Thanks SuMoTe, I've already tried fluxing various boards (new clean ones and older ones) without turning the waves on and with different temperature setups (within the suggested params from Alpha) in the preheat zone. The results were in many cases

| I am wave soldering a single sided through hole PCB array with (6) .040" round diameter pins that sit .5" off the PCB, and .080" apart. The problem being experienced is that solderballs are appearing on the end of the pins. I have tried decreasin

We are running RoHS compliant & non RoHS compliant assemblies. We buy our bare boards from one supplier that only manufactures RoHS compliant boards using a Sn100 finish. Is there any known issues running leaded solder on a Tin finish? Does normal

Folk's, I'm in need of some help / direction. I'm working on my thesis for a masters based on looking at the effect's of the solder resist promoting / reducing the amount of solder ball's during wave. I'm looking at thing's like colour, texture, com

All y'll: I could use your input on determining when to skim dross from a wave solder pot. On one hand, dross protects the surface of the solder from oxidation. On the other hand too much dross may affect solder joint quality. On another hand, ov

Hi All - My question is how do solder balls form and stay in the vias? The assembly goes thru SMT top placement, reflow then thru hole components mounts on top side as well. The board is sent thru the wave solder process. Has anyone experienced this

SSD can be used on both sides of the pcb. Although , it is not very logical to use it on the bottom side of a pcb that has numrerous Through-hole components, that are to be wave soldered. There are many advantages to SSD. The amount of solder is much

On finding baking recipes in the fine SMTnet Archive, your problem is not in the flex portion. It's in the rigid [FR4] portion. On baking advice from experts look here: http://www.circuitnet.com/experts/EQ10120.shtml Finally, on reworking your ou

Techspray has a broad line of peelable solder masks. We use the Wondermask P for masking conformal coating as well. Call the company or rep to determine which product is best for you. I am not affiliated with Techspray in any way. If you get tired o

Have you heard about the stamp soldering solution for THT? With a 25 second tact time maximum, for any size board and regardless of the THT component count, and much better yields than a fine tuned SMT process, stamp soldering can remove the largest
