This is a market dataset, representing the consumption market of the region. The dataset includes transport from the gate to the point of consumption, and transport services are calculated based on the transport situation of this product in the region. The guiding needle of the capacitor is a conductive needle fixed inside the capacitor, used to connect with the capacitor's conductive plates, serving the function of forming capacitance between internal conductors of the capacitor. The average diameter of this guiding needle is 1.4 cm, and the average weight is approximately 0. 05g; This dataset includes the main raw materials, energy sources, and waste materials in the production process; manufacturing of production equipment, construction of workshops, and other infrastructures are not included within the boundary of the dataset; the data inventory is formed by merging data from multiple sources; the production of capacitor conductors includes mechanical stamneedleg, inspection, cleaning, dehydration, drying, and forming processes.
