PCB Electroless Copper: How Holes Become Conductive
PCB electroless copper creates the first continuous conductive layer on drilled hole walls before electrolytic copper plating. The process succeeds
PCB Desmear Process: How Clean Must Holes Be?
The PCB desmear process removes heat-smeared resin, drilling debris, and other contamination from drilled hole walls before metallization. A hole
PCB Resin Recession: When Is It Acceptable?
PCB Resin Recession occurs when resin withdraws from the plated hole barrel or surrounding glass structure, usually after thermal exposure.
