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...

Title of Document: EVALUATION AND MODELING OF ELECTROCHEMICAL MIGRATION ON PRINTED CIRCUIT BOARDS Xiaofei He, PhD, 2014 Directed by: George Dieter Chair Professor Michael G. Pecht, Assistant Research Scientist Michael H. Azarian, Department of Mechanical Engineering Electrochemical migration (ECM) is the growth of conductive metal filaments on a printed circuit board (PCB) through an electrolyt...
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 کاملModeling Printed Circuit Boards with Embedded Decoupling Capacitance
Embedded capacitance is an alternative to discrete decoupling capacitors and is achieved by enhancing the natural capacitance between power and ground planes. New materials have recently been developed by competing companies that promise to reduce the cost and improve the performance of boards with embedded capacitance. This paper introduces simple models for embedded capacitance boards and exa...
