摘要： In a method of attaching an electronic component to a printed circuit board by a plurality of screws that are inserted into corresponding through holes cut in the board from a surface of the board and then screwed into corresponding screw holes formed in the component mounted on an opposite surface, the component is screwed onto the board using one of the screws and the component and the screw are soldered onto the board with lead-free solder. After they have been cooled down, the component is screwed onto the board using remaining screws. With this, the strength of the connection between the component and board is improved and also the occurrence of warp of the board and component can be prevented.
