答：Different membrane buttons and traditional silicone keys work, it is covered with conductive metal film covered with metal points, when the button down movement, the button below the conductive adhesive material or metal shrapnel just fall on the metal point When the mask layer is not pressed, the isolation layer isolates the upper and lower lines. When the mask layer is pressed, the upper line is pressed together and coincides with the lower line to make the line conductive. Connect externally to the instrument (set by the customer) to achieve its corresponding function.

答：The surface structure of the film panel has many characteristics:
(1) Rough structures can hide fingerprints or even scratches.
(2) It can increase the visual ability and improve the positioning ability of the finger buttons.
(3) The non-reflective surface can improve the readability of the panel and the display by reducing the reflected light.
(4) The coating can optimize the performance of the display window.

答：Important design considerations for the surface structure of thin film panels are as follows:
(1) Applying the coating will increase some unit costs.
(2) Polyester and polycarbonate can be selectively applied to other types of sand surface, smooth surface, surface reflection treatment, and surface gloss treatment amount.

答：

1. The shrapnel of the membrane switch button kit needs to be placed properly. There can be no offset, otherwise it will affect the operation failure of the keypad.


2, the problem of color: the proportion of ink modulation is the main cause of color deviation, there is a strict color requirements, color range is small.
In terms of the cost of controlling the company, to achieve a very small range of colors, the cost to be paid is extremely high, the cost of the product is increased, and the unit price of the product is also correspondingly increased. It is also difficult for the customer to accept it. The range of color needs to be within a reasonable range.


3, the button bulge position, you need to open the mold to a suitable location, otherwise it will affect the appearance of the button. Adhesive is not sticky, in addition to the selection of raw materials, but also to confirm the shape of a good prototype, if the prototype has a groove you need to select a good quality adhesive, adhesive back to the right choice.

答：

Tactile switches are small in size and are standard parts. Sizes and related parameters must be combined with industry standards and the colors are relatively simple. Membrane switches can be ordered in different sizes, appearances and colors according to the requirements of customers. It is more convenient and flexible to use. The membrane switch has good flexibility, closed structure and waterproof structure, and has better adaptability to the environment.

The tact switch cannot function independently and must be used in conjunction with a PCB circuit board to form a complete open control system. Membrane switches integrate panels, switches, and conductive circuits to form a complete control system. Can provide customers with a whole switch solution.

答：1. The transparent film covering the front and back of the membrane switch is the display window of the protective membrane switch. Do not tear it off;
2. The feel, the large number of film surface stickers, and membrane switches all need to be vertically placed to prevent the key from prolonged heavy pressure failure;
3. The outlet of the membrane switch must be well protected and cannot be placed with the outlet facing downwards;
4. Membrane switches with a display window must prevent bending of the material when it is held and placed, leaving creases;
5. Membrane switches are stored indoors at room temperature. They should be protected against dust and moisture. There is no acid, alkaline or other corrosive gas in the surrounding air.

答：The use of back-adhesives is closely related to what kind of material the film panel is affixed to, and the commonly used ones include ordinary double-sided adhesives, 3M adhesives, and waterproof adhesives. Membrane switches, panel materials, in addition to requiring flatness and printability, the more important is to have flexibility and high elasticity characteristics.

答：

In general, the keys of the membrane switch only use color to express the position, shape, and size of the key body. In this way, the accuracy of the operation can only be recognized by the operator's visual sense, because there is no proper feedback information indicating whether the finger is pressed in the effective range of the switch to make the switch act, thereby affecting the confidence of the whole machine monitoring and the speed of the operation.

However, the key switch of the membrane switch is more visually enhanced, not only can accurately give the scope of the key body, improve the recognition speed, make the operator's touch more sensitive, but also enhance the appearance of the product's decorative effect. Therefore, the button bulging is increasingly welcomed by users and manufacturers.

答：Hard membrane switch means that the pattern and circuit of the switch are made on a common printed circuit copper clad board. The hard membrane switch is characterized by its simplicity, process stability, low resistance, and the ability to directly solder certain components of the circuit on its backside. In the case of a small area, the hard liner layer can be omitted. Hard membrane switches generally use metal guides as conductive labyrinth contacts, and therefore have a better handle. The unfavorable aspect is that it is not convenient to install the flexible membrane switch in the whole machine. It is often necessary to weld the plug and lead the lead through the flat cable. Information Feedback of Hard Membrane Switch In addition to beep signals and LED indications, metal touch springs are commonly used.

Hard membrane switch means that the pattern and circuit of the switch are made on a common printed circuit copper clad board.

Hard membrane switch Advantages: Easy access to materials, stable process, low resistance, and direct soldering of certain components in the circuit on the back side. In the case of a small area, the hard liner layer can be omitted. Hard membrane switches generally use metal guides as conductive labyrinth contacts, and therefore have a better handle.

Disadvantages of the rigid membrane switch: It is convenient to install the flexible membrane switch in the whole machine. It is often necessary to solder the plug and lead the wire through the flat cable. Information Feedback of Hard Membrane Switch In addition to beep signals and LED indications, metal touch springs are commonly used.

答：Membrane switches have a variety of circuits: such as flexible circuits, rigid circuits. Flexible circuits are mainly used in the connection of electronic products. The functional areas of the flexible circuit board can be divided into four types: lead lines, printed circuits, connectors, and multi-function integrated systems. Its representative flexible substrate is PET. The challenge for the flexible circuit industry is to use its technical advantages to keep pace with the development of computers, telecommunications, consumer demand and the market.
