Authentication of Printed Circuit Boards
International Symposium for Testing and Failure Analysis, 2016Abstract Printed Circuit Boards (PCBs) are easy target for reverse engineering and counterfeiting attacks due to the distributed supply chain. The integrated circuits (ICs) authentication techniques such as Physically Unclonable Function (PUF) are not easily extendible to PCBs.

Shielded Tracks on a Printed Circuit Board
Journal of Electromagnetic Waves and Applications, 2005Fully shielded tracks can be embedded in multilayer printed circuit boards by a novel manufacturing technique. The paper presents a numerical analysis of the influence of dimension tolerances on the characteristic impedance. For partly shielded tracks the coupling between tracks and the environment is studied as well.

Simulation of Printed Circuit-board Manufacturing
Journal of the Operational Research Society, 1989The paper describes a simulation model that was built to predict the production output of a printed circuit-board manufacturer. Such a prediction with traditional forecasting tools is difficult owing to varying lot sizes, designs, processing time, product mix, machining capacity and fluctuating work-force.

Slow light on a printed circuit board
Optics Letters, 2011Slow-light effects induced by stimulated Raman scattering in polymer waveguides on a printed circuit board are shown to enable a widely tunable delay of broadband optical signals, suggesting an advantageous platform for optical information processing and ultrafast optical waveform transformation.

Printed circuit board assembly
1991The ability to assemble a printed circuit board to a consistently high quality is essential to the manufacture of electronic devices. Printed circuit board assembly covers a wide range of different processes which are dependent on the types of component to be assembled, the two major types of components being leaded components and surface mount ...

Electromagnetic interference from printed circuit boards connected by flexible printed circuit board
2008 Asia-Pacific Symposium on Electromagnetic Compatibility and 19th International Zurich Symposium on Electromagnetic Compatibility, 2008Flexible printed circuit (FPC) has used for the 3D wiring in the electronic equipment. PCBs are often located in 3D and connected by FPC to make the electronic device small. In this case the PCBs are faced each other in small distance and have electromagnetic interference.

Performance requirements for electronic devices are constantly growing. The requirements put on printed circuit boards (PCBs) as a basis of these devices are growing in the same way. Without powerful EDA tools being available, the design of modern PCBs with high packing density would no longer be possible. Since each PCB must be optimally fitted to the

Printed circuit board manufacture [PDF]
, 1991 The term printed circuit board (usually abbreviated to PCB), which is synonymous with the term printed wiring board (or PWB), is used to describe a substrate which provides mechanical support and the necessary electrical connections for an electronic circuit.
