Membrane switch is screen printing as the main process

Membrane switch is one of the few independent products that can be used for screen printing in the high-tech field.

Membrane switches have a decorative function and a marking function that are provided by a conventional panel. Besides a switch element and a switch function of the switch element, the thin film switch also has a switch connection and a lead line (that is, a switch circuit) function that connects the switch element and the host circuit. With the readings showing the transparent window and the indicator light transparent window function, the membrane switch is neither a single new type of panel nor a single switch element, but an electronic whole product set with functions and decorations is a novel electronic device.

Since the membrane switch has the characteristics of simple structure, beautiful appearance, excellent environmental resistance, long service life, lightness, thinness, shortness, and smallness, it conforms to the direction of high integration and high-intelligent development of modern electronic devices. The favor of technology products.

Strict quality inspection system

In addition to the color rendering of the ink switch and the color reproducibility required by the customer, the quality of the membrane switch must focus on the intrinsic qualities of the membrane switch, such as the key force, life, peel strength, and high and low temperatures. Constant wet heat and loop resistance, insulation resistance, pressure resistance and other indicators.

Thinking about high-tech screen printing

In addition to the above content, screen printing incorporates high-tech membrane switch manufacturing technology. There are also many new contents that are different from traditional screen printing, such as computer-aided design (CAD) and manual wiring design of membrane switch circuits; isolation Layer window and air duct design; Insulation ink and its ultraviolet (UV) curing application; Non-metallic conductor carbon paste application; High-tech computer numerical control (CNC) electronic autofocus precision punch on the membrane switch working environment And storage environment. Obviously we should be based on the working environment and storage environment of the membrane switch. Obviously, we should consider the membrane switch's structural design and material selection according to the working environment and storage environment of the membrane switch.

Today's screen printing has developed into a new multi-disciplinary modern screen printing technology integrating optical, mechanical, electrical, chemical, photochemical, microelectronics, and computer technologies.

Membrane switch technology in the production of the panel layer both the reproducibility of the color in the traditional screen printing, the color rendering of ink, which is the traditional screen printing decoration function, in the production of its circuit layer must also pay attention to the circuit The high-tech content is obvious because of its conductive properties, prevention of oxidation of silver paste circuits, migration of silver ions, multilayer interchange circuits, and the reliability of membrane switch products.
