??First,the basic principles of electrostatic protection
??a,inhibit the accumulation of static charge;b,quickly,safely and effectively eliminate the static charge that has been generated.
??Second,anti-static work area venue
??1.Ground material a.It is forbidden to directly use wooden floor or laying wool,linen,chemical fiber carpet and ordinary floor leather.b.The ground made of electrostatic conductor material,such as anti-static raised floor or anti-static mat on ordinary ground,should be selected and effectively grounded.c.It is allowed to use specially treated terrazzo floor,such as laying ground wire,carburizing or spraying antistatic agent on the ground.
??2,grounding a,anti-static system must have independent and reliable grounding device,the grounding resistance should generally be less than 10Ω,the embedding and testing methods should meet the requirements of GBJ 97.b.The anti-static ground wire shall not be connected to the power supply neutral line and shall not be shared with the lightning protection ground wire.c.Use three-phase five-wire system to supply power,and its ground wire can be used as anti-static ground wire(but the neutral wire and ground wire must not be mixed).d.The cross-sectional area of??the grounding main line shall not be less than 100mm2;the cross-sectional area of??the trunk line shall be not less than 6mm2;the grounding line of equipment and workbench shall be a multi-strand plastic coated wire with a cross-sectional area of??not less than 1.25mm2,and the color of the grounding wire shall be yellow-green It is appropriate.e.The connection method of the grounding main line should be brazed.f.Anti-static equipment connection terminals should ensure reliable contact,easy to install and disassemble,and allow the use of various clip-on connectors,such as squid clips and plug sockets.
??3,ceiling material ceiling material should use anti-static material products,under normal circumstances,the use of gypsum board products,the use of ordinary plastic products is prohibited.
??4,wall fabrics Wall fabrics should use anti-static wallpaper,under normal circumstances,it is allowed to use gypsum paint or lime paint wall,it is forbidden to use ordinary
??Wallpaper and plastic wallpaper.
??5.Humidity control a.The relative humidity of the anti-static working area should be no less than 50%.b.Allow the use of humidification equipment to spray the preparation or water to increase the ambient humidity without adversely affecting the product.c.The humidity of the computer room should comply with the relevant regulations in GB 2887,and similar computer rooms should also comply with this regulation.
??6.Regional boundaries The anti-static work area shall indicate the regional boundaries,and the warning signs shall be hoisted at obvious places.The warning signs shall comply with the provisions of GJB1649,and the ionized air air bath equipment shall be arranged at the entrance of the work area.
