To avoid the possibility of generating stresses due to thermal shock, a preheat stage in the soldering process is recommended, and the peak temperature of the solder process should be rigidly controlled. When using a reflow process, care should be taken to ensure that the MLA Automotive Series chip is not subjected to a thermal gradient steeper than 4 degrees QFSTFDPOE UIFJEFBMHSBEJFOUCFJOHEFHSFFTQFSTFDPOE During the soldering process, preheating to within 100 degrees of the solder's peak temperature is essential to minimize thermal shock. 0ODFUIFTPMEFSJOHQSPDFTTIBTCFFODPNQMFUFE JUJT still necessary to ensure that any further thermal shocks BSFBWPJEFE0OFQPTTJCMFDBVTFPGUIFSNBMTIPDLJTIPU printed circuit boards being removed from the solder process and subjected to cleaning solvents at room temperature.
