Don�t your recent findings on soldering defects point towards less need for AOI? Besides that, I imagine that with 100% control and having only good prints being processed while the bad ones getting washed and reprint you will see this magical 0%. Sh

We leave the next days quantity out overnight. Never had to do more than 4 kneads. On the inline we don't do any and the VMP 100s we only do one. Only seem to require kneading on the old clam shell printers - don't know why! That's with Indium SMQ 92

On an assembly reflowed in air saw the same thing: 0201's with a grainular solder joint, but 0402's and above with perfectly formed joints. Reflow profile all within acceptable tolerances. Reflowing in nitrogen solves this problem, but increases t

Hi everybody, Does someone have experience in the assesment of Surface Mount devices? For the moment we have the Must System II of Multicore but it is not effective to assess the solderability of Surface mount devices. Indeed the conditions are not
