Abstract:
A secondary cell protection circuit device comprising a PCB board, a PTC element integrally formed on the PCB board and a circuit provided on the board and adapted to control the voltage and current of a secondary cell; and a secondary cell assembly provided with the device. A PCB board (1) provided thereon with an electronic part (2) and a PTC element (3), wherein the PTC element (3) comprises a PTC material (6) sandwiched between upper and lower nickel foils (71, 72), an output electrode (4) disposed on the foil (71) and an output electrode (5) disposed under the foil and soldered to the PCB board (1).
Abstract:
A circuit protection device (31) suitable for surface mounting on a substrate (19). The device has a laminar PTC resistive element (3) which is composed of a conductive polymer composition and is positioned between first and second electrodes (5, 7). Attached to the first electrode is a first electrical terminal (33) containing an electrically conductive material which has a first attachment portion (35) connected to a first flexible portion (39) by means of a first connection portion (47). At least part of the first flexible portion is free of attachment to the first electrode. The first attachment portion is coplanar with at least one of the first connection portion and the first flexible portion, The first attachment portion may contain a slot (49) and a solid hinge portion (51). When the device is mounted on a substrate by means of a mounting component (41) extending from the first terminal, the first flexible portion allows contraction and expansion of the conductive polymer despite the rigid attachment of the mounting component onto the substrate.

Abstract:
Es soll eine einfache automatisierbare und wärmestabile Halbleiterkontaktierung für lineare und flächige SMD-Bauteile, insbesondere LED-Anordnungen verwirklicht werden. Hierzu werden auf eine mit Leiterbahnen beschichtete Trägerfolie SMD-Bauteile aufgesetzt, wobei die Leiterbahnen zur einfacheren Kontaktierung durch Aufschmelzen entweder ganz oder teilweise aus lötbarem Material bestehen.
Abstract:
A manufacturing technique for constructing passive electronic components in vertical configurations is disclosed. Electrically passive components are constructed in a structure that is substantially perpendicular to target platform including a first plane to provide a larger electrode contact area and a smaller physical dimension. Passive components structured to be substantially perpendicular to a plane associated with a target platform can be directly connected to pad contacts of an integrated circuit or substrate or can be embedded in a package to reduce the area overhead of a passive component while improving the effectiveness of the passive components in their applications.
