I have processed a batch of single silicon boards in the past few days. Maybe my friends are afraid of winding high-frequency transformers and find it difficult to make them. This thing is unclear at the moment, so I had to make one temporarily. Time is limited and the craftsmanship is not very beautiful. Just take it and understand it. First draw a schematic diagram:
The following is a schematic diagram of the production:
4 wires are wound in parallel, and there are 8 wires in two groups, which are welded to the transformer 1, 2, 3, and 4 pins, two wires for each leg.
Then go around together
Two turns after winding one layer
Wrap one layer with temperature-resistant insulating tape
After winding the second layer, leave the end of the line
The end of the welding wire is on the 5, 6, 7 and 8 pins of the transformer.
Look like this
Weld the heads of the merger together
In order to look beautiful after the tape is wrapped, add a layer of hard insulating paper.
Wrap it with temperature-resistant tape, and the wire package is completed
Installed finished transformer.
