Reliable and robust interfaces able to cope with the most difficult environments.
LuphiTouch can design and manufacture various kinds of membrane switches, rubber keypads, touchscreens for military and defence industry.
For the military and defence equipments or devices which have very high requirements for the quality, reliability and stability of the keypads. The challenges are quite unique. It has very rigorous regulations and specifications. Excellent performance is mandatory. These are also our objectives for our membrane switches, keypads, rubber keypads, touchscreens, overlays etc. must be achieved. Frankly speaking, we do so with flying colors.
Material selection for Defence Application Keypad:
When we design a membrane switch for military and defence application, first, we must consider to select proper raw materials. For the graphic overlay, we suggest to use Polyester material. As per your application, we can select Autotex, Autotex XE or Autoflex series polyester materials. For the standard im-room application, then the standard Autotex series polyester is ok enough. If there will be a big display window on membrane switch, then we suggest to use Autoflex series polyester which is a kind of anti-scratch polyester material. If the application is for outsides, then we suggest to use Autotex XE series polyester material which is a kind of UV-resistant polyester material.
For the spacers(adhesives) of the membrane switch, we suggest to use 3M brand adhesives for military and defence keypad applications. But 3M has many different types of double sides adhesives and single side adhesives. To use which model for overlay spacer, circuit spacer and rear adhesive based on the keypad thickness and other real applications.
As to the circuit layer, we suggest to use copper FPC circuit or rigid PCB circuit. Try to avoid using silver printed polyester circuit. Both the copper FPC and rigid PCB circuits have more higher reliability and stability than silver printed polyester circuit.
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.
Material Cutting:
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.
Silkscreen Printing:
Then films and screens are moved to automatic and semi-automatic silk screen printing machines.
Drying:
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.
Embossing:
For many membrane switches with embossed buttons，the printed graphic overlays also undergo embossing in semi-automatic embossing machines.
Assembly:
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.
Punching:
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.
FQC:
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.
