Are there specifications or recommendations for electro-deposited tin-lead plating thickness on austenitic stainless steel that would provide a shelf life of 1 year? 6 months? Would 2 to 3 microns (78 to 118 micro-inches) 90/10 tin-lead over 1.27 mi

Our new PCB supplier can give us a 20% price reduction if we convert from an ENIG finish to a FLASH gold finish. My uderstanding between the two is as follows: ENIG - Nickel is plated over copper and then immersed in Gold which forms a self limited f

TopLine will exhibit its MSC Series of Micro-coil springs, a novel interconnect for CCGA (Ceramic Column Grid Array) IC packages for harsh environments. In tests using daisy chain test vehicles, Micro-coil springs absorbed extreme shock of up to 50,000g before failing. Commercial applications include aerospace, avionics, military, down-hole oilfield drilling and automotive electronics. Test results were initially presented at IEEE CPMT 2012.

Smartphones and tablets require very high flexibility and severe bending performance ability of the flexible printed circuits (FPCs) to fit into their thinner and smaller body designs. In these FPCs, the extraordinary highly flexible, treated rolled-annealed (RA) copper foils have recently used instead of regular RA foil and electro deposited foils. It is very important to measure the Young's moduli of these foils predicting the mechanical properties of FPCs such as capabilities of fatigue endurance, folding, and so on. Even though the manufacturers use IPC TM-650 2.4.18.3 test method for measuring Young's modulus of copper foils over many years, where Young's modulus is calculated from the stress–strain (S–S) curve, it is quite difficult to obtain the accurate Young's modulus of metal foils by this test method.
