Application

This unit of competency defines the skills and knowledge required to locate faults in digital electronic equipment or sub-assemblies and replace faulty components.

Where soldering of components is required to advanced or military specifications, where the reliability of electrical connections is critical, or where surface mounted devices are being soldered/de-soldered then unit MEM05002 Perform high reliability soldering and desoldering should also be selected.

Where termination of cables is required unit MEM10002 Terminate and connect electrical wiring and unit MEM18063 Terminate signal and data cables, should also be selected as appropriate.

Where the selection and use of engineering measurement is required unit MEM12023 Perform engineering measurements should also be selected.

Where the selection and use of power tools/hand held operations is required unit MEM18002 Use power tools/hand held operations should also be selected.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

  • 3.3 Refit repaired/replacement components
  • 3.4 Refit repaired equipment to system
  • 3.5 Check and test systems/equipment for compliance with specifications using appropriate test procedures and equipment

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying and interpreting equipment specifications, manuals, circuit and schematic diagrams, maintenance records and supplier catalogues and obtaining relevant data with respect to diagnosing and repairing digital equipment and components

checking electronic equipment/sub-assemblies, components, connections and terminations for compliance to specifications

locating, reading/recording and diagnosing built-in fault indicators and obtaining error code interpretation documents and running test functions and recording faults and/or equipment status indicated by built-in test functions/displays

checking and testing equipment using appropriate test equipment and fault-finding techniques for compliance to specifications

reproducing fault symptoms in the electronic equipment and verifying faults using appropriate test equipment and fault-finding techniques to locate and isolate faulty component or fault cause

removing and replacing faulty components from the electronic equipment

adjusting/tuning, calibrating and testing the repaired electronic equipment/sub-assemblies to specifications

returning the repaired equipment and components to service in accordance with SOPs.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

implications of electro-static discharge (ESD) upon the electronic equipment

analog and digital electronics, including amplifiers, oscillators, power suppliers, filters, transistors, ICs, digital timers, gate arrays, transmitters and converters

function(s) of the electronic equipment/sub-assembly

procedures for:

running built-in test functions

verifying faults in electronic equipment/sub-assemblies

isolating electronic equipment/sub-assemblies

removing sub-assemblies from electronic equipment

testing faulty sub-assemblies

removing and repairing/replacing faulty components from electronic equipment

fitting repaired/replaced components into sub-assemblies and sub-assemblies into electronic equipment

testing electronic equipment/sub-assembly performance

errors indicated by built-in devices

symptoms of the fault in the electronic equipment/sub-assembly and purpose of reproducing fault symptoms

test equipment and techniques necessary to confirm electronic equipment/sub-assembly faults

tools and techniques to be used to remove/refit/repair/replace the faulty sub-assemblies/component from the electronic equipment

operational specifications of the sub-assembly

equipment and techniques to be used to test the faulty sub-assemblies/component and probable causes of component failure

operational specifications of the electronic equipment/sub-assembly/component

test equipment and techniques necessary to check electronic equipment/sub-assembly performance.

Assessment Conditions

Assessors must:

have vocational competency in diagnosing and repairing digital equipment and components at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Foundation Skills

  • text: This section describes those required skills (reading, writing, oral communication and numeracy) that are essential to workplace performance in this unit of competency. Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
