EW-1050MC-N2 Reflow
The EW-1050MC-N2 is a large ten-zone lead-free nitrogen reflow oven from a China SMT machine manufacturer for high-volume PCB assembly. This SMT reflow oven heats boards by forced convection with air or nitrogen across ten top and ten bottom zones, up to 350 °C, on a standard 500 mm wide conveyor.
Key Features
- Ten top and ten bottom heating zones with independent closed-loop control via Siemens temperature modules and SSR drive, up to 350 °C
- Air or nitrogen forced convection for lead-free profiles on 0201, 0402 and ultra-small fine-pitch SMD components
- Three conveyor modes (mesh belt, pin chain rail, or both in parallel) and three control options (PC, touch panel, or dual) with Siemens PLC and genuine Win10
- Rectified jetting heating for strong heating power and excellent temperature uniformity
- Two-zone top/bottom air cooling with adjustable wind speed, convertible to water cooling
- External flux recovery unit with two independent recovery zones, easily removed for quick maintenance
- Conveyor speed 0-2000 mm/min on a 500 mm wide 316L stainless steel belt; smart software with online programming, daily logs, zone charts, reports, alarm records, zone shut-off and dual safety control

SMT Industry News
AI server boards and high-end computing PCBs are driving strong demand for SMT capacity and precise process control, and lead-free soldering leaves a narrow process window that reflow ovens must hold exactly. Market researchers forecast continued growth of the global SMT equipment market through 2032, while MES connectivity and real-time process data spread across smart factories. An oven that logs zone temperatures, generates daily charts and records alarms fits directly into such data-driven SMT production lines.
Applications
The EW-1050MC-N2 suits high-volume lead-free PCB assembly in consumer electronics, communications, automotive electronics, LED lighting and industrial control. Its ten-zone heating and nitrogen capability handle fine-pitch 0201 and 0402 boards, BGAs and double-sided assemblies in a full SMT production line. As a nitrogen reflow oven from a China SMT machine manufacturer, it combines throughput, profiling flexibility and low operating power.
