Watch the prevention video on physical damage to the product because of external causes to see how this type of damage can occur and what you can do to prevent it.

Physical damage to a motherboard or processor is caused by improper handling or integration of the board into the system. This document describes common causes of physical damage and recommended preventative actions.

Screwdriver damage
Screwdrivers used during integration can slip and strike motherboard components causing damage leading to system failure.

Examples of damage from screwdrivers

Damage caused from screwdrivers or other tools:

  • Around screw holes
    • Often due to screwdriver slipping around motherboard mounting hole
  • Around processor heat sink assembly
    • Often caused by a tool used to attach heat sink assembly
  • back to topback to top

    Trace damage
    A damaged or cut trace on a motherboard can cause the system to fail.

    Example of a cut trace

    Damage to traces can occur around mounting holes and around heat sink assemblies. They can also occur on the secondary side (back) of the motherboard.

    Connectors and sockets
    Connectors and sockets on the motherboard can be damaged during shipping or integration.

    • Processor socket damage
    • Memory slot damage
    • PCI, PCI Express*, AGP and other slot connector damage
    • Pin damage on IDE connector, floppy connectors or other onboard headers
    Examples of processor socket damage

    Recommended actions to reduce or prevent damage
    Preventing screwdriver damage:

    • Use a magnetized driver tip that matches the screw head size.
    • Make sure there is good lighting so the screw holes are clearly visible when integrating the board in the chassis.
    Preventing socket or connector damage:
    • Make sure the components are positioned and aligned properly prior to insertion.
    • Do not force components into the sockets.
    • Make sure the processor socket lever is fully open prior to insertion.
    Inspecting for physical damage:
    • Experience shows that spending at least 30 seconds inspecting the board helps detect as much as 90% of the mechanically induced damage.
    • Use a 2X magnifying lamp.
    • Follow a consistent inspection pattern, such as up and down, left to right each time you inspect a board.
    • Document common defect areas to help you identify where problems repeatedly occur.

    Develop proper handling guidelines
    Post simple handling guidelines for training and reinforcing proper handling techniques. Examples are shown below:

    Correct way to hold a board

    Do not hold a board by the heatsink

    Do not hold a board by the connectors (note thumb placement in image)

    Do not apply pressure on or touch the processor socket


    Do not apply pressure on the processor socket cover

    Do not flex the board during integration or removal

    Do not hold by the corners

    Do not handle or touch capacitors on the board

    Place boards in ESD bags. Incorrect and correct ways to store boards are shown in this image.
