Special solder CERASOLZER


Cerasolzer (Cerasolzer Eco) is the world's first product enabling soldering to glass.
It enables bonding to low-solderability materials, such as glass, ceramic substrates,
aluminum, tungsten, molybdenum and titanium.

We provide both Cerasolzer Eco (Pb-free) and a Cerasolzer (Pb-based).
Please refer to the below product lineup.
Please feel free to ask us for more details.


  • No need for any pre-treatment to the substrate surface.
  • Ultrasonic soldering uses cavitation phenomenom instead of chemical agent (flux).
  • Suitable for bonding almost all "low-solderability" materials.
  • Preventing voids.

Cerasolzer product line up

We present you 18 different types of Cerasolzer, varying depending on melting point, use of lead or lack thereof, line diameter and mass.

Cerasolzer Eco (Pb-free)

Model Unit
Cerasolzer Eco #155 dia1.0mm 150g
Cerasolzer Eco #182 dia1.0mm 150g
Cerasolzer Eco #217 dia1.0mm 1.0kg
Cerasolzer AL-200 dia1.6mm for Sunbonder / aluminum 1.0kg

Cerasolzer (Pb-based)

Cerasolzer #186, dia1.6mm 1.0kg
Cerasolzer #186, dia1.6mm 150g
#297 Cerasolzer #297, dia1.6mm 150g

The model numbers of both Cerasolzer and Cerasolzer Eco are indicated by melting point.. e.g. #186 = 186 degC.
Upon performing soldering test on samples received from customer, we can recommend the most suitable product
for each application. Feel free to inquire about details.

Development history (application, materials)

Main applications
1960s Cerasolzer developed as an answer to an issue of attaching a handle to reinforced glass
Sunbonder developed to correspond with Cerasolzer and ultrasonic soldering technology
1970s Optical fiber connectors
1980s Bonding of CRT filter earthing
1990s Wiring of thin film amorphous silicon solar cell electrodes
2000s External Electrode Fluorescent Lamps (EEFL)

Materials used with positive results: typical metal substrates, glass, ceramics, aluminum, transparent electrode membrane (ITO, ZnO), etc.
Almost all non-organic materials present good results when soldered with this technology.

  • Glass

  • Aluminum

  • Paper-plating solder

  • External Electrode FLuorescent Lamps: EEFL
