Conductive silver paste is a low-temperature baking conductive silver paste specially designed for resistive and capacitive touch screen circuits. It is made of high-performance resin and silver powder, with good conductivity, and the content of silver particles in the conductive silver paste.
Metal silver particles are the main component of conductive silver paste, and the conductive properties of the membrane switch are mainly reflected by it. The content of metallic silver in the paste is directly related to the conductivity. In a sense, the high content of silver is beneficial to improving its conductivity. But when its content exceeds the critical volume concentration, its conductivity cannot be improved. Generally, when the silver content is 80-90% (weight ratio), the conductivity has reached the highest value. When the content continues to increase, the electrical properties no longer increase, and the resistance value shows an upward trend;
When the content is less than 60%, the change in resistance is unstable. In specific applications, the content of silver particles in the silver paste should not only consider the stable resistance value, but also be restricted by factors such as curing characteristics, bonding strength, and economy. For example, if the content of silver particles is too high, the probability of being covered by the connecting resin Low, the adhesive force of the silver conductor decreases after curing and forming a film, and there is a risk of silver particles falling off. Therefore, the content of silver in silver paste is generally 60-70%  is suitable.
Silver paste is a mechanically mixed viscous paste composed of high-purity (99.9% ) metallic silver particles, binders, solvents, and additives. Conductive silver paste has very strict requirements on its constituent materials. Choose a conductive silver paste manufacturer, SAT NANO has strong scientific and technological strength and is a high-tech enterprise specializing in the research and development, production and sales of conductive silver paste, conductive powder, and conductive paint.
