Problems solved by technology

The former method is more suitable for vertical magnetic components, but the vertical components are often inconsistent with the flattening direction of the product; the latter method is mostly used on horizontal magnetic components, and the independent fastener assembly operation is more difficult for automatic machines.
[0004] Magnetic cores and coils are the necessary core materials for magnetic components. The most cost-effective design for forming magnetic components is to use only wire and magnets. The most streamlined process is to insert the magnetic core into a coil wound by insulated wire, and then glue it together. Bonding and fixing, but the gluing process is difficult to control its consistency, often causing fatal quality problems such as glue overflow, especially for surface mount components
