Abstract:
A substrate for mounting an electronic part comprising:an insulating substrate provided with a conductive circuit, said insulating substrate having a through hole;a conductive pin having a leg and a head inserted into said through hole, wherein said head of said conductive pin includes a plurality of projections at its side wall, each projecting radially in 4 or more directions, said projections forming a plurality of projection pairs, each projection of which is extending in an opposite direction from an axial center of said head, said projection pairs including a primary projection pair having the largest length and a secondary projection pair having the next largest length, said length of said primary projection pair is equal to or more than an inside diameter of said through hole, wherein said primary and secondary projection pairs are configured such that they do not deform upon insertion into said through hole;wherein said primary and secondary projection pairs are configured such that said primary projection pair causes an outward deformation of said through hole aligned generally with said primary projection pair, and an inward deformation aligned generally with said secondary projection pair;wherein said secondary projection pair is configured to allow said through hole to deform inwardly in response to the outward deformation caused by said primary projection pair.
