Abstract
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.
Highlights
Most of the operations in the technological processes in the production of printed circuit boards (PCB) are chemical, which increases their impact on the reliability of the manufactured product [1]
The primary goal of this article is to try to combine the fundamental technologies of chemical processes to manufacture PCB with digital production
Based on the presented analysis, we chose the prognosis and health management (PHM) approach to create the digital production site. We made this choice because PHM makes it possible to analyze the state of the process in real-time, obtain information about the process, and select the best operating mode for the equipment
Summary
Most of the operations in the technological processes in the production of printed circuit boards (PCB) are chemical, which increases their impact on the reliability of the manufactured product [1]. The control of these operations is difficult due to many parameters, the analysis of which can only be performed under laboratory conditions. According to a previously drawn up schedule, maintenance of such processes mainly adheres to a preventive approach, consisting of timely replacement of chemical solutions. Possible incomplete use of materials, which entails increased costs for materials and their disposal
