How does metal dome array work (2) The metal dome array can work effectively because the metal dome is arranged in an effective array. We generally divide these arrays into X rows and Y columns. These arrangements are not specific and are not limited to 4X4 and 5X5. It can also be irregular; we can

How does metal dome array work (1) A metal dome array is an independent circuit system. It is an array switch composed of multiple metal domes. Generally speaking, the structure of the metal dome array mainly has four layers. The most surface layer is the front foil. It is covered with spacer, which

For the button test and the bare test of the metal snap dome under the button, the general metal domes test requires the manufacturer to guarantee more than one million times, the strike speed is 2-3 beats per second, the strike force is 400G, and the test head is Flat head, the diameter is 1.5MM.If

Button film, also known as metal dome array. It is a PET sheet containing metal shrapnel, which is used as a switch on a circuit board such as PCB or FPC. It plays an important role as a tactile switch between the user and the instrument.The metal dome array on the membrane button is located on the

Metal dome array, is a piece of PET sheet containing a snap dome, used as a switch on PCB or FPC and other circuit boards, and it plays an important role of touch switch between the user and the instrument. Compared with traditional silicone keys, the conductive film has a better hand feel, longer l
