Abstract
Abstract A printed circuit board ( 23 ) used in a modular jack ( 1 ) includes a plurality of insertion holes ( 231, 232 ) defined through an upper side and a lower side thereof. A conductive layer coating ( 235 ) coats an inside of each insertion hole and a conductive base ring ( 236 ) forms a rim around each end of each hole. A solder mask ( 230 ) covers portions of a front and a rear surfaces of the printed circuit board around the insertion holes. The solder mask covers over the base rings and extends a short distance into each insertion hole, thereby increasing a creepage distance between conductive layer coatings of adjacent holes. This protects the printed circuit board from short circuiting.
