    摘要: An improved strain gage and an improved manufacturing method are disclosed. The strain gage includes a semi-rigid substrate having a thickness of 3 to 30 mils, a resistive strain sensitive foil bonded to the semi-rigid substrate for providing a resistance varying with strain associated with a surface to which the strain gage is attached, a first and a second terminal operatively connected to the resistive strain sensitive foil, and an anti-static layer. The improved strain gage allows for reduced labor content in manufacturing by allowing use of modern automated electronic component manufacturing equipment.

    摘要: Improved means of attaching electrical connectors to miniaturized electrical components are disclosed. Flexible leads separately attached to the front of an electrical component are attached at their opposite ends to more rigid electrical connectors on the reverse side of the electrical component. The electrical connectors and the electrical component are preferably bonded together for improved stability. The resulting electrical component is typically surrounded with at least one protective covering.
