Title: Method of connecting terminal posts of a connector to a circuit board

Abstract: A method of connecting the terminal posts of a connector into holes in a circuit board comprising the steps of inserting solder elements, which can have the shape of a doughnut or torus, for example, around each terminal post; inserting a piece of material, such as a strip of plastic or a Styrofoam material rod having a width or diameter greater than the distance between the two rows of terminal posts, in between said two rows of terminal posts to hold the solder elements on the posts; inserting the terminal posts in the holes prepared therefor in the circuit board; removing the strip or rod of material; further inserting, if necessary, the terminal posts into the circuit board holes; and heating the solder doughnuts by appropriate means while the terminal posts are pointed downwardly, that is with the circuit board below the connector, to reflow the solder into the spaces between the holes in the circuit board and the terminal posts therein.
