Electronic instrumentation has a constant growth density layout and functionality. This entails an increase in the density of interconnection elements by increasing their number and reducing the size of it. The growing cost of interconnection structures (printed circuit boards, printing and wired mounting) associated with their complexity and increase of their reliability requirements, result in the search of new and improved non-destructive diagnostic methods and means of control. However, the existing methods do not allow control interconnects with sufficient certainty to identify a significant number of hidden defects. This class of defects can be diagnosed by means of non-destructive testing of interconnections, based on the detection of controlled circuit reaction to a current. The paper describes the principles for calculating the current to exercise that control.ΠΠ»Π΅ΠΊΡΡΠΎΠ½Π½ΠΎΠ΅ ΠΏΡΠΈΠ±ΠΎΡΠΎΡΡΡΠΎΠ΅Π½ΠΈΠ΅ Π½Π°Ρ

The development of printed circuit board technology is a subject to the general trend of electronics development, an increase in functionality and performance. This requires printed circuit boards to increase the assembly density of electronic components and interconnections and reduction of constructive delays in transmission lines of information. Seemingly, this will require the use of high frequency materials such as polytetrafluorethylenes (PTPE) or radiofrequency ceramics. However, this would require a multi-billion dollar restructuring of the industry of printed circuit boards. The article shows that under certain conditions it is possible to do without the restructuring of the industry, remaining on traditional foil epoxy-glass composite dielectrics. But for this purpose, it is necessary to take into account their characteristics and properties of their components.El desarrollo de la tecnologΓa de placa de circuito impreso sigue la tendencia general del desarrollo de la electrΓ³nica: se busca producir un aumento tanto en la funcionalidad como en el rendimiento. Esto requiere placas de circuito impreso para aumentar la densidad de ensamblaje de componentes electrΓ³nicos e interconexiones y reducir los retrasos constructivos en las lΓneas de transmisiΓ³n de informaciΓ³n. Aparentemente, esto requerirΓa el uso de materiales de alta frecuencia como tereftalato de polietileno o cerΓ‘mica de radiofrecuencia. Sin embargo, ello conllevarΓa una reestructuraciΓ³n multimillonaria de la industria de placas de circuito impreso. El presente artΓculo muestra que, cumpliΓ©ndose ciertas condiciones, es posible prescindir de la reestructuraciΓ³n de la industria, permaneciendo el uso de dielΓ©ctricos compuestos de lΓ‘mina de vidrio epoxi tradicionales. Sin embargo, para lograr este propΓ³sito es necesario tener en cuenta las caracterΓsticas y propiedades de sus componentes.Π Π°Π·Π²ΠΈΡΠΈΠ΅ ΡΠ΅Ρ

Development of the Digital Site for Chemical Processes in the Manufacturing of Printed Circuit Boards
The article defines digital methods for controlling the quality of chemical processes. An architecture of a digital production line, which ensures the distribution of the computational load between the system components, is proposed. We considered the process of developing a prototype of a digital production site for servicing the etching operation during which controllable process parameters are determined; both hardware and software structures of the digital site are proposed. Studying the site operability, we determined the relationships between the process parameters, which made it possible to determine the boundaries of the designed system
