摘要
In an appts. for thick tinning of Cu, Sn, Bronze or Ni lead wires of circuits and components, the wire is passes in turn through an acid etch bath, a tin(alloy)bath, with a first guide pulley, a wave shaped nozzle to wipe off surplus metal, and a cooling region with a broad guide pulley. The guide roll in the tin (alloy)bath has a protective coating of silicon nitride. It is further provided with stainless steel reinforcement. Thermal shock resistance is good at 20-350 degrees C (dipping pulley into the tin bath). The surface is not wetted by molten tin (alloy), the material has good mechanical strength, even under impact loading, exhibits low friction at 20-350 degrees C when immersed and when in air, low wear, low thermal expansion.
