ESD Surveys, Audits and Field Testing

ESD Surveys,
Audits and Field Testing

Independent, third-party auditing

Introduction

Cesstech provides services to ensure that materials and tools with your mini environment are “electrostatic-discharge-safe”.

Our team of experts use a wide range of equipment to facilitate extensive ESDC (Electrostatic Discharge Control) tests and measurements, which are supervised by independent, third-party iNARTE (National Association of Radio and Telecommunications Engineers)-qualified and -certified ESD technicians and engineers.

Benefits:

Independent 3rd party assessment
Development of test methodology / acceptance criteria/compliance verification plan
Problem identification and solution provision
Formal reports with recommendation
Conformance with industry recognised standards and protocols
Compliance with quality assurance guidelines within the facility
Facilitation of historical data compilation and trend analysis over time

Advantage:

Experience in a diversity of industrial sectors
Exemplary track record
All testing and studies supervised by qualified NEBB certified cleanroom testing supervisors
On-smiddle shop for performance testing and contamination studies
Comprehensive arsenal of equipment – both hardware and software
Trained technicians and engineers with relevant experience

Our services are designed to:

Develop a test methodology/acceptance criteria/compliance verification plan

Provide a formal evaluation and analysis of the ESD environment

Identify ESD susceptibility and failures
Deliver formal reports with recommendations
Give continual updates on standards/plans
Provide feedback and follow-up action plans
Deliver customised training programmes

Our ESD Testing Services

ESD materials/parts testing

We can test materials or parts like flooring, reticule pods, wafer carriers, ionizers, mats, garments, etc. for independent qualification purposes and in accordance with recognised ESDA standards.

These tests can be conducted either at our ISO Class 6 ESD safe facility or on-site at your premises.

ESD Audit

We can provide an audit designed to check and verify every aspect of your in-house and factory-wide ESDC programmes and ESD safe practices.

This audit includes surface charge/field potential/triboelectrification and resistance measurements (among others) on:

Tools
Direct/indirect materials
Workstations
Electrostatic protected areas (EPAs)
Floors
ESD garments
Mobile equipment
Shelving
Footwear, etc.

Monitoring & quantifying ESD events

We use ESD event monitors and software to evaluate the your cleanroom environment as part of your facility’s ESD compliance verification plan.

Appropriately place monitors can quickly detect and assess ESD events and we then provide our recommendations for remedial action.

Development and management of an ESD control programme

We can develop an ESD control programme for you based on the ESD susceptibility of the parts or products used at different stages of your manufacturing process. This involves:

Conducting a pre-audit where baseline measurements are made
Formulating the ESD control programme
Implementing the ESD control programme

Establishing compliance verification frequency, methodology and training

ESD training

We provide the following ESD training:

ESD Basics
Static Charge Control
Developing & Managing an ESD Control Programme
Theory/Fundamentals/Applications of Ionization
In-field ESD Testing & Auditing for operators, technicians and engineers.

The training includes hands-on practical exercises and a factory walk-through and can be delivered as a half-day or full-day seminar.

ESD testing of tools/mini-environments

We conduct ESD testing and verification of materials, work surfaces, transfer mechanisms, grounding, ionization and the general environment and enclosures of your facility.

Our tests encompass:

surface charge/field potential and triboelectrification examinations
resistance measurements
grounding checks
quantification of the number and magnitude of ESD events
electromagnetic field measurement
ionizer performance measurement, etc.

ESD compliance verification plan implementation

We will develop a compliance verification plan that will enable you to check and assess your ESD environment through periodic tests and measurements.

This plan will cover personnel, materials, production tools; storage and transfer mechanisms and components of a cleanroom environment, where applicable and will identify:

the type of tests to be carried out
the test equipment to be usedthe acceptance criteria and the frequency of testing

Ionization

We can evaluate and recommend ionizers for different applications in your individual environments.

Evaluations can include:

graphical plots of the offset voltages and rates of decay over time
the performance of the ionizers with feedback sensors/controllers and with different types/materials of emitter points
longer-term monitoring of defined parameters such as particle counts in a controlled cleanroom environment.
