Metal Domes Manufacturer
Metal dome array and sheet (dome array) is a PET sheet containing a metal dome, which is used as a switch on circuit boards such as PCB or FPC and plays an important role between the user and the instrument. The function of the tactile switch. Can be easily peeled off the release paper and stuck on the circuit board as a switch for electronic equipment. Therefore, from the perspective of metal shrapnel encapsulation, it also requires a ” Peel & Place metal dome”. You can place one or more metal domes in each array depending on the design purpose, mostly in the same number and position as the PAD of the circuit board to which it will be posted.
Dome Arrays (Metal Dome Arrays) are the most cost-effective simple switching solution with a superior tactile interface between your device and the user. It has a nice click feel compared to the membrane polyester switches previously used. Due to the use of metal domes, it also lasts longer compared to polymer dome sheets.
The metal dome contacts on the array (sheet) sit above the contact points on the PCB. When the metal dome is pressed, the center of the dome contacts the PCB and allows current to flow. This is how metal dome arrays work. Please click on our blog to learn How to Place a Metal Dome Array on a Circuit Board.
Metal dome arrays (metal dome) of various sizes can be manufactured and meet customer requirements. At present, the metal dome arrays we produce have the following basic types.
Used for: remote controls, MP3, MP4, GPS systems, electronic dictionaries, digital photo frames, etc.; mobile phones, PHS, cordless phones, handsets, walkie-talkies, etc. Digital electronic products with buttons…
Dome Array Features:
- Chemical resistance, weather resistance, and damage resistance;
- Ø 3 to Ø 6 mm, 100 g to 250 g driving force;
- Typical life span is greater than 1M cycles;
- You can choose the version with or without pits.
Dome array advantages:
- Shorten production time and easy assembly
The dome array is easy to assemble, and all domes can be placed on the PCB at the same time to shorten production time. The combination of automated processes will bring extremely low unit costs and improve production efficiency.
- Ensure quality
Dome arrays can reduce quality issues associated with dome placement because these arrays or dome sheets prevent misalignment or misalignment of dome pads, upper domes, and double dome misalignment during assembly.
Single Layer Dome Array
Single-layer dome arrays are used in dome arrays. Metal dome contacts are attached underneath Maylar, a layer of adhesive PET film. On the lamella, each dome contact has an air hole for a nice click feel.
Double Dome Array
EMI Printed Dome Array
– EMI Single Layer
EMI is printed on top of a single layer metal dome array (dome array).
– EMI Double Layer
Rubber Dome Array
LGF Dome Array
Custom Dome Arrays
Shanyo engineers independently developed the automatic shrapnel attachment and assembly machine equipment, which is more convenient, less troublesome, more accurate, and faster than manual labor. The metal shrapnel is independently developed and stamped and has multiple patents. Order now.
