30 Years of Bringing Bad News, One Board At A Time Continued from page 58
written off and placed in a “bonepile.” These defec- tive PCBAs represent lost revenue, and a chal- lenge to test and repair. OEMs often invest time and resources in troubleshooting these PCBAs, with little return on investment. As an alternative, Datest offers test resources and expertise that can represent a more practical approach to an OEM. By helping to rehabilitate the bonepile, this helps to recover revenues for customers. The concept of rehabilitating the bonepile is
fairly straightforward: customers bring their data, available documentation, and previously written- off failures. Datest then uses its test engineering resources and measurement platforms to bring these failed boards “back to life.” The firm makes full use of its suite of integrated testing resources to trou- bleshoot, rework, and restore PCBAs to operational status per the require- ments of a customer’s functional or system test, or even in the field under operating conditions. This involves directly reworking the boards or showing customers where to rework them if a customer prefers to make these modifications within their own facility. Communications is a key to achieving success in this “rehabilitation” process, and Datest works closely with a customer to communicate what is defined as a “good” board after it has been reworked. The rehabilitation service is offered at a fraction of the original manufactured cost and is suitable for reverse logistics, warranty repair, and returns management programs. The same hardware and soft-
ware resources used for production board testing are also used at Datest to aid troubleshooting, fault diagno- sis, board repair, and board recovery. For these purposes, testing is often performed with the flying probe sys- tem or using x-ray inspection or boundary-scan/JTAG testing. In each case, the goal is to develop an efficient test solution that is both cost-effective and delivers significant value (i.e., has a high recovery rate) at zero-risk to customers. By analyzing the fail- ures and using its full range of testing solutions platforms and engineering know-how, it is possible to rehabili- tate many of the bad boards, restore “lost” revenue and contribute to a greener world. This is an economical and intuitive answer to a perennial issue that delivers significant mone- tary and environmental benefits in a world where diminished resources have become a fact of life.

Page 61 It’s important to understand the importance
of adapting to industry needs and providing the most comprehensive value-added services possible. What started as a small EMS has grown into a thriving, multifaceted services provider, leverag- ing the latest measurement capabilities to help customers. The company uses its technologies and experience to present cost-effective, environmen- tally friendly solutions to the challenge of failure analysis. Failure is indeed an option, if it is possi- ble to learn from it and find practical solutions. Contact: Datest, 47810 Westinghouse Dr.,
