Describes the process of improving and developing tools in computer‑aided design system Delta Design. Currently, the modern  process of PCB development is quite complex and time‑consuming process. Existing CAD systems make it easier to design a  printed circuit Board model by providing powerful development tools. Along with the increasing complexity of modern printed  circuit boards, the requirements for development tools are also growing, making them constantly improve. Using the example  of  the  Delta  Design  system,  the  process  of  improving  the  tool  for  moving  track  segments  is  described.  The  analysis  of  the  advantages and disadvantages of the existing tool is made, and the decision on the need to develop a new algorithm is justified.  Of the two proposed variants of such an algorithm, the optimal one was chosen in terms of the quality of the result obtained and  the convenience of operation.

Some Electronics Computer Aided Design (ECAD) softwares have provided several track shapes to design a Printed Circuit Board (PCB), such as right angle, rounded and trapezoidal. However, it is quite difficult to find scientific literature that can be used as a guide which explains and compiles directly about each character of the geometry. This study aims to analyze and to observe the electrical characteristics of the geometry shape on the Printed Circuit Board (PCB) path by using the finite element method. Each PCB path shape is modeled according to its geometry and physical properties, then calculated for its electrical quantity and be observed for its performance at given current. Simulation and numerical calculations showed that the shape of trapezoidal and rounded geometry have lower resistance and planar inductance of 6.8% and 7.39% respectively than the right angle shape.

AbstractTernary solder alloys have come into wide use in chip bonding, printed circuit board connection, and in ceramic package sealing applications. Little is known concerning phase equilibria in many of these systems. Methods for predicting phase equilibria in the ternary (Pb+Sn)+Ag system using CAD (computer aided design) are described, and a predicted value for the ternary eutectic temperature is compared with values obtained by differential scanning calorimetry (DSC) for this system.

Purpose Many manufacturing sites require precision assembly. Particularly, similar to cell phones, assembly at the sub-mm scale is not easy, even for humans. In addition, the system should assemble each part with adequate force and avoid breaking the circuits with excessive force. The purpose of this study is to assemble high precision components with relatively reasonable vision devices compared to previous studies. Design/methodology/approach This paper presents a vision-force guided precise assembly system using a force sensor and two charge coupled device (CCD) cameras without an expensive 3-dimensional (3D) sensor or computer-aided design model. The system accurately estimates 6 degrees-of-freedom (DOF) poses from a 2D image in real time and assembles parts with the proper force. Findings In this experiment, three connectors are assembled on a printed circuit board. This system obtains high accuracy under 1 mm and 1 degree error, which shows that this system is effective. Originality/value This is a new method for sub-mm assembly using only two CCD cameras and one force sensor.
