Capacitive Touch Solutions
Capacitive Touch Screens
Custom capacitive touch screens engineered around the display, user interface, environment, and required touch performance.
Best for:
Sealed or flush-front HMIs in medical, industrial, automotive, and commercial equipment where users need reliable, intuitive touch interaction and a cleanable front surface.
Design focus:
Active area and sensor geometry, required touch points and gestures, controller tuning, cover-lens thickness, grounding/EMI, environmental exposure, and intended user interaction.
PEDOT Touch Technology
PEDOT-based transparent conductive sensor solutions for custom capacitive touch interface designs.
Best for:
Applications evaluating a transparent conductive polymer sensor where the optical, mechanical, geometric, or stack-up requirements call for an alternative electrode construction.
Design focus:
Conductive pattern geometry, optical transmission, stack-up, tail and interconnect design, controller compatibility, environmental requirements, and production considerations.
Capacitive Touch + PCBA Integration
Combine the touch interface with controller electronics, PCBA, display, and related components as a value-added HMI assembly.
Best for:
OEMs that want fewer supplier hand-offs and a more complete HMI subassembly with the touch interface, electronics, interconnects, display, assembly, and testing coordinated together.
Design focus:
Controller selection, PCBA interfaces, FPC and connector routing, power and EMI considerations, display integration, firmware requirements, assembly flow, and functional test strategy.
Custom Cover Lens
Custom cover lenses designed around the mechanical, optical, cosmetic, and environmental requirements of the touch interface.
Best for:
Interfaces that need the front surface to provide both product identity and protection through custom graphics, openings, finishes, optical windows, or mechanical features.
Design focus:
Material and thickness, printing and color requirements, coatings, optical clarity, bonding method, openings and edge features, environmental exposure, and dimensional tolerances.
Why Choose a Custom Capacitive Touch Solution?
Fit the Product
Design the active area, geometry, and interface around your enclosure and user experience instead of adapting to an off-the-shelf panel.
Tune the Interaction
Match sensor construction and controller behavior to the way the interface will actually be touched and operated.
Design for the Environment
Build the cover lens, sensor, bonding, and mechanical stack-up around the durability and operating conditions the product must handle.
Reduce Integration Risk
Consider the sensor, controller, display, interconnects, and PCBA together before interface conflicts show up later in the build.
Control the User-Facing Details
Choose the optics, graphics, surface treatment, openings, and finish that define what the customer sees and touches.
Build Toward Production
Resolve stack-up, interface, and manufacturability decisions early so the design has a clearer path from prototype into production.
Capacitive Touch + PCBA Integration
Move beyond a stand-alone touch screen with support for sensor, cover lens, controller electronics, PCBA, display, and value-added HMI assembly.

Why OEMs Choose Printec
Designed Around Your Application
We start with how the interface needs to function inside the finished product, then work backward into the right construction.
Engineering Collaboration
Our team can review sensor geometry, stack-up, interfaces, materials, and manufacturability while the design is still taking shape.
Fewer Supplier Hand-Offs
When the program calls for it, more of the interface can be coordinated through one manufacturing partner instead of across separate vendors.
Validation Before Scale
Prototype evaluation, functional testing, and design review help uncover interface or assembly issues before production volume increases.
Prototype to Production
Support can continue from early samples and design refinement into the manufacturing process used for the production program.
Responsive Program Support
Sales, engineering, and manufacturing support stay connected as requirements change and the program moves through its development stages.
Frequently Asked Questions
What capacitive touch screen solutions does Printec support?
Printec supports custom capacitive touch screens, PEDOT-based touch sensor options, custom cover lenses, controller electronics, PCBA integration, and value-added HMI assembly.
What is PEDOT touch technology?
PEDOT is a transparent conductive polymer that can be used as part of a capacitive touch sensor construction. Printec can evaluate PEDOT-based sensor approaches alongside the optical, mechanical, controller, and application requirements of the interface.
When should an OEM consider PEDOT for a touch application?
PEDOT may be considered when an application calls for an alternative transparent conductive sensor approach. The right construction depends on sensor geometry, optical requirements, controller compatibility, environment, and the overall product stack-up.
Can Printec integrate capacitive touch with a PCBA?
Yes. Printec can support integration of the touch sensor with controller electronics, PCBA, display, FPC and connector interfaces, testing, and additional HMI assembly requirements.
Do you support custom cover lenses?
Yes. Cover lens material, thickness, graphics, printing, coatings, openings, optical requirements, bonding, and mechanical features can be reviewed as part of the custom design.
Can Printec support a more complete touch HMI assembly?
Yes. Depending on the project, Printec can support touch screens, PEDOT sensor options, cover lenses, displays, controller electronics, PCBA integration, and value-added assembly as a more complete interface solution.
Have a Capacitive Touch Project?
Send us your drawings, interface stack-up, display or PCBA details, annual volume, and environmental requirements. We can help determine the right touch construction and level of integration for the program.
