The manufacture of high frequency transformer should first consider the width, winding point and wire diameter. The good cooperation between them can effectively reduce the leakage inductance. When two wires are connected in parallel, three wires are connected in parallel, and multiple wires are wound in parallel, the selection of sleeve is also very important. The wire is flat and can be wound around.

1. In the winding process of transformer, its winding point and width are particularly important. When setting these two items, please note that the winding point must be 2 mm near the edge of the winding area of the skeleton, not near the skeleton; The setting of' width' is to subtract 3-5 mm from the effective winding area length of the actual skeleton, and the subtracted data is what we need when writing the program.

2. When setting the wire diameter, the wire diameter set by the program must be greater than or equal to the actual wire diameter, which means "close winding" when it is equal to the actual wire diameter, and "uniform distribution" when it is greater than the actual wire diameter. According to this idea, we can use it flexibly in production and processing.

3. In processing, if the enameled wire wound in some winding steps can't be wrapped round, it is necessary to change its winding point and wind the enameled wire in the middle.

4. In this process, always pay attention to the foot position of the transformer to avoid wrong foot position.

5. After processing, the enameled wire on its pin must be treated with a blade to prevent short circuit of both feet.

6. For transformers with shielding copper skin requirements, solder joints must be placed above the skeleton.

7. When fixing the magnetic cores, the two magnetic cores must overlap. It is forbidden to overlap up and down. When winding the horse's leash, tie it tightly with a little force.

8. The transformer must be tested before dipping the insulating paint, and the unqualified products must be reworked in time to make OK products flow into the next step for dipping treatment.

9. When using the vacuum impregnation machine, you should operate in strict accordance with the operating instructions.

10. When using the oven, the baking temperature should not exceed 1 10 degrees, and the time must be controlled well. All transformers must be dried in the shade before entering the oven. The product was baked at 80℃ for 65438±0H hours, and then at 65438 000℃ for 3 hours. During baking, adjacent transformers are used to prevent adhesion.

1 1. When testing finished products, the test data should be counted.
