Metals Content in Printed Circuit Board Waste
This paper an presents analysis of metals in waste of printed circuit boards (PCB) covering types of PCB, segregated from PC computers, mobile phones, and mixed. The presented data identifies metals and other substances found in PCB waste based on elemental and technical analysis of PCBs. PCB categorization based on gold concentration is presented, resulting in two groups: electric and electron...
متن کاملMass analysis of the components separated from printed circuit boards
Methods of effective and ecological recycling of printed circuit boards (PCBs) are searched all over the world at this time. The material composition and temperature properties of PCB are necessary to be known for an optimal recycling technology. For this purpose we analyzed weight ratio of the electronic components moulded on the selected kinds of PCBs and next we formulated mathematic model o...
متن کاملRecycling 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...
