Various solder metal supplies sell pre-forms as loose individual shapes, usually donuts. The loose performs then are placed on the connector leads. If you have any volume at all, you would want to look at a �shake table� that would vibrate a batch of

Here is some thing that I wrote a while back on solder beading. First what is a Solder Bead? The term solder bead is used to differentiate it from solder balls. A solder bead is a solder ball but its location is normally constant unlike solder bal

Hi, I have received a report form a board supplier, analysing the reuslts form non wetting problems we have been expereincing with their boards. I assumed it was due to the gold layer being too thin, thus allowing the nicklel layer to be exposed and

We've never used the 99*C lead-free solder you mention. We have used a leaded solder that can form a 93*C eutectic solder. So, we had to be sure the service temperature [of the solder connections] as below 80*C.
