PCB process mechanization: various ways to automate

Purpose The purpose of this paper is to present an updated overview of printed circuit manufacturing equipment from the perspective of “mechanization strategies and systems” in order to enable printed circuit board (PCB) manufacturers to select the appropriate equipment. Design/methodology/approach Ten process mechanization strategies were studied and illustrated with emphasis on the new conveyorized vertical plating and traditional horizontal conveyors, with some highlights of reel‐to‐reel chip on flex conveyorized plating equipment. Findings Novel mechanization continues to be created to enhance the technology, quality, and productivity of printed circuit manufacturing. Research limitations/implications Mechanized equipment has the most controlled conditions for research and another publication referenced will supply information on sensors and controllers for modern high‐speed PCB processes. Originality/value The paper describes various mechanization strategies for equipment used in printed circuit manufacturing, combined with process sensors, automatic control, statistical design of experiments, and automation strategies that will present the best scenario for optimal PCB production.
