Ceramic Substrates Welding

Ceramic Substrates Welding – Ultrasonic Soldering Iron – Cheersonic

Ceramic substrate refers to a special process plate where copper foil is directly bonded to the surface of alumina or aluminum nitride ceramic substrate at high temperatures. The ultra-thin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent Soldering performance and high adhesion strength, and can be etched into various patterns like PCB board, which has great current carrying capacity. Therefore, ceramic substrates have become the fundamental material for high-power power electronic circuit structure technology and interconnection technology. The uses of ceramic substrates include high-power power semiconductor modules; Semiconductor refrigerators and electronic heaters; Power control circuit, power hybrid circuit. Intelligent power module; High frequency switching power supply, Solid-state relay. Automotive electronics, aerospace and military electronic components. Solar panel components; Telecommunications dedicated switch, receiving system; Industrial electronics such as lasers.

The tip of ultrasonic soldering iron vibrates at ultrasonic frequencies. This vibration induces cavitation in the molten solder, which breaks up and removes oxides and promotes wetting. Ultrasonic soldering iron enables the easier joining of hard-to-solder materials which are known as impossible or difficult to be soldered in conventional soldering. Eco-friendly soldering is achieved by fluxless soldering and no post treatment to remove flux. The ultrasonic soldering technology is widely used in ceramic substrates. The ultrasonic soldering iron of Cheersonic produces high quality soldered joints. Using the solder alloy, can easily solder directly to glass, ceramics and other low solderability materials.
