Custom Dome Arrays & Dome Sheets

    Dome Array assemblies consist of metal domes on a pressure sensitive adhesive PET sheet or array. Each metal dome is in the center of a kiss-cut adhesive square or circle, with release liner backing which can be easily peeled off during the assembly process. We also have the ability to add improved tactility by adding actuators to the tops of the domes which can also increase the height to your key

Time: the main advantage of utilizing a dome array is ease of assembly: production time is greatly reduced by placing all of the domes on the PCB simultaneously. 

Quality: reduces quality issues stemming from dome placement, as these arrays or dome sheets prevent misplacement or misalignment of domes on the dome pads and double dome errors during assembly.

The primary advantage of dome array implementation lies in assembly simplification:

• Production throughput is optimized via simultaneous placement of all domes on PCB (±0.15mm positioning accuracy)

• 60%+ cycle time reduction compared to discrete dome installation

Quality Assurance:

Pre-engineered arrays eliminate three critical failure modes:

Dome misalignment (±0.15mm maximum offset guaranteed)

Double-dome installation (anti-error matrix design)

Solder drift (high-temp adhesive withstands 260℃ reflow)
