(2) the modules should be handled in the same manner as ordinary semiconductor devices to prevent the electro - static damages. for safe keeping and carr ying, the modules should be packaged with esd proof material. to assemble the modules on pcb, the workbench, the soldering iron and the human body should be grounded. (3) please pay special attention to the atmosphere condition because the dew on the module ma y cause some electrical damages. (4) under such a strong vibration environment as in automobile, the performance and reliability are not guaranteed.
