The features of the machine 1.used the Europe lines. 2. small size more easy to operate. 3.adopt Japan piezoelectricity ceramic converer,output power more strong and stable. 4.especially for SD card,U disk, headset,communications and other microelectronic products welding Function 15kHz and 20kHz ultrasonic welding machine will damage the internal chip in high precision electronic components when welding,But 35kHz welding machine can solve this problem, welding more precision.
