We are in the process of launching a new product and found reflow solder issue with one of the inductors. I have set oven profile to paste specifications. I just finished profiling with thermocouple under problem component. All other components ex

BTU as well as most oven manufactuers have great products. If they fit what your looking for and can give you good support(preferably local) then you should not really see any quality problems with their products. With the oven max temperature of 300

| first of all what is the technical term for the small amount of solder on a plated pad. we are getting poor screen printing gasketing on a 20 mil qfp due to this solder not being even or too high in spots and not covering the length of the pads. an

should have ask the technical support personnel from Kester to come over to your factory and solve the problem on-site. Let them see what is wrong with their product, then they will improve it further....or straight away tell you they do not have sol

you using a ramp soak spike or ramp to spike profile? you may be burning out your flux in preheat if you ramp to fast or for too long, most pastes have 2 activation points for their flux one at low temp and one at higher temp. Try a ramp to peak pr
