Silicone Keypad Bottom Punctured? Avoid PCB Interference with Proper Escape Clearance DesignJul 30,2026Prevent silicone keypad punctures and PCB damage by calculating escape height ≥ stroke + pill height + 0.2mm. Map all PCB component heights, add relief pockets for tall parts, and use travel limiters. FromRubber DFM review catches interference before tooling.- Silicone Keypad Tolerances: ±0.1mm or ±0.3mm? The Truth About Dimensional AccuracyJul 30,2026Silicone keypad tolerances typically range ±0.1–0.3mm due to cure, batch, and shrinkage variables. Assign ±0.1mm only to critical mating features; use ±0.2mm for general dimensions. Tiered strategy, written sign‑off, and DFM review prevent disputes. FromRubber guides realistic tolerance planning
- Silicone Keypad Hardness Selection: 40 Shore A vs 60 Shore A — How to ChooseJul 30,2026Silicone keypad hardness (40–60A) must match stroke, R‑angle, and usage. Start at 50–55A for most projects. Higher hardness needs PU coating; lower hardness requires longer stroke. Temperature and lifespan affect choice. FromRubber provides DFM hardness recommendations.
