First Claim
Patent Images
1. A method of mounting a dc/dc power converter on a printed circuit board comprising:
- providing a dc/dc converter comprising;
a converter substrate having circuitry thereon; and
at least one rigid terminal pin attached to the converter substrate, the pin being electrically connected to the circuitry, the terminal pin including a flange having a shoulder spaced from the converter substrate;
applying solder to at least one of the shoulder of the flange and the circuit board;
positioning the dc/dc converter to the printed circuit board with the terminal pin extending through a circuit board hole and the shoulder abutting the circuit board to accommodate spacing of the dc/dc converter from the circuit board with solder between the shoulder of the flange and the printed circuit board; and
subjecting the dc/dc converter and printed circuit board to a solder reflow process to join the terminal pin and printed circuit board with the solder.

Abstract
A dc/dc converter is mounted to a printed circuit board with rigid terminal pins which extend into a converter substrate to provide electrical connection to circuitry on the substrate. A terminal pin includes a flange which abuts the printed circuit board and spaces the converter substrate from the printed circuit board. Connection to the printed circuit board is made by solder provided between the flange and the circuit board.
