The Importance of Quality Testing in Electronic Components

It is essential that an electronic component passes the testing stage if it is to be made for mass production. Using a system ensures that technical errors can be found and determines whether it meets quality compliance which reduces a customer’s risk of bringing a new product to market.

The user friendliness and reliability of a product usually depends upon how well the product was tested after the design stage. Quality testing professionals ensure that standards are met from the processing stage right through to the final release, ensuring that any defects are found as early as possible and any problems are solved.

The process involves analysing input data, then compiling test results and recommending changes to the Product Developers.

Testing Stages

  • Development tests – Quality testing can be performed before a product goes to market.
  • Software tests – This testing can ensure standards are met with error free operation, user friendliness and stability.
  • Prototype tests – This platform testing verifies stated specifications, evaluates workmanship quality and identifies any problems that could cause serious consequence after they go to market.
  • Production tests – Experts can develop tests to evaluate the level of quality control on the manufacturing floor. This includes manual and automated tests to determine the product’s functionality.
  • AGW test nearly all manufactured products using a 100% sample size.
  • Quality Testing - All test procedures are reviewed prior to their use by the Company as part of the Quality assurance system.

Testing also involves any inspections of outbound products leaving the factory. This will prevent any products leaving the factory which are defected and stop them from reaching the hands of the consumer.


We use sophisticated and automated methods where possible, utilising our Voltech automated test equipment.

During this year’s annual review, our management were made aware that certain pieces of test equipment required replacement. There followed an investigation into the type of equipment required and the best source for obtaining it.

After a series of meetings and research, the following equipment was obtained:

  • Uni-T Bench multimeter
  • Uni-T Hand multimeter
  • Hantek Oscilloscope
  • Wayne Kerr 3260G Precision magnetics analyser
  • Uni-T 500V insulation unit
  • Kust LM1010 Advanced LCR meter

The majority of the equipment came from known manufacturers, whose product AGW had used previously. This includes Wayne Kerr, who produce high quality analysers.

The unknown manufacturer was Kust, but thanks to their great service and very competitive pricing, we purchased the LCR meter. It has been in use for a few weeks and has been very impressive.

This new equipment, along with AGW’s existing equipment, keeps the Company’s testing facilities at a very high standard. At the peak of this high standard are the Voltech automated test stations and the Partial Discharge test equipment.

Electronic components pass quality assurance during the manufacturing stage and the product is tested at the end of manufacturing as a confirmation to companies that they can be assured of the quality of the product once it reaches the consumer.
