Tools and equipment required for parts
replacement
In order to safely remove and replace printed circuit boards modules, generic and
specific tools are required.
You must be equipped with a standard set of tools. This tool set must comprise the
normal tools for electronic and electromechanical tasks. This includes different
screwdriver types, pliers, spanners, a cable stripper, a soldering iron, etc. Each tool
must be provided in various sizes. We recommend that all tools are demagnetized to
protect your equipment.
• Screwdriver (various types and sizes)
• Allen keys (various sizes)
• Cable cutter, knife and/or scissors
• Wire stripper
• Pliers (various types and sizes)
• Spanner (various sizes) (US: Wrench)
• Tweezers
Note
If you need specific consumables, or if special tools and/or test instruments are required,
these are identified in the relevant procedure(s).
Note
Circuit boards and electronic modules are delicate items. They may work year after year
in an advanced product, but then fail due to a small spark of static electricity. For
this reason, it is very important that they are properly handled and protected during
handling. You must be familiar with the applicable handling precautions. Take all
necessary steps to avoid Electrostatic Discharge (ESD).
As a minimum, the following precautions must be taken:
1 For correct and safe handling of printed circuit boards and electronic modules, you
need a suitable working area. The working area must be covered by an approved
conductive service mat that has a resistance of between 50 kΩ and 2 MΩ, and is
connected directly to a reliable earth point via its earthing cord.
2 You - and all other service personnel involved - must wear a wristband in direct
contact with the skin. The wristband must be electrically connected to the service
mat.
3 Printed circuit boards and electronic modules must be placed on the conductive
service mat during installation and maintenance operations.
