Embodiment Construction

[0012] The printing screen provided by the technical solution and its manufacturing method will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] see figure 1 , the printing screen 100 provided by the embodiment of the technical solution. The printing screen 100 includes a screen frame 110 , a screen 120 and a metal sheet 130 .

[0014] The screen frame 110 can be a metal screen frame, a wooden screen frame or a plastic screen frame. The shape of the screen frame 110 can be designed according to actual needs during use. In this embodiment, the screen frame 110 is a rectangular metal screen frame, such as an aluminum alloy screen frame.

[0015] The surrounding edges of the screen 120 are connected to the inside of the screen frame 110 , so that the screen 120 is stretched on the screen frame 110 . The screen 120 has certain elasticity and tension, which can provide the specific deformation required by the printing screen 100...

Abstract

The invention relates to a printing screen which comprises a screen frame, a silk screen and a metal sheet with a screen printing pattern; the silk screen is arranged at the screen frame in a tightening way; the metal sheet is fixed on the surface of the silk screen; the screen printing pattern of the metal sheet is ablated by the laser; the precision of the screen printing pattern is +0.005 to +0.02mm or -0.02 to -0.005mm. The invention also relates to a manufacturing method of the printing screen. The printing screen with high precision is beneficial to a circuit board with high density to carry out precise screen printing, can effectively prevent the scrapping of the circuit board caused by the screen printing and improve the yield of manufacturing the circuit board.

Description

technical field [0001] The invention relates to a printing screen plate and a manufacturing method thereof. Background technique [0002] Screen printing is a multi-purpose printing technology, which has always played an important role in the field of circuit boards. It is the key to realize the precise coating of ink, glue and solder on circuit boards. In the process of circuit board production, when screen printing, the circuit board is placed directly under the printing screen with the screen printing pattern, so that the ink, viscose and solder pass through the screen printing of the screen under the extrusion of the scraper. The pattern is applied to a predetermined area on the circuit board. [0003] The production accuracy of the screen printing pattern of the printing screen is closely related to the printing accuracy of the printing screen. Printing screens are usually made of nylon, polyester, silk, metal mesh or sheet metal. When making metal sheet printing scr...
