Recycling of Printed Circuit Boards
Printed circuit boards (PCBs) can be found in any piece of electrical or electronic equipment: nearly all electronic items, including calculators and remote control units, contain large circuit boards; an increasing number of white goods, as washing machines contains circuit boards for example in electronic timers. PCBs contain metals, polymers, ceramics and are manufactured by sophisticated te...
متن کاملPyrolysis of Printed Circuit Boards
Printed Circuit Board (PCB) is an essential component of almost all electrical and electron ic equipments. The rapid growth of the use of such equipments has contributed enormously to the generation of large quantity of waste PCBs. The WPCBs not only contain valuable metals but also a large variety of hazardous materials. Conventional treatments of such WPCBs have their own limitations. By pyro...
متن کاملCrosstalk on Printed Circuit Boards
This document treats the crosstalk between parallel conductors. The conductors can represent either conductors in a multiconductor cable or traces on a printed circuit board (PCB). An analysis method based on a lumped circuit equivalent for the problem as well as a method to calculate the per unit length parameters are presented. The computed results are validated by comparison with measurement...
متن کاملEE368: Reverse Engineering of Printed Circuit Boards
For this project, a program was written which can automatically reverse-engineer a netlist of a oneor two-layer printed circuit board (PCBs) from photos of the board. Reverseengineering a printed circuit board (PCB) is useful for purposes such as repairing equipment for which component-level documentation is not available, integrating a poorly-documented board into a system, and for identifying...
متن کاملPath Optimization For Computer Numerical Control-Printed Circuit Boards In Holes Drilling Process - Case Study
Electronic manufacturing sector uses Computer Numerical Control (CNC) machines for drilling holes on Printed Circuit Board (PCB). Some machines do not choose the optimal route when completing their tasks. Hence, this paper proposes an approach, which is based on my Algorithm Shortest Path Search Algorithm (SPSA), for finding the optimal route in PCB holes drilling process. In SPSA, when the rob...
