Medical Device Inspection plays a critical role in manufacturing advanced healthcare technologies. Engineers secure stable electrical contact and maintain high repeatability, even in harsh operating environments. Seiken designs and builds custom test fixtures to overcome complex inspection challenges for micro-sized and uniquely shaped components, boosting precision, reliability, and production efficiency.
Customer Challenges / Request
For a specialized micro component used in medical devices, a high-voltage application process is required to ensure performance and reliability. The component features a rod-shaped metal insert, demanding precise electrical contact at both the outer surface and the internal conductor. During testing, several hundred volts are applied while the part is immersed in insulating oil—making stable, repeatable contact absolutely critical. Achieving consistent results under these demanding conditions requires advanced custom test fixture design tailored for medical device inspection environments.
Our Solution
- High-Heat-Resistant Probe Integration
We selected high-heat-resistant probes to withstand several hundred volts and match the specific electrical and environmental demands of the medical device testing application. These probes maintain consistent conductivity and deliver long-term durability under demanding inspection conditions.
- Secure Probe Fixation with High-Temperature Adhesives
We applied high-temperature industrial-grade adhesives to secure the probes and prevent movement during inspection. This approach increases testing repeatability, improves measurement accuracy, and reduces process variability.
- Insulating Oil Compatibility & Optimized Wiring
Our engineers designed the custom fixture for operation in insulating oil environments. We selected dedicated connectors and wiring to maintain reliable signal transmission and integrate seamlessly with measurement equipment, supporting high-voltage medical device validation.
Results & Benefits
- Precision Contact Alignment with Integrated Guide Pins
We integrated guide pins into the custom inspection fixture to eliminate contact misalignment during component insertion. This design keeps probes aligned with designated contact points, strengthens measurement stability, and increases repeatability and overall inspection reliability in high-voltage medical device testing.
- Increased Operational Efficiency with Single-Sided Probe Design
Our team replaced the dual-sided clamping concept with a single-sided probe configuration to simplify assembly and inspection processes. This change reduces workload, improves operator usability, and shortens cycle time—driving higher productivity in medical device manufacturing.
- Enhanced Safety and Long-Term Durability
We incorporated high-heat-resistant probes to support operation in insulating oil and high-voltage environments. Our engineers precisely control probe contact force to maintain consistent electrical performance and mechanical strength. This approach delivers a safer, more durable custom test fixture for demanding medical device inspection applications.

Beyond the semiconductor and electronics industries, Seiken also designs and manufactures custom inspection and test fixtures for medical devices and other advanced applications. Our engineering team oversees every stage of development—from material selection and precision fixture design to production-floor optimization—ensuring reliable, repeatable, and highly efficient testing solutions.
In specialized measurement environments, such as cell culture experiments where high humidity or chemical mist may be present, electrical conduction through probes may be required. To address these demanding conditions, we manufacture probes using highly corrosion-resistant materials that maintain performance and durability over use.
In addition, we offer comprehensive solution proposals tailored to specific applications and testing conditions. These range from selecting optimal materials for environments involving high temperatures, high voltages, or non-magnetic requirements, to designing fixtures that account for practical considerations in real-world operational settings.
If you face challenges with uniquely shaped components or inspection demands that standard fixtures cannot solve, our engineers will develop a tailored solution.
