Good design and PCB layout can prevent delays and unnecessary costs of re-designing the PCB. Significant time can be spent focusing on circuit design and component selection while ignoring the importance of good PCB layout, especially for the electrode or trackpad design. Our sensor experts can provide layout review and consultation or hardware design services

With good schematic and PCB layout design, the next step is to fine-tune the electrode to achieve the best performance with the mechanical design, including parameters like threshold, sensitivity, and power modes.
