Your customer is very unreasonable to demand void-free BGA SJs. Minor voiding is not a condition for rejection per IPC-A-610D, J-STD-001D, or even J-STD-001DS (Space addendum). Having said that, let me tell you that the voiding has little or nothing

Yup, that seems to be the procedure in the manual. But, it gets complicated, as the head has a rotation, the part has a rotation, and the MA station has a rotation, and it gets pretty confusing to figure out which way to tweak the offset values for

The programming time depends on the system you are using. I use YesTech. It has been a reliable system for catching the majority of production issues. The programming time on this system is around 20-30 min. with a full library, meaning you don't

A couple of things: Does the cap break if you try to remove it with hot air? If not, than you are breaking the caps do to mechanical stress. We have had similar issues. I don't think your board is suffering from mechanical stress from depaneling o

There may be a better way, but this is how we do it: We have one SMT line and ALL SMT parts are kept in the SMT area. There is no kitting of SMT parts...only through hole, etc. For each SMT part in our ERP system, we set for backflush. That means th

How do you track your current reel issue/utilization from stock to the floor? I assume you issue the parts to a work order of some description (probably tied to a sales order, and a customer purchase order, for accounting purposes). So...from your
