EBD coil-winding machines control wire tension to 0.1 gm and handle wire filaments to 0.0004-in. diameter and smaller. Mandrel wires on which the filaments wrap can be as small as 0.001-in. diameter.
Significant cost reductions and performance enhancements in planar magnetics have been introduced in recent years. These include replacing costly multilayer PCBs with lower-resistance flat coil ...
