The slope resistor that directly affects the gain is generally on the order of 1 m Ω. Optional resistors in the X and Y directions can improve electromagnetic compatibility (EMC) performance and electrostatic discharge (ESD) resistance,
This application guide provides design layout guidelines for the structure and layout of various PCBs (printed circuit boards) (such as FR4,
The blank area can be filled with grounding copper foil (trace width of 6 mil, grid size of 30 mil).
In the previous introduction of the two-layer FR4 PCB, grounding copper foil was used to fill the blank cross-sectional area of the PCB.
Touch buttons can be designed in various shapes, such as square, round, triangular, or other forms. If the PCB size is limited, the designed button shape should maximize space utilization to achieve optimal sensitivity.
The advantage of the touch-state slider is its simple design and high stability in noisy environments.
