Checking the compliance of electronic components

​

This standard identifies the competences you need to carry out the checking and inspection of electronic components during or on completion of the manufacturing process, to ensure that they conform to specification, in accordance with approved procedures. You will be expected to review specifications to determine checks needed at various stages of manufacture, to establish compliance by making those checks and to report and record any significant variances. Your responsibilities will require you to comply with organisational policy and procedures for the post-production inspection and checking activities undertaken and to report any problems with the activities 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 the necessary checking and inspection procedures. You will know how to set up and use checking equipment effectively. You will understand the purpose of the checks and inspection points and their application and will know about the newly manufactured electronic products, in adequate depth to provide a sound basis for carrying out the activities, identifying faulty or out-of-specification components and taking the required action to correct this. You will understand the safety precautions required when working in the electronic component-processing environment and with the associated inspection equipment. You will be expected to know about any hazards associated with such checks and what precautions to take to minimise the risks involved. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.

​

1. work safely at all times, complying with health and safety legislation, regulations, directives and other relevant guidelines
2. follow instructions and specifications for checking products or assests
3. select,  obtain and the tools and inspection equipment and check that they are in useable condition
4. conduct compliance checks using an appropriate sequence, using approved methods and procedures
5. identify and assess any defects or variations from the specification and take appropriate action
6. deal promptly and effectively with problems within your control and report those that cannot be solved
7. ensure that work records are completed, stored securely and available to others, as per organisational requirements
8. leave the work area in a safe condition on completion of the activities, as per organisational and legal requirements

11. the types of defect that can be found on electronic components and why they occur (such as dimensional errors in electronic connectors and their housings, lack of plating thickness in critical areas)
12. how to identify manufacturing defects and what to do to rectify them
13. the factors to be considered when determining if a component should be scrapped or modified
14. the quality control procedures to be followed when checking the electronic component
15. the importance of ensuring that all tools and equipment are returned to their correct location on completion of the checking activities
