Abstract:
A thermal management system for an electrical component includes a printed circuit board (PCB) capable of receiving the electrical component on a first side of the PCB. An elongate member has one end attached to a second side of the PCB, and another end disposed away from the PCB. The elongate member also has an open interior that facilitates fluid communication between the two ends. One of the ends defines an at least partially closed boundary on the PCB. The PCB includes an aperture disposed therethrough proximate the boundary such that fluid communication is facilitated between the first side of the PCB and the second side of the PCB, and along at least a portion of the elongate member.
Abstract:
The invention relates to a wire-printed circuit board or card (1) comprising conductors (6) that run on and/or in the circuit board or card between connection points (4). The aim of the invention is to improve a circuit board of this type. To achieve this, at least one of the conductors (6) has a rectangular or square cross-section. In addition, at least some of the conductors have a hollow cross-section, in which a coolant or heating agent circulates.
Abstract:
An interface includes floating pad metallization (30 or 630) patterned over a dielectric interface layer with a first portion forming a central pad (26 or 626) and a second portion forming an extension (28 or 628) from the central pad extending into an interface via. Another interface includes a floating contact structure including electrically conductive material (214) coating a hole with at least some of the floating pad metallization forming an extension (216) from the hole. A conductive contact area interface includes at least one interface structure (22, 24, 26, 28, or 30) coupled between first and second contact areas (112 and 118) and including an electrical conductor having a partially open interior to form a compliant joint between the first and second contact areas.
Abstract:
A connector (10) for microelectronic elements includes a sheetlike body (24) having a plurality of active contacts (22) arranged in a regular grid pattern. The active contacts (22) may include several metallic projections (28) extending inwardly around a hole (27) in the sheetlike element (24), on a first major surface (32). A support structure such as a grid array of noncollapsing structural posts (23) is on a second major surface (33), and each of the posts (23) is electrically connected to one of the active contacts (22). The grid array of the posts (23) and the grid array of active contacts (22) are offset from one another so that an active contact (22) is surrounded by several posts (23). The posts (23) support the sheetlike element (24) spaced away from a substrate (41) to which the posts (23) are attached. A microelectronic element (45) having bump leads (46) thereon may be engaged by contacting the bump leads (46) with the active contacts (22), and deflecting the sheetlike element (24) between the bump leads (46) on one side and the posts (23) on the other side.
