Abstract:
A manufacturing method for manufacturing a substrate for mounting electronic parts, comprising:forming a substrate having at least one electronic parts portion capable of receiving electronic parts;forming holes in a periphery region of said at least one electronic parts portion;forming an electrode film on an inner surface of said holes thereby forming electrode holes each having a hole center and an inner radius R; andcutting said substrate with a blade through said holes at a blade position offset from said hole centers toward said at least one electronic parts portion so as to form concave arcs each having a height H=R-d,wherein d is a distance between one of said hole centers and a surface of said blade facing said at least one electronic parts portion,H.ltoreq.0.3 R, andwherein the step of cutting said substrate is performed such that each concave arc formed on said substrate has essentially a same height.
