Do you know why capacitive membrane switches can be popular? What is the difference between capacitive film switches and conventional switches? What are the functions and applications of capacitive film switches?
l What is the function of capacitive film switch?
l What are the applications of capacitive film switches?
l What are the characteristics of capacitive film switches?
The combined structure of capacitive membrane switch is divided into three parts, one is flexible membrane switch, one is capacitive touch screen, and the other is PCB electronic board, which can be combined into a complete capacitive switch. The flexible film switch is generally made of PET or PC film, because both have good soft performance, stable structure of the switch, good feel, mainly high transparency, will not affect the user to view the information on the display screen. Capacitive touch screens work by sensing electrical currents in the body. Its structure is four layers of composite glass screen. The inner surface and interlayer are coated with one layer of ITO, and the interlayer is used as the working face. Four electrodes. The PCB electronic board plays a major role in the product, connecting the current, connecting the circuit, transmitting signals, and also controlling the resistance, voltage, and current of the product.
1. What makes capacitive switches better than other switches? First, capacitive switches have no mechanical components, so they last longer than mechanical switches. In addition, capacitive switches can withstand some of the harshest environments, including outdoor environments. If dirt, dust, or moisture intrusion is a problem, capacitive switches may be the best option. The key thing to remember about capacitive switches is that they require direct contact with a conductive object to operate. This is why using a stylus usually doesn't work (unless it's a capacitive stylus).
2. capacitive switches can also be used in a wide range of applications including vending machines, smartphones, tablets, human-machine interfaces (HMIs), industrial controls, appliances, infotainment centers and more. In addition, they support the integration of other features, such as light-emitting diode (LED) backlighting.
1. Since most capacitive membrane switches are of four-layer construction, the material cost will be lower than six-layer membrane switches. At the same time, the shrapnel-free design can also reduce the material cost and labor cost.
2. The collision-free capacitive film switch button can easily have a lifetime of up to a million times, compared to a million times for most metal domes.
3. capacitive film switches can be made in the form of backlighting at a lower cost
4. The capacitive film switch has no metal dome and uses a flat panel design. Installing a backlight is easier to light than installing a metal dome membrane switch, and the brightness is more uniform.
If you are looking for a good quality and reasonable price of capacitive membrane switches, LuphiTouch can provide you with the best.
LuphiTouch,a professional OEM manufacturer of user interface subassembly products.LuphiTouch is located in south of China in Dongguan,and since 2008 the core of its business is manufacturing an export of membrane switches & keypads, capacitive switches, silicone Rubbert keypads, graphic overlays, and touchscreen panels. Besides,they also offer mechanical design and PCBA development, as well as development of single-chip solutions, keypad backlighting, and turnkey assembly.
The production of high-tech interface products requires clean and well functioning operations.let's get to know that how LuPhi complies with industry requirements.
The factory has many strengths-we use high quality imported raw materials and have a skillful team of workers,as well as modern production and testing equipment,our facility is certified with ISO 9001,medical ISO13485,environmental ISO14001,health and safety ISO45001, and the production areas are equipped with 10000 and 1000 class cleanrooms.our products obtain main quality certificates for major markets, such as Europe,North America and Australia.
let's go to the workshops to see how the products are made！
Design: First，the product concept takes shape in the R&D department，where LuPhi's engineers design and create initial samples.
before mass production,their PP samples will undergo various function and environmental testing, such as button actuation life testing,high-low temperature constant temperature,and humidity testing,as well as salt-spray & waterproof testing,ink adhesion force testing,click ratio test, and many others.
01 KEY PROCESS OF PRODUCTION
Once the pre-production samples pass all necessary testing and materials arrive at the factory,production begins.LuPhi uses high-quality imported materials, such as 3M adhesive,Autotex polyester,nikomatic connectors, and many other components.
The first step of production starts from raw material cutting- where overlay films,circuit films and adhesive layers are cut by automatic cutting machines with high accuracy.
After that,the cut materials are transferred to a silk screen printing workshop,where first the ink is prepared to match the exact color requirements of the customer, and silkscreens are created for printing.
Then films and screens are moved to automatic and semi-automatic silk screen printing machines.
Following the printing,semi-finished products,are further passed to a baking treatment in a 12-meter drying tunnel until the ink is completely dried and cured, LuPhi also has 4 drying ovens to increase efficiency at this step.
For many membrane switches with embossed buttons，the printed graphic overlays also undergo embossing in semi-automatic embossing machines.
In the end, all layers of the final products, such as graphic layers, adhesive layers, circuit layers and others are assembled and laminated together, creating the about-to-be final membrane switch.
After assembly,products are passed to auto die cutting&high accuracy cutting machines to cut out the membrane switch panels and form the final product shape.
At each production step,products are fully inspected with 100% appearance and function check, to ensure that every product received by customers is qualified.
Our QC inspectors check the dimensions, printings, workmanship and electrical functions, which undergo testing twice after the circuit is printed and assembly is finished.
Packing: Once products pass the inspection, they'll be cleaned, packed into inner and expert packaging, and shipped to customers all over the world.
02 COMPANY DEVELOPMENT
With our team, about our history and recent achievements:Luphi was established in 2008 for production of human interface products. to support customers from various industries, including automotive, industrial,medical&healthcare industry, household appliances, and others.
over the past year, we achieve a 40% increase in sales through the concerted efforts of the whole team.At the same time, we have straightened the corporate culture, further improve employee satisfaction and happiness index,enhance team cohesion,and laid a solid foundation for the future performance growth.
How are we planning to support the strong demand at the market, in the next couple of years?To support the market demand in customer’s needs,in the next 5 to 10 years,we will increase investment into research and development, and will develop user interface modules for a variety of coffee machines, mixers, vending machines,juicers and other small household appliances.
At the same time,we will continue to strengthen the development and customization ability in high-end application fields,and achieve standardization in middle and low-end needs and customization of high-end needs.
03FACTORY AUDIT, SUMMARY
Now, end of tour to LuphiTouch, These have several advantages of the factory-our facility follows : ISO9001, medical ISO13485,environmental ISO14001, health & safety ISO 45001, and production areas are equipped with 10000 class and 1000 class cleanrooms, that guarantees a clean environment for manufacturing.
