GSFC Electrostatic Discharge (ESD) Control Program Are you plugged in? Jeannette Plante, Program Manager, Code 300

1. GSFC Electrostatic Discharge (ESD) Control Program Are you plugged in? Jeannette Plante, Program Manager, Code 300

2. An ESD event is a sudden discharge of stored voltage (charge) through a circuit path to ground. This event will damage sensitive circuitry. Failure may be instantaneous or delayed. Working conditions determine event type. Event type determines protection method. Source: White Paper 2: A Case for Lowering Component Level CDM ESD Specifications and Requirements, Industry Council on ESD Target Levels, March 2009

3. Protection Method Depends on ESD Event Types • Human Body (HBM): discharging event through the body and the part to ground. • Machine (MM): discharge voltage through automated handling equipment or hand-tools and the part to ground. • Charged Device (CDM): discharge into or out of a part due to charge accumulation within the part itself.

5. ESD Sensitivity Level Designations GSFC-WM-001 Uses HBM Class 1A as a default for certified EPAs. GSFC-WM-001 provides controls for HBM Class 0 if needed. Subject Matter Expert help should be sought for CDM protections Protections designed for HBM work for MM too. CDM does not correlate with the other models and is still evolving Avoid making “Class 0” a colloquial term for “super sensitive” This may prevent the right type of control methods from being used.

6. The goal is to: • Prevent charge accumulation • Triboelectric charging is avoided, electric fields are monitored and controlled. • Enable accumulated charge to discharge with a controlled, low current. • Dissipative materials are used to enable accumulated charges to readily find a “gentle” discharge path that keeps current low.

7. NASA Quality Assurance Program Policy (NPD 8730.5) ANSI/ESD S20.20 for ESD Control The Organization shall establish, document, implement, maintain and verify the compliance of the ESD Control Program in accordance with requirements of this document. GSFC Policy for Electrostatic Discharge Control (GPR 8730.6) GSFC-WM-001 is applicable to all organizations where ESD sensitive electronic components for flight applications, including engineering and test models, and Ground Support Systems, are tested, assembled, inspected, stored, or otherwise processed in a laboratory environment. In-house builds only GSFC-WM-001, Workmanship Manual for Electrostatic Discharge Control (Excluding Electrically Initiated Explosive Devices)

8. Where is GSFC-WM-001 ?!? It’s not in GDMS GSFC-WM-001 lives in the Code 300 configuration management system. An easy link to remember is: http://sma.gsfc.nasa.gov/workmanship/ Then click on Useful Links

9. GSFC-WM-001 addresses all areas covered in ANSI/ESD S20.20 considered to impact GSFC operations: • Shipping and receiving • Identifying ESD sensitivity (ESDS) level • Communicating ESDS level to affected personnel • The need for special, local procedures and training • ESD Protected Area (EPA) minimum controls • Personnel training and certification • EPA certification • EPA maintenance • Visitor control • Non-conformances • Verification measurement procedures

10. Branch/Division Role vs Project Role • Branch/Division • Provides certified personnel • Provides certified facilities • Maintains certified facilities • Provides equipment resources to EPA managers and users • Stores and re-uses ESD control equipment • Facilitates personnel mentoring and provides subject matter expertise • Provides procedures and local training as applicable. • Project • Flows down requirement • Covers cost of EPA resources (equipment, supplies, procedures) where need exceeds lab’s internal resources. • Establishes tolerance for risk, process requirement waivers as applicable • Defines impact of ESD damage and potential ESD damage

11. GSFC-WM-001 : Are You a Participant? • Program Manager: Manages program including ownership of GSFC-WM-001 and GPR 8730.6; certifies ESD protected areas (EPA) (Code 300) • Level A Trainer: Trains Operators, Program Monitors, Level B instructors. • EPA Certifier: Certifies EPAs (Code 300, 800) • Subject Matter Expert: Helps navigate non-standard conditions (Code 300, 500, 600). • Workmanship ---------------------------------------------------------- Branch Personnel • Lab Owner: Provides resources, assignments, points to correct training, accountable for all operations in labs • Program Monitor: Local owner of ESD protected area (EPA), designs and safeguards EPA, monthly verification measurements, special training, retraining biennially (Code 200, 500, 600) • Operator: Local user of an EPA, special training, retraining biennially (Code 200, 300, 400, 500, 600) • Level B Trainer: Trains personnel from their company or subcontractors • I&T ESD Lead: Defines control methods and procedures during I&T

12. Training GSFC School   http://www.honeywell.com/workmanship Operator: 4 hr class, overview, demonstrations [ESD] Program Monitor: 12 hr class, overview, hands-on exercises, demonstrations. Requiredfor Bench Certification Level B Instructor: 16 hr class, overview, hands-on exercises, demonstrations, instruction materials provided Lab Owners: 1 hr class, overview of program, roles and responsibilities I&T ESD Lead: in development Classes held on Center and in Columbia Instruction is to GSFC-WM-001

14. Laboratory Quality Improvement Team • Collaborative effort including Code 300, 400, 500, 600, 800 • Strengthening process ownership, consistency and compliance across all labs • Focus now is ESD, Calibration, Pressure Vessel Certification. Adding Lifting Devices, Workmanship • Assessing each lab on Center to: • educate lab owners about requirements • provide opportunity to correct before audit by internal or external auditors • Feedback to process technical authority (e.g. Workmanship group for ESD) • Project start was May 2011. Expect to take several years to visit each and every lab on Center. • Urgencies identified in the ESD area: • Lab owner awareness • Training effectiveness • Missing content in GSFC-WM-001 • Garment process not fully effective
