As you know that prior to dry film coating or LPI soldermask coating, surface preparation is so crucial. it can directly effect dry film adhesion but we think that deburrinmg of the panels after CNC drilling operation and prior to electrolytic copper plating is more crucial. Does anybody have an application to deburr and polishing of the panels after CNC drilling. If yes which type of brushes you use for the first station to deburr and which type of brushes you use to polish the bord just after the deburring process.
