Product Description
Conductive Silver Ink Printing Membrane Switch Design For WIFI Telecommunication Device
Types of Membrane Switches
-
Non-Tactile Membrane Switches:
- Economical and reliable but do not provide direct feedback to the user.
- Custom shapes and sizes can be easily created.
-
Tactile Membrane Switches:
- Provide a noticeable snap action feedback through conductive stainless steel or polyester domes.
- Feedback can be visual, audible, or tactile, enhancing user interaction.
-
Mixed Panels:
- Combine both tactile and non-tactile switches for flexibility in design.
-
PCB Backed Membrane Switches:
- Incorporate a printed circuit board for structural support and additional components.
Key Components
- Graphic Overlay: The visual interface that users interact with, which can be customized in color and texture.
- Circuit Layers: Typically consist of a top circuit layer, dome retainer, dome spacer, bottom circuit, and rear adhesive.
- Display Windows: Can be integrated for visual feedback, with options for transparency and color tinting.
Material Selection
- Polycarbonate: Commonly used for its ease of printing and cost-effectiveness, but less durable than polyester.
- Polyester: Offers superior durability and chemical resistance, suitable for high-use applications.
Design Considerations
- Circuit Configuration: Can be designed as a common bus or matrix layout, affecting the switch's reliability and manufacturing ease.
- Venting: Necessary to allow air displacement when the switch is pressed, ensuring a sealed design.
- Shielding: Options for ESD, EMI, and RFI shielding can be incorporated depending on the application requirements.
Production Process
- The design process may involve creating custom artwork, selecting appropriate materials, and determining the best printing methods (screen printing, digital printing, or a combination) to achieve the desired functionality and aesthetics.
Specification:
1)Material (for front or face overlay)
Polyester:
1.Highly versatile for embossing
2.Highly resistant to chemicals
3.Better durability
4.For internal and external use, UV resistance
Polycarbonate:
1.Different surface(Glossy, Matt) and thickness(From 0.12mm~2mm)
2. cost-effective in price
3.For internal and external use
2) Embossing
Rim embossing/pillow embossing/dimple embossing
Graphic overlays can be embossed in order to insert domes/LED, leave space for mechanical keys/LED and provide tactile indications and better tactile feeling.
3)Windows(for display function)
1. print different colors windows, As transparent grey/Red/green window for display
2. Clear/Transparent window for LCD display
2. Matt/semi-transparent window for LED
4)Keys/buttons
Tactile keys---with metal dome or poly dome
Non-tactile--silver printing dots with flat key
5) Embeded LEDs
Small, brilliant lights only about 0.02’’ in height. Avaliable in several vibrant colors.
LED colors: white, yellow, orange, green, red, or double colors LED.
6)Cable
It is an extension of the printed circuit and is used to communicate with your device.
7)Types of connector
1.Zero insertion force (ZIF) connector; 2.Female connector; 3.male connector
8) EMI / RFI / ESD Shielding
use an aluminum foil shielding / a clear ITO electrical conductive polyester
9)Adhesive
mostly used are 3M-double-side glue
10)Backplate-
in aluminum, polycarbonate, acrylic, PCB
