Printed circuit board inspection
This paper provides a general overview of immediate and long-term aims of the printed circuit board inspection project of The Robotics Institute. Its purpose is to highlight some of the significant issues specific to printed circuit board inspection and to provide a discussion of our basic thesis that machine inspection should be coupled with machine diagnosis of the causes of observed printed ...
متن کاملWavelet-based printed circuit board inspection algorithm
One of the backbones in electronic manufacturing industry is the printed circuit board (PCB) manufacturing. Due to the human limited resources and speed requirements, manual inspection is ineffective to inspect every printed circuit board. Hence, this paper presents an efficient algorithm for an automated visual PCB inspection system that detects and locates any defect found on PCBs. The detect...
متن کاملWavelet - Based Printed Circuit Board Inspection System
An automated visual printed circuit board (PCB) inspection system proposed in this paper is designed specifically to detect various types of defects occurred during circuit printing process in manufactory. Two-dimensional HAAR wavelet transform is incorporated in the PCB inspection algorithm of the inspection system. During the inspection, two type of images are required; reference and tested P...

Several stages of tests are performed in circuit board assembly, and each test consists of one or more noisy measurements. We consider the problem of jointly optimizing the allocation of inspection and the testing policy: that is, at which stages should a board be inspected, and at these stages, whether to accept or reject a board based on noisy test measurements. The objective is to minimize t...
متن کاملComputer Vision System for Printed Circuit Board Inspection
In this paper we present a Computer Vision system for printed circuit board (PCB) automated inspection. In the last years PCB industry has been invested in manufacturing automation improvement. This is known, especially in measurement and inspection field. We can note that the tolerances on PCB assembly become more accurate. With computer hardware and cameras advances, new Computer Vision algor...
