Microcrystalline glass silver paste

Microcrystalline glass silver paste is widely used in fields such as solar cells, electronic components, sensors, etc. In solar cells, microcrystalline glass silver paste is used to print on the front and back of silicon wafers, forming gate line electrodes to improve the conversion efficiency and stability of the cell. In addition, microcrystalline glass silver paste also plays an important role in conductivity and connection in electronic components and sensors.

Product Features

Excellent conductivity: Silver powder as the conductive main body ensures that the microcrystalline glass silver paste has excellent conductivity.

Good bonding strength: The addition of microcrystalline glass powder improves the bonding strength between silver paste and substrate materials (such as silicon wafers, ceramic wafers, etc.), preventing cracking of the metal film layer after sintering.

Adjustable thermal expansion coefficient: The thermal expansion coefficient of microcrystalline glass powder can be adjusted to match different matrix materials, reducing the problem of detachment or cracking caused by thermal stress.

Good thermal stability: Microcrystalline glass powder has good thermal stability over a wide temperature range and can adapt to various high or low temperature working environments.

Preparation process

Raw material preparation: Prepare silver powder, microcrystalline glass powder, inorganic binder, organic binder, and additives in a certain proportion.

Mixing and dispersion: Mix various raw materials together and perform sufficient dispersion treatment to ensure uniform distribution of each component.

Grinding refinement: Refining the mixture through grinding equipment to improve the uniformity and fineness of the silver paste.

Blending and molding: silver paste is blended and molded according to specific needs to meet the production requirements of different products.
