Abstract:
A touch sensor device is provided that uses a flexible circuit substrate to provide an improved input device. Specifically, the present invention uses a touch sensor controller affixed to the flexible circuit substrate, which is coupled to a sensor component to provide a flexible, reliable and cost effective touch sensor suitable for a wide variety of applications. In one embodiment the touch sensor uses a flexible circuit substrate that provides relatively high temperature resistance. This allows the touch sensor controller to be affixed using reliable techniques, such as various types of soldering. The sensor component can comprise a relatively low-temperature-resistant substrate that can provide a cost effective solution. Taken together, this embodiment of the touch sensor provides reliability and flexibility at relatively low cost.

Methods for assembling a stack package for a high density IC module on a PCB include the steps of assembling a first layer of the stack package on the PCB, assembling a second layer of the stack package on the first layer and assembling a third layer of the stack package on the second layer, such that each layer is provided in electrical communication with the PCB. Additional layers may be added to the stack package.
Abstract:
A method of making a multilayered circuit assembly from a plurality of flat, flexible circuit elements, wherein each circuit element includes a substrate having conductive means to define an electrical path of travel which is formed between a base layer made of insulation material and a cover layer made of insulation material. Each circuit element has a connecting station associated with the conductive means. The method generally includes the steps of forming the conductive means on the base layer of each circuit element, punching a first opening through the conductive means and base layer at a connecting station of each circuit element, soldering the connecting station of each circuit element so that a solid solder pad fills the first opening whereby the solder electrically contacts the conductive means, punching a second opening through the cover layer of each circuit element, securing the cover layer of each circuit element over the base layer and conductive means so that the first opening is generally concentric with the second opening, punching a third opening in each circuit element through the solder pad, stacking a plurality of punched and soldered circuit elements on top of one another so that the third openings are generally concentric, inserting a terminal into the third openings of the stacked circuit elements so that a portion thereof contacts the solder, and staking the terminal so that the other surface thereof forms a cold weld interference fit against the solder.

Abstract:
A substrate structure and electronic device provide improved power integrity and simplified manufacturing. The substrate structure includes a first printed circuit board, having a first side and a second side opposing each other, and a plurality of passive components embedded in the first printed circuit board. The plurality of passive components includes a first group, including a plurality of first passive components disposed adjacent to each other, and a second group, including a plurality of second passive components disposed adjacent to each other. A smallest distance between the first and second groups is greater than at least one of a smallest distance between adjacent first passive components and a smallest distance between adjacent second passive components.
