The MTBF of the SMT controller is greater than 572,600 hours (per milhandbook-217-f1).
Touch life: Any point can withstand a touch greater than 50 million times, the cursor does not drift after one correction. Capacitive touch technology is a touch technology that uses the capacitance change that occurs when a finger is approached by a capacitive touch panel.
Capacitive touch has two important capacitance parameters, one is the inductive capacitance between the finger and the upper sensing material (e.g. Ito), and the other is the parasitic capacitance between the sensing material (such as the ITO upper and lower layer) or the sensing material and the optical panel (e.g. Ito and LCD). A parasitic capacitance is generated between the conductor and the conductor, and a change in the inductance capacitance occurs when the finger conductor is close to a sensing conductor of different voltages. The capacitive sensing effect is how to detect 0 under a larger parasitic capacitance (FARAD;PF). A small capacitance change of one or two PF units. Capacitive touch technology is more stable, high reliability, by the body is a capacitive body characteristics, in contact with the touch panel generated by the capacitance changes to achieve the sensing touch effect. Atmel Marketing Director Christopher Ard pointed out that the sensor design can be single-sided Ito graphics for the lowest functional interface, such as single-touch points for large virtual buttons, sliders and other applications, but the more common embodiment is a two-layer design (separate x and Y layers), This requires more complex performance and precision.
