Printed circuit board assembly time minimisation using a novel Bees Algorithm

Integer Programming Approach to Printed Circuit Board Assembly Time Optimization

A printed circuit board (PCB) assembly task requires that a set of components be picked from their respective pickup locations and then be placed at their respective placement locations on the card being assembled. A pick-and-place robot is used for automated assembly of PCB’s. The overall assembly time depends on two different decision variables (i) the pickup locations of the components (in g...

Wavelet-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...

Printed Circuit Board Layout Time Estimation

System design complexity is growing rapidly. As a result, current development costs can be staggering and are constantly increasing. As designers produce ever larger and more complex systems, it is becoming increasingly difficult to estimate how much time it will take to design and verify these designs. To compound this problem, system design cost estimation still does not have a quantitative a...

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 ...
