Principle of pulse hot press , hot press welding machine : 1.Pulse power source heating side is widely used in wire compression welding, solder reflow, IC chip. Adopt temperature stage control and time control to meet different welding needs, such as: flat cable thermocompression bonding and ACF bonding for LCD, touch screen, resin thermocompression bonding for relays, printers, glasses, etc., CCD for mobile phones and digital cameras , CMOS solder joints, solder joints of flat cables such as computers, USB, and FPCs in cameras, solder soldering of enameled wires such as hard disk drives (HDD), and manufacturing of household appliances such as DVD and AV equipment. The formula is a method of heating and welding by using Joule heat generated when a pulse current flows through high resistance materials such as molybdenum and titanium. Generally, a hot couple is connected to the front end of the heating nozzle, and the generated power is fed back to the control power in real time to maintain the correctness of the set temperature. 2. The pulse current heating device is an instantaneous heating method. It is heated only when the solder needs to be melted.

3. The metal welding nozzle melts the solder after heating when the current passes. After the solder is melted, the current is stopped and cooling is performed. In the pressurized state until the solder is solidified, it is possible to obtain highly reliable soldering without soldering or floating.
