防静电工作表面：发展和历史（一）

ESD Work Surfaces：Developments and History（1）

这篇文章对防静电工作台的发展和历史进行了回顾。静电放电工作台由支撑结构和被设计成经由接地导体使静电电荷消散的一个专门的薄层工作表面组成。防静电工作表面已成为防止静电损坏的第一道防线。这篇文章描述的工作表面发展历史与ESD市场和技术总的增长是并行发展的。当代工作台材料的历史开始于20世纪80年代早期薄板制品铝层的引入。此后不久，具有特殊表面电导率的高压三聚氰胺薄片投入使用。

This article reviews electrostatic discharge （ESD） developments and the history of ESD workbenches. ESD grade workbenches are composed of the supporting structure and a specialized laminated work surface that has been designed to dissipate static charges via conduction to ground. These specialized work surfaces have become an essential primary line of defense against ESD damage. The developmental history of work surfaces described in this article parallels the overall growth of the ESD market and technology growth. The history of current workbench materials began in the early 1980s with the introduction of aluminum layers in laminates. Shortly thereafter, high pressure melamine laminates with specific surface conductivity became available. The introduction of new testing requirements covering low humidity conditions （ESD STM 4.11-1999 and program standard ANSI/ESD S20.20-1999）has created the need for laminates that perform at low humidity.
