Prototyping
At SHASTA-EMS, we understand that speed, accuracy, and flexibility are critical during the early stages of product development. That’s why we offer fast, reliable prototyping services designed to help engineers and innovators quickly validate designs and accelerate time-to-market.

Our prototyping solutions support a wide range of industries — from RF systems and high-voltage power modules to medical devices and industrial electronics. With a responsive engineering team and in-house manufacturing capabilities, we can produce fully assembled, tested prototypes in as little as 72 hours, depending on part availability.
We work directly with your design files, providing design-for-manufacturability (DFM) feedback to help identify and resolve potential production challenges early. Whether you need a single prototype or a small batch for pilot testing, SHASTA-EMS ensures high-quality builds with close attention to detail.

Our dedicated prototyping process includes:
- Rapid PCB assembly and testing
- Custom cable and harness prototyping
- Box-build and mechanical assembly
- Functional and environmental test screening
- Full traceability and documentation
What makes our service stand out is our ability to bridge the gap between prototyping and production. Once your prototype is validated, we can seamlessly transition your design into low or high-volume manufacturing — without the need to switch suppliers or retrain teams.
Located in San Jose, California, SHASTA-EMS operates out of an 11,000 sq. ft. RoHS-compliant facility, ensuring every prototype is built to meet high industry standards and regulatory compliance.

Whether you’re a startup testing a new concept or an established OEM validating a product upgrade, we provide the speed, support, and technical expertise to bring your ideas to life — fast.
