Hi Harrit, We are processing SMT eleco's normally - up to around 8mm in height, the larger sizes can still be avoided and are through hole as the cost of them outweigh the benefit of surface mounting them (although we did get good results on test fo

It depends on a number of factors - including as Russ pointed out, complexity (sometimes you need to create very complex profiles if you have large BGAs and other such components, which require at least 7 heated zones), then you have size, required l

these are two separate things, your MSA is measurement systems analysis, moving a machine won't change the way you measure your machines performance so you don't need to do MSA again. you should check machine capability once a machine is moved thoug

When a hole is drilled during board fabrication, it can transfer resin from the base material (eg, FR4 core or prepreg) to cover the exposed edge of conductive material in the wall of a drilled hole. This is called resin smear. Etchback is a control

Hi AJ, Depends on what machines you are running, how you run them, and if you have the spare components on feeders lined up ready to go. On a volume job using CP's using both feeder banks on change over I'd be upset if they stopped for more than a

Since I asked the question - here is what we have identified. We are doing what we call a jump score. Routing critical areas with v-score in non-critical areas. We have optimized the v-score depth as much as we can without having separation through h

Good morning, My advice is to put two Topaz-Xii in line. Machine programming is rather easy (with PPS and GPP that AssemleOn offers), but final teaching on machine is strongly required. If you want to prepare programs fully offline you�ll have to pu
