What makes vapor phase reflow different from conventional convection reflow?
Conventional reflow ovens heat the board from the outside in, which can create temperature variation across different areas of the board. Vapor phase reflow surrounds the entire board in a controlled vapor medium, delivering the same temperature to every component simultaneously regardless of size, density, or location on the board.
Why does uniform temperature distribution matter for soldering?
Uneven heat during reflow can result in cold joints, tombstoning, or thermal damage to sensitive components. Because vapor phase keeps temperature consistent across the whole board, those risks are significantly reduced, which is especially important for dense or complex assemblies.
Is vapor phase reflow better suited for certain types of boards?
It is particularly well suited for boards with fine-pitch components, mixed component sizes, or high-reliability requirements. It also performs well with leadless solder bases, which require higher melt temperatures and are more susceptible to overheating with conventional methods.
Does vapor phase reflow work with standard lead-free solder?
Yes. Vapor phase reflow is compatible with lead-free solder and is actually one of the better methods for handling it, since lead-free alloys require higher reflow temperatures where precise thermal control matters most.
Is vapor phase reflow available for prototype quantities or only larger runs?
It is available for prototype builds at Ninja, not just production runs. Since we use vapor phase as part of our standard SMT assembly process, you get the benefits of this technology regardless of your order size.
