Problems solved by technology

However, the addition of conductive adhesive will make the overall structure of the membrane switch thicker, making it difficult to adapt to the control panel that requires high thinness; in addition, if the shielding layer is pressed repeatedly for a long time, it is easy to cause the shielding layer and the panel layer to be not tightly bonded, resulting in The case of electrostatic discharge is not good, so there is still room for improvement

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] An antistatic membrane switch, such as figure 1 As shown, it includes panel 1, upper circuit layer 2, isolation layer 3, lower circuit layer 4, and primer layer 5 arranged in sequence from top to bottom. mm printing glue. Wherein, the upper surface of the upper circuit layer 2 is printed with a grid-shaped conductive silver paste layer 6, and one end of the conductive silver paste layer 6 leads to an electrostatic lead-out line 7 and is grounded. Through the conductive silver paste layer 6, the membrane switch has an antistatic Features.

[0037] Such as figure 1 As shown, the conductive silver paste layer 6 includes silver paste grid lines intersecting vertically at a pitch of 6 mm and silver paste edge lines surrounding the outside of the grid lines, and the ends of the silver paste grid lines intersect with the silver paste edge lines. Through t...

Abstract

The invention discloses an anti-static thin-film switch and a manufacturing method thereof, and belongs to the technical field of electronic switches. According to the technical scheme, the main points are that the switch comprises a panel, an upper circuit layer, an isolation layer, a lower circuit layer and a primer layer which are sequentially arranged from top to bottom; all the layers are adhered into a whole through glue layers. The switch is characterized in that a latticed conductive silver paste layer is printed at one side, facing the panel layer, of the upper circuit layer, and a static lead-out wire is led out from one end of the conductive silver paste layer and grounded. The invention has the advantages that the anti-static function is added on the basis that the thickness ofan original thin-film switch is not changed basically, and the static release stability is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronic switches, and more specifically relates to an antistatic membrane switch and a manufacturing method thereof. Background technique [0002] Membrane switch, also known as light-touch keyboard, adopts an integral sealing structure composed of flat multi-layers. The new type of electronic components is a fundamental change in the appearance and structure of electronic products. It can replace the keys of conventional discrete components and perform the tasks of the operating system more reliably. [0003] Membrane switches generally include a panel layer, an upper circuit layer, an isolation layer, a lower circuit layer, and a primer layer arranged in sequence from top to bottom. The panel layer is made of colorless transparent sheets such as PET and PC less than 0.25MM, and the screen printing is exquisite. Patterns and texts are made. However, due to the insulating properties of PET and PC mat...
