Superior Insulation for Electronic and Ceramic Applications

Designed for the demanding needs of the electronics industry, this insulating paste delivers outstanding performance as an interlayer in thick film circuits and PCBs. Its high resistivity and dielectric strength guarantee electrical insulation, essential for reliable electronic device assembly. Compatibility with a wide range of substrates enhances its versatility, while lead-free, non-toxic properties meet environmental and safety standards.

Efficient Application and Curing Process

The pastes viscous form ensures smooth screen printing, providing a consistent insulating layer on ceramics, metals, and glass. Pre-drying at 120C for 510 minutes accelerates handling and firing preparation, while final curing at 850900C secures optimal properties. Organic binders and ceramic dielectric fillers establish durable insulation without hazardous ingredients.

FAQs of Insulating Paste for Screen Printing:

Q: How is insulating paste applied in screen printing processes?

A: The paste is screen-printed directly onto electronic or ceramic substrates, such as alumina, metals, or glass. After application, the layer is pre-dried at 120C for 510 minutes and then fired at 850900C to achieve full insulation properties.

Q: What benefits does this paste provide for circuit and PCB manufacturing?

A: This insulating paste creates a high-resistivity dielectric barrier, helping prevent electrical leakage and improving device reliability. Its strong dielectric strength ensures insulation even in high-voltage applications, making it ideal for thick film circuits and PCB manufacturing.

Q: When should the insulating paste be fired to achieve optimal results?

A: After screen printing and pre-drying for 510 minutes at 120C, the paste must be fired at a curing temperature between 850900C. This process solidifies the insulating layer and ensures ideal electrical properties.

Q: Where can this insulating paste be used?

A: It is suitable for electronic assembly, thick film circuit fabrication, and ceramic substrate insulation on surfaces like alumina, ceramics, glass, and metals. Its versatility enables use in both industrial manufacturing and specialized electronic applications.

Q: What is the recommended storage procedure to maintain shelf life?

A: Store the unopened paste containers in a cool, dry place with the lids tightly sealed. Under these conditions, the product retains its properties for up to 12 months as indicated on the packaging.

Q: Is this paste safe to use and environmentally friendly?

A: Yes. This product is lead-free, non-toxic under normal use, and has mild odor, ensuring it complies with modern safety and environmental standards applicable in industrial and electronic production settings.

Q: Why is this paste classified as a specialty product for electronics?

A: Its proprietary blend of ceramic dielectric fillers and organic binders, combined with high electrical resistivity and dielectric strength, positions it as a specialized paste ideal for advanced insulation in electronic applications.
