Teradyne Inc. (Boston, MA) announced that Harman Music Group (Salt Lake City, UT), a manufacturer of audio products, has selected a Teradyne Assembly Test Division test system as their transmission x-ray tester of choice. Harman Music Group has chosen to use the Teradyne XStation HS automatic x-ray inspection system exclusively for all manufacturing test in their Sandy, UT, facility.

Harman began using the system two years ago. Fast test times, averaging 20-30 seconds, enable the test system to keep pace with the manufacturing line which runs two shifts, seven days a week. Using only automated optical inspection (AOI) for component polarityand value checking up front and functional test before shipment, Harman relies solely on Teradyne's system to verify the integrity of their manufacturing process.

Harman was selected to beta test the new Xframe product, an integrated software development environment for the inspection system. The PC-based software program allows all programming to be performed off-line. The software provides flexibility by giving the user the ability to set thresholds rather than hard-coding them into the software. It deploys a new graphical user interface (GUI) and ensures data quality using an industry-standard Oracle database.

According to Paul Marconi, director of manufacturing for Harman, "We test 10,000 boards a month and are constantly seeking process improvements—the x-ray product is a major contributor to our success. Now, we will be able to quickly develop new test programs off-line whenever we bring new products into manufacturing."

The software provides fast program development time via built-in, GUI-driven inspection wizards based on the Red Hat Linux operating system. Employing D2B and Alchemist for CAD preparation, the software automatically generates measurement windows and thresholds. It uses built-in machine simulator software so that users can perform all inspection program debugging off-line, instead of on the system used in production. A centralized Oracle database is used to store and manage program data, ensuring consistent and fault-free data.

Harman Music Group designs, manufactures and markets signal-processing equipment for professional musicians, recording studios and sound system engineers. It markets its products under the brand names dbx, DigiTech, DOD and Lexicon Pro. The company is a subsidiary of Harman International Industries.
