Dust-free and oxidation-free ovens meet the production requirements of electronic components.

Dust-free and oxidation-free ovens provide critical protection for electronic component manufacturing through a triple-layer safeguarding mechanism. The core lies in the nitrogen protection system, which can stably maintain oxygen levels in the chamber below 15 ppm, reducing the oxidation rate of solder joints in QFN packaged chips during reflow soldering at 260°C to 0.3%—a fourfold improvement in reliability compared to conventional ovens.


Jingyihuang's dust-free and oxidation-free oven adopts a vertical laminar flow design to achieve a Class 100 cleanroom environment. Combined with a ceramic fiber heating module, it effectively blocks 0.1 μm-level dust particles, reducing gold wire misalignment failure rates in LED chip die bonding to 50 PPM. The unique dual-channel deoxygenation system monitors dew point temperature in real time, ensuring the surface tension coefficient of solder balls during BGA ball placement remains stable at 460 mN/m ±5%, significantly improving issues related to solder ball collapse.


For the silver paste sintering process in microwave devices, Jingyihuang's dust-free and oxidation-free oven is equipped with infrared compensation temperature control technology, achieving precise regulation within ±0.3°C. This keeps the fluctuation range of the dielectric loss tangent for dielectric ceramic substrates within 0.001. These technological innovations enable component manufacturers to achieve a general improvement of 12–15% in batch yield rates for high-end products such as 5G filters and automotive-grade MCUs, while reducing annual maintenance costs by over 30%.
