Computer Assembly Technician


Computer assembly technicians build computers from their parts, such as circuit boards, disk drives, cables and switches. When they've put the parts together, they test the computer and correct any faults.

Also known as

  • Assembly Technician, Computer

Work Activities

As a Computer Assembly Technician, you will build complete computers from their parts. For an ordinary personal computer, these would include:

  • external cases
  • power supply units
  • disk drives
  • processors
  • circuit boards
  • cooling fans
  • cables and switches

Computer Assembly Technicians gather the items they need. You will fit the parts and connect them up, then test that the finished computer is working correctly. If it's not working, you will do more tests to discover where the fault lies, and correct it.

If you work for a specialist supplier or retailer, you may build each machine according to a different set of specifications, as required by the customer.

In these cases, you may also deal with customers, and perhaps service and upgrade existing machines. Some also install software onto the computer.

You will also use tools such as screwdrivers and soldering irons, and electronic testing equipment such as oscilloscopes. Some of the parts used in computers are delicate and sensitive, so you may have to wear special clothing to reduce the risk of contamination by dust or dirt.

Also, static electricity can damage some circuit boards, so you may have to avoid wearing certain items, (for example, fabrics such as nylon) which can allow static to build up. You may also have to wear anti-static wristbands and other static-reducing items.

Being able to read, write and speak Welsh may be an advantage when you’re looking for work in Wales.

Personal Qualities and Skills

To become a Computer Assembly Technician, you need:

  • an interest in computers and electronics
  • good manual dexterity, as many of the parts are small and delicate
  • to be able to work reasonably quickly
  • a methodical approach and the ability to follow written instructions precisely
  • to be conscientious and careful, as mistakes made during assembly can be costly and time-consuming to put right later
  • patience and perseverance to find and fix problems
  • good communication skills, as well as a polite and helpful manner if dealing with customers
  • a reasonable level of physical fitness - you may have to carry heavy computers or parts to and from stockrooms and workshops
  • stamina to complete repetitive manual tasks such as soldering and inserting circuit boards
