NLX Motherboard Form Factor: Test & Rework Opportunities

With the NLX form factor, you can easily insert and remove motherboards from a completed chassis without disturbing other components. Easy access to motherboard components allows convenient resolution of potential memory and processor failures. Below are some tips for you to keep in mind.

• Visual Inspection
  • During your initial production of NLX systems, you may want to make a close visual check for the following:
    • Damage to connectors and sockets.
    • The fit and placement of the I/O shield.
    • Complete insertion of motherboard into riser connector.

    • Correct wire connections.

• NLX Rework Considerations

• Because NLX motherboards are easily removable, chassis verification using a "gold" motherboard is greatly simplified.
• Before removing the motherboard, remove the external cables and the AGP card.
  • There should be no internal cabling to the motherboard.
• Always ensure power is off and system is unplugged before removing or inserting motherboards.
  • No "hot swap".
• Remove motherboard using the insertion/removal latch.
• The latch will aid disengagement from the riser card.
• Additional tooling may be necessary to fully remove the card.
• Pulling on the processor or AGP slot connector is not recommended.
