Key elements to affect the temperature of reflow oven

①Transfer of hot air in reflow soldering

In lead-free welding, we should pay to heat transfer effect and heat exchange efficiency.

Especially for the components with large heat capacity, if they can’t get enough heat transfer and exchange, the heating rate will obviously lag behind that of the components with small heat capacity, then resulting in the transverse temperature difference.

Reflow oven hot air transfer

The design of the air transport structure of the reflow soldering furnace directly affects the heat exchange rate. There are two ways of hot air transfer in reflow soldering. One is microcirculation hot air transmission mode, the other is small circulation hot air.
