Tape Automated Bonding Cards Test Board

The Tape Automated Bonding (TAB) card test system is a mechanical test bench comprising 8 wiring connectors and 2 card connectors with their semiautomatic plugging and extracting system.

The wiring connectors C1 to C8 are used to interface the bench with the testing system which generates the card test stimuli. They are mounted on hinges to ensure easy wiring debug.

The plugging system is composed of 2 mechanical arms M and M' which ensure the card to be correctly and safely plugged into card connector C1 first and then into card connector C2 by acting on arms L and L'. Acting on the two sets of arms in the reverse order will automatically eject the card from the bench. Operating Mode:
1) Connectors 1 and 2 are set in

the "open" position, which means that arms L-L' are in

position A and M-M' in position C.
2) Card is put into pins T-T'.
3) Arms M-M' are moved into D position, which plugs the

left side of the card into connector 1.
4) Arms L-L' are moved into B position, which plugs the

right side of the card by moving the connector 2.
5) Card is tested.
6) Arms L-L' are moved into A position, releasing the card

from connector 2.
7) Arms M-M' are moved into C position, automatically

ejecting the card from the test bench.

Wiring connectors C1 to C8 are standart flat cable connectors, making the TAB card bench interfacing compatible with any kind of testing system.
