Following the recent development of densely populated boards, it is essential to improve the quality of high-density mounting, such as the application of minimal components represented by the 0402 metric package, also known as 01005, filletless mounting, and narrow pitch mounting.
On the other hand, there have been reductions in joint strength, due to extremely small pads and solder volumes, caused by narrowed components and land, as well as filletless mounting. Therefore, using a ductile alloy that is compliant with narrow pitch mounting of micro components and an excellent solder paste with stable printing and reflow characteristics is a requirement.
SN100C P520 D5 Lead-free Solder Paste with the compliant SN100C alloy reduces shrinkage defects, slows the intermetallic growth, and offers high impact strength for 0402 components. Additionally, the paste provides excellent reflow with minute solder volumes, excellent wetting on all common substrates (including nickel and brass), minimal cracking of flux residue, and good hot slump performance
