Screen Printing Membrane Panels Silver Conductive Circuit With 2.54MM Pitch

Screen Printing Membrane Panels Silver Conductive Circuit With 2.54MM Pitch

Key Considerations

1. Material Selection:

   • Substrate: Choose a flexible substrate like PET or polycarbonate for durability and flexibility.
   • Conductive Ink: Use silver conductive ink for optimal conductivity.

2. Design Layout:

   • Ensure that the circuit design matches the 2.54mm pitch for compatibility with your components.
   • Design using CAD software to layout the circuits accurately.

3. Screen Printing Process:

   • Prepare the screens with the desired circuit pattern.
   • Ensure proper emulsion and exposure settings for fine details.

4. Curing:

   • Cure the printed circuits properly to achieve the desired conductivity and adhesion.

5. Testing:

   • Conduct tests for continuity and functionality after printing and curing.

Applications

• Keypads: Often used in devices requiring tactile feedback.
• Control Panels: Useful for various electronic devices.
• Sensor Applications: Can be applied in touch sensors and other interfaces.

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
