When new incoming material enter into STHL Electronics warehouse, quality departments staffs test the material using precision inspection instruments to verify the material is in satisfactory conditions. For customized materials, testing as per customers BOM list and datasheet is necessary. After the materials are approved, they are entered into a material management system, which prioritizes the material in a first-in-first-out method. The material management system can monitor the expiration dates of materials. As the expiration date nears, the systems will warn the system operator which ensures materials are used within their valid time.
