Applications:
- Disk drives
Regardless of the hard disk, or diskette, is very dependent on FPC high softness and thickness of the 0.1 mm slim, read data finish quickly. Either a PC or NOTEBOOK. - Computer and LCD screen
Use the one line configuration of flexible circuit boards, and thin thickness. The digital signal into the picture, through the LCD screen - CD player
Focuses on three dimensional assembly characteristics of flexible circuit boards and thin thickness. The huge CD to carry around - The mobile phone
Focuses on the flexible circuit board light weight and thin thickness. Can effectively save the volume of products, easy connection of the battery, microphone, and buttons and into one. - The latest applications
Hard disk drives (HDDS, hard disk drive) of suspended circuit (Su ensi. N cireuit) and the components of xe packaging board, etc
Environmental:
Storage Temperature: -40°C (-40°F) to +70°C (158°F).
Storage Altitude: Sea level to 35,000 feet.
Operating Temperature and Altitude: -30°C (-30°F) to +75°C (170°F). Can be
designed to operate in most environments.
Humidity: No delamination after 24 hours at 80°C and 90%RH.
Features:
- high quality and low price
- long durability and lifecycle
- strong ability of Anti electrostatic interference performance
- metal dome could provide good tactile
The keys of the graphic overlay are embossed, the metal dome is embedded in the circuit layer, and there is a retainer covering the metal dome. The appearance of this kind of membrane switch is stereoscopic. When you press the keys, there is a strong tactile feeling and the time of the keys snap-back is very short. There is no need for the operator to judge whether the switch is turned on by the sound signal or indicator lights given by the machine.
