OUR CAPABILITIES Custom Cable Assemblies At Circuit Assembly, our custom cable assemblies are engineered to solve the unique challenges of each application, whether it’s electrical performance, environmental protection, signal integrity, or mechanical stress relief. Our Capabilities Span: ▪ Overmolded Cable Assemblies in special sizes or shapes to fit with customers application. Angled molds for special routing. Chassis mounted strain reliefs. Custom mold for application fitment. ▪ High-speed data and hybrid signal/power cables for performance, compact layouts, and reduced cable count. ▪ Custom breakouts, lengths, and connector configurationsto match your system’s mechanical and electrical requirements. ▪ Shielded cables for signal integrity in high-interference environments.

7. OUR CAPABILITIES Wire Harnesses Our wire harnesses are custom-built to organize and protect electrical systems, streamlining installation, improving durability, and reducing risk of failure. We offer: ▪ Custom routing and bundling to simplify integration into tight or complex enclosures. ▪ Connector-to-connector harnesses with exact lengths, labels, and terminal types. ▪ Protective sleeving and jacketing for abrasion resistance, heat shielding, and flexibility. ▪ Pre-tested harnesses with continuity and functionality checks before shipment.

8. OUR CAPABILITIES PCBA (Printed Circuit Board Assembly) Circuit Assembly provides full-service PCBA offerings, from sourcing and assembly to inspection and testing. Our facilities handle both surface mount (SMT) and through-hole technologies, supporting everything from quick-turn prototypes to full-scale production runs. We Specialize In: ▪ Component Sourcing & Procurement: Leveraging a global supply chain to secure reliable, cost-effective components. ▪ Mid to High Volume Capability: Multiple global locations to satisfy all time and volume requirements. Our smaller volume and quick-turn projects are handled in California, while our higher volume projects are cost effectively manufactured in China. ▪ Inspection & Testing: Comprehensive quality control, including AOI (automated optical inspection), functional testing, and X-ray for components. ▪ Conformal Coating & Encapsulation: For added protection in harsh environments.

9. OUR CAPABILITIES Box Builds Circuit Assembly offers comprehensive box build assembly services, providing end-to-end solutions for integrating electronic and mechanical components into complete systems. Our Capabilities Include: Enclosure Integration: Assembly of custom enclosures housing PCBAs, wiring, and other components. ▪ Cable and Harness Installation: Precise routing and installation of cables and wire harnesses. ▪ Mechanical Assembly: Integration of mechanical parts, including switches, displays, and connectors. ▪ Programming: Our technical team can support programming of firmware/software on your build as ▪ needed as part of the assembly process. Testing and Quality Assurance: Rigorous functional testing to ensure product reliability and ▪ performance based on customers individual requirements. Testing equipment can be custom built for your build or consigned to our team during the manufacturing process. Packaging and Labeling: Final product packaging, labeling, and documentation ready for distribution. ▪

10. OUR CAPABILITIES Prototype & EOL (End-Of-Life) At Circuit Assembly, we support your product’s full lifecycle from early-stage prototypes to navigating EOL transitions.
