We use the flux Cobar 94-SEL with excellent results. It is a special flux for selective soldering process. When the temperature of the board with flux (preheating or during soldering) reach more 130°C, the rests of flux are deactivated (no more dange

We are currently looking for a new vendor who specializes in selective wave solder fixtures within Southern New Hampshire or Mass. Can anyone recommend a good supplier(s)?

Nice to have you back on SMTnet. Some of the newer folk have missed-out on the solid contributions you�ve made to the Forum. The chicken wire cleaning basket was a classic!!! [It�s a shame that the folk at SMTnet can�t recover those files.] We bu

Earl & Jeff Our machine is different than the Electrovert Solder Pak in that it is does not behave like a "volcano". Jeff, please contact me if you have safety concerns as perhaps you also want to consider our equipment. | | I'm trying a second ti

Hello, I have a problem with the solder paste process, I need a solder paste with no Start-up Time because We do not work 24 hours in the manufacturing process, we works only 8 hours a day and at the finish we need to store the paste in the refr

Hi rob, Thank you very much for your response. Profiling was made exactly on the pad, which showed dewetting, so the values are mentioned for this pad. PCB's is about a week old. It is possible that the surface of pads is already oxidized? I will t

You might want to consider using a stepped stencil. We have tried using a 5 mils with an increased aperture size to compensate for the lost solder volume, if you were to use a 6 mils. While the yield was good, we'd still get random opens. With a 6 m

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. any

I use a stereo microscope (Mantis) and find it way better for soldering/rework than a camera system, which we also have here. The camera system does NOT give you the same 3D-type of image that the Mantis does, BUT, there are times when you are inspec
