MINNEAPOLIS, Minn.—With a goal for benefitting medical device engineers, Precision, Inc. ( recently announced the launch of miniature coil manufacturing capabilities for medical navigation technologies. The assemblies feature ultra-fine wire winding in a wide variety of configurations, including unique angular winding configurations that allow for enhanced signal intensity.

Precision has the capability to produce miniature navigation coils with 58 AWG (0.00039 inch or 0.0099mm) ultra-fine wire winding, resulting in key real-estate savings and yield enhancement benefits for medical device design engineers. Miniaturization is a strong trend in medical navigation equipment as smaller technologies can reach otherwise inaccessible regions of the body, minimize disruption of regular body function, minimize energy consumption, and increase technology lifespan.

Medical coils produced in ISO 14644 compliant, Class 100,000 (ISO 8) clean room facilities with ultra-fine 58 AWG wire are said to generate significant real-estate savings. Specifically, the 58 AWG ultra-fine wire generates up to 50% space savings when compared to the use of 52 AWG wire and up to 30% space savings when compared to the use of 55 AWG wire. These real estate savings allow for the creation of smaller medical navigation technologies and also provide engineers with significantly enhanced design options in the design of new navigation technologies.

In addition to being able to produce miniature coils with ultra-fine 58 AWG wire, Precision, Inc., has knowledge of the associated processes required to ensure maximum yield. Precision's value-added services include expert handling, as well as microscopic soldering, terminations, and connections that ensure optimal performance. Precision has the capability to reduce costs by streamlining the supply chain—incorporating design, assembly, and packaging into a single supplier.

The company also has the capability to provide ultra-fine wire winding in a wide variety of configurations, including a unique-in-the-industry angular configuration. The angular winding configuration features wire at a 55° angle (known in the industry as the "magic angle") to the coil axis, which has been proven to improve signal intensity for optimal sensing performance.

This unique configuration greatly simplifies design processes, according to Precision. Previously, miniature coils required the addition of some element that would position the coil precisely at a 55° angle to the coil axis. Now the real estate and cost associated with this extra element are no longer required as the wire itself is already wound at a precise 55° angle to the coil axis. Removing the need for an additional angling element also ensures superior performance as fewer components provide fewer areas for error.

Precision, Inc. is a designer and manufacturer of custom and standard magnetic components and assemblies. The Minneapolis-based company has over 40 years of design experience and specializes in the creation of innovative and sophisticated solutions for solving customers' magnetic technology needs. Precision, Inc. uses cutting-edge materials and state-of-the-art design technology to deliver products across a broad range of industries, including renewable energy, medical device, aerospace/aviation/automotive, electronics, food processing, instrumentation, industrial control, telecommunications, and HVAC applications.
