Metal Dome Array & metal dome sheet   The Metal dome array (key dome array) is the most effective solution for a simple switch with a superior tactile interface between your equipment and the user. A metal dome array is a kind of PET sheet that carries metal dome contacts. It is applied to PCBs to function as switches of mobile phones and electric home appliances. Compared to the membrane polyester switch which was formerly used, it gives good click-feeling. It also gives much longer  life span compared to poly dome sheets. It also takes place of down going productivity of tact switches with its potential productivity.   Metal dome contacts on the sheet/array are positioned over the contact point of PCBs. When a dome is pressed, the center of it contacts to the PCB and let the electric current flow through. This is how metal dome arrays work.   Characteristic:   Suitable for keys on all types of electronic equipment Also available in very thin design Upper circuit made of conductive inks, metal dome Non-conductive layer (Spacer) Adhesive at both upper sides   Mechanical/ Electrical properties: Life expectancy: 1 million cycles Dimensional tolerance: +/- 0.15mm Dimensional stability: +/- 0.15mm Contact bounce: 0.5~10ms Operating condition: -30 to +85 degree Celsius, 50 to 80% RH Storage condition: -40 to +85 degree Celsius, 10 to 80% RH   Advantage:  A uniformity click feel, nimble feel, A low cost and a short term of R&D, Higher confront face each other than change market, Very good for fit to small and slim size because practical use for thickness & space of products, Not necessary to specify soldering at that time of product assembly, Environmental and cut troublesome of repair parts Low work’s error rate than tact switch type Customers’ designs and special specifications are accepted   ACTIVATE works very closely with its customers in order to insure the success of its projects. Working on the customer’s drawing, the Research and Development Department offers specific solutions that meet your needs.    Further information is available at http://www.adv-cn.com or http://www.metaldome.com.cn .
