Personality Type

  • Realistic / Conventional


  • Circuit diagrams

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

  • Surface-mount technology

    Surface-mount technology or SMT is a method where the electronic components are placed on the surface of the printed circuit board. SMT components attached in this way are usually sensitive, small components such as resistors, transistors, diodes, and integrated circuits.

  • 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.

  • 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.


  • Prepare board for soldering

    Prepare the loaded printed circuit boards for solder operations. Clean the board and mark designated areas.

  • 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.

  • Read standard blueprints

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

  • Ensure conformity to specifications

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

  • Coat printed circuit board

    Add a protective layer of coating to the finished printed circuit board.

  • Solder components onto electronic board

    Solder electronic components onto bare electronic boards to create loaded electronic boards using hand soldering tools or soldering machinery.

  • Operate SMT placement equipment

    Operate surface-mount technology (SMT) machines and equipment to place and solder surface-mount devices (SMD) onto the printed circuit board with high precision.

  • Clean printed circuit board

    Clean the printed circuit boards and components as necessary before, during, and after the assembly process.

  • Monitor machine operations

    Observing machine operations and evaluating product quality thereby ensuring conformity to standards.

  • Assemble printed circuit boards

    Attach electronic components to the printed circuit board through applying soldering techniques. Electronic components are placed in holes in through-hole assembly (THT), or are placed on the surface of PCB in surface-mount assembly (SMT).

  • Ensure public safety and security

    Implement the relevant procedures, strategies and use the proper equipment to promote local or national security activities for the protection of data, people, institutions, and property.
