Design guidelines for tenx touch PCB, covering layout, copper pour, and common touch solutions.
This guide provides detailed recommendations for designing tenx touch PCBs, including component placement, matching capacitors, and trace routing. It explains how to position the touch IC, select appropriate resistors and capacitors, and keep sensitive nets short.
Additional sections cover copper pour practices, pad material choices, spring‑PAD and metal‑panel designs, as well as layout tips for LCD‑integrated touch screens. The document is intended for engineers developing touch‑enabled PCB layouts. This manual is written in Chinese.
| Matching capacitor for CLD pin (CTK scheme) | 103 (10 nF) |
|---|---|
| CTK scheme resistor value | 1 kΩ |
| STK scheme resistor value | 220 Ω |
| Recommended trace width for touch nets | 7 mil–10 mil |
| Minimum pad spacing | At least one pad diameter |
| Copper pour clearance to TK traces | ≥1 mm |
Use a 103 (10 nF) capacitor.
A 1 kΩ resistor is recommended.
The trace width should be between 7 mil and 10 mil.
