These test points are only used for module manufacturing and testing. They are not for customer’s
application.
For customer convenience, SIMCom provides a typical example for a commonly used soldering profile. In
final board assembly, the typical solder reflow profile will be determined by the largest component on the
board, as well as the type of solder/flux used and PCB stack-up. Therefore the soldering profile shown
below is only a generic recommendation and should be adjusted to the specific application and
manufacturing constraints.
