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.

In October, Universal Instruments Corporation’s Advanced Process Lab (APL) held its third Advanced Research in Electronics Assembly (AREA) Consortium meeting of 2012 at Binghamton University’s Innovative Technologies Complex in Vestal, N.Y. The 25-member consortium, organized by Universal, helps member organizations identify and develop new and emerging technologies, generating applicable knowledge for specific product development and manufacturing processes.
Incoloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in all

All, We know that incomplete immersion silver could potentially lead this creeping corrosion. Is there any way to check bare PCB for incomplete immersion silver coverage, especially on the via hole area? Thanks, Sean.

Hi All, I have few questions about creeping corrosion that potentially happen on lead free immersion silver PCB as below: 1) What test that we can conducted to verify whether the failure we seen is due to creeping corrosion? 2) I heard that lead fr
