Test Interface Solutions Using Generic CB30 and CB60 Boards

The 128-point counterpart of the CB8/H. Mount as many connectors as its 128 test points allow, using pigtails for any that don't fit on the board.

The CB60 looks similar to the CB30, but is designed to operate at higher voltage.

As long as the connectors under test are suitably voltage-rated, the board configurations you see below may be realized with either the CB30 or CB60.

Clearly, high voltage testing requires an HVX-series tester.

1 - M3Z (768 TPs) continuity tester fitted with stock, interchangeable, plug and play, quick-connect CB30D interface fixtures for testing cables terminated with LFH200 connectors.

Each CB30D daughter board is mounted to a CB30.

The test unit shown comprises a control module and five expansion modules and can be further expanded to a total of 2560 test points.

The auto ID connector graphic for the LFH200 connectors appears below.

2 - This stock, auto-detectable, CB30G board set for Cannon's ZIF DL5-260 connector requires the CB30 motherboard set and a 640 TP system. Low voltage continuity tester shown.

3 - We designed the CB30B daughter board shown here to mount on the CB30 board to interface the Cannon DL-156 ZIF (zero insertion force) connectors. This 384-point CableEye system provides three 64-pin banks for each connector. The CB30 board can also be configured for Cannon DL-96 and DL-60 connectors.

The auto ID connector graphic for the DL-156 appears below.

4 - This CB30 board secures an adapter cable for a 128-pin high-density circular connector. Nylon lacing and wire-ties are used to route and secure the wiring leading to the terminal pads.

5 - We mounted two independent circular connectors on this CB30. Because the customer wanted both connectors on the same board and more than 64 test points were required to do this, we used a CB30 (128 points maximum) instead of a CB8 (64 points maximum). The board is wired from the back, and if you look carefully, you can see some of the wiring through the unused slots.

The upward-facing connector in the front takes a 64-conductor flat cable that connects to an expansion module to obtain the additional test points needed.

6 - In this application, four adapter cables connect to a single CB30 board. The upward-facing connector seen in the previous image is mounted on this CB30 in a downward direction on the back of the board to make room for the adapter cables. Padding is added to the front edge of the board to prevent chafing as the adapter cables are moved around.

7 - This unusual connector required more than 128 test points, so we used all 128 points from a CB30, and added a single 64-pin AMPMODU connector to pick up the remaining points and route them to an available bank on the tester.
