本文介绍一种集成电路器件用的保护罩。这种保护罩可以卡在扁平式集成电路器件上,使两边的引出线短路,从而防止集成电路器件在运输、安装过程中遭受静电损坏,或总测前的其他损坏。平时保护罩总是卡在集成电路器件上,只有在弯曲引出线或测试时才揭去保护罩。这种保护罩最初是美国宇航局为宇宙飞船上的扁平式集成电路器件研制的,但是这种设计也适用于其他形式的器件。
This article describes a protective cover for integrated circuit devices. Such a shield can be snapped onto a flat integrated circuit device to short out the leads on both sides, thereby preventing damage to the integrated circuit device from static electricity during shipping or installation, or other pre-test damage. Protective cover is usually stuck in the integrated circuit device, and only when the bending leads or testing to remove the protective cover. This protective cover was originally developed by NASA for flat ICs on spacecraft, but this design also applies to other forms of devices.
