SHADOW MASK SUPPORTING APPARATUS FOR MAGNETIC FORCE VACUUM DEPOSITION

摘要

PURPOSE: A shadow mask supporting apparatus for magnetic force vacuum deposition is provided to get an accurate circuit pattern by using magnetic force to support closely shadow mask at glass. CONSTITUTION: An upper plate(11) and a support plate(15) faces each other and is separated a designated interval. A several magnetic force generating part(53), which is wound with a coil(49), is inserted between the upper plate(11) and the support plate(15). The upper plate(11) and the support plate(15) have a same plane shape, and a support member(25) supplies inside space to the edge part. The support member(25) has a shape of the edge of the upper plate(11) or the support plate(15), and is formed vertically with a several bolt hole(31) and an installation opening(27). The support member(25) has a designated height, and combines the upper plate(11) and the support(15) to be separated with parallel and a designate interval, and then supports a magnetic force generator(53) strongly.
