1. Heating mode is "upper circulating hot air + lower infrared hot air". It is equipped with three forced cooling zones.
2. Upper heating adopts microcirculation heating method, which can achieve large heat-air exchange and has very high heat exchange rate. It can reduce the setting temperature in the temperature zone and protect the heating elements. It is particularly suitable for lead-free welding.
3. Microcirculation heating mode, vertical air blowing and vertical air collecting can solve the problem of dead angle when using guide rail in reflow soldering.

The componnetn is brought to a temperature of at least 240C for soldering. Using a saddle profile the board is gradually heated in line with pre-defined, individual temperature ranges. Even components with differing thermal masses are heated homogeneously and temperature differences mimimised.
With a linear profile, the component is not heated in a stepped manner during soldering, in fact it is heated along anidentical linear temperature gradient. Linear profiles can reduce cycle times andcan help to reduce soldering errors suchas tombstoning.
The Process of Reflow Oven
The reflow oven process is that when the circuit board with printed solder paste and good components enters the reflow oven furnace, the circuit board is driven by the reflow oven rail transport chain to pass through the preheating zone, heat preservation zone, soldering zone and cooling zone of reflow oven in turn After the temperature changes of the four temperature zones of reflow oven, the reflow oven process of the circuit board is completed. The following specifically explains the soldering change process when the circuit board passes through the four temperature zones of reflow oven in sequence.
