First you need to call your flux supplier an find out what your top side board temp should be for the flux you are using and what the dwell time should be.

One other thing you may want to look at is your nitrgen settings and the difussers. If you don't have them correct, you can also see bridging and icicles.

Consider the profile recommended by your solder paste manufacturer to be the starting point to begin tailoring ramp rate, dwell times, and temperature excursions to meet the requirements of your boad design, the capabilities of your components, and t

I used a CamAlot 5000 to apply conductive epoxy on an aluminum substrate about 4 years ago. I used the largest diameter nozzle CamAlot had, and I bumped the dispense and dwell times way up. It was the slowest stage in the process, but it worked out o

Christopher, Is it possible to get some more info like type of no-clean flux you use and process parameters topside temp of board before entering the wave and dwell time in the wave. Patrick Interflux USA, Inc.

Ah, yes...the solvents. I'll bet with SS machines vs. WS machines there is way less dwell time at preheat so you don't evap enough solvents. Do any of these SS machines use force-convection preheats or are they and IR type?

You also would want to talk with your flux supplier. They are usually knowledgeable in the proper application of and heating of their fluxes. Usually, insufficient solder in a wave process is related to insufficient preheat,dwell time, and flux app

Il ne pas de quois. Two most important parameters are: * Solder temperature * Dwell time Immersion depth [1/3 to 2/3 of board thickness] has the least impact of any variable in wave soldering.

Has anyone ever seen a bulbous joint (on 1 side of 1 designator) on every board? I checked the preheat profile at the wave and have played with dwell times but can't get rid of it. I checked the archives and didn't find much. Any help would be apprec
