Customizable Surface Mount Membrane Type Keyboard For Hairfoil Device

Creating a customizable surface mount membrane keyboard for a hairfoil device involves several key considerations. Here’s a breakdown of the process:

1. Design Specifications

• Form Factor: Determine the size and shape of the keyboard to fit the hairfoil device.
• Key Layout: Decide on the number of keys and their arrangement. Common layouts include QWERTY or custom layouts based on user needs.
• Key Functionality: Define what each key will do (e.g., power on/off, temperature control, fan speed).

2. Material Selection

• Membrane Layers: Typically, a membrane keyboard consists of three layers:
  • Top layer (graphic overlay)
  • Spacer layer
  • Bottom layer (circuit)
• Durability: Choose materials that can withstand repeated use and exposure to moisture or chemicals.

3. Custom Features

• Backlighting: Consider adding LED backlighting for visibility in low-light conditions.
• Custom Graphics: Design the top layer with user-friendly symbols or labels.
• Touch Sensitivity: Decide if you want to implement capacitive touch technology for a more modern feel.

4. Manufacturing Process

• Prototyping: Create a prototype to test the design and functionality.
• Testing: Conduct usability tests to ensure the keyboard meets user needs and is durable.

5. Integration

• Connection: Ensure the keyboard can connect seamlessly with the hairfoil device (e.g., via USB or Bluetooth).
• Firmware: Develop necessary firmware to interpret the keyboard inputs correctly.

6. Customization Options

• User Preferences: Allow users to customize key functions or layouts through software.
• Aesthetic Choices: Provide options for different colors and finishes for the keyboard overlay.

7. Documentation and Support

• User Manual: Create detailed documentation for installation and customization.
• Customer Support: Offer support for troubleshooting and customization assistance.

 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

Common Membrane switch structure
