1, pulsed power supply heating method is the use of pulsed current flow through molybdenum, titanium and other high-resistance materials generated when the Joule heat to heat welding. Generally in the heating nozzle connected to the front of the hot dual, the resulting power from the real-time feedback back to the control power supply to ensure the accuracy of the set temperature.
2, the pulse current heating device is an instant heating method, only need to melt the solder when the heating power.
3, the metal has a current through the nozzle when the heat after melting solder. After the solder melts, the power supply is stopped, and the cooling is performed. And the solder is solidified in a pressurized state until a solder joint with high reliability can be obtained.

FPC welding special pulse hot pressing machine advantages:
1, machine work, can improve the welding efficiency, reduce the half of the welding operator;
2, the welding consistency is good;
3, no short circuit, solder joint phenomenon, no floating welding

FPC welding special pulse hot pressing machine features:

The principle of LNR FPC hot press machine
LNR series inverter DC hot welding power is the use of IGBT inverter technology, computer control technology and modern power electronic technology development of new power supply. The principle of the device shown in Figure 1. DC output (Figure 2) to significantly improve the welding process; inverter technology also allows the device has a small, medium and low power consumption, the use of high- (MCU) and the use of electronic technology to make the device with the excellent features of modern equipment, including digital control, monitoring, fault diagnosis and protection, data transmission, equipment, functional, flexible and convenient, Adapt to a wide range. Such equipment is particularly suitable for copper, aluminum and other non-ferrous metal materials, spot welding, alloy materials, spot welding, precision parts spot welding and high-quality products, spot welding.

LNR-02L Inverter FPC hot press features:
1, DC output. Welding current for the pulsating DC (and the waviness of small), no AC zero continuous heating of the shortcomings of the workpiece, heat concentration, improve the thermal efficiency of welding, welding of non-ferrous materials and some difficult welding materials particularly suitable for welding process stability, welding Quality significantly improved. At the same time, the electrode life is extended.
2, by the microcontroller (MCU) control, with temperature monitoring.
3, inverter bridge using soft-switching technology to reduce switching losses and reduce electromagnetic interference.
4, with temperature anomalies, monitoring the value of overrun, network pressure overrun, overheating and other fault diagnosis and alarm.
5, inverter bridge current abnormal automatic shutdown, and enhance system protection.
6, two heating settings, with the temperature slowed down function, a wide range of time settings (0-250ms), for complex welding process needs.
7,20 group parameters stored, easy to use a variety of welding varieties.
8,240x128 LCD display, display a variety of content at the same time.
9, the strong external communication functions: the end of welding, fault, counting signal, RS-232 data communication port, easy to use automatic welding.
10, data storage using EEPROM, no battery life issues.
11, fast response. As a result of a higher inverter frequency (4kHz), power-on time control period of 0.25ms, 20 times than the usual AC welding machine 80 times, control accuracy improved significantly. Compared with the capacitor energy storage welder, no need to charge and discharge, controllability was enhanced, especially for precision parts of the welding and high-quality, high-precision, high-speed welding.
12, the use of advanced temperature control system segment can be set flexibly each section of the heating state of the temperature, time and other parameters can be controlled with high precision.
13, the temperature quickly stable, local instantaneous heating method can well inhibit the thermal impact of the surrounding components.
14, shows the temperature of each stage.
15, thermocouple closed-loop on-line feedback control to improve the accuracy of temperature control.
