Detailed Description

The utility model will be further described with reference to the drawings and embodiments.

First embodiment

Referring to fig. 1 and fig. 2 in combination, fig. 1 is a schematic structural diagram of a first embodiment of a solder mask white screen according to the present utility model; fig. 2 is a schematic structural view of the second white wire shown in fig. 1. A solder mask white screen comprising: a fixed frame 1;

the first limiting block 2 is arranged on the front surface and the back surface of the two sides of the top of the fixed frame 1, and a first white screen 4 is fixedly arranged at the bottom of the inner side of the first limiting block 2;

the second limiting blocks 3 are arranged on the front and the back of the two sides of the top of the fixed frame 1 and are positioned on the outer side of the first limiting block 2, and a second white screen 5 is fixedly arranged at the bottom of the inner side of the second limiting block 3 and at the bottom of the first white screen 4;

the object 6, the object 6 set up in the bottom of first white screen 4 just is located the top of second white screen 5, the outside of first white screen 4 with the outside of second white screen 5 all is provided with fixed network 7.

The object 6 is a circuit board.

The use of the fixation net 7 avoids the direct ink and the structure of the first white screen 4 and the second white screen 5 and increases the difficulty of cleaning them in the later stage.

The outside of the fixed net 7 is provided with a scraper 8.

The working principle of the solder mask white screen printing provided by the utility model is as follows:

when it is necessary to produce its circuit board, its second stopper 3 is placed in the proper position inside the fixing frame 1 according to the actual need, so that its second white wire 5 is in the proper position, then its circuit board is placed on top of the second white wire 5, then its first stopper 2 is placed inside the second stopper 3 and on top of the fixing frame 1, so that its first white wire 4 is fixed in the proper position, then the two fixing nets 7 are fixed outside the first white wire 4 and the second white wire 5, respectively, and inside the fixing frame.

By covering the outer surface of the fixed screen 7 with ink and scraping the ink from one direction to the other side in order by the scraping plate 8, the ink cannot adhere to the surface of the object through the positions of the first white screen 4 and the second white screen 5 due to the blocking of the first white screen 4 and the second white screen 5, and thus the printing work is completed.
