Delicate as silk, the selection of silver palladium paste is perfect!

1、 Pure silver paste: clever use of binder

        Pure silver pasteIt is a commonSilver palladium pasteThe type is characterized by using 3% to 10% lead bismuth borosilicate glass as a binder. After blending the organic carrier and binder into a slurry, sintering is carried out within the temperature range of 500 ℃ to 850 ℃. According to different application requirements, the silver content of pure silver paste can vary between 50% and 85%. It is worth mentioning that pure silver paste with high silver content has a square resistance of less than 2m Ω/mouth, exhibiting good conductivity.

For example, when we need to make highly conductive connectors, we can choose pure silver paste containing high silver content, because connectors, as important components in electronic devices, need to have excellent conductivity. This pure silver paste can ensure that the square resistance of the connector is controlled at a low level, thereby ensuring efficient transmission of the equipment.

However, when choosing pure silver paste, it is also important to note that higher silver content can lead to increased material costs. Therefore, in practical applications, a balance between cost and performance needs to be comprehensively considered.

2、 Silver palladium slurry: palladium participation endows new properties

        Silver palladium pasteIt is based on silver and doped with 2%~5% or 18%~30% palladium element. This slurry forms a dense silver palladium solid solution alloy at a sintering temperature of 850 ℃. Through alloying, silver palladium slurry exhibits characteristics different from pure silver slurry.

For example, silver palladium paste exhibits excellent heat resistance and oxidation resistance in some high-temperature environments. For example, in the manufacturing of power electronic devices, it is often necessary to deal with high temperature environments, and the use of silver palladium paste can ensure that the device can maintain stable electrical performance at high temperatures. In addition, silver palladium slurries with high palladium content typically have a square resistance variation range of 20~70m Ω/mouth.

However, compared to pure silver paste, the cost of silver palladium paste will also increase. Therefore, in practical applications, we need to choose silver palladium slurries with different palladium contents according to specific needs, and weigh performance and cost.

3、 Silver platinum paste: Adding platinum enhances electrical performance

Advanced Institute Technology Silver Platinum Slurry is another type of silver palladium slurry. Compared with pure silver slurry and silver palladium slurry, the platinum content in silver platinum slurry is relatively low, generally less than 5%. Through the sintering process at 850 ℃, the square resistance value formed by silver platinum slurry is usually less than or equal to 4m Ω/port, demonstrating excellent electrical performance.

Silver platinum paste is widely used in semiconductor packaging materials and automotive electronics fields. In packaging materials, silver platinum paste can provide good packaging circuit connections and ensure high-speed signal transmission. In the field of automotive electronics, silver platinum paste can ensure high reliability and durability of electronic components.
