Personality Type

  • Conventional / Realistic

Knowledge

  • Circuit diagrams

    Read and comprehend circuit diagrams showing the connections between the devices, such as power and signal connections.

  • Electronic equipment standards

    The national and international quality and safety standards and regulations with regards to the use and manufacture of electronic equipment and its components, such as semiconductors and printed circuit boards.

  • Electronics

    The functioning of electronic circuit boards, processors, chips, and computer hardware and software, including programming and applications. Apply this knowledge to ensure electronic equipment runs smoothly.

  • In-circuit test

    Test to assess the correct manufacture of printed circuit boards (PCB). The in-circuit test (ICT) tests for shorts, resistance, and capacitance, and can be performed with a "bed of nails" tester or with a fixtureless in-circuit test (FICT).

  • Printed circuit boards

    Printed circuit boards (PCB) are essential components to almost all electronic devices. They consist of thin wafers or substrates on which electronic components, such as microchips, are placed. The electronic components are electrically connected through conductive tracks and pads.

  • Quality assurance procedures

    The procedures to inspect a product or system to ensure that it is according to specifications and requirements.

  • Instrument performance elements

    Elements that indicate or influence instrument performance. A first indication of the performance of the instrument is the accuracy or precision of the instrument, such as its response time, resolution, and range. A second indication of performance is the technical performance of the instrument, such as its power level, the electromagnetic interference, and transient voltages. A third indication of performance are environmental factors that can influence instrument performance, such as humidity, operating temperatures, or dust.

  • Printed circuit boards testing methods

    Printed circuit board (PCB) testing methods consist of those processes in which PCB components or systems are tested, such as the in-circuit test (ICT), joint test action group (JTAG) test, and automated optical inspection (AOI).

  • Integrated circuits

    Electronic components, made up from a set of electronic circuits which are placed on semiconductor material, such as silicon. Integrated circuits (IC) can hold billions of electronic components on a microscale and are one of basic components of electronic devices.

Skills

  • Communicate test results to other departments

    Communicate testing information such as testing schedules, samples testing statistics and test results, to the relevant departments.

  • Abide by regulations on banned materials

    Comply with regulations banning heavy metals in solder, flame retardants in plastics, and phthalate plasticisers in plastics and wiring harness insulations, under EU RoHS/WEEE Directives and China RoHS legislation.

  • Read standard blueprints

    Read and comprehend standard blueprints, machine, and process drawings.

  • Read assembly drawings

    Read and interpret drawings listing all the parts and subassemblies of a certain product. The drawing identifies the different components and materials and provides instructions on how to assemble a product.

  • Send faulty equipment back to assembly line

    Send equipment that didn't pass inspection back to the assembly line for re-assembly.

  • Ensure conformity to specifications

    Ensure that the assembled products are conform to the specifications given.

  • Measure electrical characteristics

    Measure voltage, current, resistance or other electrical characteristics by using electrical measuring equipment such as multimeters, voltmeters, and ammeters.

  • Ensure material compliance

    Ensure that the materials provided by suppliers comply with the specified requirements.

  • Process customer requests based on the REACh Regulation 1907 2006

    Reply to private consumer requests according to REACh Regulation 1907/2006 whereby chemical Substances of Very High Concern (SVHC) should be minimal. Advise customers on how to proceed and protect themselves if the presence of SVHC is higher than expected.

  • Meet deadlines

    Ensure operative processes are finished at a previously agreed-upon time.

  • Test printed circuit boards

    Test the printed circuit board with special testing adapters to ensure optimal efficiency, functionality, and that everything works according to design. Adapt the testing devices to the type of circuit board.

  • Perform in-circuit test

    Conduct in-circuit test (ICT) to assess whether the printed circuit boards (PCB) were correctly manufactured. The ICT tests for shorts, resistance, and capacitance, and can be performed with a "bed of nails" tester or with a fixtureless in-circuit test (FICT).

  • Check for solder defects

    Check the printed circuit board for solder defects and make adjustments as required.
