A new frontier in electronics manufacturing: Optimized deep learning techniques for PCB image reconstruction

Abstract

In the rapidly evolving electronics manufacturing sector, maintaining quality control and conducting failure analysis of Printed Circuit Boards (PCBs) are critical yet challenging tasks. This study presents a groundbreaking self-supervised learning framework to address existing gaps in the reconstruction of encoded or blurred Printed Circuit Board images. By leveraging a customized DeepLabV3+ architecture with depth-wise separable convolutions, our model is engineered to autonomously learn intrinsic Printed Circuit Board features, eliminating the need for manual data labeling. This not only alleviates computational burden but also ensures robust performance. Augmented by feature quantization and channel reduction techniques, our model stands out as both lightweight and resilient, making it highly adaptable for Printed Circuit board imaging. To validate the framework, a tailored dataset comprising raw and encoded Printed Circuit board images from diverse sources was assembled and further refined to match real-world industrial standards. Our model demonstrates unparalleled efficacy in Printed Circuit board image reconstruction, establishing a new benchmark for the field.
