    Short Description

    Ultrasonic cylindrical indium coating machine (also known as arc target ultrasonic indium coating machine) is a device dedicated to uniformly coating indium metal on the outer wall of tubular target materials. It is a type of ultrasonic target welding technology and is suitable for indium coating processes of cylindrical materials such as ITO targets, copper tubes, and aluminum tubes. The equipment achieves flux-free welding through high-frequency ultrasonic vibration, replacing traditional manual scraping technology, and is widely used in semiconductors, solar cells, aerospace and other fields.

    Principle

    The ultrasonic generator converts 220V/50Hz mains electrical energy into high-frequency electrical strength (usually 10-38kHz), and converts it into mechanical vibration thru the transducer. The vibration is transmitted to the welding head thru the horn, inflicting the liquid indium steel to produce high-frequency micro-vibration (amplitude of about 20 microns) on the floor of the target. Ultrasonic vibration expels micro-bubbles in the welding area, permitting the indium metallic to fill the microcavity and firmly bond to the substrate barring the need for flux. The welding head strikes alongside the outer wall of the goal to make sure uniform insurance of the indium layer, and the thickness can be managed inside 0.02mm.

    Advantages

    ◆ Flux-free environmentally pleasant welding: Avoid hazardous gases and wastewater produced by means of regular soldering flux, and no extra environmental safety amenities are required.

    ◆ High coating quality: The indium layer is uniform barring blind spots or ripples, has robust adhesion and is now not effortless to fall off. It is appropriate for a range of substances such as copper, aluminum, glass, ceramics, etc., and helps welding of heterogeneous substances such as aluminum-copper.

    ◆ High effectivity and electricity saving: It solely takes 15 minutes (2 vibrations) to coat a copper plate with an region of 1500×190mm, which is an awful lot extra environment friendly than guide work. It saves indium steel utilization and reduces manufacturing charges via about 80%.

    ◆ Wide method adaptability: The form of the welding head (round head, rectangular head, etc.) can be custom-made to meet the desires of special goal materials. Support excessive temperature surroundings (working temperature can attain 350℃), and cooperate with the heating platform to enhance the bonding strength.
