Suspension board assembly sheet with circuits and method for manufacturing the same

摘要

A plurality of suspension boards and an inspection substrate are integrally supported by a support frame. In each suspension board, a line is formed on a conductive first support substrate via a first insulating layer. The first support substrate and the line are electrically connected by a first via in the first insulating layer. In the inspection substrate, a conductor layer is formed on a conductive second support substrate with a second insulating layer sandwiched therebetween. The second support substrate and the conductor layer are electrically connected by a second via in the second insulating layer. The first via and the second via have the same configuration.
