Soft circuit introduction is a kind of multi-layer plane circuit panel which is made up of spring conducting material and insulating material. It can be separated into silver paste circuit, carbon paste circuit and combined circuit of the two.
Membrane circuit can form membrane switch with membrane panel and can also be used as single circuit layer. Technical Parameters: Switch Power<1W Loop Impedance<100Ω Working Voltage<42VCD/25VAC Working Environmental Temperature: -40℃--+50℃ Working Current<100MA Keystroke Force:1-5N Insulating Impedance:≥100MΩ Lead/Wire Width 1.27mm, 0.5Ω/cm Relative Temperature: 40 Service Life Sensed Keystroke≥200,000times Senseless Keystroke≥1,000,000times Max. Mechanical Load Capacity: Give 100N of operating force in switch center of the keyboard for 60±5s. Then the loop impedance is 100M and insulting impedance is 100M. Touch Instability time: Jitter time is shorter than 5ms in the moment when contact point of the switch is turned on or off. Voltage Resistance: Voltage resistance between bordering leads on the down-lead band or between turned-off contact points should be no lower than 250VAC and the time period is 1min. Center-distance between bordering leads on the down-lead band is often 2.54mm. Using Requirement: The article on which the circuit is to be fixed should have flat surface and no rust and the circuit can be fixed only after the article is cleaned by alcohol or gasoline. Transportation: Membrane switches packaged into bags can be transported with any kind of transporting tools when exempt being poured by rain and snow. Storage: Membrane switches packaged into bags should be stored with the temperature being -15℃-35℃, relative humidity not higher than 80% and no acid, alkali or other caustic articles in the surrounding air. |
