Donnie is correct. "NO-Clean" doesn't translate to "no-residue!"..... who's giving you hassle about this - your ICT guys??!! Residue remaining on your PCB substrate is a function of many different things - flux deposition, solder mask (glossy means

Finally someone with great sense of what needs to be done! and wonderful sense of where we need to go.... If 2D was sufficient, HE would have made this physical world of ours 2D too.... (tongue twister, nay...) I agree fully with this Steve guy, 10

Hi Randy, No-clean flux needs to be activated in order to burn off the volatiles in the flux. This normally occurs partly during preheat and certainly during the reflow or soldering process. In most hand soldering applications, an operator applies

Thanks for your response. This is a DeHaart MPC-29. It has manual vision, no conveyor. When I bought it, only one camera was working. I fixed that, but while I was jacking with that, the electronic pressure regulator (spcjr) burned up without warning

We use SAC387 (or 96SC) and I found that the SelectX was only marginally effective and that other factors (varying the wave height mainly - we use pallets) affected bridging more. Also, because we run different products at the same time through the

Mervin, Love these machines, Speedline built about 3500 of them so I have lots to fix. Most issues come down to incorrect use or poor adjustment and alignment. Your description is a little vague, you didn't mention which direction the prints are of

Using no-clean flux will make the boards very difficult to clean. If you can switch to water soluble flux, your life will be much easier. The "icicles" lead me to think that the board isn't getting hot enough in the pre-heat cycle, and/or there isn

There are a number of different things to ask youreself here. What type of flux are you using. 330, 351, 310 etc. Do you have a hot air knife? As for the residue, that's gonna show on almost any wave soldered pcb. We have fought the issue for a long

Time, time, time. There just never seems to be enough!!! Eh? You�re correct. Depending on the material, some trays can take a high temperature bake, while other trays, in addition to tubes, and reels, require a low temperature bake. With this la
