OUR SOLUTIONS

From rapid PCBA prototyping and One-Time Production PCBA assembly to repairs, upgrades, and short-run production, we provide expert solutions to keep your projects moving forward. Whether you're bridging the gap between old and new products, validating a design, or scaling production, our team ensures precision, efficiency, and fast turnaround times. Let’s build something great together.

PCBA PROTOTYPING

Prototypes are what we do every day. Our goal is to provide you with quality products that will validate your designs in as short a period of time as possible. Our staff can source all the components for your design, or provide labor only builds if you have all the components, or a combination of both. Let us know what you need.

One-time production PCB ASSEMBLY

Are you looking for a one-time build to bridge the gap between old and new products? Or perhaps support for legacy products? Ninja can provide you with fast turn options tailored to your needs that will help minimize your inventory requirements and still service your customers efficiently.

REPAIRS, UPGRADES, REPLACEMENTS

If you need assistance with a product already assembled, Ninja can help. Component upgrade or replacement, modifications, repairs, Ninja personnel have the skills and experience and equipment to help bring your existing product to the desired configuration.

SHORT-RUN PRODUCTION

Do you need to bring your product to market but your electronics manufacturer can't ramp up fast enough? Ninja can meet your short-run needs with fast turnaround of quantities to fit your demand.
