Inspection of defects in the printed circuit boards (PCBs) has both safety and economic significance in the 4.0 industrial manufacturing. Nevertheless, it is still a challenging problem to be studied in-depth due to the complexity of the PCB layouts and t... see more

The subject of research is the influence of factors of exposure of two-dimensional images on the topology of conductors in the manufacture of printed circuit boards by the method of three-dimensional polymer photomasks. The purpose of the work is ensuring... see more

The implementation of a printed circuit board (PCB) drilling machine using recyclable materials and computer-aided control is presented. A mechanical system using a DC motor for movement on the X and Y axes, and a transmission mechanism by belts, pulleys,... see more

Measurements of the curvatures and warpages of a printed circuit board (PCB) during a thermal solder reflow process using strain gauges are proposed in this study. In the experiments, a shadow moiré is used for measuring the out-of-plane deformations (or ... see more

The use of additive technologies in the creation of soldering masks opens up new opportunities in the production of printed circuit boards, in particular, the use of soldering masks for boards with integrated components. The paper considers the results of... see more

Printed circuit boards (PCBs) have a portentous position in constructing modern electronic equipment. Currently, chemical etching is the process used to produce PCBs at huge volumes, which is not suitable for preparing prototypes. The working environment ... see more

This paper deals with mechanical design and development of high speed digital board (HSDB) system which consists of printed circuit board (PCB) with all electronic components packaged inside the cavity for military application. The military environment po... see more

Electromagnetic Interference (EMI) merupakan persoalan dalam sistem maupun subsistem. Perkembangan produk elektronik dengan menggunakan sistem  desain elektronik digital dan dengan menerapkan komponen  microprocessor bertambah pesat, maka desain... see more

Iodine-iodide leaching and activated carbon adsorption processes for recovery of gold (Au) from waste printed circuit boards (WPCBs) were discussed in this paper. A pressure oxidative acid leaching (POAC) was carried out in an autoclave using diluted sulf... see more
