Claims

[Scope of utility model registration request]

Conductor patterns are formed on both sides of the substrate, and through holes are provided that penetrate between the conductor patterns on both sides.
In a double-sided printed board in which electrical connections are made between the conductor patterns by inserting connection pins into the through-holes, the conductor formed on one side of the board to be soldered to the tip of the board. 1. A double-sided printed board characterized in that a part of the periphery of a through-hole opening in a pattern is cut out so as to communicate with the through-hole.
