SUBSTRATE FOR SUSPENSION, METHOD OF MANUFACTURING SUBSTRATE FOR SUSPENSION, SUSPENSION, SUSPENSION WITH ELEMENT, AND HARD DISK DRIVE

摘要

PROBLEM TO BE SOLVED: To provide a substrate for suspension that exhibits excellent slider mounting performance and prevents a solder-caused short circuit.

SOLUTION: A substrate for suspension includes: a metal substrate; a base insulating layer formed on the metal substrate; and a conductor layer formed on the insulating layer and having at least connection wiring for connecting a slider mounting area and an external terminal part placed at an end opposite to the slider mounting area. A via made up of a conductive material filled in a though-hole formed in the insulating layer and connecting the metal substrate and wiring for the via is formed in the slider mounting area. A solder pad for connecting the connection wiring or the wiring for the via with a slider through solder is formed on the conductor layer in the slider mounting area. In addition, a dry film resist layer placed on the conductor layer and formed so as to surround the solder pad is placed in the mounting area. The resist layer has film thickness thicker than that of the via, and the slider is placed on the resist layer so as to keep parallel to the metal substrate.
