Hi, think there's a guy who is a SMT consultant, he also sells SMT mfg solutions. try website : http://www.bobwillis.co.uk dunno how good his solutions are, never tried em b4. He seems to have remarkable popularity, so give him a shot. I recall

What type of wave machine? Does your machine have a pump speed dial? Does your machine have the ability to raise and lower the pot? Raise pot to as close as possible to the pallets/boards and make sure they can pass over the nozzle without hanging o

Ron:It�s tricky to get what you want with this foamfluxers espacially using pallets. They got to be cleaned regularly. Most of the time excessive residues are removed using brushes which adds another process step. It should be better using a sprayflu

Thanks everybody for the help! We are still working on the bottom side, but the top side solder balling seems to have gone away for now. We flattened out the middle soak zone of the profile, so that rather than an even ramp up, the board heats quick

Steve, Currently we are using selective pallets and the best piece of advice is to find a supplier that will be able to handle the requirements of the selective wave process, for example proximity of chips to PIH devices, and pallet thickness etc. We

| We are wave soldering a board having 24 similar thru hole connectors on it, using a wave soldering pallet. The problem is that one particular pin of connector in around 6-9 connectors get excess solder on the bottom side. I have tried all the par

The parameters which effect the problem you are having are flux and contact time try first increasing the flux you are applying. Next reduce the contact time in the wave by adjusting the back flow plate. If the problem is a jig design check out the j

Hi, I have loads of experience with QP132's. You can change over product quite easily depending on a few things: - � The board sizes should be the same otherwise pallet adjustment can take an hour or so. � If you can fit all the feeders on one set-u

Hi Dave G, This is an interesting problem.. I can only add the following: - Try trimming the pins and see it this helps.. sometimes the decreased surface area will lessen the surface tension enough to minimize the effect of bridging. - As Dave F was
