Abstract:
PROBLEM TO BE SOLVED: To provide a printed circuit board with a built-in electronic component which is provided with superior electrical reliability by directly bonding an electrode of an electronic component, and a bonding layer to connect the electronic component, and to provide a method for manufacturing it. SOLUTION: The printed circuit board with a built-in electronic component provided with an external electrode comprises a base material 31 in which an inserting hole 33 for housing the electronic component is formed, a filling material 37 with which a gap between the electronic component and the inserting hole 33 is filled to fix the electronic component, and the bonding layer 41 which is laminated on the base material to be connected to the electrode. A circuit is formed on the bonding layer. COPYRIGHT: (C)2007,JPO&INPIT

Abstract:
L'invention concerne un procédé et un dispositif d'interconnexion en trois dimensions de composants électroniques. Pour diminuer les capacités parasites entre connexions et blindage (304) du dispositif, on découpe, dans le bloc (3') de circuits empilés dont les conducteurs (21) sont en retrait de la face correspondante (302) du bloc, des rainures (40, 41) métallisées (42), ces rainures venant entamer les conducteurs de connexion (21). L'ensemble est ensuite enrobé de résine (303) et blindé par une métallisation (304). L'invention s'applique notamment à la réalisation de systèmes électroniques en trois dimensions à encombrement réduit.
Abstract:
A surface mount circuit protection device (10) includes a laminar PTC resistive element (12) having first and second major surfaces and a thickness (t) therebetween. A first electrode layer (14) substantially coextensive with the first surface is formed of a first metal material of a type adapted to be soldered to a printed circuit substrate. A second electrode layer (16) formed at the second major surface includes a structure forming or defining a weld plate (18). The metal weld plate (18) has a thermal mass and thickness (t w ) capable of withstanding resistance to micro-spot welding of a strap interconnect without significant resultant damage to the device. The device (10) is preferably surface mounted to a printed circuit board assembly forming a battery protection circuit connected to a battery/cell by battery strap interconnects, wherein one of the battery strap interconnects is micro spot welded to the weld plate of the device.
