Hi, Try to check if there is water absorbed in the flux or the humidity around the wave area. possibly plating on barrels that might be damaged?

This might be a trival mundane suggestion but try to use non conductive plate to hold components. Probably even made of the pallet material. I am sure your pallet fabricator will have tons of scrap and he can help you find one. T

By the way, what type of preheaters do you have? IR? Convection? If you have IR, there may be a way to cheat. Vince W

I attached a RX picture. A lot of voids and micro balls arround the flux residue. What do you think, relow temperature reflow or OSP poor weeting.? I appreciate your comments. Thanks,

We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te

Jim, In most cases if you can eliminate a process you will save money. With that in mind, an all surface mount or all through hole design is prefered. There are alternatives to that rule, like hybrid designs that can be pin and paste soldered. It al

Jim Consider issuing a purchase order to your assembler for the purchase of selective wave soldering pallets required to solder your board. That way, you: * Own the pallets. * Can take the pallets with you should you decide that another assembler

There are a few emerging technologies that have been growing in popularity for the past few years. Pin through paste, press fit connectors and selective soldering machines seem to be displacing custom fixtures. Most of the mixed technology boards o

Steve , I agree with all the responses you have received. Randy Villeneuve is absolutly correct in all of his assesments and I would consider him an expert with the process , Gris is correct about adding a "heat sink" to the process complicating pr

Randy, Steve & all, Can you guys point me in the right direction when it come to using selective wave soldering...I am trying to get in-depth information on the Pro's & Con's of having our supplier use this process for our PWA's. (I can see there ar
