Custom-Made Manufacturing Process for Micro-Coils

The use of micro-coils is increasing day by day in the medical and electronics fields. In order to prepare several modern devices, miniature micro-coils have become an essential component. From solar panels to medical equipment, micro-coils have significant usages for different purposes. Therefore, depending on the area of use and the requirements of customers, custom-made micro-coils can be of different types. Manufacturers now face a great challenge to satisfy the customers and to fulfil their requirements. Custom-made micro coils are those coils that fully focus on fulfilling the demands of the customers.


Due to miniaturized applications, customers mainly demand the manufacturing of tiny micro-coils. In the case of the manufacturing process, three things that the manufacturers consider are electrical efficiency, reliability, and manufacturing costs. Manufacturers always try to improve the reliability and electrical efficiency of the micro-coils. On the other hand, in order to reduce production costs, most manufacturers focus on mass production. The manufacturing process of micro-coils involves several steps such as casting, wrapping, winding, soldering, glueing, etc. Manufacturers also need to have certain technical expertise for providing good-quality micro-coils. 

Manufacturing Process: 

The manufacturing process of micro-coils requires isolated wires. These wires are wound around a core through the winding process in order to shape the coil. If the customers want coreless micro-coils, manufacturers remove the core after the finish of the winding process. Coreless coils have also significant applications such as in vain insertion. On the other hand, winding numbers determine the thickness of the micro-coils. 

Although for better conductive property, copper material is mainly used in the preparation of isolate wires, aluminum, stainless steel, gold, platinum, and titanium alloys can also be used depending on the requirements of the customers and the purpose of the use. However, the preparation of tiny micro-coils requires ultra-fine wires, otherwise, the size of the micro-coils will be large, and the coils will not fit into the miniature devices. Therefore, it is not an easy task to connect two different ultra-fine wires of different or similar diameters. In order to join these ultra-fine wires, well-known manufacturing companies are now using thermal compression bonding technology. This technology is very helpful to enhance the efficiency of the micro-coils and to conduct cost-effective mass production. 

Requirements for the Manufacturing of Custom-Made Micro-Coils:

In order to supply micro-coils depending on the demands and requirements of the customers, manufacturing companies need to have certain characteristics such as-

  • A manufacturing company should possess technological equipment that has a high notch facility.
  • The manufacturing process of micro-coils requires professional and experienced employees.
  • To satisfy the needs of the customers, manufacturers need to prepare unique type winding coils. 
  • As different customers need micro-coils of different shapes, the manufacturers should be able to create frames of various shapes.
  • The mass-production facility is also another essential criterion to fulfil high-speed orders.
  • Above all, a manufacturing company must assure the high quality of the micro-coils.

If a manufacturing company can satisfy the customers and consider innovation in the manufacturing process, the company can become very successful in the manufacturing of custom-made micro-coils.
