Encoder is a kind of electromechanical equipment, which can be used to measure the movement of machinery or the target position of machinery. Most encoders use optical sensors to provide electrical signals in the form of pulse sequences, which can be converted into motion, direction or position information in turn.

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.

The assay for monitoring the content of sulfite ions (SO32−) is essentially important because sulfite has some seriously toxic effects on both environment and human health. For this, a SO32- electrochemical sensor was fabricated utilizing molybdenum disulfide (MoS2) and Nafion. The cyclic voltammetry (CV) and differential pulse voltammetry (DPV) showed that MoS2 had excellently catalytical activity for the redox of SO32-.
