Tier-One Global Automotive Supplier Test Project Summary
For a high-volume ultrasonic sensor program built in dense 48-up panels, a global tier-one automotive supplier in Southeast Asia needed to shorten cycle timetokeep pace with SMT and improve test operation efficiency to remain competitive. The incumbent test process separated ICT, programming, and functional test (FT) -- requiring significant labor, fixtures, and floor space. Even with dual-core ICT, test time ran slightly longer than SMT takt time, and they relied on mini-panel FT (4-up) across three stations just to keep up.
CheckSum Parallel Test Process Analysis - What We Unlocked
Bring full-panel FCT into the cell. Balance the flow.
For the customer’s 48-up ultrasonic sensor program, our analysis showed that a single ILS-X2 -- running sequential dual-panel handling with Quad-Core ICT -- can execute a balanced two-bed process.
Bed A: ICT on one 48-up panel.
Bed B: ISPProgramming + PFT high-speed functional test measurements.
This keeps both beds loaded and outpaces SMT in a single, integrated fixture.
Why it Mattered:
Separate FT Operations Eliminated— ICT + programming + all FT executed in one ILS-X2 panel-level cell.
Operators Down 100%—12 → 0 dedicated operators.
Systems Down 80%—5 → 1 tester; fewer fixtures and a smaller footprint.
Savings & Capacity — $300K Year-1; >$825K/5-year, with 12M sensors tested in <1 shift
Current Process vs CheckSum
Synchronize. Consolidate. Accelerate.
Synchronize — Dual-panel, sequential two-bed flow keeps both beds loaded and matches SMT Takt Time.
Consolidate — ICT + ISP + all FT in a single cell; no standalone FT stations; smaller footprint.
Accelerate — Full-panel parallel test outpaces SMT, compressing cycle time with Quad-Core ICT + MultiWriter ISP + PFT.
Results:
Substantial cost reduction, enhanced quality, freed-up floor space, and higher throughput — uniquely enabled by CheckSum’s parallel test + parallel handling architecture.
