| Project Background

The flame retardancy of PCB combustion is a core indicator for ensuring the safety of electronic devices, which is directly related to fire prevention and personal safety. Global mandatory certification systems (such as UL/IEC/GB) require PCBs to pass standardized combustion tests to verify the flame spread resistance of the substrate under high temperature or open flames. With the popularization of halogen-free environmental protection materials and the application of high-density PCBs, accurately monitoring the effectiveness of flame retardants and preventing the risk of carbonization during reflow soldering have become an unavoidable technological need in the industrial chain.

| Project Overview

This project classifies the flame retardancy levels of PCB samples according to core standards such as UL 94 and GB/T 2408 (horizontal/vertical combustion) through key steps such as controllable ignition, measurement of afterflame/afterglow time, and observation of droplet behavior.
