The reflow soldering process is an important process to obtain good solder quality. The temperature of the HCH-PCB reflow soldering
machine has 10 temp. zone.We calibrate the temperature to ensure the correct temperature every day.
For the past few years, with the development of electronic products in the direction of small size, light weight, and high density,
reflow soldering is facing great challenges. Reflow soldering requires the use of more advanced heat transfer methods to
achieve energy saving, uniform temperature, and adapt to increasingly complex soldering requirements.
（1） Large temperature gradient, easy to control temperature curve.
（2） The solder paste can be distributed accurately, with less heating times and less possibility to be mixed with impurities.
（3） Suitable for soldering all kinds of high-precision and high-demand components.
（4） Simple process and high soldering quality.
2. Production preparing
Reflow soldering is suitable for SMT, and works with SMT machine. When components are attached to
the circuit board,the soldering needs to be completed by reflow heating.
