Precision is a crucial part of magnetic coil windings. Precision winding of the wire coil ultimately affects the performance, efficiency, and reliability of the component, be it a transformer, inductor, or power supply, which in turn can have a major impact on the performance of the larger, end-use assembly. And when it comes to manufacturing electronics for military and aerospace applications, good precision prevents critical equipment failures and ensures performance even in bad environments.
At SI Manufacturing, we regularly manufacture custom magnetics that have to meet MIL standards for use in Defense equipment, aircraft, satellites, and even space exploration. And whether it’s a simple component or a full box build and wire harness assembly, oftentimes none of it would function to spec without expert precision winding of the magnetic coil.
Why Precision Matters in Coil Windings
Windings are the most important part of any transformer, inductor, or similar magnetic component, serving as a medium for energy transfer, magnetic coupling, energy storage, and energy conversion depending on the part. It’s far more complex than just winding a wire around the core–proper configuration has a direct impact on electrical resistance, inductance, loss, thermal performance, and much more.
By manipulating the number of windings around the core, the type and number of wire coils used, the shape of the winding itself, and even the distance between the individual windings, among many other factors, the manufacturer can adjust the performance of the magnetic component to the customer’s specifications. And because magnetics are so crucial to nearly every type of electronic assembly, precise coil windings even affect the function of end-use products and equipment.
Precision Winding that Meets Military Standards
Military standards for custom magnetics, such as the MIL-STD-981 for Space Applications, lay out thorough guidelines and quality standards for every single aspect of magnetics manufacturing–including coil windings. In these types of applications, higher precision not only means better performance, but also mission-critical reliability, extended durability, reduced EMI and performance drift, and even the prevention of critical failures.
At SI, we specialize in full electronics manufacturing that meets these types of rigorous standards. We manufacture magnetics of every size, description, encapsulation, and winding type, all of which go through required testing and quality inspections. All of our performance and quality examinations, including electrical, functional, visual, mechanical, and environmental testing, are completed in-house for improved production efficiency and consistent quality management, while meeting industry standards.
