Role of Polychlorinated Biphenyls (PCBs) and Polycyclic Aromatic Hydrocarbons (PAHs) on Survival of Free Ranging Birds: A Review
Abstract: The PCB contaminant levels reported in tissues individuals are not likely to have an impact on the demographic performance of the birds as a whole. However, the residues may reach levels causing decreased reproduction or survival in some years, particularly when combined with other non-anthropogenic stressors such as food scarcity. In addition, the birds normally would have more exposure to the contaminants due to their position in the food chain. …

Design and Development of Metallic Isolators for Wedge Lock Mounted Printed Circuit Boards (PCBs)
Abstract: Wedge lock interfaces are preferred for mounting printed circuit boards (PCBs) in electronic packages of air borne vehicles. Merits of this particular mounting configuration are high mounting stiffness, high vibration dissipation and low thermal interface resistance. However, good amount of vibration dissipation occurs only in the close vicinity of wedge locks provided integral to PCBs; because of which electronic components can be mounted only near the wedge locks on PCB. …

Introduction to Multiphysics Simulation for Integrated PCB Design and Operation AI Environment Analysis on Behalf of EMI/EMC
Abstract: Modern trend of PCB (Print Circuit Boards) designing are highly complex and unpredictable. User requirements make the PCB compact and faster nowadays. To make the PCB compact and faster in nature, multidimensional PCBs are trending nowadays. Although multidimensional PCBs are better in size and speed but also have some irrelevant issues like resonance, crosstalk, power/ground bounce and simultaneous switching noise (SSN). All irrelevant issues are responsible for EMI (Electromagnetic Interference). …

Scheduling of PCB Assembly Using Particle Swarm Optimization Algorithm
Abstract: This paper deals with the problem of scheduling ‘N’ printed circuit boards (PCBs) on a single machine equipped with an automatic component interchange mechanism. The total number of different components required to process all ‘N’ PCBs is greater than the capacity of the spool. If the essential components are not on the spool, then one or more component switches must take place earlier than the PCB can be processed. The …

Development and Experimental Characterization of Metallic Spring Isolators for Electronic Packages of Air Borne Vehicles
Abstract: During flight, electronic packages in air borne vehicles will experience aerodynamic induced loads like random vibration and shock. PCBs mounted in these packages either malfunction or fail due to high vibration which is due to the stacked mounting of PCBs. Desired gap between any two adjacent PCBs will be maintained with the help of rigid spacers in this mounting. It is understood that the solution for reducing this high vibration …

Efficient PCB Fault Detection System using Deep Learning and Image Processing
Abstract: Printed Circuit Boards (PCBs) are essential parts that support the operation of electronic equipment in a variety of sectors. Nevertheless, difficulties that manufacturers regularly face during the PCB manufacturing process lead to defective devices. However, current inspection processes occur after etching, wasting a lot of material and rendering defective PCBs unusable. This study discusses relevant practical difficulties and offers a method for identifying errors in real PCB images using Matlab …

Inverse Model for Predicting Thermal Abnormality of the Transient Process Triggered by Defective Electronics Element
Abstract: The paper presents a model for predicting thermal abnormalities in Printed Circuit Boards (PCBs) by approximating the thermal process of electric elements with heating from point sources. Circuit board heat sources are defined as point and non-point. The point heat source is a small electronic heating element that can be approximated as having originated from one point on the circuit board. A non-point source is one with heat distributed over …

Development and Characterization of Rubber Composites using E-Waste Residue as Functional Filler
Abstract: In the present study, residue generated during the recycling of end-of-life printed circuit boards (PCBs) was utilized as a functional filler in natural rubber to fabricate eco-friendly composites using mixing and molding techniques. Chemical analysis of the residue revealed the presence of several metals, including copper, iron, lead, tin, and zinc. The presence of these metals highlights the need for proper recycling and safe management of PCB residues, as their …

Design and Analysis of Substrate Integrated Waveguide for High Frequency Applications
Abstract: AbstractIn this paper, substrate integrated waveguide has been designed and analyzed for high frequency applications. As high frequency suffers attenuation due to metal waveguide, atmospheric attenuation and rain fade etc., an improved waveguide method is adapted known as Substrate Integrated Waveguide. SIW is transition between micro-strip antenna and dielectric filled waveguide antenna. SIWs are planar structures, so they can be fabricated over PCBs and can be easily integrated with supplementary …

Environmental estrogens: A silent enemy
Abstract: Throughout our lives we are exposed to environmental estrogens, from food, air, water, soil, and household products as well as probably through breast milk or during development in the womb. Environmental estrogens have endocrine disrupting activity. Many times natural plant compounds or synthetic chemicals may also disturb the endocrine system. These compounds are weaker than the estrogen naturally produced in the body. Many reproductive, developmental and other health problems have …
