Investing in an EPA is important






        There are two types of ESD damage in industrial and   bear eyes and the product may pass all tests and function
        technical environments. Firstly, a fatal defect that is usually   normally for some time. However, latent damage affects the
        easily detected during assembly or handling, or at least   performance and durability of the product and and often
        through careful testing. Such products are usually not   results in poor product quality.

        damage is latent damage. This is difficult to detect with




        Static charge management of a working area:

        •  ESD-protected workstations. Attention paid to ESD safe storing, moving and packing.
        •  Personnel protected with shoes, wrist straps and other needed accessories

        •  Staff training, work instructions and quality control
        •  Cleanliness of ESD-protected equipment. Dust and dirt insulate.

        •  Commitment to continuous improvement in static electricity management
