Information Center

1

What types of medical devices do you support with PCB assembly? 

We provide PCB assembly services for a wide range of medical devices across multiple risk classes. Our experience includes diagnostic equipment, patient monitoring systems, therapeutic and rehabilitation devices, medical aesthetic platforms, and surgical systems.

2

Can you support both,low-volume and full-scale production?

Yes. Our medical PCB assembly solutions are customized as per your volume needs. We help you scale efficiently from prototypes and pilot builds to mass production. Our teams participate early through DFM reviews, tooling development, and process validation to streamline production scale-up.

3

How do you maintain consistent quality across different production volumes?

We apply strict process control and inspection rigor across all volumes using in-line 3D AOI, in-circuit testing, functional testing, and X-ray inspection where required. Each production stage includes traceability and monitored checkpoints, allowing issues to be identified and addressed before they affect downstream processes.

4

Are your PCB assembly processes compliant with medical regulations?

Our PCB assembly processes follow global regulatory and environmental requirements applicable to medical device manufacturing. We operate within an ISO 13485–certified framework and conform to IPC-A-610 Class 3 standards, along with FDA 21 CFR Part 820 and relevant IEC requirements.

5

Do you provide Design for Manufacturability (DFM) support?

Yes. Our engineering teams engage early in the design phase to conduct DFM and DFA reviews. This approach helps reduce production risk and supports smoother transitions from development to manufacturing.

6

How do you support programs with changing volumes or product variants?

We manage changing volumes and product variants through flexible production planning, buffer strategies, and close coordination with customer teams. Agile work cells, digitally guided work instructions, and disciplined lean manufacturing practices support quick transitions between variants while maintaining throughput across high-mix, low-volume builds.
