General Information
CERASOLZER is used in manufacture of electrical parts, to contact electrical / electronical materials and flat glass / metalized glasses because it provides a unique bonding technique that can take the place of commonly used silver baking, indium soldering,molybdenum-manganese and resin (flux) bonding methods.
Glass, Ceramic, Aluminum and Stain-less Steel are commonly known as non-solderable materials with con-ventional soldering systems. Heating is not enough to overcome this obstacle.
Ultrasonic vibrations in conjunction with heat cause the required effect and delivers the technical break through.
This principle is based on the scienti-fically recognized "Ultrasonic Cavi-tational Phenomenon" which is caused by strong ultrasonic penetration.
The active-solder alloy抯 CERASOLZER together with an ultrasonic acti-vated soldering system enables to solder on 慼ard-to-solder� materials flux free.

Adhesive Mechanism
There are different targets, which can accomplished by using ultrasonic energy in a pool of molten solder on a substrate:
1. The oxides can be removed from the substrate permitting the solder to react with the substrate, i.e. bond.
2. The liquid metal can be forced into the tiny crevices, cracks and micropores of the substrate and thereby seal them and provide a greatly increased surface of the solder for bonding purposes.
3. The ultrasonic vibration presses out gas bubbles of the liquid solder and produces a shrink hole free joint. This is very interesting for applications in high-vacuum.
CERASOLZER contains a small amount of elements such as Zn, Ti, Si, Al, Be and Rare Earth, which have a strong chemical affinity with oxygen. These metals are thought, during the bonding process, to combine with oxygen in air to form oxide, which is chemically bound to the surface of glass, ceramic etc
