Features of pulse hot press : 1. The advanced segment temperature control system is adopted, which can flexibly set the heating status of each segment.Parameters such as temperature and time can be controlled with high precision. 2. The temperature rises quickly and stably, and the local instantaneous heating method can well suppress the thermal influence on surrounding components. 3. The electrified heating and the power-off cooling are performed at the same time during pressurization, which prevents the joint from floating and welding.It is most suitable for thermocompression welding, solder welding and resin bonding of flexible materials and wires. 4. Display the temperature of each stage. 5. The closed-loop on-line feedback control of the thermocouple improves the temperature accuracy, and the temperature control accuracy is about 3%. 6, welding pressure, welding time, welding temperature can be adjusted precisely. 7, can store 20 sets of welding parameters is very convenient when changing products. 8. Multiple welding points are completed at one time, with high efficiency, good consistency, high welding strength, beautiful welding points, and simple operation. 9,10 million times of welding head life, creating value for your customers. Particularly suitable for welding FPC TO PCB / HSC (Zebra Paper) TO FPC (Flexible Circuit Board) / HSC TO LCD / TAB TO PCB Zebra Strip TAB and other products.
Principle of pulse hot press : 1. The pulse power source heating method is to use Joule heat generated when pulse current flows through high resistance materials such as molybdenum and titanium to heat and weld.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.
