Metal Dome Array custom-made

Product model：

GHD240128107

Product launch：

Dec 20, 2019

brief introduction：

The Metal Dome Assembly method can be sorted by 1） w/Feet ，which Direct insert by feet and fix to assemble through the PCB solt 2） w/o Feet , Fix and remove polyester with adhesive and paste it on the PCB . 3）SMT Carrier Assembly ; PANEL PASTE Advantage : not only to improve efficiency ,but prevent the dust from entry products. SMT Carrier Assembly Advantage : To improve and Save space , to make sure small lvolume . " Smaller & Lighter. Density & Better “ which is the primary. vantage of the SMT Carrier Assembly

Product Requirements

	Working Principle : The snap dome is located at the conductive part on the PCB (most of which is above the gold finger on the PCB). When pressed, the central dimple of the dome is concave and contacts the circuit on the PCB , Thus, the circuit is formed, and the current passes through, and the whole product can work successfully . With the help of the conductivity of the metal metal, it plays a role of high-quality switch between the operator and the product. The stable click ratio & longer life-time are used to provide the operator with high-quality tactile feel
Metal Dome Array is mainly sorted by : A. (Transparent) : Convenient to position alignment B. (White) :normally used for Light-guide-film, reflection function C. (Yellow):High-temperature resist material , proceed SMT in the short time D. (Silver Printing):Grounding anti-static effect E. (Black) :normally used for light-block
	Compared with the single paste assembly, the advantages of the whole page paste assembly are more obvious Do not need to add additional procedures, finish the fitting in one step to improve the efficiency Effectively prevent dust from floating the products & causing defects It can improve the utilization of PCB board and reduce the cost of client To make use of the fixture assembly, the work efficiency can be promoted to mini.500 sheet /H.Appro.6~ 10X of single PCS assembly 'S
