Subject: Re: wave soldering machines - would they tin a board?

From: "Bob_xyz" <bob_barr@...>

Solder paste consists solder, in the form of tiny spheres, suspended
in a semi-liquid flux paste. Heating drives off the flux and melts
the solder onto the copper traces or pads.

Surface tension of the melted solder will tend to keep it on the
copper but you'd want to put the paste on the copper fairly
carefully rather than painting it all over the board. Surface
tension can only do so much.


Regards, Bob
