Monitoring and analysing data from electronic circuit manufacturing processes
Overview
This standard identifies the competences you need to monitor and analyse data from manufacturing processes associated with the fabrication and assembly of electronic circuitry, based on printed board, thick, thin or flexible film technologies, in accordance with approved procedures. In particular, you will be expected to satisfy a range of generalised activity support requirements, such as observing permit-to-work procedures, following any clean work area protocols, selecting and using suitable analytical tools, recording data and preparing reports.
You will be expected to use approved organisational procedures to monitor, collect, analyse and report on your interpreted findings from at least one of the areas of circuitry processing activity outlined. You will also be expected to produce reports of your monitoring and analysis of data (which may include functional D°, process yield, process capability (Cpk), cycle time), which was collected using appropriate tools and methods (such as statistical process control (SPC) and failure mode and effect analysis (FMEA)).
Your responsibilities will require you to comply with organisational policy and procedures for the monitoring and analysing of electronics manufacturing activities 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 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 data monitoring and analysis procedures. You will understand the organisational needs for such data and will know about the relevant circuit processing techniques, in adequate depth to provide a sound basis for carrying out the activities to the required specification.
You will understand the safety precautions required when working in an electronic circuit manufacturing environment and with the associated equipment. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.
Performance criteria
You must be able to:
- work safely at all times, complying with health and safety legislation, regulations, directives and other relevant guidelines
- ensure test data on which to conduct the analysis is available
- resolve any inconsistencies in the data
- analyse the data using approved methods and procedures
- check that the data analysis is accurate and thorough and takes account of the test conditions
- compare the analysis against the product or asset specification and identify any faults or variations from specification
- deal promptly and effectively with problems within your control and report those that cannot be solved
- ensure that work records are completed, stored securely and available to others, as per organisational requirements
- leave the work area in a safe condition on completion of the activities, as per organisational and legal requirements
Knowledge and Understanding
You need to know and understand:
- the specific safety precautions to be taken whilst carrying out the activities (including any specific legislation, regulations or codes of practice relating to the activities, equipment or materials)
- the health and safety requirements of the work area and the activities, and the responsibility these requirements place on you
- the hazards associated with the activities (including voltages ranges), and how to minimise them and reduce risks
- the personal protective equipment and clothing (PPE) to be worn during the activities
- voltage ranges, what constitutes a hazardous voltage and how to reduce the risks of a phase to earth shock
- how to obtain and use specifications for the product, assets or processes being monitored/analysed
- how circuitry and its features are specified and the limitations of the different types of materials used
- the basic operation of the associated processes and process equipment and how they relate to the particular area of the process being monitored and analysed
- the problems that can arise in the processing of the types of circuitry involved
- the monitoring/analysis tools, methods and techniques used by the organisation for the relevant work and how to implement them in the given work areas (such as FMEA, Cpk measures, function D°, process yield, cycle times )
- the terms and how to calculate mean, median, mode, standard deviation, range and variance
- how to calculate process capability (Cp and Cpk)
- the meaning of a failure mode, failure effect or failure cause
- the rating scale used in potential failure modes and effects projects, to include the severity rating scale, the occurrence rating scale and the detection rating scale
- how to calculate and use risk priority numbers (RPN)
- how to carry out a design of experiment project and the tools and techniques used
- where to obtain the data required to carry out the design of experiment
- how to calculate the sample size to be used in the design of experiment
what is meant by Alpha risk and Beta risk
the problems that can occur with the monitoring and analysis activities and how they can be avoided
- the formats for recording and preparing reports for the relevant categories of data being monitored/analysed and the levels of detail required including handover and batch control
- suitable methods for data presentation (such as in tables, charts, graphically)
- how to obtain the authority to enter the relevant work areas and any specific permit-to-work procedures that are used
- the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
- how to access, use and maintain information to comply with organisational requirements and legislation
