A document well worth reading is BS EN 100015 which covers just about everything possible regarding how one should protect Electrostatic Sensitive Devices. It has nine Sections, with Annexes and loads of Figures and Tables (see end of this message for details).
Its a comprehensive Standard, and following it to the letter is arduous - we have used it to generate our own in-house company Standard so I speak from experience. However, the principles it puts forward are only common sense in the end, and it's quite a practical, readable document. Our QA department (we're ISO9000) were very happy with our in-house engineer-written standard. I think the subjects of interest to you would be initial training of everyone who comes into contact with ESDSs (and regular follow-up training to remind them what they have forgotten) and the daily, weekly, monthly and six-monthly recorded checks on equipment and procedures. Weve hired training videos from Vermasons (Weston-super-Mare, England Tel: +44 (0) 1934 518777) and we buy all our wrist straps, chairs, mats and things from them as the bits all meet the limits of the BS EN standard. (I havent searched to see if they have a Web site Im afraid.) For your interest, the nine sections of BS EN 100015 are: General; Design consideration to minimise the effects of ESD; Labels signs and marking; ESD Protected Area (EPA); Protective packaging marking and identification for ESDS; Purchase, receipt, storage and handling; Training; Quality responsibilities; Periodic audit instructions Annexes: Test procedures; Surface resistivity and resistance to ground; Charge decay; Measurement of antistatic properties; Additional tests; Measurement of relative humidity. Figures: ESDS basic symbol ; ESDS simplified symbol ; Warning label for ESDS ; Warning sign for ESD protected area ; Examples of ESD earth facility labels ; Examples of earth bonding point labels ; Examples of earth grounding point labels ; Schematic of typical EPA ; Example of an EPA showing typical facilities ; Fieldwork implementation of EPA ; Fieldwork implementation of EPA with bench ; Charge measuring equipment ; Capacitive sensor; Electrostatic shielding test equipment). Tables: User guide chart resistance, resistivity and charge decay in ESD protected areas; User guide chart for packaging materials; Suggested format for report. Hope thats of help!
