<p>PROBLEM TO BE SOLVED: To provide a pin connection structure which has minimum capacitance and imparts rigid mechanical fixture of a connector to a printed circuit board. SOLUTION: This connection structure is a structure, which imparts connection to a circuit board and includes a via having a plurality of diameters, a first section of the via having a first inside diameter, and a second section of the via which is positioned below the first section and has a diameter smaller than the first inside diameter. Practically, all the surface regions of the via is subjected to plating, and a plating surface of the via is formed.</p> |
