This edition provides recommendations and advice on creating libraries of elements, drawing electrical circuits and designing printed circuit boards by means of P-CAD 200 and ACCEL EDA . Particular attention is paid to the systems of designation of metallized holes, contact sites and seats of various elements, standard component modules and standard formats that meet the requirements of GOST .. A special section is devoted to the design and technological parameters of printed circuit boards and surface mounting. As examples, the domestic element base was used, and the creation and release of design documentation was carried out taking into account the requirements of the ESCD. In addition, the publication contains reference material on components needed by professionals working with any means of designing REA. The book is aimed at developers of radio electronic devices of varying degrees of complexity, PCB designers, students of technical universities and radio amateurs .
