What is the spreading rates? and, how to calculate the spreading rates of lead free solder alloy drop on substrate??

05 May 2017 1 9K Report

for related researchers, it is important to learn the relationship between contact angle and spreading rates.

Dear Mr. Erer,

Please find attached the paper by Nicolas Eustathopoulos . In this paper he difined the spreading rate as dR/dt, where R is a drop base radius measured upon a sessile drop test and t is of course a time of test.

Best wishes,

Wojciech
