Printed circuit boards design

The printed circuit board is one of the constructive elements of any modern electronic device. First of all it is intended for mechanical fixing and electrical connection of the components of electrical circuits of the electronic device.

Structurally, the printed circuit board is a plate made of dielectric material (in most cases, but it is also possible to use structures on an aluminum substrate to improve the heat dissipation) with electrical circuits formed on its surface and volume.

The development of printed circuit boards is a process of mechanical and electrical design. During the development of the printed circuit board, the electrical components are connected by conductive circuits, but the process of connecting the components is in fact one of the most recent stages of the board design and is usually denoted by the term PCB tracing.

Initially, it is required to conduct an analysis and the possibility of placing the components of the electrical circuit on the board surfaces in specified dimensions, which are usually determined by the design features of the entire product and in particular the product body.

At the end of the placement phase, the electrical elements are combined. In the process of connecting electrical components, it is necessary to take into account a number of parameters, such as the amperage, the impedance, the influence of neighboring electrical circuits, etc.

PCB design:

  • placement of components on the area indicated in the technical specification;
  • preparation of the PCB layout 3D model;
  • coordination of the components placement with the Customer on the 3D model;
  • carrying out of traces between elements according to the developed circuit solution;
  • modeling, the received design for compliance with the requirements of signal integrity, for compliance with the requirements for the power system, for compliance with the requirements of electromagnetic compatibility, for compliance with the requirements of temperature distribution;
  • preparation of the final PCB 3D model;
  • the coordination of the received design with the Customer on the 3D model;
  • preparation of the list of components for procurement;
  • preparation of gerber-files for production of printed circuit boards;
  • preparation of files for printed circuit board assembly works.
