Elastomeric connectors create electrical contact by controlled compression between mating conductive pads. Instead of solder joints or mating connectors, conductivity is achieved through alternating conductive and insulating layers embedded in an elastomeric profile.
The result is a direct PCB-to-display or PCB-to-PCB interface with minimal Z-height and no permanent electrical bonds.
Key Advantages for Space-Constrained Designs
1. Ultra-Low Profile Interconnect
Elastomeric connectors eliminate the height associated with:
- FFC/FPC connectors
- Board-to-board headers
- Cabled assemblies and strain relief
This enables thinner enclosures, tighter internal packaging, and greater mechanical freedom.
Many displays feature a rigid FFC tail. You can browse a wide range of LCD, OLED, and graphic display modules on popular distributor sites.
2. Single-Piece, One-Step Assembly
From an assembly perspective, elastomeric connectors are intentionally simple:
- One connector component
- One compression plane
- No mating cycles or latching features
This reduces assembly time, minimizes operator error, and improves yield in both low-volume and production environments.
3. No Soldering Required
By eliminating solder joints, elastomeric connectors remove several common failure points:
- Cold solder joints
- Reflow-related damage
- Thermal stress on displays or PCBs
- Rework and repair risk
This makes them particularly well-suited for sensitive displays and mixed-material assemblies.
4. High Contact Density in Minimal Space
Despite their small footprint, elastomeric connectors support high signal counts with consistent electrical performance. When properly compressed and aligned, each conductive layer forms a reliable vertical (Z-axis) connection.
5. Improved Shock, Vibration, and Serviceability
Because electrical contact is maintained through compression rather than rigid metal interfaces, elastomeric connectors perform well in environments subject to:
- Shock and vibration
- Repeated servicing
- Mechanical tolerance stack-ups
Displays and PCBs can be removed and reinstalled without damaging the interconnect.
