Chengyuan Industry has found in long-term practice that the main reasons for uneven heating during reflow soldering are as follows. The first is the difference in the heat capacity of the components, the second is the marginal influence of the conveyor belt or heater, and the last is the product load.
1 In reflow soldering, the conveyor belt continuously conveys products, and this process also transmits heat. The heat of the heating center is different from the temperature of other parts, and the processing temperature will be different.
2 The amount of product reprinting is unreasonable. The use of reflow soldering should consider the length and spacing of PCB, and the loading amount will affect the processing effect
To achieve a better temperature processing effect, continuous testing is required.
