High-Temperature Tunnel Oven (Vacuum Reflow Type)
The high-temperature tunnel oven (reflow type) is a continuous vacuum reflow system designed for precision soldering and high-temperature thermal processing. It integrates infrared heating, forced hot air circulation, and vacuum technology to ensure stable temperature profiles, low void rates, and high product reliability. The system is suitable for cleanroom environments and high-end electronic manufacturing.
Applications
Reflow soldering for electronic assemblies
Semiconductor and IC packaging
PCB and hybrid circuit processing
Optical and LCD module manufacturing
Precision components requiring high-temperature and clean processing
