When removing solidified tin, substrate becomes exposed

November 4, 2016

Q. Dear sir,

We are basically manufacturing the heat pipe system.

For assembly of heat pipe, we are using the Aluminium block with electroless nickel plating and copper tubes with tin coating; after inflation tin is overflowing the tubes.
Please suggest how to clean the over flowing tin (solid).
While cleaning, base metal is appearing -- but our customer requirement is should not appear.

A. Hi Anand. I don't see how any cleaning solution is supposed to know which lumps of hardened tin you want it to remove and which tin you want it to leave in place undisturbed.

I think the answer is flowing the tin differently, or shaking or vibrating the excess off before it solidifies, or switching from hot dip tin to electroplated tin. Good luck.

Regards,
