I have found that preheating the solder pallets prior to use helps cut down on the solder balling. Also, we do not cool the pallets between passes and we use a spray fluxer because a hot pallet will knock down the head on a foam fluxer. We use WS f

If you can, attach athermocouple to the locations where you are getting solder balls. A previous product I had showed the same thing and we found that we had inadequate preheat leaving the liquid flux to splatter when it hit the wave. It could aslo

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

They're IR, bottom side only. Frankly wave solder is not my forte (there are those that would claim nothing is), but I've personally been tasked with developing a process to do reliable, high volume bottom side SMT, so I'm drawing a lot from the tec

Have you check the flux gravity lately? If not, Check the flux gravity every 6 hours to make sure proper parameters are meet. Here is a list of things that may cause your solder ball problems; Excecive heat, defective fixtures, preheating temperature

We're trying a selective soldering pallet for the first time with mixed reviews. Are solder balls a prevalent problem with this process? Most of them seem to correspond with pallet wall locations....is it too much turbulence from the rotary chip wav

At the price of Durapol we'd never get the OK to have them made. The Al fixtures are cheap and a quick turn local item. As dense as the pth parts are I also don't think there'd be any room for any holes which I really think is the answer as far a

Steve, I wave solder most if not all our boards with selective wave pallets. I did not catch if the solder balls were on top of the board or on the bottom but that will make a difference on what to do to get rid of them. Pallets are good and bad. On

Hello, I am looking for someone who has experience or know of someone who could service and repair some selective soldering machines. The machines are the K.I.S.S-101A and K.I.S.S-101 selective soldering machines. My boss and I have been searching ar

Thank you! I will look into it and see what I can come up with!
