The effect of carbon nanotube loading on wettability of solder paste sac 237 and different substrates. International Journal on Advanced Science Engineering Information Technology, 6 (4). pp. 540-543. ISSN 2088-5334 (2016)
Abstract
Wettability of Pb-free soldered surface is one of the main solderability classifications. The aim of this study is to investigate the effect of various percentages of carbon nanotube (CNT) loading (0 – 4%) on the wettability of solder paste SAC 237 and different substrates namely copper (Cu) and tin (Sn). The influence of surface roughness on the wetting behavior was also studied. Both
substrates were undergone a mechanical abrasion process by using four different grit sizes (P240 , P400, P600 and P800) before performing the reflow soldering process using a reflow oven at a temperature of 180°C for 13 minutes. The surface roughness of the substrates was characterized by using a profilometer. Meanwhile, wettability tests were performed by using the optical microscope. Both substrates have shown similar behavior; the rougher surface gives better wettability compared to the smoother one. The wettability of SAC 237 is not significantly affected by the addition of various percentages of CNT. However, CNT loading in the solder paste has shown the different wetting behavior for both substrates.
