PCOLA SOQ Fault Coverage Metrics for Evaluating Escape Rates in Complex Surface Mount Lines
PCOLA SOQ metrics convert raw inspection data into weighted fault coverage, enabling precise calculation of board escape rates and field exposure risk.
Deriving Boundary Scan Diagnostic Coverage for High Density ASIC Arrays
Deriving boundary scan coverage for high-density ASIC arrays requires precise accounting of scannable versus un-scannable nets to prevent costly field escapes.
Boundary Scan Test Coverage Calculations and Fault Diagnostics in High Density Boards
Boundary scan test coverage calculations require explicit PCOLA-SOAMI net weighting to yield verifiable structural fault isolation in HDI board assemblies.
Modeling Escape Rates on High-Speed Differential Serial Nets Using Multi-Regime Coverage Matrix
Multi-regime coverage modeling combines structural, boundary scan, and at-speed functional tests to quantify and suppress differential serial net escapes.
Optimizing Hybrid Probing Access and Boundary Scan Execution Matrices for Complex Non-Scan Logic Clusters
Combining IEEE 1149.1 boundary scan with targeted flying probe access closes logic cluster fault gaps while protecting net integrity and lowering unit test time.
Boundary Scan Coverage and the Faults It Never Reaches
Boundary scan isolates structural opens and shorts on compliant nets, requiring hybrid physical probe testing to catch unmapped passives and dynamic failures.
