Abstract
The ink for printing an antenna pattern for a mobile phone according to an embodiment of the present invention includes a mixture of one of silver (Ag) powder, nickel (Ni) powder, copper (Cu) powder, and gold (Au) powder, liquid acrylonitrile, liquid polystyrene, liquid butadiene, and methyl ethyl ketone (MEK) as a diluent. The present invention does not include a plating process, and thus allows a significant improvement in productivity.
Claims23
An ink for printing an antenna pattern for a mobile phone, the ink comprising a mixture of conductive powder, liquid acrylonitrile, liquid polystyrene, liquid butadiene, and methyl ethyl ketone (MEK) as a diluent.
A method of manufacturing a plastic part for a mobile phone having an antenna pattern printed using conductive ink, the method comprising:
- a pad transfer step of attaching the conductive ink on a print pad in a form of an antenna pattern to be printed;
- a heating step of heating the print pad having passed through the pad transfer step;
- an ionizing step of ionizing a plastic part on which the antenna pattern is to be printed by emitting electrons with high voltage;
- a pattern printing step of printing an antenna pattern onto a surface of the plastic part for the mobile phone by pressing the print pad having passed through the ionizing step onto the surface of the plastic part for the mobile phone;
- and
- a drying step of heating and drying the plastic part for the mobile phone having passed through the pattern printing step.
