Tin plating surface finish

2003

Dear Sir,

I am Mr. Mohan working in M/s Krone Communications Ltd. as a Asst. Mgr- Vendor Quality. I need following details. We do the Tin reel plating for connector contacts . During final stamping (after plating) we noticed lot of surface marks & scratch marks which is affecting visual aspects of the contacts. Could you please clarify the following points. a)Is there any surface treatment (Inorganic) to avoid visual marks during final stamping process? b) List of process parameter to be monitored in reel plating ?

Regards,

Tin is a very soft metal, so it is susceptible to damage. To prevent damage when stamping it, you could put an adhesive plastic film over the surface and remove it when you have stamped.
