Baseband Troubleshooting Instructions CCS Technical Documentation General instructions Most semiconductors are static discharge sensitive! ESD protection must be taken care of during repair (ground straps and ESD soldering irons). HAGAR, PA, UEM, UPP, and Flash are moisture sensitive and must be pre-baked prior to soldering, if they have been out of their vacuum package longer than the specified time. • Connect test jig to computer with DAU-9S cable or to FPS-8 Flash Prommer with AXS-4 serial cable.
