T9 Ultra-Fine Solder Paste-FTP-305

T6, T7, T8, T9, and T10 solder powder are called ultra-fine solder powder because of their small particle sizes. Solder paste consisting of T6 to T10 solder powders is called ultra-fine solder paste. With the continuous development of the microelectronics and semiconductor industry, the chip size is getting smaller while the packaging density is getting higher. It's hard to meet the requirements of microelectronics and semiconductor packaging with traditional solder paste products of T4 and above. Currently, the solder paste used in packaging is increasingly being "ultra micronized".
