Has anyone ever heard of testing solder paste quality by pasting a board and making a determination of the quality by measuring paste height and width after the board is pasted. Would you consider this a valid test for solder paste testing?

A solder wetting balance will indicate a time of less than one second for wetting to occur to a solderable surface. The additional time is required to get the metalized surfaces up to soldering temperature. A single sided board has very little mass a

Hello, Attached is the X-ray picture of a SMT transistor. Please give me your opinion whether this is a good solder or not. From my view, I did not see any solder in the middle pad. I feel it is a production problem. But someone told me unless you s

I am having a problem soldering some thermistors, 0805 package. They appear to be comtaminated, is there a really agressive flux I could use to help solder these parts.

I am soldering with a softbeam laser and often get a flux/solder build up at the end of the feed tube. Seems better when we use Senju wire but this is very costly. It seems like we have tried everything to resolve this. Would appreciate assistance on

Can you get me a recommendation regarding a Micro BGA soldering. It is apparent there is a problem and I want to insure success by following recommended practices. Is there a particular solder mask configuration recommended, as far as stencil thick

I side (not that we every actually choose sides here) with the other poster re: reducing solder volume. There is a solder manufacturer that advertises regularly in trade mags. that there are "Absolutely! NONE....NIL....NADA.....mid chip beading/mic

This looks like it may be a good application for an Air-Vac or Wenesco type solder station. It is a solder pot that has a small motor to pump solder up through a chimney. You can put different nozzles on the top of the chimney, so you only apply sold

While it's possible, we don't think that soldering a wire of this low of an AWG to a board is a good idea. We're concerned that mechanical vibration and heating / cooling will stress the solder connection to the point of failure during routine table

Looking for the best choice in books on soldering processes, primarily reflow but wave is going to be with us for a while so..... If you had to buy one today, which would you start with? Here's the list I gleened from the archives: Coombs, CF, "Pr
