Metal Dome Array

Dome Arrays (also named metal dome sheets, peel & place metal dome), are pre-loaded polyester dome carriers backed with pressure sensitive adhesive. Arrays come loaded with the metal domes of your choice, cut to the size and shape that you specify. Whether your circuit board is populated with one metal dome or one hundred metal domes, our metal dome arrays help reduce your labor costs by easing the assembly process.

Dome Arrays assemblies have become common practice with many membrane switch/circuit manufacturers who are utilizing them to help take costs out and speed up assembly times. As the operator places one large dome array in one application instead of each dome individually, production time is reduced dramatically. Quality improvements and benefits can also be enjoyed with the reduction in placement errors.

The dome sheet or dome array is the tactile interface between the user and the keyboard. Depending on the drawing type, apply the dome array to the printed circuit board after peeling off the liner and aligning the array. The dome array simplifies the entire assembly process and ensures accurate dome placement on the PCB. Dome array assemblies consist of a pressure-sensitive adhesive PET sheet or metal dome on an array. Each metal dome is centrally located for a snug fit and has a release liner backing that peels off easily during assembly.

Learn about the efficiency of our Shanyo standard metal dome switch array, which comes with a pitched PET tape. This PET glue is securely applied to the metal dome switch and adhered to a non-stick carrier material. As you complete the entire process, carefully peel the metal dome switch array from the carrier transparent release film and place it securely on the printed circuit board, FPC, PCB, or film.

Our metal dome switch arrays are available in a variety of styles and can be customized according to customer needs. These standard metal dome switch arrays are usually mounted on single or double-sided printed circuit boards, flexible circuits, and on the film.

We have a team of professionals ready to meet your specific requirements. Rest assured, all dome arrays are professionally manufactured to your precise specifications in our state-of-the-art factory in Qingdao, China. For other dome styles as standard please contact us directly.
