Lessons Learned - Solder Defects Reduction by Training/certification of Technicians
Year: 1989
Abstract: Description of Driving Event:
Following the shuttle mission STS-34, it was determined that a vent door actuator operated on two of the three electrical phases. The vent door actuator was replaced. During the failure analysis, a defective solder joint was found on a lead connection to a printed circuit board, analysis indicated the solder was contaminated with room temperature vulcanizer (RTV) silicone potting compound. Records revealed that this defect occurred prior to the requirement to train and certify the solder technicians to the aerospace quality standard DOD-STD-2000.
