Hi everyone I have problems welding QFN components in a 10-zone reflux oven, we cannot make a welding fillet that covers the entire QFN pin. Currently we use paste T4 - 63Sn / 37Pb. I enclose the curve of the oven profile. Any help or support on this

We are having issues with solder flooding some through hole pin receptacles which have an organic fiber plug on the soldering end. Anyone else use these types of receptacles and soldering with selective solder. Appears the plugs may be not sealed w

I'm looking to gather some opinions. The C.M. I work for has always used the 3D Stereo Binocular Microscopes. There is a big push towards LCD Camera scopes, that is meeting a lot of resistance from the Solderers and QA. What is the consensus out ther

I have not used many camera/display scopes (have seen a few demos) but I've never seen one that gave me the same quality image as a binocular scope. I even take pics with my phone through the lens and they don't come out half bad, even after cropping

Thanks för the reply. I can't find any info on any feeders/magazines except for the Agillis. What is the difference between tm8,tm8c and tm8fc? Tried to search for Fp feeders also no luck. I've got an account on Myspace on mycronics. There's also

Thanks for the info. In a past life I ran everything WS and washed in a batch wash using saponifier. I'm surprised I never saw anything then as we would regularly wash boards assembled on only one side. Unless it's specifically washing in DI only.

Does anyone else have issues of certain cover tape that gets stuck in and around the feeders? I have been fighting these 2 tapes all day. I try to tape them to the pocket tape with a twist, but it only works so long. It happens Either because its s

This happens with either old tape, the cover tape doesn't stay sealed on the left side, or is the seal is too far to the right, the knife lifts the cover tape. There isn't much you can do in this case. Your choices are: switch the component into an A
