Consolidate **ICT, ISP and Select FCT steps** into a single automated system. Eliminate **five operators, four fixtures, and ~80% of test-cell footprint. Redeploy legacy ICT/ISP systems** on projects that don't require parallel test. **Reduce operating costs** (fixtures + labor) **by \>70%.** Increase throughput with **dual-panel handling + quad-core ICT.** **Two Beds. One Balanced Flow.** **Bed 1:** Executes ICT testing on one panel **Bed 2:** Executes ISP and Select FCT on second panel **Per DUT test time reduced from 25 to 6 seconds** ![4-UP Sequential Mode-2](https://www.checksum.com/hs-fs/hubfs/4-UP%20Sequential%20Mode-2.png?width=400&height=429&name=4-UP%20Sequential%20Mode-2.png)     That **flexibility** — the ability of the **ILS-X2** to **handle two panels sequentially, yet run test steps in parallel** — was a key differentiator in our analysis. It allowed the customer to collapse multiple test stages into a single automated station, sharply reduce handling time and test time, and remove operator intervention relative to current modular architectures. ## Balance. Accelerate. Reduce. By moving select FCT steps to the **panel level** inside the sequential **dual-panel ILS-X2**, testing is accelerated and functional test expense reduced, generating **$450K** savings over five years with a smaller footprint than the previous test cell.  - **Balance -** Dual-paneltwo-bed flow; **SMT- paced** - **Accelerate -** Parallel **ICT/ISP/PFT; 25s**  **→ 6s per-DUT** - **Reduce - 9 → 3 operators; - 1 FT station; fewer fixtures**   ![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 capacity — 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.
