If u don't have any box oven either, why don't u just use your wave. Turn the fluxer and the solder pot off and run it through your preheaters.

Jeremy - What's the process flow on these modules? Are they wave soldered? What is the board finish (ENG, HASL, etc.)? Glenn Robertson

My company is currently experimenting with with a 310 vox free water based flux on solder waves using Infared heat instead of forced convection. I'm interested if anyone has tried this and what results did you have

Larry: I'd like to see your angle increased generally and that could fix your problem. Lots of other things can cause skips, such as: * Wave height, your might be high with 2" of contact * Flux contamination, activity * Component contamination * C

For the Transition Automation pallets that Chris mentioned, they can be contacted at www.boardlok.com, or 1-800-648-3338. "SMT pallets", as compared to those specific to just wave solder, are becoming increasingly popular. Good Luck

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.

We are using a glue and wave solder process for primarily chip components. Our products do not use any fine pitch components. What would an acceptable benchmark for the placement defect rate be? 50 DPMO? 100 DPMO? 200 DPMO? Thanks in advance,

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.
