Reclamation of Polymer PET Substrate Using T-Form Tool
In the current study, a reclamation module uses micro electroetching as a precision fabrication with a new design of T-form tool to remove the defective Indium-tin-oxide (TCO) nanostructure from the optical PET surfaces of digital paper display is presented in current studies. The adopted precision reclamation process requires only a short period of time to remove the TCO nanostructure easily and cleanly is based on technical and economical considerations and is highly efficient. A large rotational diameter of the cathode accompanied by a small gap width between the cathode and the workpiece corresponds to a higher removal rate for the TCO nanostructure. A small thickness of the electrodes, or a small edge radius of the electrodes takes less time for the same amount of TCO removal. A higher feed rate of the optical PET diaphragm combines with enough electric power to drive fast etching rate. High rotational speed of the T-form tool can improve the effect of dregs discharge and is advantageous to associate with the fast feed rate of the workpiece (optical PET diaphragm).
