Abstract:
A printed circuit board adapted for having surface electronic components soldered thereon during a solder reflow process wherein said printed circuit board moves in a predetermined direction during said solder reflow process, said printed circuit board comprising:a circuit portion having an electrical circuit thereon;a circumferential portion substantially surrounding said circuit portion;at least one elongated opening formed within said surrounding circumferential portion to be substantially parallel to said predetermined direction said printed circuit board moves during said solder reflow process to substantially prevent electronic component solder failures that occur as a result of the deflection of said printed circuit board during said reflow process;said circuit portion including at least one elongated perforation located therein adjacent and substantially parallel to said elongated opening in said surrounding circumferential portion; andan electronic component having a length dimension and positioned on said board so as to be oriented directly over said at least one elongated perforation within said circuit portion, said electronic component overlapping both said circuit portion and said surrounding circumferential portion, said at least one elongated opening positioned substantially parallel to said length dimension of said electronic component.
