Introduction
High reliability for electronic systems/assemblies is critical for various industry sectors and their continued success. Electronic devices include Printed Circuit Board (PCB) as the key component for optimal operation/performance. Selection of the materials used in PCBs is critical to make the assemblies highly reliable and free from corrosion.

Conventional Solution
Among the primary factors affecting the reliability of electronic systems is the surface finish applied on PCB copper pads – a need commonly met by technology manufacturers through the Electroless Nickel Immersion Gold (ENIG) process.

Conventional ENIG currently available in the market is prone to black-pad defects associated with de-wetting of solder. The root cause of black-pad defects has been identified as hyper corrosion activity at Gold (Au) and Nickel-Phosphorous (Ni-P) interface ...

One of the main problems faced by alcohol industry is product dilution or alteration. Product dilution or alteration means a situation when people drink a bad alcohol drink that has been altered or diluted with different solutions after the alcohol drink has left the licensed legitimate manufacturer’s production line. The dilution process of the alcoholic beverage will be done depending up on the alcoholic beverage type and brand. The type and volume of the solution that is used to dilute the beverage also depend up on the type and brand of the alcoholic beverage. This dilution will cause big health risks and will lead to serious health issues and this will lead to mistrust on the original manufacturer of ...

Micro-mass sensors can be used for the detection of gases, organic cells, viruses and bacteria in a system. With today's growing need for immediate virus detection systems such as COVID-19, micro-mass sensors have become a viable and attractive option. As a demonstration of the capabilities of this sensor, an operational model has been developed for CO2 molecules, being the same system that could be used for other types of applications.

The microfabrication process used to the development of this systems opens new opportunities for the development of highly integrated microsensors, with lower energy consumption, foot-print, and fabrication costs than the actual technology.

The final product can be considered as a preindustrial product that with a few adaptions can be ...

LED video displays are a $15B market. It is also the last passive-matrix video device in production. The existing process uses discrete LEDs on conventional PCBs. With a passive backplane, all the image artifacts, drive issues and poor video quality that drove all other passive displays out of existence are preventing LED based displays from entering new markets such as digital cinema, and encroaching on the high-end, large TV market. No active-backplane technology has the required combination of performance, scalability and cost of manufacture.

COMPETITIVE ADVANTAGE

Silicon on Demand [1] is a novel, patented, and low-cost process for printing large numbers of small regions of single-crystal silicon on large area substrates. The process makes use of well-established semiconductor industry technologies. For ...

EXECUTIVE SUMMARY

Wireless IoT devices are notoriously easy to hack. Often an attacker goes unnoticed as they assume the identity of an edge device and use it to connect with the network. Once in a network, the hacker may cause a great deal of damage or steal important information.

Endpoint Security is completing the development of a product that will give every fixed, wireless IoT device the ability to use multi-factor authentication. We hope to use it to eliminate a particularly elusive wireless cyber-attack vector, a man-in-the-middle attack. This type of attack stems from a perpetrator spoofing a wireless edge device after eavesdropping on the communications to learn its media access control (MAC) address, encryption key and password.

The solution will use ...

Catastrophic failure concerns of Li-ion batteries including excessive heating, fires and explosions create anxiety in battery consumer markets, especially as larger and more powerful Li-ion battery architecture hits the marketplace.

The main cause of failure is the internal short-circuit, which causes thermal runaway and ignition of the battery flammable materials.

Available methods to detect expected battery failure are not precise, costly, and time-consuming requiring days, weeks or even months. Internal shorts significantly increase normal cell leakage (self-discharge) which can be used as a metric for short detection and catastrophic failure prediction.

INL’s Battery Health Sentry is a simple and accurate technique for rapidly detecting internal shorts via fast measurement of self-discharge current in lithium-ion batteries.

The method involves connecting ...

As per title the power to run the sensor can be generate using Biomass and Bacterial colony.

There are several species of bacteria that can produce Bio-gas to generate power for sensors.

To produce biogas or power, these bacterial colony will be depend on  liquid of leaves of tree, grass. The liquid can be obtained by just crushing the leaves and grass. As per sketch just  infuse the liquid gained from tree leaves or grass into the Vial filled with bacterial colony as a food for bacterial colony and the colony will work to provide power in the form of gas. This gas can be used directly to powering the sensor or as a fuel cell. I know there ...

Avalanche photodiodes (APD's) offer increased sensitivity over photodiodes. Applications such as Lidar and fiber optic communications experience significant performance improvements by taking advantage of the higher sensitivity afforded by APD's.

However, APD's require a high voltage bias of ~50V to 600V or higher. Current bias power supply options are often too bulky, heavy and expensive for practical use in high volume applications and size constrained systems such as automotive or drone Lidar imaging.

Start-up power supply company Mike Doherty Designs, LLC, a Colorado Corporation, has targeted this market and has developed a miniature, very low cost design with a suite of APD specific features otherwise unavailable in the marketplace.

Despite its small size and low cost, this line of ...

During this time one of the many efforts farmers have made to increase the production of strawberries has been with the use of inorganic fertilizer. The market demands that continue to rise in the production of strawberries make one of the factors that make inorganic fertilizers integral to our farm world. But promoting good growth requires good planting and so many nutrients in it that measuring it requires. The design measures nitrogen, potassium and phosphorus in the strawberry plants by the topology of the star grid, hardware used for soil insurgent measuring sensors, soil sensors, and NodeMCU as the microcontroller. The real-time database used on this craftsmanship is firebase. From the results of testing done to the device proves ...

Railway hawkers are people who carry snacks on trains. They carry the snacks in trays which they hold in hands. Being heavy it’s most likely that their hands will ache at some point in time and it's not even comfortable to carry the tray in a crowded train. To overcome this some of them use self-originated techniques like using a hand towel. Tying the tray with the cloth around the neck. As the problems might look small but could impact more on the human body. The weight of the tray and holding it inappropriately can lead to physical health issues body disorders and many more things. As this business is carried out in crowded trains the hawkers need to ...
