Aviation and Marine Control is a high requirement field. Safety is the most important. Then the control panel’s durability and high quality are vital here. It must be waterproof and can withstand harsh climate changes. For example, the high temperature and very low temperature, salty moist atmosphere, directly strong sunshine with constant UV exposure, directly rain, chemical, oil dirty, vacuum environment, etc. In the case of these aviation control and marine control applications, LUPHI TECH makes the following suggestions for the membrane keypad or rubber keypad control panels:
Aviation & Marine Control: For Membrane Keypads:
· The overlay material must be high quality corrosion resisting, anti-UV PET.
· The keypad structure must be waterproof–meet IP67 and NEMA-4 standards.
· It is better to use FPC or PCB circuit to replace the common silver printed PET circuit.
· When assemble our membrane keypads on to your devices, try best to use melt adhesive or others to seal all slots
· Before navigation, check the function of the control panel to confirm whether it is correctly working or not.
· Make daily safety production checking. Once found any abrasions or other potential risk, use new keypad to replace the old one.
For rubber keypads:
· Use high quality silicone rubber material.
· Make post-cure processing.
· Design the wrap sides to seal the circuit in it.
· Use PCB/FPC circuit to replace the silver printed PET circuit.
· Make clear PU coating on keypad surface.
· When assemble our membrane keypads on to your devices, try best to use melt adhesive or others to seal all slots.
· Before navigation, check the function of the control panel to confirm whether it is correctly working or not.
· Make daily safety production checking. Once found any abrasions or other potential risk, use new keypad to replace the old one.
Rubber keypads itself has good touch feeling and good reliability. Usually the rubber keypad is not easy damaged, the users need pay more attention on the circuit layer underneath. If occurred any potential risks use the new circuit to replace the old one or change the whole keypad assemblies.
For this special application, especially for the marine control application, it is better for you to give the whole control panel assemblies to LUPHI TECH for manufacturing, which is convenient for LUPHI to design the best waterproof method and do the final assembly parts waterproof testing.
Membrane switches operate all sorts of products,from household appliances to industrial and medical equipment.Manufacturer produces quality membrane switches and touchscreen panels in a variety of sizes,designs, and functions. Please visit our factory and see how things operate here!
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.
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.
