Conductive Silver Ink Printing Custom Membrane For WIFI Telecommunication Device

Conductive Silver Ink Printing Custom Membrane For WIFI Telecommunication Device

Steps to Create a Custom Membrane

1. Design Preparation

   • CAD Software: Use computer-aided design (CAD) software to create the layout of the membrane, including the conductive paths, component placements, and any necessary cutouts.
   • File Format: Export the design in a suitable format (e.g., SVG, DXF) for printing.

2. Material Selection

   • Substrate: Choose a flexible substrate that is compatible with the silver ink, such as PET (polyethylene terephthalate) or paper.
   • Conductive Ink: Use high-quality silver ink designed for printing electronic circuits. Ensure it has good conductivity and adhesion properties.

3. Printing Process

   • Screen Printing or Inkjet Printing: Depending on the complexity of the design, choose either screen printing for larger runs or inkjet printing for intricate designs.
   • Layering: Apply multiple layers if needed to achieve the desired thickness and conductivity.

4. Curing

   • Drying: Cure the printed ink according to the manufacturer’s specifications. This may involve using heat or UV light to ensure the ink adheres properly and maintains conductivity.

5. Assembly

   • Component Placement: Integrate any electronic components (e.g., resistors, capacitors) onto the printed membrane.
   • Connections: Ensure proper connections between the conductive paths and components.

6. Testing

   • Electrical Testing: Verify the conductivity and functionality of the printed membrane with multimeters or circuit testers.
   • Performance Testing: Check the overall performance of the membrane in the Wi-Fi device to ensure it meets the required specifications.

7. Finalization

   • Encapsulation: Optionally, encapsulate the membrane for protection against environmental factors.
   • Integration: Install the membrane in the telecommunication device.

Considerations

• Design Complexity: Ensure your design is optimized for the printing method chosen.
• Ink Properties: Research the specific conductive silver ink you plan to use, as different inks may have varying properties.
• Regulatory Compliance: Make sure your design complies with local regulations regarding telecommunications devices.

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
