1. Hot air reflow oven hot air transfer process
In lead-free soldering, we need to pay attention to the loss of thermal efficiency in the transfer process. Especially like some of the large heat capacity components, if the heat is not enough to cause the temperature of the dog days is not enough.
2. Hot air reflow soldering machine heat transfer method
Generally we are using hot air micro-circulation of the heating method, the air outlet against the heating plate hole blowing, so that the hot air in a small range of flow. The design of small circulation due to the flow of hot air concentrated and have a clear direction. Such hot air heating heat transfer effect increased by about 15%, and the increase in heat transfer effect on reducing the size of the thermal capacity of the device will play a greater role in the lateral temperature difference.
3. Hot air reflow oven chain speed control
Chain speed control will affect the lateral temperature difference of the circuit board. Routinely, reduce the chain speed, will give the large thermal capacity of the device more time to warm up, so that the lateral temperature difference is reduced. But after all, the furnace temperature curve is set up depending on the requirements of the solder paste, so unlimited reduction of chain speed in actual production is unrealistic.
4. Hot air reflow oven wind speed and air volume control
We need to pay attention to the process of controlling the wind speed and air volume of the fan speed to minimize the amount of equipment exhaust to enough hot air flow in the furnace to cause an impact. There is also a stability of the equipment, if the equipment is not stable it is easy to jump out of the process window leading to cold welding or original device damage, so we should not forget to test the stability of the equipment in the hot air reflow soldering air speed and air volume control.
