TARGET: thermal accelerated reliability go-no-go environmental testing dynamic board thermal shock using a single liquid fluorocarbon bath

摘要

TARGET, a novel method of accelerated thermal stress for board testing, is described. This method utilizes Fluorinert as the medium for rapid thermal energy transfer. Possible applications include environments for STRIFE testing and board debug. One of the most promising applications is in-line environmental stress screening (ESS). Boards receive a thorough temperature stress screen in the time taken for conventional go-no-go tests. The process is described in detail and analyzed. Data from initial experiments are presented.
