The demands on volume delivery and positioning accuracy for solder paste deposits are increasing as the size and complexity of circuits continue to develop in the electronics industry. According to the iNEMI 2013 placement accuracy for these kinds of components will reach 6 sigma placement accuracy in X and Y of 30 um by 2023.This study attempts to understand the dependencies on piezo actuation pulse profile on jetting deposit quality, especially focused on positioning, satellites and shape. The correlation of deposit diameter and positioning deviation as a function of piezo actuation profile shows that positioning error for deposits increase almost monotonically with decreasing droplet volume irrespective of the piezo-actuation profile. The trends for shape and satellite levels are not as clear and demand further study.

Stereolithography is a handy tool not only for speeding a design to market but also in giving customers an early edge. By allowing a form-and-fit sample to be quickly made from a computer model, stereolithography coupled with simultaneous engineering allows customers to see product models early in the design cycle. And if a picture is worth a thousand words, what's a tangible sample worth?
