SOLDERING MATERIAL FOR INCREASING DURABILITY OF SOLDERING ZONE SOLDERING METHOD USING THE SAME

摘要

The present invention is to reduce the thermal diffusion rate during the solidification of the solder by inserting the nanoparticles in the soldering site to slow down the solidification rate, thereby brazing material for strengthening the durability of the soldering site that can minimize the occurrence of thermal deformation, cracks, etc. And it provides a soldering method using the same. The brazing material according to the present invention has a small particle size incorporated into the brazing alloy for scattering phonon as a thermal energy carrier generated at a brazing alloy and a brazing alloy mainly composed of lead and tin. The present invention is intended to include phonon scattering nanoparticles having a viscosity, and when soldering using the same, i) a solid solder material containing phonon scattering nanoparticles is used to the soldering site. And soldering the phonon scattering nanoparticles to the joints through the soldering, and ii) applying the phonon scattering nanoparticles to the soldering site of the soldering target in advance and then applying a general Sn-Pb-based or Soldering for the phonon in the soldering material at the junction by performing soldering using a Sn-Ag-based Pb-free soldering alloy There is a method to contain the particles.;Nanoparticles for soldering, thermal energy carriers (Phonon), scattering, and phonon scattering
