We Are Different

Traditional manufacturers often require high minimum order quantities (MOQs) and long lead times, which can hinder your ability to iterate on designs, test the market, and scale production quickly. Additionally, managing complex supply chains and ensuring top-notch quality can be a challenge, and finding affordable turnkey services may feel impossible.

High Mix, Low-Volume Orders

Order from 1 to higher quantities of CCAs. We eliminate high upfront costs, minimum order quantity requirements, and unnecessary inventory.

DFM Reviews To Drive Success

We offer design-for-manufacturability (DFM) reviews that optimize your CCAs and PCBAs for performance, efficiency, and long-term scalability.

Quick-Turn Flexible Assembly

We move at the speed of your ideas. Just upload your design files to get PCBAs delivered fast, through a secure, intuitive platform that protects your IP.

Expertise You Can Trust

We put quality and security at the forefront. Our experienced professionals follow strict standards to ensure reliability at every stage.

Why Engineers Choose BESTProto?

Short answer? Our people. While many EMS providers can procure the same equipment and tools, the difference in making sure your prototypes are completed on your demanding schedule is the BESTProto staff.

From the professional and trained inside project managers, to the process engineers handling the project, to the professional SMT and soldering technicians, the personnel at BESTProto make the difference. The close working relationship between the prototype builder and the designer or design team is crucial for success.

We speak the same language as you, making fast turnarounds of prototypes possible.
