We have just completed a test for a leading manufacturer of SMT IC packages. There were some surprises. The carrier and cover tapes appear to be highly hygoscopic. The saturation curves for the tape and devices showed dramatic absorption at the begin

We have an old Conceptronic oven (Discovery Mark IV) which we use in the glue process. The video monitor just died. This is a 11 year old oven with a Goldstar model 1420 PLUS monitor. There are no specs in the manual and Conceptronic is not much help

We are using the omega meters to determine the solvent extract conductivity. The book is refering to standard MIL-P-28809 who specifies a 14 ug/sq. in. of Na/Cl limit. The past owner of our machine was setting the pass/fail limit at 3.6 ug / sq. in.

Ask your supplier if he will guarantee to cover rework, warranty, and lost business costs, if he's incorrect. Below 2uinch gold is very pourous and not worth anything in preventing corrosion of your nickel undercoat. 3 uinch has to be the absolute

We have evaluated 4 different AOI machines and the General Scanning 8200 machine was the best. Great G R&R. As far as paste height goes, it is very paste dependant. I recently completed a DOE comparing laser stencils to EFab, varying 0.5 mm pitche
