Solder Paste & SPI — Solder paste printing and SPI establish the first controlled assembly checkpoint.
SMT Placement — Automated placement equipment positions components for repeatable assembly.
Reflow & AOI — Reflow soldering is followed by automated optical inspection for process verification.
Functional Test — In-circuit and functional test options are aligned with the product requirement.
Final Assembly — Final assembly, inspection and protected packaging prepare the build for delivery.
