In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. The circuit decal includes conductors which function as an internal signal transmission system for the component, and a mask layer which functions as a solder mask and an outer insulating layer for the component. Also included is a powered door opener for attaching with a refrigerator door and automatically opening the refrigerator door after the door seal is broken. The locking member may engage the bar by displacement of an end of at least one tongue as a result of deformation of a tongue actuating tab during compression between the nut and a second structure.
