KR970073257A - Stretcher for screen printing of printed circuit boards - Google Patents

Abstract

The present invention relates to a screen printing plate stretcher for improving the uniformity and process efficiency of a frame and a screen by providing a separator on a fixing plate for fixing the screen independently on four sides.

The present invention relates to a printed circuit board comprising two pairs of upper and lower support portions, each of which is composed of two long axes and one short axis fixing frame so that the screen having an area capable of being adhered to at least two or more frames is independently fixed at four sides A screen plate stitcher according to any one of claims 1 to 3, wherein a separator for placing the screen uniformly close to the entire upper surface of one of opposite sides of adjacent two side frames positioned in parallel between the adjacent frame and the frame, Respectively.

Therefore, according to the present invention, work efficiency is improved, productivity is increased, the defect rate is reduced by uniform adhesion, and industrial accidents are reduced due to prevention of safety accident caused by square iron.

FIG. 3 is a perspective view showing an embodiment of a screen printing plate stretcher of a printed circuit board according to the present invention; FIG.

Claims (5)

A screen printing apparatus for screen printing of a printed circuit board composed of two long axes and a short axis fixing base so that the screen having a pair of upper and lower support portions can be bonded to at least two or more frames, In the stretcher, a separator for placing the screen uniformly close to the entire upper surface of one side of the opposite side of the adjacent two side frames positioned in parallel between the adjacent frame and the frame to be fabricated is installed between the two long- Wherein the first and second substrates are bonded to each other. 2. The screen printing plate manufacturing method according to claim 1, wherein the separator installed between the long axis fixing bars has a rectangular cross section inserted into the fixing table, and a cross section of a portion pressing the screen is circular Stretcher for. [2] The apparatus according to claim 1, wherein one end of the separator is fixed by a fixing means so that a fixed position is adjusted along a rectangular groove by being inserted into a rectangular defect formed on an upper supporting part constituting one long axis fixing base as a fixed end, Wherein the support member is provided with a free end through which a rectangular through hole formed in an upper supporting portion constituting another long axis retention base is allowed to move along a rectangular through hole. [5] The apparatus as claimed in claim 3, wherein the fixing means comprises a press plate positioned on the upper side of the fixed end, and a screw rod screwed to the upper side support and one end exposed on the upper surface of the upper support and the other end fixed on the presser plate Wherein the stretchers for the screen-making of the printed circuit board are made of the same material. [5] The apparatus of claim 3, wherein the fixing means comprises: a rectangular hole formed in the upper surface of the upper support unit so as to penetrate through the rectangular hole; one end fixed to the fixed end and the other end exposed to the upper surface, Wherein the stripper is made of a bare wire. ※ Note: It is disclosed by the contents of the first application.
