Most electronic hobbyist did not know how to make printed circuit board for their small circuits. In this article I will tell you how to make a printed circuit board easily. For making printed circuit board (PCB) for small circuits you need clad board, ferric chloride (FeCl2), OHP marker pen, ect.
First of all prepare the layout of the circuit using any PCB schematic drawing software (e.g. - Dip Trace, Express PCB, Eagle, PSpice, ect). Print the layout on an ordinary paper.
After preparing the layout, cut the clad board ....etc

e cash payment system ppt slides free download

Abstract
Electronic payment systems come in many forms including digital checks, debit cards, credit cards, and stored value cards. The usual security features for such systems are privacy (protection from eavesdropping), authenticity (provides user identification and message integrity), and no repudiation (prevention of later denying having performed a transaction) .

The type of electronic payment system focused on in this paper is electronic cash . As the name implies, electronic cash is an att ....etc

Innovative Printed Circuit Board Technology for Heat Removal with
Application to Power LED based Operating Room Lamps
Abstract:
Using a simple analytical model we investigate the effect of thermal vias on the heat
transfer through a printed circuit board (PCB) . We show that thermal vias can increase the heat
transfer coefficient by orders ofmagnitude. The model considers the arrangement and the geometry of
the vias, the metallization thickness and the solder fillets. The application part ofthe paper addresses
three protot ....etc
