Disassembly of CF62 Leopard
ESD concept; the internal circuits will be more susceptible to ESD because of the use of
exchangeable housing. The construction of the internal block must be/is designed, in the best
possible way, to protect the circuit against sparks.
The keypad and the metal dome must be completely closed to prevent any occurrence of an ESD
disruptive discharge.
The SIM contacts may be open, thus reachable for ESD contact discharge. This could lead to
damage or destruction of the IC pins.
It is a requirement for the service personnel to observe ESD protection rules while performing
servicing the CF62.
