Custom Design Fpc Touch Panel With Tactile Embossing Domes
Designing a custom FPC (Flexible Printed Circuit) touch panel with
tactile embossing domes involves several key considerations:
1. Material Selection
- FPC Material: Choose a flexible PCB material like polyimide for durability and
flexibility.
- Embossing Dome Material: Typically made from silicone or rubber for a tactile feel.
2. Design Specifications
- Touch Sensitivity: Determine the required sensitivity and response time for the
touch panel.
- Dome Size & Shape: Define the dimensions and profile of the embossing domes to
ensure comfort and usability.
- Layout: Create a schematic layout for the touch sensors and dome
placements.
3. Circuit Design
- Touch Sensor Technology: Decide between capacitive or resistive touch sensing based on
application.
- Connection Points: Ensure proper routing for connections to the main board.
4. Prototyping
- 3D Modeling: Use CAD software to create a 3D model of the touch panel and
domes.
- Prototype Fabrication: Fabricate a prototype to test the tactile feedback and touch
sensitivity.
5. Testing & Validation
- Conduct usability testing to ensure the panel meets user
expectations.
- Validate the performance in different environmental conditions.
6. Production Considerations
- Manufacturing Process: Choose a reliable manufacturer with experience in FPC and tactile
components.
- Quality Control: Implement a quality control process to ensure each unit meets
specifications.
Additional Features
- Backlighting: Consider integrating LED backlighting for visibility in low-light
conditions.
- Customization: Offer options for different finishes and colors to match the
device design.
Specification:
| Overlay material ---For front or face overlay |
| Polyester | Polycarbonate |
1 Highly versatile for embossing
2 Highly resistant for chemicals
3 Better durability
4 For internal and external use | 1 wide range of the surface finishes and thicknesses
2 More cost-effective
3 For internal and external use
4 many Lexan label choose |
| Embossing --- Graphic overlay or up circuit can be embossed in order to insert
metal stainless steel domes for good tactile when press .Leave
space for mechanical keys and provide tactile indications |
| Pedestal embossing | Rim embossing | Pillow embossing | Dim embossing |
| Windows or LCD --- For display functions |
| Printed colors windows such like red ,black and so on | Transparent finishes windows |
| Keys |
| Tactile Keys :witch metal domes or Poly domes ,Metal dome with
different diameter and pressure kinds | Non-tactile keys: printed silver spot on the circuit |
| LEDs ---Miniature LEDs ,LED colors :white ,Green ,Red ,Blue ,Yellow ,Orange
and others |
| EL and Sensors or inductors --- EL can be light any place where where you like ,and sensors can be
used as LEDs |
| Cables --- is extension of circuit and communication with your device |
| Screen printing conductive silver cable | Copper plated cable /Polyimide or FPC | PCB board |
| Types of connector --- 1 Zero insertion force(ZIF) with 0.3MM ,0.5MM ,1.0MM,1.25MM pitch
;2 Female connector with 2.54MM pitch; 3 Male connector |
| Shielding --- For protection function |
| Gasket seal/Waterproof :protect the conductors against from the
humidity and splashes | EMI/RFI/ESD Shielding: use an Aluminum foil shielding /clear ITO
electrical conductive polyester to protect |
| Rear Adhesive --- Mostly use the 3M double-side mounting glue brand of USA. Also
accepted others such like Lohmann and others |
| Back plate --- Use in Aluminum ,Polycarbonate ,Acrylic Or PMMA |
| Matching color --- PMS or RAL Is best ,CMYK or RGB also can be ok if you can
supply PMS Or RAL |
| Standard Tolerances :+/-0.2MM |
