Special Solder CERASOLZER

Introduction

Special Solder Cerasolza is the world’s first special solder that can attach to glass.
We provide both Cerasolzer Eco (Pb-free) and a Cerasolzer (Pb-based).

The Cerasolzer series features a special formula and ultrasonic soldering technology that achieve perfect bonding to glass and ceramics.
(*Ultrasonic soldering requires our ultrasonic soldering machine, Sunbonder.)

It achieves bonding to low-solderability materials, such as glass, ceramic substrates,aluminum, tungsten, molybdenum and titanium.
In addition, the cavitation effect of ultrasonic waves activates the molten solder surface and removes the oxide film, flux is not required.

No need for any pre-treatment (vapor deposition or heating) to the substrate surface.
Ultrasonic soldering uses cavitation phenomenom instead of chemical agent (flux).
Suitable for bonding almost all “low-solderability” materials.
Preventing voids.
Different solder melting points are available from 155°C to 297 °C.

Characteristics

Glass-ceramics
bonding
We have made it possible to bond materials that were once thought to be impossible to solder.
Soldering
stainless
steel
Stainless steel can be bonded as if it were a normal soldering process. No welding or other qualifications are required.
Soldering
superconducting
wire
We have made it possible to solder to superconducting wires such as niobium-titanium alloys used in MRI and linear motors.

This product solves these problems

Case (1) Soldering aluminum

Before adoption	Bonding with silver paste requires a drying process, and ACF (anisotropic conductive film) is expensive.
After adoption	Simplified mass production process and reduced the material cost.

Case (2) Fixing prism

Before adoption	Adhesives have been used to fix prisms in single-lens reflex cameras. Yet, there was a problem that the prism moves due to shrinkage when the adhesive is cured . In addition, adhesives deteriorate over time, making it difficult to guarantee long-term quality.
After adoption	By using a special solder Cerasolzer, stable fixing can be done quickly, and the absence of organic materials makes it possible to guarantee long-term quality.

Case (3) Bonding Fiber Optic Ferrules

Before adoption	Fixed by adhesion. Environmental resistance is a concern due to aging.
After adoption	Strong fixation, not affected by aging.

Case (4) Soldering superconducting wires for MRI

Before adoption	Cannot solder.
After adoption	Ultrasonic soldering made soldering possible.

Solderable material

Compatible with low-solderability materials, such as glass, ceramic, stainless steel, and superconductor wire.
