Forward Transfer

Current challenges in printed circuit board (PCB) assembly require high-resolution deposition of ultra-fine pitch components (<0.3 mm and <60 μm respectively), high throughput and compatibility with flexible substrates, which are poorly met by the conventional deposition techniques (e.g., stencil printing). Laser-Induced Forward Transfer (LIFT) constitutes an excellent alternative for assembly of electronic components: it is fully compatible with lead-free soldering materials and offers high-resolution printing of solder paste bumps (<60 μm) and throughput (up to 10,000 pads/s). In this work, the laser-process conditions which allow control over the transfer of solder paste bumps and arrays, with form factors in line with the features of fine pitch PCBs, are investigated. The study of solder paste as a function of donor/receiver gap confirmed that controllable printing of bumps containing many microparticles is feasible for a gap < 100 μm from a donor layer thickness set at 100 and 150 μm. The transfer of solder bumps with resolution < 100 μm and solder micropatterns on different substrates, including PCB and silver pads, have been achieved. Finally, the successful operation of a LED interconnected to a pin connector bonded to a laser-printed solder micro-pattern was demonstrated.

The Consistent Mixed Tank Reactor is widely used in chemical processing plants, food processing industries and in pharmaceutical industries. The Consistent Mixed Tank Reactor is a nonlinear process. If any of inputs to the process or any parameters in the process gets changed means the entire working of the plant gets changed. And also it leads to decrease the accuracy of the final or end product. So, to get required end result the accuracy developed in the Consistent Mixed Tank Reactor process where the tank is in running condition need to be identified and necessary steps should be taken to avoid those fault. There are several fault diagnosis methods available. Among those techniques, the Neural System Prescient Controller can be utilized to identify and diagnose the error present inside Consistent Mixed Tank Reactor tank. From the Neural System Prescient Controller, the servo response is obtained to understand clearly about the behavior of the Consistent Mixed Tank Reactor tank process. Thus, by selecting suitable controlling techniques the accuracy of the desired product can be obtained in Consistent Mixed Tank Reactor tank.

After a review of the nature of staphylococci and staphylococcal enterotoxins including data on survival of these organisms under both natural and food processing conditions, the epidemiology of staphylococcal intoxications is discussed. The human nose is the main reservoir of Staphylococcus aureus. A number of circumstances must be fulfilled for foodborne staphylococcal intoxications to occur; these include: a reservoir for the infectious agent, a mode of dissemination of the organism, contamination of a food capable of supporting bacterial growth, enough time at a temperature which permits bacterial multiplication, and ingestion of sufficient amounts of staphylococcal enterotoxin by susceptible hosts. Control measures must be based on these circumstances. Principles of control, therefore, include limitation of contamination, inhibition of growth, and destruction of the organism. Control of staphylococcal intoxication must be emphasized at places foods are prepared (food processing plants, food-service establishments, and homes).

This second edition of the book continues the basic premise that a thorough knowledge of the mechanisms by which neurons respond to electrical stimulation, how to control the stimulation and the regional anatomy allows the Deep Brain Stimulation (DBS) programmer to effectively and efficiently help patients reach optimal control of their disorder. There are a great many variables that influence the patient’s response to DBS, such as the exact nature of the patient’s individual symptoms and disabilities and the variability of the surgical placement of stimulating leads. The complexity has expanded because rapid increases in technology, both current and anticipated. The book makes no assumptions as to the prior knowledge or expertise. As the brain fundamentally is an electrical device, the book begins explaining the relevant electronics, building a nearly intuitive knowledge of how electrons are affected by electrical and magnetic forces and how the actions of the programmer controls electrical charges that ultimately activate neurons, which themselves are electrical devices.

<p class="0abstract"><span lang="EN-US">Smart home is a residential building that is usually new or modern equipped with necessary tools and wiring that enable its occupants to control a number of electrical devices and several household appliances through a suitable software. Recently, the development of home automation systems is accelerating rapidly as a result of the rapid intersection of modern technologies. Here we are talking about systems for home communication networks as well as entertainment, security, convenience, etc. These systems are controlled by sending signals through wires distributed throughout the house or Through wireless means to programmable keys or devices so that they understand these commands and deal with them as desired. In this paper, I will discuss how to design the circuit with appropriate components, build it in Printed Circuit Board and connect it to a personal computer by using programmable language in order to control all home appliances by just one click. </span></p>

High Output

In ultrasonic systems, power amplifiers are one of the most important electronic components used to supply output voltages to ultrasonic devices. If ultrasonic devices have low sensitivity and limited maximum allowable voltages, it can be quite challenging to detect the echo signal in the ultrasonic system itself. Therefore, the class-J power amplifier, which can generate high output power with high efficiency, is proposed for such ultrasonic device applications. The class-J power amplifier developed has a power efficiency of 63.91% and a gain of 28.16 dB at 25 MHz and 13.52 dBm input. The pulse-echo measurement method was used to verify the performance of the electronic components used in the ultrasonic system. The echo signal appearing with the discharged high voltage signal was measured. The amplitude of the first echo signal in the measured echo signal spectrum was 4.4 V and the total-harmonic-distortion (THD), including the fundamental signal and the second harmonic, was 22.35%. The amplitude of the second echo signal was 1.08 V, and the THD, including the fundamental signal and the second harmonic, was 12.45%. These results confirm that a class-J power amplifier can supply a very high output echo signal to an ultrasonic device.
