♦Power off

Turn the switch to the off position, and the machine will turn off.

5.Temperature wave setting principle

5.10 what is the heating unit temperature?

the real-time temperature of the heating plate.

5.11 what is oven temperature?

the air temperature between the chain surface and the heating plate.

5.12 what is PCB surface temperature?

the temperature of component soldering feet when PCB is soldered. (the guide

temperature on the soldering wave provided by the solder paste manufacturer

refers to the PCB surface temperature.)

When working, the temperature displayed in the temperature zone on the panel is

the actual temperature of the heating unit, which does not represent the temperature

in the oven and the actual temperature of the plate surface. Therefore, the

temperature displayed will be about 20-40 degrees higher than the temperature in

the oven. The actual use is related to the chain speed, PCB size, thickness, material

and component density.

5.1 Principle of reflow soldering and temperature wave

When the PCB enters the heating zone (dry zone), the solvent and gas in the solder

paste evaporate. At the same time, the flux in the solder paste moistens the pad,
