Testing Printed Circuit Boards for Creep Corrosion in Flowers of Sulfur Chamber

Jul 16, 2015 | Haley Fu; iNEMI, Prabjit Singh, Levi Campbell, Jing Zhang; IBM Corporation, Wallace Ables; Dell Corporation, Dem Lee, Jeffrey Lee; iST-Integrated Service Technology, Jane Li, Solomon Zhang; Lenovo Limited Corporation, Simon Lee; The Dow Chemical Company.

Qualification of electronic hardware from a corrosion resistance standpoint has traditionally relied on stressing the hardware in a variety of environments. Before the development of tests based on mixed flowing gas (MFG), hardware was typically exposed to temperature-humidity cycling. In the pre-1980s era, component feature sizes were relatively large. Corrosion, while it did occur, did not in general degrade reliability. There were rare instances of the data center environments releasing corrosive gases and corroding hardware. One that got a lot of publicity was the corrosion by sulfur-bearing gases given off by data center carpeting. More often, corrosion was due to corrosive flux residues left on as-manufactured printed circuit boards (PCBs) that led to ion migration induced electrical shorting. Ion migration induced failures also occurred inside the PCBs due to poor laminate quality and moisture trapped in the laminate layers....

PCB Dynamic Coplanarity At Elevated Temperatures

Nov 10, 2011 | John Davignon, Ken Chiavone, Jiahui Pan, James Henzi, David Mendez, Ron Kulterman

With the advent of larger packages and higher densities/pitch the Industry has been concerned with the coplanarity of both the substrate package and the PCB motherboard. The iNEMI PCB Coplanarity WG generated a snapshot in time of the dynamic coplanarity ...
