Plexus In-Circuit Test Development Process

Plexus In-Circuit Test Development Process

Plexus has pioneered a revolutionary board level test technique that accurately defines and measures the degree of test coverage to detect shorts, opens, and component placement.

In-Circuit Test Fixture Plexus Test Coverage Commitment
  • 100 % Shorts
  • 95 % Opens
  • 95 % Component Placement

Plexus translates the commitments set forth in our proposals with a design process to optimize the test method per component based on physical accessibility, electrical DFT constraints, and device compatibility.

Test Method Specification
  • Program & Fixture Design
  • Fixture Fabrication & Inspection
  • Design Integration & Repeatability

To ensure the test coverage and product specific requirements defined in the Design Plan are satisfied, Plexus verifies, validates, and documents the test results prior to the manufacturing installation.

Design Verification and Validation
  • Verifies the design was implemented per the plan
  • Validates the performance goals - Shorts, Opens, Component Placement
  • Documents the design and results - Test Coverage Reports

To manufacture product on time for our customers, Plexus ICT hardware and software are developed with a team of engineers dedicated to consistent on time delivery.

Manufacturing Installation & Support
