Test Flow & Strategy.
START WITH STRATEGY — Before You Touch a Tester
Testing isn’t just about detecting faults, it’s about doing it at the right time, with the right coverage, and at the right cost.
We help clients build smart, scalable test strategies that align with product quality, industry standards, and business goals.
What We Do:
-
Define test methodology based on product complexity
-
Select appropriate fault models (Stuck-at, Transition, IDDQ, etc.)
-
Map test stages: wafer test, package test, burn-in, SLT
-
Set coverage targets based on yield and quality goals
-
Assess cost-of-test vs. defect risk
-
Align test strategy with DFT architecture (if used)
From Strategy to Execution...
Once the strategy is set, it’s time to bring the test program to life
Test Program Development.
BUILD, DEBUG & SUSTAIN
Test Programs at Scale
From first-silicon bring-up to automotive-grade QA, we develop, validate, and maintain test programs across major ATE platforms.
What We Do:
Services We Provide
-
Test plan creation based on a defined flow
-
Test pattern generation and format conversion
-
Full ATE setup (Advantest 93K, Teradyne UltraFLEX, J750, Chroma…)
-
First silicon debug at wafer & final test
-
Program characterization and yield tuning
-
Test time optimization & multi-site enablement
-
Wafer fab transfers and tester conversions
-
AEC-Q100-compliant test release
