Product Details

What are Copper Flex Membrane Switches?

FPC Copper Flex membrane switches can be produced using polyester or polyimide as the base material, depending on your interface requirements. A very thin sheet of copper is laminated to the flexible film substrate then chemically etched away, leaving copper traces. The etching process is not environmentally friendly due to the chemicals used, and is also more expensive than screen printing the silver traces used in Silver Flex membrane switches. Copper Flex switches can be constructed as:

Single-sided – conductive traces one side of the film substrate
Double-sided – conductive traces both sides of the film substrate
Multi-Layer flex – a laminated “sandwich” of numerous layers with conductive traces
Rigid-Flex – a laminated combination of a Copper Flex switch with a rigid FR4 PCB membrane switch

What are the Advantages of Copper Flex Membrane Switches?

Copper Flex membrane switches are ideal for smaller designs where dense circuit patterns or trace routing limitations exist. This design also allows the ability to accommodate the complex circuit patterns of a FR4 rigid printed circuit board with the flexibility of a membrane switch. Copper Flex keypads also have the advantage of being able to hard solder active and passive components into the assembly, making it a good choice in high-vibration, high-reliability environments.

What are the Copper Flex Membrane Switch Design Options & Considerations?

Single-sided, double-sided, and multi-layer designs available
Lower electrical resistance and higher conductivity vs. traditional Silver Flex membrane switches
Tight trace routing capabilities
Same thin profile and flexibility as Silver Flex Membrane Switches
Plating options can be tin-lead, nickel, or gold
Tactile and non-tactile with either metal or polyester tactile domes
Pillow or rim-embossed graphic overlays
LEDs and other components can be soldered and are more robust
Graphic overlays that can be digitally printed, screen printed, or a combination of both
The graphic overlays can incorporate transparent and tinted display windows, as well as selective textures and UV hardcoat surface finishes

Comparison Chart

Characteristic	Silver Flex	Copper Flex
Printing vs. Etching	Conductive silver ink traces are screen printed onto the film substrate.	A sheet of copper is chemically etched away, leaving conductive traces. More expensive than screen printing.
Pliability/Weight	Silver traces are lightweight and more flexible than solid copper traces.	Solid copper traces are heavier and more durable than softer printed silver traces.
Conductivity	Resistivity approx 50 mOhms/sq 1mm x 80 mm trace = 4 Ohms 0.5mm x 80mm trace = 8 Ohms	Lower electrical resistance and higher conductivity.
Price	Low to Moderate	Expensive to very expensive
Soldering	No. Components are attached with conductive adhesive.	Ability to solder active and passive components into the switch design.
Pitch	Minimum of 1.0mm	Possible pitch 0.5mm and 0.3mm for ZIF connector

FAQ

1. How to make an order?
Please tell us your material,artwork design,logic circuit principle chart,size,surface,usage etc. And better send us the design drawing or samples together with other detailed datas, then we’ll customize the membrane switch upon your requests.
2. Sample available?
Yes, but based on freight collect. Most of the items are customized for clients, so molding charge is needed.
3. How to guarantee the after sales service?
We will track the production situation of the goods during the whole process,we promise the goods will be shipped to you smoothly. If any problem happened, we will provide the best solution for you.
4. Shipping ways & Delivery Time?
Shipping by: UPS/ Fedex /DHL /TNT or other ways specified.
Delivery time: 10~15 days after payment received.
5. Payment terms:100% T/T in advance.
