Only used adhesives once and it was a disaster. I don�t rearly have much experience but the real problem is everyone wants to compare adhesive with solder and they will not give the same results. There is a good book on adhesive check out my book re

Bob We are just starting to look in to this process and have been told that it can't be done using a stencil to print the solder paste onto the PCB (of course it was by an equipment manufacturer trying to sell a paste dispnecer). Is this a far commen

That�s a good question which I will leave to others to debate further. I feel that there will be a need to examine and understand all the issues with lead-free and have as many practical solution as possible ready rather than waiting. There are sti

Do present reflow and wave solder equipment currently processing tin-lead process need to be replaced when migrating to lead free process ? Is there any equipment (reflow or wave) out there capable of processing both leaded and unleaded processes wh

The process is not that difficult so have a go as soon as possible. Take a board wipe some paste on a board stick the part in and run it through the reflow process. Don�t worry about balling just see what you get first, that what I did first ! The m

Bob, I attended your PIHR workshop at Nepcon a few years back. At the risk of making a shameless plug, I must say that the presentation and the materials used were some of the best I have seen in my many (20+) years in the industry. The video that is

I have 25#'s of bismuth in my shop. I wanted to add some to my 63/37 till it was eutectic. This would allow me to lower the waves temp. Can I do this and still meet standards? Also would it make the solder joints to brittle and would discoloration be

I would have to agree that the leads are probably geting to hot, but there are many factors that could be the root cause. I would suggest doing a experiment with a solder sample and make 2 recipes. One with a relativly cold profile and one with a r

You need to have a way to qualify and monotor your process. X-ray and ERSA's fiber optic inspection thingies are two approaches for doing that. There are lots of good x-ray machines out there. Get a transmissive x-ray machine with resolution of 10

Has anyone heard of a single or double tray holder plate for Siemens Siplace equipment (either OEM or aftermarket). This would be similar to the Universal, Quad, and Zevatech platens for trays that just clip on to the feeder holders. Have only a co
