Testing post-production electronic components and circuits

This standard identifies the competences you need to carry out post-production tests on electronic components or circuits, in accordance with approved procedures. You will be required to carry out all preliminary essentials, such as obtaining risk assessment/permits to work and following clean work area protocols where appropriate. In addition, you will be expected to review and check the currency of the testing requirements, to set up and prepare the testing facilities for use, to conduct prescribed tests, to consider the implications of results obtained and to record and report your findings.

Your responsibilities will require you to comply with organisational policy and procedures for the testing activities undertaken and to report any problems with these activities or with the tools and equipment used, that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking full responsibility for your own actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying test procedures for electronic components and circuits. You will understand the basic operating principles of the items being tested, their main parameters and their application, in adequate depth to provide a sound basis for carrying out the activities, recognising when circuits/components do not meet the required specification.

You will understand the safety precautions required when working in a test environment for electronic components and circuits and with the test equipment used. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.
