Handling boards

All the boards described in the following are fitted, among other things, with
large-scale integrated circuits. Voltage impulses caused by static charging
from people or objects can easily destroy the circuits.
When handling boards, ensure that the electronics cannot be damaged by
static charging or discharging.
Place the printer on an earthed underlay before opening it.
Earth your body with an ESD protective armband or by using another
suitable means. If suitable ESD protection is not available, touch an
earthed object, e.g. a radiator, before touching a board.
Only place boards on an earthed underlay.
The conductor lines on modern multilayer boards are very thin. Bending the
boards can therefore easily break the conductor lines.
Avoid bending the boards.
Avoid using excessive force when removing and installing the boards.
