Abstract:
PROBLEM TO BE SOLVED: To provide, at low cost, a small-sized and light-weighted electric connection box which is excellent in recyclability and soaking/heat dissipation, and besides not restricted in mounting position. SOLUTION: The electric connection box 11 is composed of a circuit board 14 where electric parts are mounted, and an upper case 12 and a lower case 13 which cover the circuit board 14. A metal core board where the surface of a plate-shaped metal core 24 is covered with an insulator 25 is used as the circuit board 14, and a part of the metal core 24 is bent to serve as a terminal 23 for heat radiation, and exposed to the outside at an engaging recess 21 which constitutes a socket 16 equipped with a heat radiating function formed in the case 12. A heat radiating member 41 is connected to the terminal 23 for heat radiation by connecting the connector 31 equipped with a heat radiating function to the socket 16 equipped with a heat radiating function.

This disclosure suggests microelectronic substrates with thermally conductive pathways. In one implementation, such a substrate includes a body and a thermally conductive member. The Body has a first surface that includes a microelectronic component mounting site, a second surface separated from the first surface by a thickness, and an opening extending through at least a portion of the thickness. The opening is outwardly open at one or both of the surfaces and has a first portion having a first transverse dimension and a second portion having a larger second transverse dimension. The thermally conductive member includes a first thickness, which is received in the first portion of the opening , and a second thickness , which is received in the second portion of the opening. A transverse dimension of the second thickness of the thermally conductive member is greater than the first transverse dimension of the opening.
Abstract:
A substrate (1,2,3) for mounting an electronic component (6) or components thereon. The substrate comprises a core substrate (20) and at least one insulation layer (22,22') on at least one side of the core substrate, and a patterned wiring line layer (24,24') formed on at least one insulation layer. The core substrate (20) includes holes (26a) in each of which a lead pin (6a) of an electronic component (6) may be inserted, and is provided with lands (10) each of which surround the opening of a hole and to which the lead pin (6a) inserted in the hole is bonded. The insulation layer (22,22') or layers has bores (11), which expose the land at their bottom ends, and thereby communicate with the holes. A method of manufacturing such a substrate is also disclosed.
Abstract:
The invention aims to raise the packing density of electronic circuits and printed conductor structures on circuit boards intended for electrical apparatus having HF components, notably mobile radiocommunications equipment. To this end, a 'micro via' layer (M2) is first applied to one or both sides of a circuit board substrate (LPT4). Thereafter, especially HF circuits and HF printed conductor structures (LBS3HF) are placed onto at least part of the 'micro via' layer (M2). The HF circuits and HF printed conductor structures (LBS3HF) are protected in relation to an HF mass layer of the circuit board substrate by blocking zones arranged in a substrate layer (LPL2) of the circuit board layer situated directly below the 'micro via' layer (M2) against interfering influences which affect the HF parameters to be adjusted of the HF circuits or HF printed conductor structures LBS3HF).
