Bruce, regards to all who are trying to help and have great input, with those type of lead length, I would be very impressed to see you get rid of the problem, and as the others said, no clean in a foam fluxer, not good but workable.... the real issu

Could anyone give me a basic profile temperature settings for a conceptronics 7 zone oven and speed? I have the first couple of zones ramped up to get to the soak temperatures. Is this correct or should I start out with low temperatures and graduall

The temprature for the first zone should be less as the PCB entering the oven from the ambient shop floor temprature would suffer a thermal shock from a higher temp. Experience must be gained from profiling a board with thermocouples, otherwise you

We typicaly have 6 basic ones we work from. We can not have one as some of our boards are simple smt to Large ground plains to rf shielding. We also monitor board color and component types...Obviously BGA's are treated a lil different. Some boards ne

Louis, For whatever it is worth, When I have $5000 parts I don't even mess around with a rework station. I would mask off any heat sensitive components (We use water soluble masking like that for wave soldering) and then process through the oven yo

Anyone using these 2010 resistors? We just tried them and they bow like crazy during reflow. Not very good looking. Profile meets manufacturers spec. The part solders and works fine, but I'm a little concerned about putting anything on a board th

We have seen "coplanar problems" on BGAs supplied by some suppliers. We have seen large enough spere variation to cause opens with our standard .006" paste process (paste and profile work fine "most" of the time) . Although not an extremely technic
