Systems Integration
From Circuit Board to Finished Product.
PPSI goes beyond PCB assembly to deliver fully integrated systems ready for deployment. From box builds and enclosure assembly to final test and packaging, we handle the complete integration process, so you receive a finished product, not a pile of parts.
Integration Services
Box Build Assembly
Complete mechanical and electronic assembly including PCBA installation, enclosure assembly, thermal management, mounting hardware, and final closeout.
Electromechanical Assembly
Integration of motors, fans, switches, displays, power supplies, and other mechanical components with your electronic assemblies.
Cable & Harness Integration
Custom cable assemblies and wire harnesses routed and installed within your enclosure. Built in-house to IPC/WHMA-A-620 standards.
Conformal Coating & Potting
Environmental protection for assemblies exposed to moisture, dust, vibration, or temperature extremes. Acrylic, urethane, and silicone coatings applied in-house. Potting and encapsulation services available with 3D-printed tooling for fast turnaround on custom fixtures and masking.
