Common Remote Control Dome Issues and Solutions
| Issue | Cause | Soluzione |
|---|---|---|
| Key unresponsive | Oxidation/contamination on the metal dome or PCB contact point | Clean the contact point; use gold-plated/silver-plated metal domes for enhanced anti-oxidation |
| Key insensitive | Excessive contact resistance; metal dome not fully depressed | Check dome height vs. PCB gap; use center-point gold-plated domes to lower resistance |
| Feel becomes too hard/soft | Metal dome fatigue deformation; force value outside tolerance | Optimize dome curvature design; tighten force tolerance to ±15gf |
| Dome doesn't rebound | Housing deformation, foreign debris jamming, or dome fracture | Inspect housing structure; use high-durability SUS301 material rated for ≥1,000,000 cycles |
| Intermittent performance | Dust/oil contamination entering the gap between dome and contact | Use TPU or PET film encapsulation to seal out external contamination |
| Short lifespan, early failure | Inferior material or burrs on stamped edges | Use precision full-cut, burr-free metal domes; 100% electrical performance testing on all batches |
