A New Line Balancing Method Considering Robot Count and Operational Costs in Electronics Assembly

Technical Library | 2019-05-02 13:47:39.0

Automating electronics assembly is complex because many devices are not manufactured on a scale that justifies the cost of setting up robotic systems, which need frequent readjustments as models change. Moreover, robots are only appropriate for a limited part of assembly because small, intricate devices are particularly difficult for them to assemble. Therefore, assembly line designers must minimize operational and readjustment costs by determining the optimal assignment of tasks and resources for workstations. Several research studies address task assignment issues, most of them dealing with robot costs as fixed amount, ignoring operational costs. In real factories, the cost of human resources is constant, whereas robot costs increase with uptime. Thus, human workload must be as large and robot workload as small as possible for the given number of humans and robots. We propose a new task assignment method that establishes a workload balancing that meet precedence and further constraints.

Flexible Bioelectronics For Physiological Signals Sensing And Disease Treatment

Technical Library | 2020-04-22 23:50:30.0

Flexible bioelectronics, including wearable and implantable electronics, have revolutionized the way of human-machine interaction due to the fact that they can provide natural and seamless interactions with humans and keep stable and durable at strained states. As sensor elements or biomimetic actuators, flexible bioelectronics can dynamically sense and monitor physiological signals, reveal real-time physical health information and provide timely precise stimulations or treatments. Thus, the flexible bioelectronics are playing increasingly important roles in human-health monitoring and disease treatment, which will significantly change the future of healthcare as well as our relationships with electronics. This review summarizes recent major progress in the development of flexible substrates or encapsulation materials, sensors, circuits and energy-autonomous powers toward digital healthcare monitoring, emphasizing its role in biomedical applications in vivo and problems in practical applications. A future perspective into the challenges and opportunities in emerging flexible bioelectronics designs for the next-generation healthcare monitoring systems is also presented.

A Printed Circuit Board Inspection System With Defect Classification Capability

Technical Library | 2013-08-15 13:12:11.0

An automated visual PCB inspection is an approach used to counter difficulties occurred in human’s manual inspection that can eliminates subjective aspects and then provides fast, quantitative, and dimensional assessments. In this study, referential approach has been implemented on template and defective PCB images to detect numerous defects on bare PCBs before etching process, since etching usually contributes most destructive defects found on PCBs. The PCB inspection system is then improved by incorporating a geometrical image registration, minimum thresholding technique and median filtering in order to solve alignment and uneven illumination problem. Finally, defect classification operation is employed in order to identify the source for six types of defects namely, missing hole, pin hole, underetch, short-circuit, mousebite, and open-circuit.

Printed Circuit Board Tracking with RFID: Speed, Efficiency and Productivity Made Simple.

Technical Library | 2008-05-07 17:54:58.0

Tracking goods through manufacturing was originally accomplished with pencil, paper and human input. Barcodes introduced an automated, machine-readable tracking mechanism that streamlined all types of manufacturing. But modern printed circuit board (PCB) assemblies are running into limitations because of barcode labels. And though barcodes and RFID tags will co-exist, the relatively large barcode labels have to find increasingly scarce real estate on high density boards.

When the Soldering Specialist Bans Soldering Fume

Technical Library | 2019-05-24 07:26:39.0

Soldering system vendor SEHO runs a Technology Center in its headquarters in Germany, in which all available machines are exhibited and demonstrated. Additionally, the SEHO Academy provides knowledge as a perfect balance of theory and practical application. In both facilities soldering fume occurs, which has damaging effects on human health, manufacturing equipment and products. That's why the company had installed several air cleaning solutions in terms of fume extraction technology. How and why they take care of clean air is the subject of this article.

An Electrochemical Sensor for Determination of Sulfite (SO32-) in Water Based on Molybdenum Disulfide Flakes/Nafion Modified Electrode

Technical Library | 2022-01-19 18:15:45.0

The assay for monitoring the content of sulfite ions (SO32−) is essentially important because sulfite has some seriously toxic effects on both environment and human health. For this, a SO32- electrochemical sensor was fabricated utilizing molybdenum disulfide (MoS2) and Nafion. The cyclic voltammetry (CV) and differential pulse voltammetry (DPV) showed that MoS2 had excellently catalytical activity for the redox of SO32-.

Soft Material-Enabled, Flexible Hybrid Electronics for Medicine, Healthcare, and Human-Machine Interfaces

Technical Library | 2020-04-08 22:57:04.0

Flexible hybrid electronics (FHE), designed in wearable and implantable configurations, have enormous applications in advanced healthcare, rapid disease diagnostics, and persistent human-machine interfaces. Soft, contoured geometries and time-dynamic deformation of the targeted tissues require high flexibility and stretchability of the integrated bioelectronics. Recent progress in developing and engineering soft materials has provided a unique opportunity to design various types of mechanically compliant and deformable systems. Here, we summarize the required properties of soft materials and their characteristics for configuring sensing and substrate components in wearable and implantable devices and systems. Details of functionality and sensitivity of the recently developed FHE are discussed with the application areas in medicine, healthcare, and machine interactions. This review concludes with a discussion on limitations of current materials, key requirements for next generation materials, and new application areas.
