ESD防静电手册

5.4.4.4 According to products requirements for ESD, in order to prevent electrostatic the accumulation of equipment and people from reaching the potential danger level, Flex uses the anti-static floor in the anti-static related production areas; in order to eliminate static electricity effectively, Flex grounds equipments which generate electrostatic.

根据客户和产品的防静电要求，为防止积聚在设备和人身上的静电荷达到危险电位，在防静电相关生产区域采用了防静电地坪的方式；为简单有效地消除静电所产生的危害，对所有会产生静电的设备采取可靠接地的方式。

5.4.4.5 Networks of copper wires were designed in the material of anti-static floors and buildings. All metal networks connect and form a static electrical conduction pathway, so that the electrostatic can be released quickly and effectively to the earth following the static electrical pathway and grounding fittings underground.

在防静电地坪的防护材料和在防静电地坪所在空间的建筑物内，设计有铜线构成的网络，所有金属网络彼此连接形成静电传导的电气通路，使静电通过这些电气通路最终流向建筑物的地下接地装置，达到快速有效释放静电的目的.

5.4.4.6 ESD Ground System is a grounding system for Electro Static Discharge, which is independent in existence and function of AC (Alternating Current) System from system design to operation. All ESD equipotential points in each building should connect to ESD Ground System, not AC (Alternating Current) System.

从设计到最终使用, 防静电接地系统和交流 (AC)接地系统是两个独立的系统, 不能共用.各厂房所有的防静电等电势接地点要接入这个防静电接地系统内.

5.4.4.7 Design, Construction & Acceptance of ESD Grounding System: 防静电接地系统的设计、建设和验收：

Flex entrusted with reliable quality of design and construction companies, to complete the design, construction, supervision and final acceptance, according to the relevant national and international standards for ESD Grounding System. 委托具有可靠资质的设计和建设公司，根据防静电相关的国家标准和国际标准，进行设计、监督建设，并完成最终验收。

5.4.4.8 FE is responsible for monitoring and maintaining ESD main ground pole (once per six months), ESD ground trunk (once per six months), then record the result.

If there are out of control, FE should check if the joints are loose and tighten to ensure the ESD ground system is normal.

FE 负责监测和维护各厂房防静电接地系统, 其中对防静电主接地极和干线网络, 每半年检测一次, 并记录监测结果. 当监测结果超出标准范围时, 应检查连接处是否松散并紧固以确保防静电接地正常。

5.4.5.3 Supplier requirements 供应商要求

5.4.5.3.1 Sample qualification is required if new vendor is phased in or the ESD floor material is changed, FE, QA and relative department will join the audit process.

当引入新的供应商或者供应商的ESD 材料变更时需要做样品认证时FE ，QA 以及更多相关部门 将参与供应商的审核。

5.4.5.3.2 ESD supplier should warrant that the ESD floor will be maintained their usefulness within 12 month from the installation day. FE and QA will track the quality in the required period. Once the ESD floor testing result is out of acceptance limit, supplier

must replace the ESD floor material in time.

供应商必须保证地板在自安装完成之日起12 个月之内静电防护功能依然有效。FE 和QA将在此12 个月内跟进地板的质量情况。一旦出现检测数据超标 ,供应商将立即更换所有不符合的地板。

5.4.5.4 ESD Floor Qualification requirements /防静电地板的认证要求

5.4.5.4.1Facility Department colleague should notice QA auditor to qualify the status after the ESD floor has been installed.
