Transfer printing apparatus for mask pattern and mask pattern preparation method

摘要

The present invention discloses a mask pattern transferring device and a method of preparing a mask pattern transferring device. The mask pattern transferring device comprises: a magnetization head disposed on a magnetization head carrying device, for magnetizing composite powders each comprising a core of ferromagnetic metal and an outer resin film; a rotary roller formed of a non-ferromagnetic material, for adsorbing the composite powders magnetized by the magnetization head; a demagnetization head disposed at a downstream of the magnetization head in the rotating direction of the rotary roller, for demagnetizing the magnetized composite powders adsorbed by the rotary roller; and a collecting container, the outer edge of which is tangent with one side of the rotary roller, and which is disposed at the downstream of the magnetization head along the periphery of the rotary roller to collect the demagnetized composite powders.

1. A mask pattern transferring device, comprising:
a magnetization head disposed on a magnetization head carrying device, for magnetizing composite powder, each particle of the composite powder comprising a core of ferromagnetic metal and an outer resin film; a rotary roller formed of a non-ferromagnetic material, for adsorbing the composite powder magnetized by the magnetization head; a demagnetization head disposed downstream the magnetization head in a rotating direction of the rotary roller, for demagnetizing the magnetized composite powder adsorbed by the rotary roller; and a collecting container, an outer edge of which is tangent with the rotary roller, and which is disposed downstream the magnetization head along a periphery of the rotary roller to collect the demagnetized composite powder, wherein the mask pattern transferring device further comprises a spray device disposed below the collecting container, for spraying a material, which improves the capability of the magnetized composite powder to be adsorbed onto the rotary roller, onto a part of the rotary roller between a lower outer edge of the collecting container and the magnetization head.
