Edge Circuit Technology's CTO and Cofounder is a testing and testability design expert with over 20 years of industry experience, and has consulted numerous electronic manufacturing and OEM
companies in Southern California.
Testing is generally implemented in three linear phases: component, board level and functional. Aside from verifying the integrity and function of every unit, a largely
forgotten benefit of testing is diagnostic data gathering. With this vital data, defective units can be restored into operational, deliverable products.
Furthermore, the complexity and cost for testing and diagnostic analysis escalates exponentially at every next step which requires increasingly sophisticated, refined
testing parameters and procedures. Therefore, it is prudent and advantageous to identify, minimize and resolve problems early.
ECT offers:
Complimentary Testability Design Review
As part of our commitment to deliver value-added services, ECT offers our customers complimentary testability design review and advisory on approaches to achieve
optimal efficiency. Our customers have been enjoying this valueable service and please contact us for your free Testability Evaluation. Depending on the scope of work, our
Testability Evaluation may include:
- Design Review
- Reliability Specifications
- Manufacturability Design
- Production Engineering
- Boundary Scan
ECT believes that a disciplined manufacturing process,
combined with skilled technicians, and MDA/ICT component testing
will significantly improve and enhance yield performance. It is imperative to
include test point to every net in every circuitry and they must be
accessible after assembly. With such test points and built-in
test programming, fault isolation will be swift and accurate, but
testability must be considered during product design stage for
efficient test and diagnostic analysis.
Such functions will reduce
bottleneck, cycle time and hence production costs. With this recaptured
productivity, our customers will increase sales, achieve time-to-market
advantage and enhance brand equity and profitability. The following list highlights
some of the critical issues to consider:
Testing cost reduction:
- Fixture and Programming costs
- Overall testing cost
- Diagnostic analysis and data gathering cost
- Test equipment life preservation
Technical solutions for testability design:
- Initialization problem
- Noise reduction or timing problem during testing
- Access control for devices within feedback loop circuit
- Oscillators and clocks generated problem correction for ICT testing
- Isolation for ICT testing
- Addition on board and Path testing (built-in test)
- Input and output bench testing improvement
- Programmable device controllability settings
- Boundary scan testing
