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 ....etc

Low-resistance printed conductors crucial for the development of ultra-low cost electronic systems such as radio frequency identification tags. Low resistance conductors are required to enable the fabrication of high-Q inductors, capacitors, tuned circuits, and interconnect. Furthermore, conductors of appropriate work function are also required to enable fabrication of printed Schottky diodes, necessary for rectification in RFID circuits. Last year, we demonstrated the formation of low-resistance conductive printed structures using gold nano pa ....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 proto ....etc

The inkjet printing has grown into a mature noncontact patterning method in the recent times. With this method, large-area patterns can be easily created with high speeds while using only small amounts of functional materials and also high resolution can be achieved. RFID tags, organic thin-film transistors OTFTs and electrochromic devices ECDs are the major areas employing the method of inkjet printing. The future of plastic electronics is focussed on this technology.
solution processable materials are used to print conductive features onto ....etc

PRINTED CIRCUIT BOARDS
PCB contains printed circuit of electronic equipment on it. As per circuit, the designer designs or assembles the components and parts for electronic equipment. This helps the designing easy for the designer.
Design of PCB is considered as the last step in electronic circuit design as well as the first major step in production of PCB’s.
STEPS TO DESIGN PCB S:-
1. Design and test the prototype circuit— by hand.
2. Capture the circuit’s schematic— using OrCAD Capture or simil ....etc

Abstract
This letter presents a new approach for the design ofa multiresonant printed bowtie antenna. Several techniques wereattempted to obtain one antenna which is operational in the 2, 3,and 5 GHz bands corresponding to many wireless applications.The idea of creating different slot configurations on different partsof a single antenna is the basic principle. A prototype of the finalantenna design was fabricated tested and a good agreement wasfound between simulated and tested results.
Index Terms—Bowtie antennas, circular slots, h ....etc
