Customizable Surface Mount Custom Membrane Keypad For Hairfoil Device

Customizable Surface Mount Custom Membrane Keypad For Hairfoil Device

Components of a Membrane Keypad

1. Top Layer:

   • Printed graphics or symbols.
   • Can be made of various materials for durability and aesthetics.

2. Spacer Layer:

   • A non-conductive layer that separates the top and bottom layers.
   • Contains holes for the keys to collapse upon pressing.

3. Bottom Layer:

   • Contains conductive traces that complete the circuit when a key is pressed.

Design Considerations

• Size and Shape: Tailor the dimensions and layout to fit your application.
• Key Functions: Decide on the number and type of keys (momentary, toggle, etc.).
• Material Selection: Choose materials based on environmental exposure (e.g., moisture, dust).
• Graphics and Text: Consider readability and usability for end-users.
• Backlighting: Optional feature for visibility in low-light conditions.

Applications

• Consumer electronics (like remote controls)
• Industrial equipment
• Medical devices
• Automotive controls

Customization Options

• Color and Finish: Various colors and textures can be used.
• Key Shapes: Different shapes for different functions or user preferences.
• Adhesive Backing: For easy installation on surfaces.

Manufacturing Process

• Prototyping: Create initial designs using CAD software.
• Testing: Evaluate the keypad for durability and functionality.
• Production: Mass production can be initiated once the design is finalized.

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
