Performance-based Testing is Critical in Medical Device Construction
EIS utilizes a fully equipped test lab in determining whether materials meet customers' designed-in specs, often eliminating the need to test materials on the customer end.
Performance-based testing is critical in the medical device construction process, and our quality testing procedures cover medical-grade adhesive performance, electrical properties testing, and materials compatibility testing.
ADHESIVE TESTING
For medical manufacturers challenged with selecting the right adhesives, EIS performs adhesive testing to consider alternatives before investing in prototyping. We can recommend different adhesives based on the formulations and characteristics that are most important to the application, including biocompatibility, bond strength, flexibility, ease-of-use, price, availability, and manufacturability.
In addition to rigorous adhesive testing, EIS provides a range of materials from strategic partners, including 3M Medical Materials and Technologies, Adhesives Research Medical, DuPont Medical, and others.
ELECTRICAL TESTING
For converters and medical manufacturers designing for today's trends toward miniaturization and low power efficiency, they must carefully consider the electrical properties of the material and adhesive they select. EIS provides thorough electrical testing to ensure those materials meet all applicable specifications. Dielectric testing measures the value of a material or adhesive as an electrical insulator. An electrical test unit measures the resistance to the flow of an electric current, a critical test for both conductive and non-conductive materials and adhesives. Resistivity, the measurement of resistance, depends on the size and thickness of a material and temperature, humidity, and electrification time. Resistance is measured by:
- Surface resistance
- Bulk or volume resistance
- Contact resistance
Resistance and voltage testing provide precise measurements of the electrical properties of both the material and adhesive in use. Ultimately, accurate electrical properties testing can point out potential problems and lead to a solution involving a better-suited material.
