Description

Full-open steel plate with controllable thickness Technical Field The utility model relates to the technical field of steel plate printing, in particular to a full-open steel plate with controllable thickness. Background The full-open steel plate is a novel steel plate in the screen printing technology, and an opening area of the full-open steel plate directly penetrates through a material to form a fully-open channel for printing of conductive paste, so that a longer fine grid is formed on the surface of a battery piece at one time. The traditional full-open steel plate is made by laminating two metal layers, and the thickness of the formed full-open steel plate is very thin, so that the whole thickness cannot be accurately measured, the thickness measurement of a single-layer metal layer is more difficult, and the thickness of the single-layer metal layer cannot be accurately measured and controlled no matter the single-layer metal layer is manufactured by a manufacturer or a raw material manufacturer at present, so that the control of the printing high-precision requirement cannot be met. Therefore, there is a need for a full-open steel plate with controllable thickness that can measure the thickness of a single metal layer, improve measurement accuracy, and meet the requirements of printing with high precision.
