GOPEL Combines JTAG/Boundary Scan and Optical Inspection

News Release from: GOEPEL electronic
31 July 2009

GOPEL electronic is offering a cost-effective hybrid JTAG/Boundary Scan and optical test system. Simple optical inspection tasks of LEDs, displays or OCR are executed by the TOM (Teachable Optical Measurement) system whilst Boundary Scan controls the board. That means users are provided with a one-stop shop of electric and optical testing, both developed and produced by GOEPEL electronic.

In addition to the high test coverage, the advantage of this combination is the automation of tradition manual visual inspection, e.g. LEDs and displays verification. By omitting an operator the test speed significantly increases and removes human error. Furthermore, characteristics can be evaluated that are not visible to the naked eye (brightness, contrast). Last but not least, the combination of electric and optical tests enables the detection of critical faults also in hidden areas, e.g. shorts or open pins.

A camera is installed above the board under test for optical inspection. The test results are analysed by the TOM software and sent to the JTAG/Boundary Scan software suite SYSTEM CASCON™. Because both software programs are compatible all test results of the Boundary Scan and optical inspection are displayed in SYSTEM CASCON™. That means users see all results integrated in one window or monitor.

Using JTAG/Boundary Scan, test, programming, verification, debug and emulation tasks can be executed. GOEPEL electronic’s SYSTEM CASCON™ is a professional JTAG/Boundary Scan development environment with currently 40 completely integrated ISP, test and debug tools, supporting IEEE1149.1, IEEE1149.4, IEEE1149.6, IEEE1532, and JESD71 as well as mixed signal operations and VarioTAP® for emulation test.
