The purpose of this study was to develop a grid forming equipment of the electromagenetic interference(EMI) shielding sheet for use in a wireless charger. In addition, the present study was to form a lattice in the surface of the thin metal ribbon to exert an electromagnetic wave shielding performance of the precision small electronic devices such as smart phones. For this, grid forming presses such as manual pressurized press, automatic pressurized press, heat pressurized press, and continuous grid forming equipment with cylinder roll type, and a grid inspection and grid uniformity inspection devices have beendeveloped. Finally, the cylindrical roller-type continuous grid forming equipment showed the best suited.
