Ultrasonic Welding Plays Key Role in Photovoltaic Cell Manufacturing
WEST CHESTER, Pennsylvania, April 3, 2007 -- With concerns about global warming and rising energy prices driving more businesses and consumers to consider alternative forms of energy, Sonobond Ultrasonics' MS5010B Ultrasonic Foil Splicer has seen increased interest from some of the world's leading solar panel manufacturers.
"The Foil Splicer welds the aluminum interconnects between the photovoltaic cells to boost voltage and current," explains Janet Devine, president, Sonobond Ultrasonics." The equipment delivers mechanical vibratory energy under pressure to create ultra-reliable, solid-state mechnical bonds."
Ultrasonic bonding has a number of benefits over other methods of bonding. The bonds created by the Foil Splicer have essentially the same strength and structure as their parent materials. The higher frequency operation avoids cracking of the glass panels in the photovoltaic cells and does not distort materials. It's also faster than other splicing methods.
