A common bottomside heater configuration is IR-Convection-Convection. One of the big advantages of the IR zone is its ability to allow the flux carrier to spread and dry slowly before the board reaches the convections zones, which can blow wet flux c

Hi all, Need advice how to fix RJ45 short issue after wave solder m/c .Few actions taken to resolve this issue but the outcome was inclusive which was 1. Modify wave pallet 2. Change conveyor setting from 0.8meter/minute to 0.7 meter/minute 3. Clear

Bridges are front to back. To me this seems to indicate thieves would pull the solder away from the pins. I feel I am correct in that theory. Yes, it would be a good idea for us to bring in a consultant but I have the opportunity right now to make b

I agree with DDave, You have something else wrong! .100 dips with .05" lead protrusion should not bridge (in fact I would think that it would be almost impossible). Tell us about your machine, (laminar flow, A-wave, etc.., size of nozzle, wave heig

Given that you are bridging front to back, contast the situation with the thiefs used to prevent bridging when wave soldering SOIC. If this is reasonable, the thiefs should be located behind the trailing connector pins. You can prove-out this [and

Tell us more about the location of the bridging [ie, front-to-back, back-to-back, front-to-front, etc]. Thoughts are: * Your annular ring around the hole seems large. You have 0.007", consider 0.003" to be the minimum. Your board fabricator can gi

I need some input on what good solder thieves dimensions should be. I am limited to solving my bridging problem with solder thieves; all process/wave variables have been adjusted to try to solve this problem. There are several of these connectors on

Annular rings are too big, it is acceptable to have shorts on the common conductors. I would be willing to say the "other" supplier may have modified the artwork as well. Good fluxing, preheat and proper immersion depth are key to eliminating short

That's where this website falls short. Sorry to b*tch, but there's lots of people who post here whose primary language is NOT english, and you know what they say... "a picture is worth a thousand words." Original Poster guy...try "Image Shack" to s

We have a problem with soldering of a 96 pin header connector(9001-11961c00l1a from kingmate) we use 3 different wave soldering but in all of the machines we have many short circuit between the pins . the wave soldering machines that we use is fr
