  1. Replacing a ZIF Connector Locking Flap, Align the Locking Flap in the Correct Position: step 1, image 1 of 2 Replacing a ZIF Connector Locking Flap, Align the Locking Flap in the Correct Position: step 1, image 2 of 2
    • A Locking flap with the markings "DDF" and "30d" visible on the top is shown in the first photo. It is positioned in the right direction to be replaced.

    • If the locking flap is positioned the wrong way it is easy to turn it around.

  2. Replacing a ZIF Connector Locking Flap, Insert One Side of the Locking Flap: step 2, image 1 of 1
    • Lift the back of the locking flap to position it vertical to the ZIF connector.

    • Insert one side of the flap first. A slight resistance will be felt before it is positioned.

    • You have to be very gentle so as not to break it. The use of tweezers and a magnifying glass is recommended.

    • The gold pins of the connectors must fit inside the flap. The "grid" of the flap is therefore positioned between the gold pins and the silver pins.

  3. Replacing a ZIF Connector Locking Flap, Progressive Insertion of the Locking Flap: step 3, image 1 of 1
    • Gradually insert the flap from right to left.

    • Keep the flap in the vertical position so that it does not come out of its housing.

  4. Replacing a ZIF Connector Locking Flap, Insert the Left Side: step 4, image 1 of 1
    • Finish by inserting the left side in the same way as the right side.

    • This is a delicate operation. On occasion the flap comes out of the housing. If that happens, starting over is the best option.

    • Finish by pushing the flap as far as possible inside the connector.

  5. Replacing a ZIF Connector Locking Flap, Functional Check: step 5, image 1 of 2 Replacing a ZIF Connector Locking Flap, Functional Check: step 5, image 2 of 2
    • Verify that the flap pivots correctly without coming off its axis.

Conclusion

You can now resume reassembly where you left off.
