Purpose
This unit standard covers electrostatic discharge (ESD) control procedures in
an electronic manufacturing environment, designed to minimise electrostatic
damage to components.
People credited with this unit standard are able to:
– describe the cause, effect, and prevention of component damage by ESD
in electronic manufacturing; and
– use ESD control procedures in own workplace.

Elements and performance criteria
Element 1
Describe the cause, effect, and prevention of component damage by ESD in electronic
manufacturing.
Performance criteria
1.1
The generation of electrostatic charge on the body is described.
1.2
The damage arising from handling semiconducting components in the presence
of charge is described.
Range
permanent damage, latent damage, intermittent damage.
1.3
The effect of ESD damage on production and quality of products is described.
1.4
Methods to prevent ESD damage are identified.
Range
1.5
warning labels, protective materials, handling, safe workstations.
Electrostatic control procedures are described, and those used in own
workplace identified.
Range
control procedures – use of warning labels; minimise handling;
component packaging; discharging by contact with earthed
metalwork; grounded wrist straps; foot straps used with conductive
floor coating; grounded antistatic foot and bench mats.
Element 2
Use ESD control procedures in own workplace.
Performance criteria
2.1
Electrostatic discharge control procedures are used in own workplace in
accordance with company procedures.
Range
assessment by observation of use of procedures over a two-week
period.
Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated
authority for quality assurance, before they can report credits from assessment against
unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register
credits from assessment against unit standards.

Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for organisations
wishing to develop education and training programmes, such as minimum qualifications for
tutors and assessors, and special resource requirements.
