The nitrogen gas flows more evenly in the lead-free reflow process than in the tin-lead reflow. This reduces the temperature tolerances on the PCB boards and achieves a better soldering effect. 2. Lead-free reflow oven can be used for lead-free reflow, tin-lead reflow, chip aging, and red glue curing. 3.

This temperature must be exceeded by approximately 20°C to ensure quality reflow for every solder joint lead. The amount of time the solder joint is above gun shot drawing effects
