GÖPEL electronic and SPEA have developed a boundary scan option for the Flying Probe Tester (FPT) 4040 within the scope of an OEM agreement. The solution is based upon the integration of the Cascon Galaxy software and Scanflex hardware into the flexible Flying Probe test system, involving the FPT probes to extended the Boundary Scan tests.

“Combining the capabilities of SPEA Flying Prober with GÖPEL electronic JTAG/Boundary Scan solutions offers significantly higher test throughput due to optimised use of tester resources, applying the most efficient test technology for specific board structures,” said Bettina Richter, marketing and international sales manager for GÖPEL. “The possibility to reuse existing Boundary Scan applications for testing and programming Flash components or PLD, makes this solution very attractive due to a short ROI for CMs.”

The integration is based on the Scanflex USB/LAN controller models SFX/USL1149-x with TCK frequencies of 20MHz (A type) or 50MHz (B type), respectively. The JTAG test bus connection to the Unit Under Test is realized with a Scanflex transceiver model SFX-TAP4/CR, which provides four parallel TAPs with interposing relays and up to eight programmable interface parameters for the optimal adaptation to the UUT, connected to the standard interface of the Flying Prober. The distance between TAP-Transceiver with CION interface and UUT can be up to 1.5 m., without the need for additional signal conditioning. The flying probes extend boundary scan test coverage and are controlled by the native pin electronics of the 4040, requiring no extra driver/sensor circuitry.

The software development and execution environment has been integrated into the Flying Prober's operating system Leonardo via the CAPI interface. The test vectors' link to the Flying Probes is managed through Hyscan, which enables the synchronisation of serial JTAG/Boundary Scan test vectors with parallel test vectors. The parallel vectors are linked to the physical I/O interface at run time, providing tester hardware independence. The flying probes make up this physical I/O interface.

The automated or manual generation of test vectors, debugging and fault diagnostic is done with JTAG/Boundary Scan tools. Each Flying Probe acts as an additional bidirectional Boundary Scan pin at the contacted net. Data handling is done automatically.
