Micro coil

KUK winds the smallest micro coils of the world, with both magnetic and air core. The production of micro coils with magnetic cores is one of KUK's specialities. We have established a great deal of know-how in handling windings directly onto magnetic cores - with a wide variety of wires that are invisible to the naked eye. Thanks to integrated plant and tool construction, KUK Group has the capabilities to process ultra-fine wire from 10 µm and to produce micro coils with diameters from 0.3 mm. For miniature coils with magnetic cores, cores made of a wide variety of materials are possible, including mu-metal, ferrite or amorphous materials. Custom coil solutions can be developed with guide configurations for manual assembly or surface mount SMD coils for delivery in tape and reel, allowing automated reflow processes for PCBA. Our micro coils can be wound with copper, silver, gold or other wire alloys. Various coatings, overmoulding, packaging and test options are available. KUK offers these advantages in the production of customer-specific micro coils with magnetic cores: - Great experience in processing ultra-fine wires - Know-how about various conductor and core materials - High-precision miniature winding machines from our in-house automation department - Customer-specific test methods - Flexible semi-automatic production capacities in Asia, Europe and Africa
