JTAG / boundary scan tools by GOEPEL electronics
What is JTAG / boundary scan?
Overview of JTAG / boundary scan tools offered by GOEPEL
Questions to consider when selecting JTAG / boundary scan tools and services
Why should you care about JTAG / boundary scan ?
Here are some of the reasons why:
- Regain test access (think of test access problems with BGA, multi-layer PCBs, internal-only signal traces [no vias / test points])
- Reduce cost of test (reuse tests throughout the product life cycle, no or simplified fixtures, less expensive equipment, ...)
- Debug prototypes, detect defects and diagnose faults down to pin level; reduce time-to-market
- Precise diagnostics and fast test execution in manufacturing tests, improve yield and productivity
- No / reduced physical stress (probing), less risk for damage of the unit under test
- In-system configuration/programming for CPLD, Flash, serial EEPROM, on-chip memory [MCU, MPU] (just-in-time programming, no inventory management issues and costs related to programmed devices)
- Simplify test strategy and reduce cost by combining test methodologies (BScan/VarioTAP-PET + ICT/FPT/FT/AOI)
- Reduce or eliminate NDF (No Defect Found) issues with in-field, in-system test and error logging, reduce cost of repair / warranty returns
=> lower cost, increased quality
