The applications have, in turn, motivated a progression from traditional helical to recent miniaturized printed circuit board implementation, in order to improve the overall power density.

The combination of microwave-induced pyrolysis and mechanical processing is a promising way to recycle the waste printed circuit boards (WPCBs). In pyrolysis, WPCBs yield an average of 78.6 wt.% solid ...

The via-plate capacitance for a via transition to a multilayer printed circuit board is evaluated analytically in terms of higher order parallel-plate modes. The Green's function in a bounded coaxial ...

MATERIALS AND METHODS Printed circuit boards used in this research were collected by a waste electronics recycling center in the city of São Paulo - Brazil. Initially the manual dismantling of the ...
