Faster, cleaner splicing Sonobond Ultrasonics claims that its MS-5010B Foil Splicer™ modular system can provide a faster, more efficient weld than ever before; the result of a new solid-state power supply that features automatic frequency control. In addition to the new, improved solid-state power unit, the Foil Splicer™ features a rotating head with a circular welding disk. The Sonobond

unit an ultra-reliable, solid-state metallurgical bond without cracking the glass panels in the photovoltaic cells. The resulting interconnections between the cells produce an array that has sufficient voltage and current to produce a practical source of electrical power. The Sonobond MS-5010B Foil Splicer™ can also be used for fast, clean splicing of aluminium and copper foils. In ultrasonic welding, high frequency ultrasonic energy is directed via a welding tip to the surfaces of the metals to be welded. The energy disperses the oxides and surface films between the work pieces in order to create a true metallurgical bond without melting the materials. Ultrasonic welding is environmentally friendly, produces no waste, and is economical to use.

Draka Communication has announced that it has surpassed the 250,000 km (150,000 miles) mark for sales of BendBright-XS, its bend-insensitive optical fibre, since its introduction in 2006. For perspective, 250,000 km is enough optical fibre to encircle the earth six times. Demand for BendBright-XS is said to have been driven mainly by large-scale deployments of FTTH access networks by the major telecommunications providers in both the US and Europe. BendBright-XSuses a“trench-assisted” index profile to achieve the highest level of bend performance, meeting the stringent industry standard for bend-insensitive fibre, ITU-T G.657.B.

The Sonobond Foil Splicer™ is gaining popularity with manufacturers of solar panels. Ultrasonic welding offers numerous advantages in the production of the photovoltaic (PV) solar cells used to make up solar panels. For example, the bonds have essentially the same strength and structure as their base metals. The welding process is also neat, clean, and economical. Ultrasonic bonding does not require excessive heat, fluxes, filler metals, tapes or other consumables. Solar panel manufacturers use the Foil Splicer™ to weld aluminium strips to the thin conductive metal layer deposited onto the photovoltaic modules.
