When the HDA and PCBA is then assembled into a single hard drive in the process of Final Assembly, as well as in the production of hard disk drives are also among other materials (other materials) and indirect materials. (indirect materials) used in all stages of the production of hard disk drives component fabrication to final assembly of other materials is not a major component parts such as screws, parts other metals. Or parts that can not tell if it was used as a component in the production process, either explicitly, while the indirect materials to be used in production, but not the parts in the assembly of hard disk drives, such as material. associated with various filter clean room gloves, shoes, mask work-related materials such as floor mats to reduce the charge for packing materials. And packaging, including the automation and building jig fixture to support the production of hard disk drives.
