Abstract:
The invention provides a power semiconductor module including a power converter module with an improved configuration technology that minimizes or eliminates the need for a positive bonding (soldering/adhesive) connection between a power semiconductor element and a contact surface of a substrate. The present invention includes a housed or encapsulated power semiconductor element with a pre-secured connecting element that reduces manufacturing time and costs, while improving performance capability in a decreased size.
Abstract:
Spring contact elements are fabricated by depositing at least one layer of metallic material into openings defined in masking layers deposited on a surface of a substrate which may be an electronic component such as an active semiconductor device. Each spring contact element has a base end, a contact end, and a central body portion. The contact end is offset in the z-axis (at a different height) and in at least one of the x and y directions from the base end. In this manner a plurality of spring contact elements are fabricated in a prescribed spatial relationship with one another on the substrate. The spring contact elements make temporary (i.e., pressure) or permanent (e.g., joined by soldering or brazing or with a conductive adhesive) connections with terminals of another electronic component to effect electrical connections therebetween. In an exemplary application, the spring contact elements are disposed on a semiconductor devices resident on a semiconductor wafer so that temporary connections can-be made with the semiconductor devices to burn-in and/or test the semiconductor devices.
Abstract:
An electronic package and information handling system utilizing same wherein the package substrate includes an internally conductive layer coupled to an external pad to provide reinforced adhesion of the pad to the substrate to substantially prevent cracking, separation, etc. of the pad when the pad has a pin bonded thereto and the package is coupled to an external substrate (e.g., printed circuit board). The reinforced adhesion also prevents pad separation, etc. during periods of package handling, manufacture, etc.
Abstract:
An interconnection apparatus and a method of forming an interconnection apparatus. Contact structures are attached to or formed on a first substrate. The first substrate is attached to a second substrate, which is larger than the first substrate. Multiple such first substrates may be attached to the second substrate in order to create an array of contact structures. Each contact structure may be elongate and resilient and may comprise a core that is over coated with a material that imparts desired structural properties to the contact structure.
Abstract:
An alignment weight is provided. The alignment weight includes a body of material having first and second opposing surfaces. A number of depressions are formed in the first surface. The depressions receive pins of a floating pin field when placed on a floating pin field during connection of the floating pin field to a printed circuit board.
Abstract:
Surface-mount, solder-down sockets permit electronic components such as semiconductor packages to be releasably mounted to a circuit board or other electronic component. In an embodiment, resilient contact structures extend through a support substrate, and solder-ball (or other suitable) contact structures are disposed along the bottom of the support substrate in electrical contact with the ends of the resilient contact structures. Composite interconnection elements are used as the resilient contact structures disposed atop the support substrate. In an embodiment intended to receive an LGA-type semiconductor package, pressure contact is made between the resilient contact structures and external connection points of the semiconductor package with a contact force which is generally normal to the top surface of the support substrate. In an embodiment intended to receive a BGA-type semiconductor package, pressure contact is made between the resilient contact structures and external connection points of the semiconductor package with a contact force which is generally parallel to the top surface of the support substrate.
Abstract:
Spring contact elements are attached to terminals of an electronic component, which may be a semiconductor die. The spring contact elements may comprise a flexible precursor element. The precursor element may be over coated with a resilient material. The spring contact elements may be elongate and attached to the terminals at one end. The other end of the spring contacts may be spaced away from the electronic component.

Solder joints coupling pins to a microelectronic package substrate are enshrouded with an encapsulation material. In this manner, pin movement is limited even if the pin solder subsequently melts.
Abstract:
A printed wiring board has a circuit substrate 6 having a conductor circuit 5 and a through hole 60, and also has a joining pin 1 inserted into the through hole. The joining pin is manufactured by using a material unmelted at a heating temperature in joining the joining pin to an opposite party pad 81. The joining pin is constructed by a joining head portion 11 greater than an opening diameter of the through hole and forming a joining portion to the opposite party pad, and a leg portion 12 having a size capable of inserting this leg portion into the through hole. The leg portion is inserted into the through hole and is joined to the through hole by a conductive material such as a soldering material 20, etc. A joining ball approximately having a spherical shape instead of the joining pin can be also joined to the through hole by the conductive material.
