All ICs and many other semi-conductors are

susceptible to electrostatic discharges (ESD).

Careless handling during repair can reduce life

drastically.

When repairing, make sure that you are

connected with the same potential as the mass

of the set via a wrist wrap with resistance.

Keep components and tools also at this

potential.
