When you go repairing resources like one time copies of an installed OS for a machine like yours , you have to treat it like your life depended on it. So get a copy of the harddisk before you attempt to repair it no matter which methodology you use.

HI, The short answer is, "whichever machine finds your defects." I would suggest evaluating machines based on a common vehicle. Make a bad board and identify the defects. Make a good board and have your vendor teach and tune the machine to the goo

We have an ERSA machine here where we have solder "spikes" occasionally. We have made sure our flux is dispensing properly, we have adjusted z axis speeds, our preheater is heating properly, adjusted XY speeds, etc. Can anyone think of something we m

We are using Austin American Technologies with Petroferm solutions and have excellent results using the same two types of solvents for cleaning stencils, adhesives and miss print boards. I average about five hundred cleaning cycles before we have the

All, I think we have missed the purpose of this thread. It would be great if we had the luxery of only running product's that make us look good and don't challange the machine's abilities( or for that matter our own). WE DON'T. If this fact has been

We like our AOI from Cyber Optics but only use it for process prove out. I would rather have a solder paste inspection system in line. The cost of AOI is killer. A new process is to embed a UV signature between the components pads and when a componen
