Schematic
Seltech offers schematic review and consultation in order to avoid the most common errors including capacitive sensing electrode, power and grounding, critical design errors, optimized value of passive component, etc. Our assistance can speed up the design schedule prior to the PCB layout.

Layout support
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

Electrode calibration
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.

Performance optimization
Test and qualification are the last steps to finalize the design. To help fulfill internal design goals, Seltech can provide support during pre-compliance for both Contact Discharge and Air Discharge according to the IEC61000-4-2 standard.
