According to our plant drawings: MV2VB 23' 8" X 6' 11" GSM1 8' 6" X 5' 6" A GSM2 should be the same size as a GSM 1.

Nitrogen gas and Tombstone defect

Electronics Forum | Tue Nov 29 14:57:45 EST 2011 | jlawson

Sorry on N2 and tombstone, many other aspects cause tombstones and n2 in itself does not cause tombstones. It can help make other bad variables tip over edge to cause tombstones more than with no N2. Get these right then N2 is not issue.

Any PCB manufacturer can do 8 layer 1.0mm PCB with 2/2mil line?

Silicon contamination in solder joint

Electronics Forum | Wed May 28 14:35:47 EDT 2003 | davef

Wow, you're very correct. I guess we use silicone to calibrate our machine, as follows: XPS spectral measurements of dimethyl silicone should include O(2s) at 25 eV, Si(2p) at 102 eV, Si(2s) at 153 eV, C(1s) at 285 eV, and O(1s) at 533 eV. The C(1s
