4.2 Anti-static Precautions
WARNING:
Failure to take ESD precautions during the maintenance of the AFL4-
W07-EHL may result in permanent damage to the AFL4-W07-EHL and
severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the AFL4-W07-EHL. Dry climates are especially susceptible to ESD. It is
therefore critical that whenever the AFL4-W07-EHL is accessed internally, or any other
electrical component is handled, the following anti-static precautions are strictly adhered
to.
◼
Wear an anti-static wristband: Wearing a simple anti-static wristband can
help to prevent ESD from damaging the board.
◼
Self-grounding: Before handling the board touch any grounded conducting
material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.
◼
Use an anti-static pad: When configuring the AFL4-W07-EHL, place it on
an anti-static pad. This reduces the possibility of ESD damaging the AFL4-
W07-EHL.
◼
Only handle the edges of the PCB : - When handling the PCB, hold the
PCB by the edges.
