a method of making a printed circuit board including the steps of: providing a board with electrical conductor traces; applying a solder material to at least one selected location on a first side of the board; placing a first component on the first side of the board; heating the board and solder material to reflow the solder applied to the first side of the board to provide an electrical connection of the first component with a first conductor trace portion of the board; and then connecting a second component to the board and providing a nonsoldered electrical connection between the second component and a second electrical conductor trace portion of the board.
