The object of the present invention is to provide a metal mask frame for soldering to a printed circuit board (PCB), a flexible printed circuit board (FPCB), and a flexible printed circuit board (FCOF), in which a metal frame is embedded in a groove on a bottom surface, And a height adjustment member having a rectangular shape in which magnets are embedded at positions corresponding to the conductors of the reference frame, and a height adjustment member having a rectangular cross-sectional shape. do.

And the height adjustment members are formed in a pair such that the height adjustment members are provided so as to correspond to each other in the left-right direction or the back-and-forth direction of the reference frame.

And the "a" -type metal piece is embedded in the inner edge of the reference frame.

The height adjustment members are formed in the same manner as the right and left support frames facing each other and the front and rear support frames are equally formed, and magnets are embedded at positions corresponding to the conductors of the reference frame, And the metal mask frame is rotatably formed by the metal mask frame.

In the present invention, since the height adjustment member having a rectangular shape embedded with magnets is provided on each surface portion having adjacent corners in common, the height of the metal mask frame can be reduced, and a large number of frames can be stacked It is easy to move and store the frame, and the height of the frame can be adjusted. When the frame for metal mask is installed in the fixing device of the laser processing machine, the height of the frame can be adjusted by the set fixing device, It is a useful design with convenience such as.

FIG. 7 is a bottom view showing another structure of a reference frame which is a technical concept of the present invention; FIG.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a perspective view showing a structure of a metal mask frame to which the technique of the present invention is applied, FIG. 4 is a cross-sectional view showing a structure of a metal mask frame to which the technique of the present invention is applied, A plurality of recesses 21 on the bottom face are formed at regular intervals and are generally composed of a reference frame 20 in the form of a rectangular frame and a height adjusting member 30 which is brought into close contact with the reference frame 20 by magnetic force . Reference numeral 100 in the drawings denotes a film.

The structure of the reference frame 20 is made of a metallic aluminum material and the square bar 22 is formed in the shape of a square frame and a groove 21 is formed on the bottom surface of the square bar 22 as shown in FIG. And a plurality of magnets or metallic conductors 40 are installed in the recesses 21.

7, the structure of the reference frame 20 shown in FIG. 7 is made of a metallic aluminum material and the rectangular bar 22 is manufactured in the form of a rectangular frame The inside can be used with a hollow magnet or metallic conductor 40 provided at the vertex of the space 21a, preferably between the plane and the surface.

The height adjustment member 30 attached to the bottom surface of the reference frame 20 is formed on each of the surface portions 31 and 32 having the common edges at positions corresponding to the conductors 40 of the reference frame 20 A magnet or a metal conductor 40a is embedded in the groove 33 and has a rectangular cross section.

The surface of the height adjusting member 30 and the magnet or metallic conductor 40a provided in the groove 33 should be level. This is because the height of the metal mask frame 1 becomes irregular when a magnet or a metal conductor 40 protruding from the groove 33 is protruded.

The height adjusting members 30 are formed of two sets of the height adjusting members 30 so as to correspond to each other in the left and right or front and back directions of the reference frame 20. This is because it is easy to disassemble and assemble, and it is easy to handle and store.

As shown in FIG. 7, the "A" bracket may be installed in the space 21a at the inner corner of the reference frame 20. As shown in FIGS. 5 and 6, the height adjustment members 30 are provided with the support posts in the left and right direction facing each other in the same direction, and each surface portion having adjacent corners in common, A magnet is embedded in a position corresponding to a conductor and the hinge is rotatably formed by a connecting bar so that the height can be adjusted.

As shown in FIG. 4, after the film 100 is mounted on the upper portion of the reference frame 20, the metal mask frame is mounted on one side of the height adjusting member 30 The reference frame 20 and the height adjusting member 30 are attached to the conductor 40 provided on the reference frame 20 by using the magnet 40a.

For example, when the height regulating member 30 is formed in a rectangular shape and the height of the one side is 2 cm and the height of the other side is 3 cm, the height regulating member 30 is rotated to one side so that one side is attached to the reference frame 20, The total height of the reference frame 20 is 1 cm and the height of one side of the height adjusting member 30 is 2 cm so that the reference frame 20 and the height adjusting member 30 can be adjusted to 3 cm, The total height is 1 cm and the height of one side of the height adjusting member 30 is 3 cm. Therefore, when the reference frame 20 and the height adjusting member 30 are attached to each other, they can be adjusted to 4 cm.

Meanwhile, in order to fix a mounting hole for mounting a chip such as a resistor, a transistor, and a capacitor to a film, the height adjusting member 30 ) To adjust the overall height of the metal mask frame.

When the hole of the film is completed, when the frame for metal mask is moved or separated, when the reference frame 20 and the height adjusting member 30 are separated, the height of the reference frame 20 is 1 cm. So that it can be easily moved and stored in a state in which the weight and the overall height are reduced.

As shown in FIG. 3A, since two sets of the height adjusting members 30 are used, there is a risk of loss of the height. Therefore, as shown in FIG. 5, The adjusting member 30 may be used as a jig, but the connecting bar 36 may be fixed and the height adjusting member 30 may be hinged.
