and Wave soldering. Typical profiles are shown on the right.
The recommended solder for the MLA Automotive Series
Wave soldering is the most strenuous of the processes.
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
During the soldering process, preheating to within 100
degrees of the solder's peak temperature is essential to
minimize thermal shock.
