<p>PROBLEM TO BE SOLVED: To provide a pin-erecting type printed circuit board which is constituted, in such a way that the solder used at the time of erecting a pin does not obstruct work performed on other portions by devising the shape and dimension of the used pin or changing the shape of a through-hole into which the pin is inserted. SOLUTION: A pin-erecting type printed circuit bard is constituted by planting a pin 3 in a blind hole 45A, having an internal wall composed of a conductor pattern for electrically connecting the inner-layer pattern 42 and lower outer- layer pattern 44 of a printed circuit board to each other, in such a way that the pin 3 is inserted into the hole 45A by a length shorter than the depth of the hole 45A and soldered 4 in the hole 45A. In addition, a small-hole section 45C for ventilation is made on the hole 45a.</p> |
