Design Hack: Why Your Heater Hates Sharp Corners! 📐🚫

Quick tip for everyone designing their first Flexible Heater:

When you're laying out your heating traces, avoid 90° sharp corners! Always go for Smooth Curves or Rounded Arches.

Why? Two simple reasons:

1. Uniform Heat: Sharp corners create "Hot Spots." Current tends to crowd at the inner corner, which can cause local overheating and even burn through the insulation!
2. Stress Relief: Since these heaters are flexible, sharp angles are where mechanical stress concentrates. A rounded trace distributes the tension, preventing cracks when you bend it.

Pro Tip: Our JLCPCB Flexible Heater Routing Tool makes this easy! Use the Arc/Curve functions to keep your heat flowing smoothly and your heater living longer.
