...Chuno-Chuan Lin; Tsung-Nan Tsai Purpose This study aims to develop a hybrid neural network and linear programming (NN + LP) framework to optimize stencil printing parameters in surface mount technology (SMT) assembly, enhancing soldering quality across multiple quality characteristics (e.g. solder...

... Sn-based solder alloy has not been proposed. This paper aims to address the viscosity issues that must be considered when developing new lead-free solders. Design/methodology/approach A BP neural network model was established to predict the viscosity of the liquid alloy and the predicted values...
