Group set-up for printed circuit board assembly
The current practice in the assembly of electronic components on printed circuit boards (PCBs) is serial production. a process characterized by very long set-up times. However, with the advent of efficient on-line process information .. new production control methods are now possible. This paper proposes a different production method, called the group set-up (GSU) method, which can significantl...
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...
متن کاملSurface Finishing for Printed Circuit Boards
In a world of ever-increasing electronic component complexity and pin count requirements for component packaging, focus is once again on the age-old question of "How do we preserve solderable surfaces between PWB manufacturing and assembly?" PCB manufacturers today are faced with the decision of which surface finish to offer their customers, while their customers struggle with choosing the best...
