Solder balls with wave soldering can have different causes. The two most important are the solderresist and the flux. I have similar problems, after changes the flux type 90% off all solderballs are gone. KR, Joris Groot koerkamp

It should only be a visual thing. What may be happening is that all the thermal energy being driven into the wave solder pallet to get good soldering is causing the no-clean residues to burn up a bit, causing the discoloring. Check to see if they hav

yes SPC can be used on a wave solder machine, you should use a c-chart to monitor the amount of defects per board or group of boards, this will let you know if your process is stable, as you improve your process you should re-calculate your UCL, hope

I agree with Joris. But to add to his comment, the type of finish also has a direct affect to your wave solder process. Going from a gloss finish to a matte finish may help a lot. As for humidity affecting your wave - I doubt it. I use a water

Hey all! The wave solder warrior is back. I have found a flux which leave almost no residue (the least yet), but because of its super low solids content I absolutely cannot get topside fillets. The multi-layer, two sided board is on a pallet w

Hi everyone, I am looking for a reliable company (preferrably on the west coast) that can make Wave Solder and Press-Fit fixtures for our back-plane division. I need a reliable source that can take our data and produce quality fixtures in a 5-7 day

I am having problems with a product we receive from our overseas plant, where there is excessive "dullness" of solder joints/metal surfaces after running a board on a pallet through wave solder. Seems to be an issue of the pallet, as the solder appe

Hi everyone We plan to use on our smt line sac 305 and on our wave soldering sn100c. Will there be a compatibility problem if we do make touch up with sn100c on smt or touch up thru hole components with sac 305 ??? Thanks for taking time to reply
