Target bonding is a technical method that binds a target material to a substrate, additionally recognized as target welding. In current years, ultrasonic target bonding technological know-how has emerged as a new target bonding method. This technology affords an environmentally pleasant welding solution that does no longer use flux, basically warding off the a number issues of traditional flux welding techniques, as a consequence offering secure and dependable welding. Its benefits are regularly turning into obvious in the subject of target bonding.
Why is flux now not needed when the use of ultrasonic technological know-how to bond the target material?
An ultrasonic generator converts electric powered current into high-frequency electrical energy. This transformed high-frequency electrical power is then transformed into mechanical action of the equalfrequency by using a transducer, producing tens of hundreds of high-frequency vibrations per second. This high-frequency vibration, attaining a positive amplitude, transmits ultrasonic electricity to the soldering vicinity thru an amplitude transformer. The high-frequency vibration reasons the oxide layer in the soldering vicinity to peel off, and microbubbles are expelled. At the identical time, the goal fabricenters the microcavities occupied with the aid of these microbubbles, firmly bonding the target materials to the substrate, hence accomplishing soldering besides the use of flux.
What are the benefits of ultrasonic targetl bonding technological know-how in contrast to normal flux welding methods?
1.No flux is used: Flux can create microbubbles interior the solder joint, which can motive soldering defects such as cracks over time. Ultrasonic technology does now not use flux in the course of the soldering process, for that reason keeping off innovative corrosion prompted by using flux residue in the soldering area.
2.Environmentally pleasant welding solution: Ultrasonic welding technology does no longer use flux, so there is no want for gas emission amenities and wastewater treatment system to deal with hazardous gases generated by means of flux.
- The coating is firm and will not peel off.
- The coating is uniform, without blind spots or ripples.
- Reduced production costs: The elimination of fluxing and flux cleaning processes significantly reduces equipment and production costs, and can improve productivity by simplifying the welding process.
- Improved production efficiency: Coating a 1500*190mm copper plate takes only 15 minutes (2 vibrations). Coating a 50*50mm ITO glass plate takes only 1 minute (3 vibrations).
- Helping to develop new products: Traditional flux welding methods cannot weld materials, but ultrasonic technology can be used to bond materials that are difficult to weld, thus enabling the development of new products.
Ultrasonic target bonding equipment, due to the fact the most frequent target materials bonded is indium, is additionally known as an ultrasonic indium coating laptop or ultrasonic indium utility machine. Manual indium coating has enormous drawbacks: firstly, the indium coating is uneven, affecting the overall performance of the covered material; secondly, the guide scraping approach consequences in a vulnerable coating that without problems peels off; thirdly, guide scraping is very inefficient and labor-intensive; and finally, indium metallic is wasted due to unsuitable managing or different reasons. Ultrasonic indium coating technological know-how correctly solves these problems. For substrates of one of a kind shapes, ultrasonic indium coating machines can be used for surface coating of planar targets, internal round targets, and outer round targets, changing the out of date guide scraping technique.
