Shenzhen Yichun Electronic Automation Equipment Co., Ltd., founded in 2013, is a practical SMT production line solution provider and integrator focused on helping electronics manufacturers build stable and efficient manufacturing lines.
We specialize in SMT line planning, equipment integration, installation, and technical support based on real factory production requirements. Our solutions combine reliable SMT equipment with practical engineering experience to deliver cost-effective and easy-to-operate production lines for growing manufacturers.
Our main solutions include IR reflow ovens, wave soldering systems, SMT production lines, automatic printers, pick-and-place machines, and related peripheral equipment. Rather than focusing only on individual machines, we emphasize complete line configuration, factory layout optimization, and long-term operational stability.
Yichun Electronic operates a demonstration and training showroom used for equipment testing, solution verification, and customer visits, helping clients better understand production processes before implementation.
Our solutions are applied in consumer electronics, industrial control, communication products, and automotive electronics. We have supported SMT line projects in regions including Southeast Asia, South Asia, and Eastern Europe, providing installation, technical assistance, and ongoing service support.
Understanding heat transfer mechanics, radiant flux optimization, and closed-loop thermal stability in modern Surface Mount Technology (SMT).
Infrared reflow ovens leverage medium-to-far wavelength IR radiation (1.5 µm to 6 µm) emitted from ceramic or quartz panel heaters. The thermal energy directly interacts with molecular bonds within solder pastes (SAC305, Sn63Pb37) and PCB substrates, achieving ultra-rapid energy transfer without relying exclusively on air motion.
To mitigate shadowing effects on high-density PCBs containing BGA, QFN, and 0201 components, modern IR reflow systems incorporate forced hot air micro-convection. This hybrid approach guarantees micro-zone uniformity, preventing component warping while maintaining a minimal Delta T (ΔT ≤ 2.0℃) across complex assemblies.
Integrating controlled Nitrogen (N2) atmosphere injection reduces oxygen content below 100 PPM within the peak reflow zone. Decreasing oxidation significantly improves surface tension during solder wetting, reducing intermetallic voids to under 5%—critical for high-reliability automotive and aerospace hardware.
