metal dome & dome arrays - Best Technology

  What the difference between metal dome with dimple and without dimple? We had knew that metal dome has different types, without dimple and with one or several dimples, but do you know what the difference between with dimple and without dimple?     The biggest difference is the difference in conduction stability, the metal dome with dimple has better conduction stability than no dimple metal dome. Because in the using process, once there are dust on the contact side of metal dome, the no dimple metal dome is surface-surface contacting with PCB pad, and the dust will block the conduction.   For the metal dome with dimple, there are dimple to surface contact with PCB pad, as long as the dust didn ’ t exsit on the dimple, it will not affect the conduction, even the dust is on the dimple as long as you press the dome several times the dust will fall off. So the conduction stability is more better.      Best Technology, as the top 5 metal dome & ...

  As the labor cost increase every year, more and more customer pursue the assembly efficiency of metal dome. So how to increase the assembly efficiency? There are many methods for metal dome assembly, such as the triangle with legs is fixed with the pin hole of the boards, for this kind metal dome we need manually place the dome one by one, the assembly efficiency is very low, cost many labor. triangle-metal-dome-insert-in-PCB And some customer might manually place the metal dome on PCB boards one by one and then stick adhesive tape to fix the dome with PCB board, although save material cost but this methold also has the disatvantage of low assembly efficiency and high labor cost. stick-adhesive-tape-to-fix-the-dome-with-PCB-board Currently the most popular assembly method is customorize a dome array according customer’s PCB boards, put several kinds metal dome or several quantity metal dome on one dome array sheet, customers only need to stick a bo...
