4.1 Inserting a Device

To program a chip, insert the chip into the appropriate socket.

Whenever handling chips, always be sure to follow safe handling procedures to ensure that the chips are not damaged.

All sockets are zero insertion force sockets and work on the same principle.

To insert a chip:

1. Press down on the top of the socket to raise the contact pins.

2. While pressing down on the socket, carefully place the chip into the socket and make sure that the orientation of the chip is correct (pin 1 should always be in the top left corner).

3. Once the chip is in place, release the top of the socket to allow the contact pins to drop and hold the chip in place.

At this point, the chip should be held securely in place. Please make sure that all the contact pins have made contact with the correct pins on the chip.

4.2 Removing a Device

When removing the chip, we recommend using a vacuum pickup tool to prevent damage to the chip and its pins.

To remove a chip:

1. Press down on the top of the socket to raise the contact pins.

2. Carefully remove the chip using a vacuum pickup tool or equivalent tool.

3. Release the top of the socket.
