Description

Technical Field

[0001] The invention relates to the technical field of electronic network transformers, and in particular to a manufacturing process of a PIN-type network transformer. Background Art

[0002] In the field of network transformers, the main structural components of the product include metal PIN, base and coil. The three components are assembled to form a functional product. The metal PIN on the internal components of the product needs to be inserted into the base to form a module; then the copper wire of the coil is wrapped around the metal PIN of the module, and then the copper wire and the metal PIN are connected by forming a welding point through dipping in flux and high-temperature tinning. After tinning, the residues generated during the tinning process need to be removed by cleaning, and then the moisture is removed by baking. This method has many production processes and high processing costs.

[0003] Moreover, high-temperature tinning will make the copper wire thinner, causing the risk of wire breakage; there is a probability that the flux cannot be completely cleaned during cleaning, which will cause the risk of flux corroding the copper wire. Summary of the invention

[0009] Step 3, inserting the PIN into the base;
