The IPC-EM-782 reads as follows: the adjustment factor is usually intended to increase the Z dimension slightly, but brings the Z maximum up to an even equivalent. Example if Zmax is 2.100mm then you would enter an adjustment factor of .100mm. The ad

KS: You're correct. The standoff on a 1.00mm and 1.25mm BGA is high enough to allow cleaning. The standoff on 0.8mm BGA does not allow proper cleaning, even with saponifiers.

Improve quality with stencil design for inductor

Hello all, I know there are very skilled guys. Can anyone suggest a stencil design to avoid component displacement during reflow to improve tension of surface forces and selfalignment? There are cases where the inductors are shifted. All parameters

Hi, Depends on where in the world you're based, but in the UK you can pick up a decent Universal GSM1 for around �12K-�15K ($20K-$27K). We place BGA's, huge fine pitch IC's, 72mm connectors etc with no problem. I believe they do up to 100mm feeder
