In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This Unit Standard is for persons who are expected to perform soldering in the working environment. This unit standard will provide learners with methods and procedures to perform soldering operations.

Learners credited with this Unit Standard are capable of:
  • Preparing for soldering.
  • Identifying and placing components on the PC board.
  • Perform soldering.
  • Coat and encapsulate the PC board. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are competent in:
  • Communication skills at NQF Level 3.
  • Computer literacy at NQF Level 3. 
    		•

    UNIT STANDARD RANGE 
    Soldering may refer to but is not limited to:
  • Wires and terminals.
  • Thru-hole mounting.
  • Surface mount technologies.

    Standards may include but are not limited to:
  • Set standards refer to the measurements conforming to the J-STD - 001standard with specific reference to: component preparation, lead forming, component placement, lead termination requirements, minimum and maximum solder requirements, coating and encapsulation. 
    		•

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Prepare for soldering. 

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    The solderability of the components is verified in order to determine durability and functionality of the total assembly. 

    ASSESSMENT CRITERION 2 
    Methods of verifying solderability are identified and explained to determine any contamination on the components leads. 
    ASSESSMENT CRITERION RANGE 
    Methods include but are not limited to visual and pre-tinning.
     

    ASSESSMENT CRITERION 3 
    Components are bent in accordance to set standards. 

    ASSESSMENT CRITERION 4 
    Component leads are pre-tinned to verify its solderability. 

    ASSESSMENT CRITERION 5 
    Soldering equipment is set at the correct temperature to ensure a secure joint. 

    ASSESSMENT CRITERION 6 
    The importance of cleaning the PC board is explained in order to ensure reliability of the solder joint. 

    ASSESSMENT CRITERION 7 
    Oxide and contamination are removed using a solvent to promote solderability of the connection. 

    SPECIFIC OUTCOME 2 
    Identify and place components on the PC board. 

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    Components for soldering are identified in terms of their functionality as determined by the circuit diagram. 

    ASSESSMENT CRITERION 2 
    Tools for placement are selected in accordance with the component chosen. 

    SPECIFIC OUTCOME 3 
    Perform soldering. 

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    An appropriate solder tip is selected to provide the correct amount of heat transfer. 

    ASSESSMENT CRITERION 2 
    The component is secured to the PC board in order to prevent movement in the solder joint whilst solidifying. 

    ASSESSMENT CRITERION 3 
    Flux is applied prior to soldering in order to clean the surface to be soldered and to act as an oxidisation barrier whilst the solder is molten. 

    ASSESSMENT CRITERION 4 
    Various methods of cleaning the completed assembly are identified in terms of their uses and relevance. 
    ASSESSMENT CRITERION RANGE 
    Various methods include but are not limited to solvent method and ultrasonic method. Ultrasonic method may not be used on sensitive electronic components.
     

    ASSESSMENT CRITERION 5 
    Methods of assessing the cleanliness of the assembly are identified and explained in terms of their uses. 
    ASSESSMENT CRITERION RANGE 
    Methods include but are not limited to ionic residue instrument method, ionic residue manual method and surface insulation resistance method.
     

    ASSESSMENT CRITERION 6 
    The solder connection is wetted in accordance with the set standard. 
    ASSESSMENT CRITERION RANGE 
    Set standard refers to not more than 90 degrees.
     


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • Anyone assessing a learner or moderating the assessment of a learner against this unit standard must be registered as an assessor with the relevant ETQA.
  • Any institution offering learning that will enable the achievement of this unit standard must be accredited as a provider with the relevant ETQA.
  • Assessment and moderation of assessment will be overseen by the relevant ETQA according to the ETQA`s policies and guidelines for assessment and moderation.
  • Moderation must include both internal and external moderation of assessments at exit points of the qualification, unless ETQA policies specify otherwise. Moderation should also encompass achievement of the competence described both in individual unit standard as well as the integrated competence described in the qualification. 
    		•

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    Learners should have a knowledge and understanding of:
  • Read data sheets.
  • Read the engineering drawing.
  • Demonstrate knowledge of Electric Static Discharge.
  • Able to identify components.
  • Polarity identification. 
    		•

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
