Waste straight plate mobile phones come from candy bar phones that are scrapped during consumption (not for reuse or remanufacturing of the whole machine), and the screen size is less than 2.5 inches. The process represented in this dataset is that after entering the dismantling workshop, the waste straight plate mobile phone is decomposed using manual and mechanical physical processes to form dismantling products such as materials or parts, and manual disassembly uses manual, pneumatic, and power tools to dismantle all components or parts that can be directly removed (excluding accessories such as chargers, power cables, and headphones).
