Overview
| This standard identifies the competences you need to carry out material finishing operations by electroless nickel plating methods, in accordance with approved procedures. You will be expected to confirm with the authorised person, such as your immediate supervisor, that the equipment is ready for the plating operations to be performed and that all the required components/materials and consumables are available. You will be required to operate the electroless nickel plating equipment, in line with safe working practices and approved procedures, continuously monitoring the plating operations and where necessary, making minor adjustments or seeking help from the authorised person to make the required adjustments, in order to ensure that the work output is to the required quality. Meeting production targets will be an important issue and your production records must show consistent and satisfactory performance. Your responsibilities will require you to comply with organisational policy and procedures for the electroless nickel plating activities undertaken and to report any problems with these activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work to instructions, with a minimum of supervision, taking personal responsibility for your actions and for the quality of the work that you carry out. Your underpinning knowledge will be sufficient to provide a sound basis for your work and will enable you to adopt an informed approach to applying electroless nickel plating procedures. You will have an understanding of the electroless nickel plating process and its application and will know about the equipment, materials and consumables in adequate depth to provide a sound background for carrying out the activities, recognising and reporting plating defects and ensuring that completed components are to the required specification. You will understand the safety precautions required when working with electroless nickel plating equipment and solutions. You will be required to demonstrate safe working practices throughout. You will also understand your responsibilities for safety and the importance of taking the necessary safeguards to protect yourself and others in the workplace. |
Performance criteria
You must be able to:
| 1. work safely at all times, complying with health and safety legislation, regulations, directives and other relevant guidelines 2. follow work instructions and specifications for electroless nickel plating 3. ensure the material surfaces to be treated are prepared for the finishing operations 4. check that the finishing equipment and treatment solutions are set up and maintained at satisfactory operating conditions and levels 5. carry out the treatment process following operating procedures and to meet the component specification 6. ensure that the treated workpiece achieves the required characteristics and meets the finishing specification 7. deal promptly and effectively with problems within your control and report those that cannot be solved 8. ensure that work records are completed, stored securely and available to others, as per organisational requirements 9. leave the work area in a safe condition on completion of the activities, as per organisational and legal requirements |
