Abstract:
This invention relates to a right-angle light-emitting diode assembly with snap-in feature wherein an insulating body (12), generally in the shape of a rectangular parallelepiped, no larger than a finger nail, holds a light-emitting diode (14) in the body at right-angles to the surface of a printed wiring board, the body being shaped such that robotic equipment can be used to mount the diode assembly cheaply and efficiently on the board. The body has front and back generally parallel surfaces, top and bottom generally parallel surfaces, and first and second generally parallel side surfaces, the respective surfaces having grooves and protuberances to allow the light-emitting diode (LED) to be fixedly mounted in the body, and the body to be inserted into a printed wiring board which can then be wave soldered without deleterious effects on the LED or supporting body. The bottom of the body has two oppositely faced snap-in protuberances (16) which pass through the hole on a printed wiring board, which deform inwardly slightly while passing through the hole and which resile after extending beyond the hole to fix the diode assembly in the correct position on the board.

Abstract in simplified Chinese:本发明之目的在提供一种能缩小半导体高度,使组件体积缩小之半导体封装。将在一边(本例中系右端)具有复数个略排成一排的电极4之半导体组件3装载于可折曲的挠性配线基板9上,而在只排列在封装的一边之外部连接用开口9b,安装外部连接用导电性构件之焊锡球13。如上述所构成之半导体封装8,借由折曲其挠性配线基板9即可相对于安装用基板7成水平或成倾斜之状态相连接。因此,可缩小半导体封装之安装高度H,以达成零件之小型化,减少安装面积及体积。
此外,也可在复数个半导体封装8间夹住散热机构15,而以互相倚靠之状态推倒而推叠,于此情形时,也能够抑低安装高度h。
Abstract:
PROBLEM TO BE SOLVED: To provide a high-power electrochemical DLC that may be mounted onto a PCB without hand soldering and without a prohibitive increase in ESR.SOLUTION: An electrochemical double layer capacitor (DLC) is configured for mounting on a PCB. A first connector component is configured at each individual terminal lead of the DLC capacitor. A second connector component is mounted on the PCB and includes a number of parallel connector elements at the mounted location for electrical mating contact with the DLC leads. The connector configuration produces a minimal increase in the ESR of the capacitor when mounted on the PCB.
