Planar Transformer Prototyping Kit
Document 355 Revised 05/19/08

An exploded view of the sample transformer is show in Figure 5. The sample
transformer provided with the kit consists of the following parts:
•
Two 6 Turn Primary Boards in series.
•
Four stamps — two stamps in parallel for each turn in series.
•
Seven insulators.
•
Six pins (3 large, 3 small).
•
One Core set (2 halves).
Assembly Procedure
Refer to Figure 5 and use the following procedure to assemble the sample
transformer.
1. Place one half of the Core on a clean working surface.
Note: Make sure that the centers of all parts are concentric.
2. Glue an insulator into the core.
3. Orient a Stamp 1 so that the terminals extend out of the core as shown in
the detail in Figure 5. Make sure the terminal holes will align with pins 7
and 8 of the Primary Board.
4. Place the stamp over the insulator.
5. Working from the bottom, insert two Large Pins (pins 7 and 8) into Stamp 1.
Note:
The bottom of the pins must be flush with the bottom of the core in
order to surface mount the completed prototype.
6. Ensure the pins are positioned so they are flush with the bottom of the core
and solder them to Stamp 1.
7. Place an insulator over the stamp.
