Abstract: An electronic circuit, comprising: an integrated substrate structure comprising one or more electrically conductive traces comprising plating on a laser-etched, non-conductive isolated portion of the integrated substrate structure defining each electrically conductive trace; one or more electrically conductive pads at one or more predetermined positions along the one or more electrically conductive traces; and an electrical component surface mounted to the at least one electrically conductive pad with interconnect and bonding material.

Abstract: A system and method for forming a stretchable conductive circuit package that utilizes an addition and condensation mechanism incorporated into one system. When the stretchable conductive ink is used in a circuit package, the circuit package has high reliability and durability.

Abstract: A method for forming a circuit pattern on an integrated substrate structure includes providing an insulating surface which includes a pattern forming portion. An activation ink is deposited only on the pattern forming portion to form a non-conductive isolation layer. A first metal layer is formed on the non-conductive isolation layer by electroless plating. A patterned portion of the first metal layer is isolated from a remaining portion of the first metal layer to form the circuit pattern. A non-conductive masking layer is applied on the first metal layer. A second metal layer is formed on the non-conductive masking layer. A surface mount land pattern and pad configuration is determined. A solder mask layer is applied to the patterned portion. A protective layer is applied to protect pad areas not covered by the solder mask layer. An electrical component may then be mounted to the pad(s).
