Mike You get what you ask for. We ask for 0.001 inch minimum. If your supplier's published process range allows thickness below 0.001 inch minimum, you need to define your own acceptance criterion. We don't use average measurements in lot inspect

You can do a destructive test to sort of check your process. Break off the flipchip and look for voids. I have used Namics 8437-2 for the last 7 or 8 years. Good stuff. Flows under a 0.001" gap with no voids. Chris

I use Namics 8437-2 for micro BGA and flip chips. Will work for QFN or MLF after soldering. Flows well under gaps as thin as 0.001". Cure in 5-10 min at 150 C. Rock solid product. Is bit expensive. Is from Japan.

It read to .0001 and was repeatable to +/- .0005. As the SR coating got thicker, it was more sensitive to pressure since the transducer (ours was a 1/8" dia.) would press into the coating. You might request a demo from a vendor and see if it is a f

Hi Ameen, As I said before my defect rate is 0.001% and i am planning to reduce the stencil opening only. Will share the result once I implement it. Expected to complete it withing next week. Thank you.

I need a good chuck, new or used, for a QUAD 100 pick and place. The chuck size is 00-001XG. The one I have has worn fingers, bushings, and leaks air around the nozzle. How difficult are these to rebuild properly? I would appreciate hearing from a

If you lay a flat edge on the PBGA, it is visibly warped? How much of a warp? 0.001, 0.010, 0.050 what? What is your pcb temperature just prior to entering the spike process (zone or step or what ever you call it)? Is it between 165 and 175 C?
