Transforming Winding Techniques: Key Insights into Vertical and Horizontal Bobbin Methods

Introduction ：
Vertical Bobbin Winding Method:
The vertical winding technique employs different wire sizes, depending on the application:
1.Thick Wire: A 0.8φ wire is wound one turn above the winding wire.
2.Fine Wire: A fine wire ranging between 0.2φ to 0.8φ is wound around the bobbin for 1.5 turns.
3.Extremely Fine Wire: For finer windings, a wire under 0.2φ is used to wrap 2 to 3 turns below the primary winding.
The key principle behind the vertical winding method is to ensure the winding line is pressed tightly without surpassing the convex point of the bobbin. This prevents overcompression or inefficiency in the winding structure.

Horizontal Bobbin Winding Method:
The horizontal method typically involves winding the wire around the bobbin in approximately 2 to 3 circles. However, unlike the vertical technique, the winding does not extend all the way to the end of the bobbin. This step is crucial to avoid overheating or damaging the bobbin during the soldering process. In special cases, where strict width limitations apply, the winding can be pressed all the way to the end of the bobbin, but care must be taken to avoid any excess pressure during soldering. After soldering, the edge pins are cut to reduce the overall width of the transformer.
Practical Application:
In scenarios where width constraints and stringent specifications are involved, the horizontal winding method may be preferred. It is important to follow the winding guideline carefully to ensure the final product meets both performance and size requirements without compromising the structural integrity of the bobbin.
These methods offer flexibility in transformer design, balancing performance and dimensional constraints for optimal results.
