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

ABSTRACT

This article describes a novel visual information concealment technique, referred to as optical watermarking, for the authentication of original printed documents. An optical watermark is a two-dimensional binary image. It can be of any shape and can be printed on any part of a document. The optical watermark is constructed by the superposition of multiple two-dimensional binary images (referred to as layers), each with different carrier structural patterns embedding various hidden information. The hidden information ....etc

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

In telecommunication, there are several types of microstrip antennas (also known as printed antennas) the most common of which is the microstrip patch antenna or patch antenna.

Microstrip Patch Antenna
Microstrip patch antennas are among the most popular antennas, used in various application areas. Model building for this type of antennas can be done in two ways: in WIPL-D general-purpose 3D modeler and in the tool specialized for printed structures, AW Modeler. A simple microstrip patch antenna is simulated here. The simulated results are ....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
