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 کاملPrinted Circuit Board Deconstruction Techniques
The primary purpose of printed circuit board (PCB) reverse engineering is to determine electronic system or subsystem functionality by analyzing how components are interconnected. We performed a series of experiments using both inexpensive home-based solutions and state-of-the-art technologies with a goal of removing exterior coatings and accessing individual PCB layers. This paper presents our...
متن کاملCurrent Estimation on Multi-Layer Printed Circuit Board with Lumped Circuits by Near-Field Measurement
Current distribution on a 2-layer PCB with lumped circuits is estimated by measuring the near electric field. In this method, the current estimation model is made without considering the electrical parameters of lumped circuits. Experimental results are demonstrated and compared with the numerical results, confirming the validity of this method. key words: measurement, current distribution, nea...
متن کاملSolving The Printed Circuit Board Drilling Problem By Ant Colony Optimization Algorithm
Printed Circuit Board (PCB) manufacturing depends on the holes drilling time, which is a function of the number of holes and the order in which they are drilled. A typical PCB may have hundreds of holes and optimizing the time to complete the drilling plays a role in the production rate. At an early stage of the manufacturing process, a numerically controlled drill has to move its bit over the ...
متن کاملData mining of printed-circuit board defects
This paper discusses an industrial case study in which data mining has been applied to solve a quality engineering problem in electronics assembly. During the assembly process, solder balls occur underneath some components of printed circuit boards. The goal is to identify the cause of solder defects in a circuit board using a data mining approach. Statistical process control and design of expe...
