Abstract
The present invention provides an aluminum (Al) paste. The Al paste has low cost and high conductivity. An Al powder having a wide range of particle size distribution and an increased solid content are used to solve the problem of multiple pores. A rupture mechanism of alumina is fully used for sintering to improve contacting internal liquid Al with each other for forming conductive paths. With coordination of sufficient liquid glass powder, all ruptured surface of the Al powder is coated to inhibit exposed liquid Al from oxidation on contacting air. The problem of low conductivity of Al paste is thus radically solved.
