Tin Plating Copper PC Boards

PCB tinning is the process of depositing a very thin layer of tin, for the purpose of protecting the copper from oxidation. Oxidation on copper makes it more difficult to solder. Keep in mind, though,...

Etching your own Prototype PC Boards

PCB Etching is as simple as immersing it in the etchant solution and agitating it to keep sludge from inhibiting further etching. This can be done in plastic or glass trays, vertical etching tanks, or...
