We categorize membrane switches as the user-equipment interface utilities. In other words, these are simply utilities that let’s humans interact with a machine. The user is able to communicate commands to an electric device effectively. Do not confuse them with mechanical switches, as they are composed of copper and plastic parts, in comparison to a substrate and a circuit.
Most membrane switches have a simple, yet effective design. The core functionality of the switch lies in the meeting of electrical contacts on different membranes of the switch. To pass a command, the switch is pressed and the system’s two poles make contact, thus closing the circuit. Once you release the switch, it becomes open, and the connection between poles is terminated.
We firmly believe in designing and delivering the highest quality membrane switches. After all, these switches would elevate the user experience, feel and look of your product.
Membrane keypad is the demand of modern electronics as they are excellent keypads for the budget-conscious consumer. In the most basic sense, it features keys that are embedded into a single platform. These keys do not have separate moving parts. As membrane keypads feature pressure pads on which we print the key outlines and the symbols.
The mechanics behind the membrane keypad is very straightforward. There is a conductive metal present at the bottom of the keys. So, when a key is pressed, it results in a circuit creation with the underlying components.
Since there is no denying the importance of a membrane keypad. Therefore, we go the extra mile to ensure the quality and excellence of our membrane keypads. In addition to using premium quality material, we also have the highest-quality testing standard intact to ensure the efficiency, reliability, longevity, and robustness of our membrane keypads.
The development of electronic complete machine technology has resulted in the evolution of membrane panel design. One major change is the printing of the panels. In addition to screen printing, we now offer digital printing of the circuit board.
Our membrane panel consists of different layers of polyester printed and assembled together. It lets you create a custom human-machine interface at an extremely reasonable price. The benefits our membrane panel offers:
We sometimes refer to a graphic overlay as a nameplate. It is a printed graphic surface that we place on the top of a product’s internal electronics. The graphic overlay serves different purposes. First, it is extremely important for protecting sensitive components and material from wear and tear as well as environmental conditions. Second, it effectively provides a clean instinctive experience for users to interact with any device.
At Nicene, we firmly believe that graphic overlay needs to be of premium quality. It can’t be an afterthought of your design, after all, it is the most frequently used component that your user would come in contact with. Therefore, we always use top-of-the-line material. Our custom overlay feels, looks, and operates to perfection. It is bound to elevate your product’s entire experience.

6、Check whether the pasting glue is well and correctly pasted
7、If there is oil on the panel, be careful not to have oil, dust and other sundries on the surface;
8、If there is a panel that is manually stamped, hot pressed, and convex, check whether the convex position is offset, etc.;
9、Packaging inspectors should pay attention to the inspection while not scratching the panel with their fingers.
Line function part:
According to the actual drawings, it mainly detects resistance, electrical function, circuit principle, and short circuit and open circuit problems.
Extended part
Overlay:
The Overlay of Membrane Switch needs to be tested four 4 times: A. Before printing, it is necessary to check whether the panel material is selected according to the production documents, and perform a 100-grid test to check the ink adhesion. B. After printing, you need to check again whether the color number of the color meets the requirements of the drawing, and whether there is trachoma and light transmission. C. It is necessary to check whether the ink is peeled and scratched when embossing. D. Check whether the Overlay is scratched after placement.
Tactile Feedback:
10、Tactile Feedback test: Tactile Feedback test needs to pay attention to the height of the button and select the appropriate metal load and stroke. The selection of molds, the selection of structures, and the venting holes all need to be evaluated before the project is made when drawings are made to avoid all kinds of problems. QC testing also needs to pay attention to the Tactile Feedback test, unless it is a Non-Tactile Membrane switch without any hand feeling.
11、Membrane Switch circuit function test: Whether the resistance is too large, whether the electrical function is realized, and short circuit and open circuit problems need to be tested.
Backlit solution:
12、Whether the light source is evenly illuminated on the part that needs to be lit
Resin Dome:
13、Resin buttons are free of any impurities.
Problems and solutions that will occur in Membrane Switch:
14、Does the color need to be gradual and too many colors: Digital Printing
15、Whether the Membrane Switch is used in a high-voltage electrostatic environment (silver migration): 1. PI, RFI, ESD, etc. as the fixed layer 2. Select Flex Copper Circuit and Printing Circuit Board as the circuit.
16、Use and storage environment: The main impact is that the use and storage environment of Membrane Switch made by Adhesive, 3M adhesive can reach -25-80 degrees Celsius, while DT and Nitto adhesive tapes are usually 10-80 degrees Celsius and cannot be used at low temperatures.
17、Membrane Switch appears Newton’s ring: use OCA technology or UV dots printed between the PC window and the Overlay.
18、Scratches appear in the Membrane Switch window: Use hardened polycarbonate material for the panel or window, or use EBGmaterial as Overlay.
19、The resistance of the Membrane Switch is too high: the line is too long, and the Metal Dome needs to be plated with NI or GOLD. The best solution is to use Flex Copper Circuit or Printing Circuit Board.
20、The tactile feedback of the Membrane Switch is poor: Metal Dome needs to choose the appropriate load, and the thickness of the Overlay material needs to be 0.125-0.2mm and it needs to be convex. The adhesive of 0.3mm or less should be selected for the surface adhesive layer.
21、Membrane Switch function short circuit: Whether the silver oil circuit is fuzzy or short-circuited. Metal Dome is off.
22、The lead wire of the Membrane Switch should be scratched by electronic components, causing the circuit to be short-circuited: the circuit can choose to mount Mylar to solve the problem. Choose Flex copper circuit.
23、Metal Dome offset of Membrane Switch: Metal Dome fixture is required for the factory mounting process.
