The Manncorp machines are Autotronik machines re-branded. These are Chinese built while pretending to be German, they are seemingly capable enough and do come in at very attractive price points. The FLX from Essemtec is in many ways a slicker machine

It sounds as if you have your AOI set up off-line, and you're "AOIing" a sampling of the PCBs produced. If that’s the case, then the responsibility of who drives the inspection really depends on how you configure it. If it's based on the number of P

I am trying to determine who out there is reballing devices below 0.4mm in pitch. We have been reballing as small as a 4-balled 0.15mm 4 mil ball diameter area array devices using an adhesive-backed reballing preform. 1. For such small devices we h
