Electronic circuit board and soldering method therefor

摘要

This invention discloses an electronic circuit board which can eliminate a soldering error for a component arranged such that its terminal array is perpendicular to the convey direction of the electronic circuit board which is to be flow-soldered, and a soldering method for it. An extending land (6) is formed to be substantially perpendicular to a convey direction (D) for flow soldering and to extend toward a downstream side of the warp of a board (2). <IMAGE>
