The Return of the Red Retardant

Abstract: In the 2000s, red phosphorous flame retardants were at the root of widespread and costly failures in electronics products. The most prominent of these failures were in plastic encapsulated microcircuits. These failures were widely reported and painfully experienced. As a result, users of electronic components and finished products came to expect that technical diligence, marketplace forces, and the threat of lawsuits were sufficient to prevent a recurrence. It is therefore surprising that in what appears to be only a few short years after IDMs and OSATs discontinued using red phosphorus flame retardants in semiconductor manufacturing, manufacturers of other types of components began using them. Two or three years after line cord and connector manufacturers went into production with red phosphorus flame retardants, they too started to get field returns.
