G50 Disassembly & Assembly G50 Disassembly & Assembly Tool: Tweezers Screwdriver (T5) Torque (M1.6*4.0): 0.5 ± 0.01 Kgf/cm Caution: The equipment described in this part contains electrostatic devices (ESDs). Damage can occur to these devices as well as components if the appropriate handling procedure is not adhered to. The operation area should be equipped with well protection to these components and devices.
Special Notice 1.There is a direct relationship between ESD performance and the shielding cover. Also, It may cause Insert SIM Card problem because of the Shield-SIM-Holder being out of shape. Replace a new one if any shielding cover is deformed during disassembly. 2. G50 is manufactured under lead-free process. Alloy: 95.5 Sn/4Ag/4Cu Melting Point: 217
