If you want to assemble a triangular metal dome, you are in the right place! Our high quality metal domes are ideal for constructing strong and durable domes of all shapes and sizes. Here are some tips and tricks for assembling a triangular metal dome:
The installation methods of metal dome can be roughly divided into three types. Different products have different assembly requirements for dome, so the design of dome is also very different.
Some customers will say that the triangular dome with legs should be soldered to the FPC/PCB board. But according to the principle of using the triangular metal dome, this is wrong. Because the triangular dome can perform the function of conducting the circuit on the PCB, when the metal dome is pressed down, the dome will extend to a certain extent around. When the two corners of the triangular dome are fixed, when the dome is pressed, the dome cannot extend to the surroundings, but because the force is increased, the life of the dome will be shortened, resulting in the dome not being able to perform its special performance normally. Therefore, the triangular metal dome does not support soldering on the circuit board.
So what is the correct installation method of the triangle metal dome with legs? It is often necessary to install the dome on the FPC/PCB board, so it is necessary to understand the assembly of the triangular metal dome.
1. Use a triangular dome with feet, insert it into the PCB board, and buckle the feet directly. This is the most commonly used method. However, this method also has disadvantages, that is, it is easy to shake during use, and manual operation will be relatively slow.
2. Directly use our commonly used transparent glue to stick the dome. Compared with the previous method, this method may save a lot of labor. Of course, there are also disadvantages. The adhesiveness of this ordinary transparent glue is not very good, it is easy to make the metal dome deviate, and the fixation of the transparent glue is not very good, so it will appear in the process of use.
3. Make metal dome conductive film. This method of making the dome into a conductive film is convenient for pasting. But the cost will be higher than the first two. But no matter in terms of durability or labor, it has advantages over the first two methods. This method is commonly used in mobile phone buttons, remote control buttons, etc.
From the above three assembly methods, you can choose the appropriate design according to your needs. You can also Contact us to obtain more product knowledge. If you have needs for metal dome, you can also contact us for purchase consultation.
