Dome Arrays & Dome Sheets

Custom Dome Arrays & Dome Sheets

Dome sheets or dome arrays are a tactile interface between the user and keyboard. They are made of a pre-cut polyester adhesive and domes (typically polyester adhesive 0.05 mm thick with a 0.03 mm thick sheet of acrylic adhesive).

Dome arrays are applied to the printed circuit board after peeling off the liner and aligning the array in one single operation. The dome arrays not only simplify the assembly process but they ensure the most accurate placement of domes on the PCB.

CSI Keyboards Dome Array

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(s). 

Advantages of Using Dome Array:

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.
