This article will delve into the main material components and their functions of thick film resistor paste, and present the findings of Advanced Institute (Shenzhen) Technology Co., LtdYB5301 thick film circuit resistor paste from Yanbo brandProvide an example for illustration.

（1） Basic composition of thick film resistor paste

Thick film resistor paste is usually composed of three parts: conductive particles, glass powder, and organic carrier. These three factors work together to determine the performance and application effect of the slurry.

1. Conductive particles

Conductive particles areThick film resistor pasteThe core component of the resistor is responsible for improving its conductivity. Common conductive particle materials include metals (such as silver, palladium, etc.), metal oxides (such as ruthenium oxide, etc.), etc. These materials have good conductivity and chemical stability, and can form stable conductive phases during high-temperature sintering processes.

In the YB5301 thick film circuit resistor paste of the platinum brand, conductive particles are carefully selected and proportioned to ensure excellent conductivity and stability of the resistor body. The specific ratio varies depending on product specifications and performance requirements, but is generally controlled within a certain range to achieve the best results.

2. Glass powder

Glass powder plays a role in bonding, fixing, and protecting conductive particles in thick film resistor paste. It can melt and encapsulate conductive particles during high-temperature sintering, forming a stable resistor structure. At the same time, glass powder can also adjust the resistance value, improve the mechanical strength and chemical corrosion resistance of the resistor.

In addition, the glass powder also has a low melting point and good flowability, which helps to reduce sintering temperature and improve production efficiency.

3. Organic carrier

Organic carrier is the liquid component in thick film resistor paste, responsible for uniformly dispersing and bonding conductive particles and glass powder together to form a printable paste. Common organic carriers include resins, solvents, etc. They need to have good dispersibility, adhesion, and leveling properties to ensure that the slurry can be evenly coated on the substrate during the printing process.

The organic carrier in the YB5301 thick film circuit resistor paste of Yanbo brand has been specially formulated to have good printing performance and stability. It can maintain the uniformity and consistency of the paste during the printing process, ensuring that the resistor has a good appearance and performance.
