Unit Descriptor

Unit descriptor 

This unit covers soldering/desoldering for the installation and fabrication of electrical/electronic components to advanced or military specifications, or where the reliability of electrical connections is critical and where prevention of damage through electrostatic discharge or other means is required.

Application of the Unit

Application of the unit 

This unit has limited application and should be confined to work undertaken on equipment where continuous performance is critical and this may include work to military specifications.

It covers the soldering of electronic components where prevention of damage through electrostatic discharge or other means is required.

This unit can also cover the soldering of electronic Surface Mount Devices (SMD).

Work is undertaken in a workshop, laboratory or in situ.

All materials and procedures are determined from specifications, manufacturers' data sheets, standard operating procedures or in consultation with a technical expert.

All work is undertaken to legislative and regulatory requirements.

Precision electro-measurement is covered by other unit/s.

Hand and power tools and drawing interpretation skills may be required. These are covered by Unit MEM18001C (Use hand tools), Unit MEM18002B (Use power tools/hand held operations) and Unit MEM09002B (Interpret technical drawing).

Manual soldering for the installation and fabrication of electrical/electronic components, where reliability of connections is not critical, is covered by Unit MEM05001B (Perform manual soldering/desoldering - electrical/electronic components).

Evidence Guide

EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

A person who demonstrates competency in this unit must be able to solder/desolder for the installation and fabrication of electrical/electronic components to advanced or military specifications, or where the reliability of electrical connections is critical and where prevention of damage through electrostatic discharge or other means is required. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and to be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment 

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with performing high reliability soldering and desoldering or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment 

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment
