Boundary Scan Relays Card for Integration into ICT Adapter Systems

03 December 2010 - GOEPEL electronic introduces a special relay card for integration into fixture adapter systems for In-Circuit Testers (ICT). The card is named CION ICT Adapter, and was specifically developed to meet customer requirements for Boundary Scan integration into ICT adapter systems.

The module enables the switching of 32 test channels from the ICT to GOEPEL electronic’s JTAG/Boundary Scan hardware platform SCANFLEX. In quiescent state the ATE channels are connected to the ICT probes, and therefore to the UUT via the relay card. The control signals activation effects the switching to Boundary Scan, what results in a connection between UUT and the SCANFLEX system and the disconnection from the ICT channels.

“The relay card prohibits a collision of both systems’ signals and minimises dynamic effects because of multiple wiring at critical nets”, says Alexander Beck, expert for integration solutions with GOEPEL electronic.

Two LEDs indicate the 5 V supply and the card’s activation state. The module is available in different assembly variants: The “Relay Adapter SL” is equipped with pin contact strips and suits “bird nest” wiring by means of Wire Wrap into adapter systems as well as wiring a 50-pin ribbon cable, as used in DIO plug modules of the SCANFLEX® system.

The “Relay Adapter BU” and “Relay Adapter BU90” are single-sided equipped with a female connector strips. This enables a direct pluggable connection to CION Modules such as FXT96 in both horizontal and vertical direction. The user benefits from the extremely simpler use of CION Modules for ICT and Functional Test.

The relay cards can be utilised with Plug-In Card (PIC) transceivers that provide single-ended signals at the tester interface. Boundary Scan TAP signals are switched with the relay adapter similar to TIC02/SR modules. Additionally, the switching of 32 PIP signals is possible with one card.
