3.1. Preliminary
Before any disassembly (except the antenna), the back cover, battery and SIM card must be
removed firstly.
3.2. Precaution
The heart of the handset contains all digital circuit (microprocessor, ASIC, memories, display,
keypad, etc) and the high-frequency transceiver circuit which is protected by the upper and
lower cover.
However, some ESD sensitive area is completely or partially visible (keypad keys, micro-SIM
drive, etc). In order to prevent any risk of ESD damage during disassembly or assembly of
the handset, the operator's wrist should be grounded.
This picture illustrates the connection. The operator wears an electrostatic conduct bracelet
which connected to an anti-static pad. And the pad place on the work surface which
connected to the metal structure workbench, the whole being earthed.
