Printed Circuit Transformer or Integral Printed Circuit Board Transformer

A low profile transformer design eliminates hand winding of wiring and also eliminates hand mounting of the transformer to a printed circuit board (PCB) by making the transformer an integral part of the PCB. The transformer is constructed as described in the following:

The printed circuit transformer consists of two components: a multi-layered PCB and a cup core. The printed circuit component is shown in Fig. 1, a top view of the transformer with the printed circuit lines. The printed circuit winding begins on the top plane of a multi-plane printed circuit board, and the winding exits on the second or bottom plane of the board as shown.

The side view of the printed circuit board (Fig. 2) shows the cup core positioned on the board. The circular cup core hole's placement in relation to the circuit winding is shown in Fig. 1.

The method of constructing this configuration is: First, etch the printed circuit winding on the top copper surface. Second, the holes to accommodate the cup core are drilled. Last, the cup core is attached to the board by mechanical means or by an adhesive.
