1. Thales strongly recommends to provide test points for certain signal lines to and from the module while
developing SMT applications – for debug, test and/or trace purposes during the manufacturing process.
In this way it is possible to detect soldering (and other) problems. Please refer to [5] and [6] for more in-
formation on test points and how to implement them. The signal lines for which test points should be pro-
vided for are marked as “Test point recommended“ in the above table.
