// Thermal PCB Inspection
HotSpotter turns your USB thermal camera into a professional PCB inspection tool. Calibrated temperature readings, real-time thermal imaging, and multi-camera support — all in a clean Windows desktop app.
// Features
Built for electronics engineers who need accurate, actionable thermal data — not consumer gimmicks.
Real-time calibrated thermal imaging from your USB camera. Full-frame streaming with configurable color palettes to reveal temperature gradients the moment you point the camera.
Pixel-accurate temperature measurement at cursor position. Uses proper raw sensor conversion (raw ÷ 64 − 273.15 °C) for scientifically meaningful readouts you can trust.
Works natively with InfiRay A1T, Topdon HT-301 (UVC) and Thermal Master P3 (vendor protocol), with more cameras being added. Plug in your hardware and HotSpotter handles the driver details.
NUC (Non-Uniformity Correction) support for consistent flat-field thermal accuracy. Per-camera lens configuration presets with user-editable profiles stored locally.

An SP4T RF switch in a flip-chip QFN package, with DC current applied through one path to generate localised heating. HotSpotter resolves individual bond pad traces and pinpoints the die hot spot through the package — the kind of measurement electronics labs run every day.

If you work in mechanical engineering, gear manufacturing, or power transmission, you have likely encountered the reference . This standard is fundamental to the design and production of cylindrical gears used across countless industrial applications.
The standard is fundamental to gear manufacturing because it standardizes the shape of the cutting tools (hobs and shaper cutters). If a gear is designed according to DIN 867, it ensures interchangeability and compatibility with mating gears and standard tooling.
