Method for modifying SAC/Cu welding spot interface by using nano Cu6Sn5 phase and detecting SAC/Cu welding spot interface
According to the method for modifying the SAC/Cu welding spot interface through the nanometer Cu6Sn5 phase and detecting the nanometer Cu6Sn5 phase, nanometer Cu6Sn5 particles are firstly prepared, then Sn3. 0Ag0. 5Cu and the nanometer Cu6Sn5 particles are evenly mixed, then ultrasonic concussion is...

| description | According to the method for modifying the SAC/Cu welding spot interface through the nanometer Cu6Sn5 phase and detecting the nanometer Cu6Sn5 phase, nanometer Cu6Sn5 particles are firstly prepared, then Sn3. 0Ag0. 5Cu and the nanometer Cu6Sn5 particles are evenly mixed, then ultrasonic concussion is further conducted, the Sn3. 0Ag0. 5Cu-Cu6Sn5x welding flux alloy is more evenly mixed, and the modified Sn3. 0Ag0. 5Cu-Cu6Sn5x welding flux alloy is obtained. The method comprises the following steps of: removing surface oxides from a PCB (Printed Circuit Board), then mounting a Sn3. 0Ag0. 5Cu-Cu6Sn5x alloy on a PCB substrate, then carrying out reflow soldering treatment, and then carrying out aging treatment. On the basis that the original performance of the solder is not changed, the Sn3. 0Ag0. 5Cu lead-free solder is enhanced through the nano Cu6Sn5 phase, growth of an IMC layer is inhibited, and the reliability of a welding spot can be effectively improved.
