Components Packaged with Phosphorus-Containing Molding Compound

Posting Date: May 8, 2002

Some companies have experienced failure in components due to internal shorting. It has been speculated that the root-cause may be due to phosphorus being used a substitute fire retardant in replacement of bromide.   CALCE learned of this mechanism from industry sources who performed their own analysis. We have not determined whether this is an isolated issue or whether a broader problem exists. As a result, any activities in response to this information should be independently verified.

The purpose of this information is to keep subscribers to the CALCE newsletter informed on identifying new failure mechanisms, improving root cause analysis, and developing corrective actions. Should additional information become available, we will update this notice on our web site.
