Can you please decrease the ramp rate of your reflow profile?In my opion,if you heat the pin too fast,the solder will drop for the gravity and the cappilary force can't draw it back.On the row with much heatsink,this issue won't happen,that's the rea

I don't know wat are the types.. but wat I can tell you is you need care while profiling them. it needs a peak of around 215-220 if Sn/Pb.. at the ball. So the plastic on top will reach a higher temp. Care must be taken so that it doesn't roast. al

I am interested in RoHS "through-hole soldering": We have a problem with solder wetting and fillet during selective and wave soldering, with a Ni/Au PCBA!! Different fluxes has been tested, but this is really a big issue. Now; there is only a few fl

In a time crunch, kapton tape works great. If you are using durostone or some material like that for carriers, make sure it is clean right after you machine it and the kapton will stick very well. We are low volume so we pretty much always use tape

DUCKMAN, your comparison is the same differnce. Meaning its not much of a choice: 1. 10 year old technology, no longer supported, spares hard to find, no software fixes, training etc...crappy hardware / software, lousey, overly complex feeders etc.

The biggest most important overall factor I have seen is the personel running and looking after the equipment. Any plan not involving them will probably not be effective. The front line people can probably tell you more than you can tell them. I hav
