    [What is the working principle of Hotbar welding machine]

    Views: 175 times Release date: 2018-1-6 17:11:15

    The principle of HotBar (hot-melt soldering) is to first print the solder paste on a circuit board (PCB), and then use the heat to melt the solder and link the two electronic components that need to be connected. Soft board (FPC) is usually soldered to the PCB, so it can be light, thin, short and small. In addition, the cost can be effectively reduced because one or two FPC connectors can be used less.
    General HotBar hot pressing and its principle are to use the electric heat generated when pulse current flows through materials with high resistance characteristics such as molybdenum, titanium, etc. to heat (thermodes / heater tip), and then heat and melt the PCB Solder paste to achieve the purpose of soldering. The control of the pulse current is very important. The control method is to use the thermocouple circuit at the front end of the thermal head to feedback the instant thermal head temperature back to the power control center to control the pulse current signal guarantee. Correctness of temperature on the thermal head.
