Zhongke Micro KEY High-Performance Gas-Phase Welding Fluid: Unleashing the Full Potential of Gas-Phase Welding Technology

Principles and Advantages of Vapor Phase Soldering (VPS) Technology

Vapor-phase welding, also known as condensation welding, is an advanced technology that utilizes the saturated vapor of specialized liquids with high boiling points and excellent thermal stability for welding. Its core principle lies in:

1. Uniform Heating: Saturated vapor generated from boiling liquid uniformly and efficiently transfers heat throughout the immersed PCB assembly, completely eliminating localized temperature variations common in traditional reflow soldering.
2. Low-Oxidation Environment: The vapor layer forms a natural barrier, significantly reducing oxidation of solder joints and components at high temperatures, resulting in brighter, more reliable solder joints.
3. Handling Complex Challenges: Particularly suited for soldering high-density interconnect (HDI) boards, irregularly shaped components, large thermal mass components, or heat-sensitive parts. Its exceptional thermal conductivity consistency effectively prevents issues like warping and cold solder joints.
4. Process Simplification: The entire soldering process occurs within an inert vapor environment, eliminating the need for complex multi-zone temperature settings. This provides a wider process window and simpler control.
   

Vapor Phase Soldering Fluid (VPS Fluid) is the key medium enabling this technology, with its performance directly determining soldering quality, process stability, equipment lifespan, operational safety, and environmental impact.
