High frequency transformer production process - Insights direct from manufacturer
The high frequency transformer production line flow is as follows:
 First, incoming material inspection (quality control department is responsible for); 
Production preparation, such as copper back edge, core air gap, etc.; 
The first production and the first test should be carried out carefully when the new product is put into production; 
The winding package includes primary and secondary windings. Automatic, semi-automatic and manual winding machines should be used according to different windings. 
The ring type can be wound by machine or threaded by hand. 
The temperature of the pot is controlled according to the tin material. Test coil, including coil on-off, turns, short circuit, phase; Assemble the core to adjust the air gap; 
The comprehensive index includes inductance, leakage inductance, voltage resistance, insulation resistance, etc. 
Whether the product is pre-baked before impregnation can be determined according to the climate and conditions, according to the product requirements to use immersion, vacuum immersion, vacuum pressure immersion; Drop paint treatment before drying; 
The baked product should be soaked twice first to remove the paint layer on the lead line (wax can also be applied on the lead line to cancel the second dipping), 
then the comprehensive index retest, the quality control department sampling test, and then the appearance shaping, removal of surface paint nodks, cleaning; 
Finally, label, mark the inspection mark, pack and store.
