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 کاملAnalysis of Multilayered Printed Circuit Boards using Computed Tomography
Computed Tomography is a technique that can be performed using a set of X-ray images to re-create a three dimensional dataset which contains information about internal structure. Analysis of multilayered Printed Circuit Boards with their components using this technique allows for the non destructive evaluation of internal layers of failed boards. This report presents the results of computerised...
متن کاملPower Bus Isolation Using Power Islands in Printed Circuit Boards
Power islands are often employed in printed circuit board (PCB) designs to alleviate the problem of power bus noise coupling between circuits. Good isolation can be obtained over a wide frequency band due to the large series impedance provided by the gap between the power islands. However, power bus resonances may degrade the isolation at high frequencies. The amount of isolation also depends o...
