How Impact Electronics Scaled a Precision Laser Cooling Assembly for Ophthalmic Surgery from Prototype to Production

.

Quick Reference:

Company: Impact Electronic Solutions (Impact ES–Grants Pass)

Industry: Medical Device / Life Sciences

Application: Ophthalmic laser system — internal cooling assembly

Capabilities Applied: Precision electromechanical assembly, solenoid integration, DFM/DFT engineering

Certifications: AS9100D, ISO 9001:2015, IPC/WHMA-A-620D

Outcome: Prototype-to-production transition with no redesign; long-term manufacturing partnership

Summary:

Impact Electronics partnered with a medical device OEM to take a solenoid-controlled laser cooling assembly from early prototype into scalable production. By engaging at the design stage through DFM/DFT engineering services, the team eliminated the need for redesign, maintained clinical-grade tolerances throughout, and built a repeatable manufacturing process that scaled with the product.

The Challenge

A medical device OEM developing an ophthalmic laser platform needed a manufacturing partner capable of more than assembly. The internal cooling system, built around solenoid-controlled tubing and tightly routed internal wiring, was directly responsible for maintaining the thermal stability that surgical performance depended on. Any variation in build quality could affect clinical outcomes.

The OEM was at an inflection point: the design functioned, but a clear, scalable path to production had not yet been established. They needed a partner who could support early-stage builds, evaluate manufacturability before design lock, hold tolerances that clinical use required, and grow with the program without forcing a redesign.

The Solution: DFM-Led Electromechanical Assembly

Impact ES–Grants Pass engaged before the design was finalized—the point where manufacturing input has the highest leverage. Working directly with the OEM’s engineering team, the Impact team evaluated assembly sequencing, internal routing paths, and long-term production workflow to establish a process that was right on the first build and repeatable on every build after that.

Capabilities applied to the program:

  • Precision electromechanical assembly with controlled tolerances

  • Solenoid system integration within a constrained internal geometry

  • Tube routing and internal wiring documentation for repeatable production

  • DFM/DFT engineering services to improve manufacturability before design lock

  • Production process documentation and validation for long-term scalability

Impact’s 47,000-square-foot facility supports full-lifecycle manufacturing, from prototype and NPI builds through full-turnkey production. The same cross-functional team that developed the initial process managed the transition into volume manufacturing, eliminating the handoff risk that causes redesigns in other programs.

The Results

  • Prototype transitioned to full production with no redesign required

  • Cooling performance consistent across builds—a non-negotiable for surgical application

  • Manufacturing process fully documented and validated for scalability

  • Long-term manufacturing partnership established with the OEM

Frequently Asked Questions

What is DFM/DFT engineering, and how did it help this medical device program?

Design for Manufacturability (DFM) and Design for Testability (DFT) are engineering services that evaluate a product design before it is locked, identifying features that may be difficult or costly to produce at scale. For this ophthalmic laser program, early DFM engagement allowed Impact Electronics to improve assembly sequencing and routing before production began — eliminating the need for costly redesigns later.

Can Impact Electronics manufacture precision medical device assemblies at production volume?

Yes. Impact Electronics supports prototype builds, NPI, and full-turnkey production within a single 47,000-square-foot facility. Medical device programs benefit from the same engineering team across the full lifecycle, maintaining process continuity from first article through volume manufacturing.

What certifications does Impact Electronics hold for medical device manufacturing?

Impact Electronics holds AS9100D, ISO 9001:2015, IPC/ WHMA-A-620D, and IPC/WHMA-A-620D-S (Space addendum) certifications, along with Nadcap® accreditation for electronics — cable and harness assemblies. For medical device programs, the team applies the standard appropriate to the application, ensuring compliance without unnecessary cost.

How does Impact Electronics ensure build consistency in high-tolerance medical assemblies?

Every product undergoes 100% final testing and inspection using custom-built test boards developed by Impact’s in-house test engineering team. Production process documentation, copy- exact manufacturing methodology, and controlled assembly environments maintain consistency across every build.
