The ENIG process will yield between 3-7 micro inches (110 - 275 microns) of gold over the nickel barrier. This thickness range is pretty much the limit as this is a self limiting displacement reaction process. Once all surface nickel ions are repl

Be current.......Is my best suggestion. Electronics Theory and three stage audio amplifiers are great for class room environment but does not 100% apply in manufacturing. Teach through hole and SMT related classes. teach manufacturing. There are tons

We have been encountering diminishing ball shear readings these past few weeks, despite the fact that we did not change any ball shear tester parameter. Our reflow parameters are also within spec limits. ( 210-220 deg C max temp. and 40-60 sec dwell

Just curious, Are any of ya'll coming out here to the Chip scale and BGA National Symposium out here in Santa Clara, Cal-i-for-ni-yay next week? I'm a-goin'...gonna learn more about them little buggers...I just know enough now to be extremely dange

Hi Everyone, We plan to build, for reliability/experimental/research purpose some CSPs (namely Tessera microBGA 46-I/O 0/75mm pitch and TI 64 I/O 0/8 mm pitch). the various factors that we plan to evaluate are the reliability and assembly concerns fo

| Does anyone have info on any of these systems (good or bad). We are looking at these 3 types for a new SMT pnp machine. We are low volume high mix. | | Thanks, Dave | I may be able to supply you with some valuable info on all three manufacture
