Test Engineeringdiversifiedsystems' extensive testing capabilities complement our state-of-the-art manufacturing facility, providing a complete EMS solution. Since we offer a full range of test engineering services, we can provide the most economical and comprehensive test strategy for your product. Starting in the product design phase and continuing throughout your product's life cycle, dsi can tailor test strategies and technical support as product requirements change and technological advances transform the functional and physical makeup of your product. Test During the Product Prototype Phase As your product is being developed, we can provide test services that can result in lower costs as the product moves to the production phase. We can perform a comprehensive Design For Testability (DFT) review during the prototype stage and assure that all design considerations for testability have being reviewed and implemented where possible. dsi works with your design engineers to develop test specifications that address the specific subset of design verification/performance requirements that will provide maximum fault detection yet be economical in implementation. |
| For prototype testing, we offer specific functions tailored to our customer's needs and timeline demands. Product verification can be accomplished using functional test methods and incircuit testing (ICT). Traditional ICT testing, while very inclusive, has longer lead times and fixture costs, factors that are not desirable for fast-turn schedules and evolving product designs. . dsi offers an effective ICT alternative--a Flying Probe Tester (FPT), which eliminates fixturing and reduces test development schedules. Since many new products have embedded software/firmware, we can provide In-System-Programming (ISP) for products with flash memories, PLDs or FPGAs. |

Test During the Product
Production Phase For each product that requires testing, a test strategy is defined and implemented to provide the maximum fault coverage at the least possible cost. A strategy may require use of ICT, FPT, functional testing, or ISP. |
| ICT: We implemented Agilent 3073 (HP3073) testers for our incircuit test solution. Capabilities of this implementation include, Boundary Scan (IEEE-1149.1 JTAG) and flash memory device testing. |
| Functional Test: Our test engineers have designed and implemented functional testers using point design systems, commercial off-the-shelf (COTS) equipment (using IEEE-488 and IEEE-1394 interfaces), and VXI. They also have developed test software using LabView/TestStand for ATE applications. |
| FPT: The Flying Probe Test solution is a great ICT alternative for fast-turn or small lot/high mix product groups. Since the FPT is software driven and no fixturing is required, product engineering changes are easily incorporated. |

Test -- Sustaining
Engineering dsi offers a wide variety of services to support continuing manufacturing requirements and specific customer needs. During the production phase of a product, we can provide complete product tracking (by serial number) through each testing phase. Product test results can be archived for record keeping purposes or performance traceability. We continuously make improvements by analyzing field failures and making changes to existing test strategies to make them more comprehensive.. |
