Membrane Switch Production in The Factory

Membrane Switch Production in The Factory

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.

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.
