The pulse heat press machine generates a low-voltage high current using a transformer, which is then rapidly heated through the welding head. The larger the pulse current output, the faster the welding head heats up. Place the workpiece in the fixture, lower the fixture under the welding head, press the start button, and the welding head presses down on the workpiece, initiating heating. The temperature quickly rises and maintains a constant level according to the input parameters. At this point, solder paste reflows, is blown cool, the welding head rises, the solder joints are even, there's no bridging, and the welding is complete.

The heating speed of the pulse hot press is customizable. It utilizes a titanium alloy hot pressing head, which heats up faster, lasts longer, and ensures uniform temperature. The pulse hot press head allows for better temperature control with different voltage adjustments, and the digital pressure gauge ensures the pressure range. During the operation of the pulse hot press, the work surface should be cleaned thoroughly, check for any oil leaks in the oil circuit, preheat before use, with the specified pressure usually around 100-150 Pa and temperature about 100°C. Wait for about 5 minutes before placing the adhesive-coated workpiece into the hot press.

Advantages:

The pulse heat press can reach the desired temperature instantly upon power-on, and it can return to room temperature instantly once the voltage is removed from both ends of the welding head. Moreover, the welding head is flat, ensuring that the appearance of the焊接 products is even and consistent, with minimal instances of poor welds.

Usage:

Pulse heat press machines are used in the production processes of the following products: USB cable welding, soft ribbon FFC and flexible printed circuit (FPC) or rigid printed circuit board (PCB) welding, TCP and PCB or FPC welding, and FPC and PCB welding, etc.
