S20.20 Overview

ANSI/ESD S 20.20 and ESD TR 20.20- Handbook

S20.20 Overview

• Applies to all activities from device level packaging to field service

• Level of control to 100 volts HBM

• Guidance provided for more sensitive parts and applications – (Handbook available from ESD

Association)

S20.20 Overview

A. All conductors in the environment, including personnel, must be bonded or electrically connected and attached to a known ground or contrived ground (as on shipboard or on aircraft).

S20.20 Overview

B. Assessment of the ESD hazard created by electrostatic charges on the necessary non-conductors in the work place is required.

S20.20 Overview

C. Transportation of ESDS items outside an Electrostatic Protected Area requires enclosure in static protective materials.

S20.20 Overview

• Evaluate your current ESD Control Procedures against industry standards

• Compare material specifications to current specifications

• Compare test methods and specifications to current test methods

Section 6: ESD Control Program Requirements and Guidance

Section 6.1: ESD Control Program Administrative Requirements

Section 6.2 ESD Control Program Technical Requirements

S20.20 Outline (Major Elements)

Administrative and Technical Elements

• Administrative and Technical Elements are contained within a properly written ESD Control Program Plan. The “Plan” contains the following Elements:– ESD Control Plan

– Training Plan

– Compliance Verification Plan

– Detailed Technical Elements

Compliance Verification Plan

• Identify the requirements that must be verified – Technical elements in the Plan

• Establish the frequency and type of verification that must occur (internal and external audits, certification etc.).

• Select appropriate test equipment based on industry standards.

Protected Areas

• Protected area design depends on application.• Area must be marked with proper signage.• Access to Protected Area limited to trained

personnel only. Untrained personnel must be escorted by trained personnel.

• Removal of all nonessential insulators required.• Ionization or charge mitigating techniques

required to neutralize charge on essential insulators if the charge level is considered a threat.

Packaging within EPA :

Required :

Low Charging

Dissipative

Protected Area Definition

• EPA (Electrostatic Protected Area):– A defined location with the necessary

materials, tools and equipment capable of controlling static electricity on all items entering or used within specified boundaries.

Packaging• ESD Protective Packaging and

package marking must be in accordance with customer requirements.

• If not defined by contract, purchase order, drawing or customer documentation, the Plan needs to define the protective packaging requirements.

Packaging

• Packaging shall be defined for all material movement within Protected areas, between job sites and within field service operations.

Packaging Considerations

• The type of packaging used depends on sensitivity of items and where the parts are going.– The intent of ESD protective packaging is to prevent a

direct electrostatic discharge from affecting packaged parts, allow for dissipation of charge from the package exterior, and minimize charging of the packaged items from external electrostatic fields and triboelectrification.

Implementing S20.20 in your Facility

• Get ANSI/ESD S20.20 (www.esda.org)• Document review to determine status• Write your own program according to

your applications• Incorporate changes• Train employees• Pre-Assessment Audit

What’s New in Certification?

• Add on to back of ISO 9000 audit• Some vendors/suppliers qualified

to do pre-assessment (based on experience)

• Additional Registrars coming on board

What’s New in Certification

• Authorized Registrars– Det Norske Veritas (DNV)

– BSi– QMI

– NQA– LRQA (Pending)

• (Watch the ESDA web site for new Registrars)

ESD S20.20

Earning Certification to S20.20• ISO 9000-2000 style

auditing• ISO Registrars conduct

audit• Certification granted by

Registrar and ESD Association

• Only ISO Registrar can certify

Program Manager Certification

• New initiative– ESDA Certification of individuals

that complete requirements– Prerequisite Tutorials

– Program Manager Review Course (4 hours) and Final Exam (4 hours)

Program Manager Certification

• Prerequisite Tutorials available this year:– How To’s of In-Plant ESD Survey &

Evaluation Measurements– Electrostatic Calculations for the ESD

Engineer– Air Ionization: Issues and Answers– ANSI/ESD S20.20 Seminar for

Independent Assessors, Program Managers, and Consultants (2 day course)

Program Manager Certification• Courses Available 2004:

– Packaging – Workstation Design– Revised Basics of Static Control– Revised Standards– SPC*– ESD Hazard and Risk Assessment *– Device Protection/Failure Analysis Basics– ISO9000-2000 Overview– Employee Training and Record Retention*– Program Manager Course and Final Exam* May be built into other Tutorials
