In archiving PCB libraries, the creation and checking of the component’s parameters are very important. The checking of footprints and pin configurations from datasheets are manually done which causes delays and downtime when the components do not fit the developed PCB. It was found in a survey that 61.5% of errors come from footprints dimensions. These cause delays in the production and development of PCBs. In this study, a parameter extractor and verifier system were developed to mitigate the error of manual process of archiving library parameters from datasheets. Text recognition and pattern matching algorithms were used for the processing of images from datasheets. The 10-trial tests conducted for each footprint for the extraction of text from the cropped images for standard operating procedures (SOP) series and heat sink thin shrink small outline package (HTSSOP) series were found successful without any error. The checking of footprints and pin configuration was reduced from 45 minutes to 25 minutes. The developed system was evaluated based on user perception by 10 PCB library users which resulted to agree that the system is functional, efficient, and convenient to use.

INTRODUCTION The evolution of the design and development of printed circuit boards (PCBs) emerges with the changes in integrated circuit (IC) packages and other electronic devices [1]. The footprint and pin configuration on PCB designs from pin-holed components change as surface-mount and lightweight components evolve. Manufacturers have developed library systems for easy configuration of devices from those available locally and online. To reuse components, library systems are developed [2]. This is also applied to electronic components archiving and development of PCBs [3], [4]. The electronic circuits’ PCB design undergoes three stages namely, libraries, schematics, and board. The fundamental part in PCB design is the library. In the library can be found devices, symbols, and footprints of electronic components such as ICs [5], [6]. The components’ footprints and symbols are designed with schematics. The footprints are the arrangement of pads that are physically and electrically connected which are composed of parameters and details that help the designer to identify easily which parts need to be modified. The board plays an important role where the IC footprints [7] must be fitted well. Even in the simulation for the development of micro-electro-mechanical (MEMS), component libraries must be present [8]. The footprint components’ information must be in place even when designs vary depending on
