rubber sheet should be used in the workshops and advanced adoratories for Microelectronic industries suchas electronic semi -conduct devices,computers, Tele-communication equipment and integrated circuits ect. To eliminate damagescaused by staticelectricity . When anti-static table pads (ground pads)are laid out and grounded,the working surface will discharge the static electricity of human bodies so that a near-equipotentialcan be maintained for ESDS tweezers , tools , utensils and instruments , through which human bodies contact the working table and static sensitive devices (SSD)are free from broad band interference produced by static discharging such astriboelectrification etc , in this way , electrostatic protection is reslized
