Abstract: A compliant circuit element spacing system comprises a circuit board, a dummy spacer component, and a compliant circuit element. One or more active components are mounted to the circuit board. The dummy spacer component is also mounted to the circuit board, such that the dummy spacer component is electrically isolated from each active component mounted to the circuit board. The compliant circuit element is positionable proximate the circuit board, and spaced from the circuit board by the dummy spacer component. The spacing component isolates the compliant circuit element from each active component mounted to the circuit board.

Abstract: A circuit board assembly (10) comprising a laminate substrate (12) and a surface mount device (18) having a CTE less than that of the laminate substrate (12) and attached with at least one solder joint (20) to a first surface (14) of the laminate substrate (12). The assembly (10) further includes a localized stiffener (24,124,224) attached to a second surface (16) of the laminate substrate (12) so as to be directly opposite the circuit device (18). The localized stiffener (24,124,224) is formed of a material and is shaped so that, when attached to the laminate substrate (12), the stiffener (24,124,224) is capable of increasing the thermal cycle fatigue life of the one or more solder joints (20) that attach the device (18) to the substrate (12).

Abstract: A method for vertical removal of excess solder from a circuit substrate includes the use of a sacrificial circuit substrate (60) with a plurality of pads and vias that are solder-wettable. The pads and vias of the sacrificial circuit substrate are placed (64) in vertical proximity to the excess solder of the circuit substrate. The excess solder is heated (66) until it is liquid, wherein the excess solder is wicked (68) vertically onto the pads and into the vias of the sacrificial circuit substrate. Thereafter, the sacrificial circuit substrate is lifted (70) from the proximity of the circuit substrate while the solder is in a liquid, taking the excess solder with it but leaving a predetermined amount on the circuit substrate.

Abstract: A module component in which mounting components and a conductive partition for dividing into a plurality of circuit blocks are mounted on a substrate. The circuit blocks are covered with a sealing member, which is further covered on its surface with a conductive film to electrically shield the circuit blocks individually. This module component can maintain bending strength, with little warpage by a sufficient shielding effect achieved without increasing the number of manufacturing processes.
