Hi Dean, Can you please tell me how we could incorporate DPU to DPMO? Also, can you please explain the deviation factor DPU * deviation factor = DPMO ? Should we take dollar value or number of joints? Explain with calculations if you please. Thanks

You really sould get rid of the dehart unit. I'm sure your aware of its limitations at this point. Plus, as your finding out service my be an issue. APE will give you a trade in credit on the old unit to apply to the purchases of a new APE system.

Also in some instances a 10% decrease on glue size would be needed for the smaller S.O.T. sizes out there. If you are dealing with a good company to make your screen they should send you back a preliminary art work file on the Screen to be made so yo

Why don't you have stencil house make a selective wave fixture for your product so that you can avoid the glue problem. If it's a must for your process to have glue, you just add extra work and glue tended to contaminate. Just a suggestion..if you

You can get a better Kapton tape (you must be using the cheap stuff) that leaves no residue. If that fails then you can get edge maskers that slide overtop of the finger and they are reusable. Or you could get a solder pallet made for the assemblies

Dear Masdi, Perhaps you should check again your screen print process. Small amounts of solder paste under stencil can cause your problems. This paste is from previous printed pcb. When printing next pcb this paste attachs to places that it doesn't
