<P>PROBLEM TO BE SOLVED: To cope with such a problem that incorrect installation of an electrode occurs frequently because an LED must be reversed for installation in the mounting method for embedded type substrates such as a subminiature CSP or the like, and as a result, returning of the substrates and request for repair increase. <P>SOLUTION: A mark is put on the flat surface of an LED package to discriminate the direction of an electrode of anode and cathode, and a recessed mark is also put on the center of a circumference on its bottom so as to discriminate electrodes. Thus, incorrect judgment of the polarity is prevented during discrimination of polarity while a substrate is mounted, and the yield is improved. In addition, the mark for discriminating polarity is put on the center of the rear surface, so that it is prevented from being hidden by a lead when the lead is bent to the rear surface. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
