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. ![SE Asia Manufacturing map 48-Up PCB](https://www.checksum.com/hs-fs/hubfs/SE%20Asia%20Manufacturing%20map%2048-Up%20PCB.png?width=1872&height=792&name=SE%20Asia%20Manufacturing%20map%2048-Up%20PCB.png) ## 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: ISP** **Programming** + **PFT** high-speed functional test measurements. This keeps both beds loaded and **outpaces SMT** in a single, integrated fixture. ![Results Infographic SE Asia 48-UP](https://www.checksum.com/hs-fs/hubfs/Results%20Infographic%20SE%20Asia%2048-UP.png?width=800&height=448&name=Results%20Infographic%20SE%20Asia%2048-UP.png) ### **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 ![Process Comparison A14](https://www.checksum.com/hs-fs/hubfs/Process%20Comparison%20A14.png?width=800&height=600&name=Process%20Comparison%20A14.png) ![Process Comparison B16](https://www.checksum.com/hs-fs/hubfs/Process%20Comparison%20B16.png?width=800&height=600&name=Process%20Comparison%20B16.png) ## 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**.   ![ILS-X2 Conveyors 12-Up PCB Transp C](https://www.checksum.com/hs-fs/hubfs/ILS-X2%20Conveyors%2012-Up%20PCB%20Transp%20C.png?width=1920&height=1348&name=ILS-X2%20Conveyors%2012-Up%20PCB%20Transp%20C.png) **Results:** Substantial cost reduction, enhanced quality, freed-up floor space, and higher throughput — uniquely enabled by CheckSum’s **parallel test + parallel handling** architecture. ![Project Analysis PCB Discussion C-2](https://www.checksum.com/hs-fs/hubfs/Project%20Analysis%20PCB%20Discussion%20C-2.png?width=1101&height=720&name=Project%20Analysis%20PCB%20Discussion%20C-2.png) ### Let's Talk About Your Project -- Request Your Free Analysis Now.
