Roller Tinning Machine

Roller Tinning Salt is a highly active, water soluble, granular, acidic salt, specially formulated for roll tinning applications. The tinning of the PCB is accomplished by the transfer of solder from a metallic roller, that is partially immersed in a bath of solder, with a pressure roller ensuring contact of the circuit surface with tinned metallic roller. Tinning salt is added to the molten solder very slowly. This is a non-spattering formulation which gives a bright solder finish and full coverage in a single pass.
