Milroy, Another thing to look at is your wave profile. Check speed and pre-heat, if flux gets burned off before reaching the wave then bridging is expected, a common way to check for speed is to time the point of first contact through the sub-merge

Howdy all. The question that I have is on wave solder pallets. I'm getting quite a bit of flux trapped on the pcb where it contacts the wave solder pallet. I have an appropriate profile for my assemblies, The flux that i use is Kester 920-CXF No Cl

Vlad, Reduce your aperture opening in the stencil, this will give the stencil a good seal around the specific area of concern. In a wave solder environment, solder balling top or bottom surfaces in a wave pallet is caused by excessive flux burning o

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

I've heard of reliabilty problems caused by wave soldering melf's as well. We don't put Melfs on the bottom of our PCB's on newer designs. We only have to deal with gluing & putting them through the wave on some of our older legacy designs. Increasi

If you add any "flux cored" wire solder to the pot make sure you have ventilation as the flux will burn off and smoke like crazy. This solder pot is like any used in a wave or selective solder, no flux. The flux is added to wire prior to di

1. SRT has been recently calibrated - problem is too many hands in the machine and careless mistakes. The profile is good and has been recently checked by a fellow from Genrad. 2. We are relying on the left over solder from the previous joint and

Back in the days when pots, skillets, etc. were made of cast iron, vegetable oils were used to "season" the iron to prevent rusting and also from the food sticking to the pot during cooking. It would be reasonable to believe that you could use the sa

Hi, Your right guys, and we turned off the chip wave, and most of the problem went away. It looks much better, and we are getting a slight bridging on a USB connector at the front edge of the PCB and a little adhesion, but not any where as much as w
