Tools, Equipment and Spares
Torque-drivers
For level-1 and level-2 repairs, excluding SMT repairs of the circuit
boards, the torque-drivers listed in
are required. These are the
only special tools required over and above the standard workshop tools.
For level-1 repairs only the Torx T10 and Torx T20 driver bits are
necessary. The sockets are needed for disassembling and re-assembling
the main-board assembly, which is a level-2 task.
Tools for SMT Repairs
In general only the standard tools for SMT work are required for level-2
repairs of the circuit boards. In addition, a can-removal tool is
recommended but if none is available, a hot-air tool may be used instead.
However, it should be borne in mind that a hot-air tool affords little
control. Even in skilled hands, use of a hot-air tool to remove cans will
result in rapid uncontrolled rises in the temperature of components
under the can being removed as well as under any adjacent cans. The
circuit board might suffer damage as a result.
