Specifications for conduct of

ESD audit of laboratories at URSC and ISITE

1 ESD Audit

Implementation of an Electrostatic Discharge (ESD) Control Program is

essential for onboard activity that stores, assembles, transport, tests electronic

parts, assemblies and equipment susceptible to damage by static electricity. As

certain ESD damages hidden in nature and are not immediately visible through

performance of the device which may pop at later stages poses greater risk.

Workmanship standard for fabrication of Electronic packages (ISRO-PAX-300) list

out the implementation and maintenance methodology for ESD safe

fabrication/testing/handling area. RQEG Conducts audit labs for the verification of

effectiveness of this control program implemented/practiced at each labs and bring

out report on compliance, which is used for monitoring and control of Electrostatic

Discharge Control Program at URSC.

ESD control at URSC is exercised at three levels.

1.1 Primary control

Personal grounding

Grouping of work surfaces and equipments

Purge of Electric hazardous materials

Protective packaging

1.2 Secondary control

Conductive flooring

Special garments

Selective ionization

Antistatic treatment

Training, audits, procedures and awareness

1.3 Tertiary control

Humidity control

Work station ionization

Disciplinary materials

2 Work location, nature, period and quantity of audits

Subsystems Quality Assurance Group is looking for professional teams who

has the knowledge in ESD audit activities to cater the need for auditing around 75

P a g e | 2

labs located at URSC and ISITE Bangalore. Each audit is expected to be around

five weeks span for a four member team. One engineer from Systems Reliability

Group will be accompanying the team for the co-ordination and smooth conduct of

audit activities. Audit is required to be carried out once in every 6 months and total

number audit events for a period of two years will be four (4). Therefore, total

number of Labs to be audited for a period of two years to be 340 Nos (85 x 4). List

of labs to audited is listed in Annexure-1. Apart from above, approximately 24

surprise lab audits are to be conducted during the period of two years. Surprise

audits are to be carried out when prompted by RQEG with list of labs to be surprise

audited. All the 24 audits not necessarily be exercised in full quantity. However,

number of labs to be surprise audited at a time will be minimum three numbers.

3 Types of equipments to be handled

following measuring equipment and shall be brought by the service provider for the

audit along with report compiling laptop
