In the rapidly evolving field of printed circuit board (PCB) manufacturing, automated optical inspection (AOI) systems play a critical role but often face challenges such as computational inefficiencies, high costs, and limited defect data. To address these issues, we propose an ensemble methodology that combines lightweight models with custom data...
The balance scheduling of Printed Circuit Board (PCB) assembly lines plays a crucial role in enhancing production efficiency. Traditional scheduling methods rely on fixed heuristic rules, which lack flexibility and adaptability to changing production demands. To address this issue, this paper proposes a PCB assembly line scheduling method based on ...
Magistrsko delo je osredotočeno na razvoj baterijsko napajanega krmilja brezkrtačnega enosmernega motorja, s poudarkom na temperaturni optimizaciji. Delovanje krmilnega vezja sloni na obstoječi programski kodi, od do sedaj razvitih krmilnih vezij pa se razlikuje v tem, da je integrirano neposredno na priključne kontakte motorja. V magistrskem delu ...
In response to the challenges of small-size defects and low recognition rates in Printed Circuit Boards (PCBs), as well as the need for lightweight detection models that can be embedded in portable devices, this paper proposes an improved defect detection method based on a lightweight shared convolutional head using YOLOv8n. Firstly, the Spatial an...

The work in this paper incorporated printed circuit board (PCB) technology into micro-direct methanol fuel cells (µDMFCs) and conjectured and verified the performance degradation factors of PCB current collectors in µDMFCs by testing different designed configuration µDMFCs. The experiment results showed that all kinds of PCB coating can benefit fro...
Substrate materials for printed circuit boards must meet ever-increasing requirements to keep up with electronics technology development. Especially in the field of high-frequency applications such as radar and cellular broadcasting, low permittivity and the dielectric loss factor are key material parameters. In this work, the dielectric properties...
Cílem této práce je navrhnout a následně zrealizovat minimálně osmikanálový radiofrekvenční (RF) generátor malých signálů pro mikrovlnnou hypertermii na frekvenci 434 MHz. Návrh bude sestaven na základě požadavků komerčně dostupného DDS (Direct Digital Synthesis) obvodu s ohledem na požadovanou výstupní frekvenci generovaného signálu. Pro návrh byl...
Tato práce se zabývá návrhem a realizací řídicí jednotky pro ovládání adresovatelných LED pásků. Nejprve byl proveden průzkum trhu s dostupnými LED pásky a analýza jejich vlastností, na základě čehož byly stanoveny základní požadavky na řídicí jednotku. Dále byl vybrán vhodný hardware a komponenty, následoval návrh elektronického schématu a desky p...
Power Electronics Converters (PEC) play a crucial role in the operation of many modern electrical systems and devices. Despite their widespread use, the lack of an efficient and cost-effective disassembly process can limit their repairability, refurbishability, remanufacturability and, ultimately, recyclability, thus hindering the circularity of pr...
