Hello there: Could anyone help: 1- In a double wave wave solder M/C, is possible to completely eliminate the second wave without affecting the quality of the solder joints? 2-From a quality control prespective, what is the minimum accepted length of

Hi its undercured solder resist which leaves a clear waxy/oily residue and can be seen as brown tar/oil in the molten solder wave. This also causes MicroSolder Balling and some snail trails of solder pick up and worst case bridging and peeling resist

2 more statement that need consideration in the logic: 3. heating up solid solder consumes more energy than heating up molten solder. 4. keeping solid solder at a constant temperature consumes less energy then molten solder. Result: We keep our pot

So, there is a crack or gap between: * Solder and component termination. Bingo Correct? Describe: * Coarseness / smoothness of the metal on the termination underneither the crack. * Solder left on the termination. Unfortunately at 45X I can't rea

You say its in both smt and through hole, but, are you waving the SMT parts as well, I assume yes since you think its dross in the joints. Questions: 1- do you have higher mag scopes that you can zoom in a little more to see if these are voids or dr

Are you spray fluxing ? If so, check that you are getting flux onto the whole pcb uniformly.... That BLT flux is a water based material, are you getting rid of all the water in the preheat before you get to the wave ( can you hear any spitting as t

Hi, My name is Branden Spencer and I am a jr. engineer at TTM technologies. We are currently having and issue with our wave solder process. We are getting what looks like either solder dross or voiding in our solder joints (through hole and SMT). We

we don't have a nitrogen generator installed yet. The solder wave supplier recommends 99.99%. we hare received several submissions for nitrogen generators that meet the requirements.

Yes pads are still gold after the wave soldering process even if you wave solder a pcb several times. I have tried soldering using an iron and the solder takes to the pad as you would expect. This happens on all boards of this type and all boards are

Could you not just switch to alcohol based flux? If your prob is getting the water off the board prior to hitting the wave, maybe you could install some type of convection to aid in this? Russ
