摘要:
The present invention relates to a card reader assembly. The card reader assembly can be mounted in a variety of vending equipment, arcade game equipment, and other suitable equipment. Furthermore, the card reader assembly can be mounted in a standard size vending machine bill validator opening.The card reader assembly can provide for the optional mounting of a card reader, a card reader interface circuit board, a payment module board, a communication board, and or a printer. The printer mechanism is mounted on a printer bracket. The printer bracket can be slid over the edges of and fastened to the support bracket. A paper exit slot can be provided in the card reader assembly faceplate to allow the printer paper to exit through the faceplate such that a user can receive the printer paper.In addition, the printer mechanism, card reader, and or a pushbutton can be electrically connected to the card reader interface board. The card reader interface board can be electrically connected to a computing platform 802, vending interface unit (system 500), or other suitable data processing device. In addition, a plurality of light emitting diodes (LED) can be incorporated into the card reader assembly. The LED display can be viewable by a user of the card reader assembly.
摘要:
A crack stop for low K dielectric materials of an integrated circuit (IC) formed on an IC chip using metal interconnects which do not form a self-passivating oxide layer, such as copper or silver interconnects, in a low-K dielectric material to prevent damage to the active area of the IC chip caused by chipping and cracking formed along peripheral edges of the IC chip during a dicing operation. A moisture barrier or edge seal is formed as a metal stack positioned along the outer peripheral edges of the active area of the IC chip. The crack stop is formed by at least one trench or groove positioned outside of the moisture barrier/edge seal on the outer periphery of the IC chip.
