Alot of QM's and QE's are typically failed Engineers who lack common sense. They don't understand that measuring in DPMO's (versus DPU's) "normalizes" your data for Printed Circuit Board Assemblies (PCBA's) so that if you have 10 defects on a PCBA t

If this is a one time rework might I suggest farming it out? 100pin QFP can be taken off no problemo.. Putting it back down properly and then hand soldering??? I wouldn't want that job. You need excellent placement and imaging and your not going to

Full disclosure; I represent ASYS in the southeastern US. Depending on PCB size and mark requirements you can get a laser marker for under $100,000. It can be set up as an island to mark batches of PCB prior to them going to the assembly line. ASYS a

I have a small 5mmx5mm 32 pin QFN I need to program and want to find a way to do it automatically. Companies like Xeltek charge $100,000 for an automated programmer and I think it can be done with a regular pick and place machine by placing QFN into

The boards are expensive because they are your product... covered in circuitry. A 2% scrap rate costs twice as much as a 1% scrap rate. Say the parts on your consumer electronics board cost $5. A machine that makes 99% good boards and 1% bad boards

I use the Olympus C-2000 Digital Camera. It has 1600 x 1200 resolution with 2.1 mega-pixels. Nothing gets by this camera. It should pick up all of the detail you need. This model is a bit expensive though (about $ 1,000.00). It features a nifty

I have oftened wondered how this industry lets its workers get away from being responsible. The best way I know of is to have them buy their own tools. Just take a look at the trades - carpenters, plumbers, welders, sheet metal men, body repair, mech
