Abstract

Saat ini PCB multi-layer banyak digunakan pada rangkaian elektronik karena mampu menyediakan PCB dengan kepadatan komponen yang lebih tinggi, kecepatan tinggi dan ukuran PCB yang relatif lebih kecil dibandingkan dengan PCB single layer. Untuk menjawab kebutuhan pasar, TFME (Teaching Factory Manucacturing of Electronics) yang merupakan salah satu laboratorium di lembaga Politeknik Batam, dirasa perlu melakukan penelitian untuk mengukur kemampuan produksi di bidang manufaktur PCB multi-layer, khususnya empat layer. Total PCB empat layer yang dibuat adalah sejumlah sembilan belas unit. Adapun metoda yang digunakan untuk mengukur kemampuan TFME dalam membuat PCB empat layer adalah dengan cara mengukur kesesuaian koneksi jalur tembaga terhadap desain dan pengecekan visual kesejajaran antar layer menggunakan mesin x-ray. Dari hasil pengujian dapat diketahui bahwa untuk PCB yang menggunakan via ukuran 0.7mm tidak memiliki cacat jalur putus.

Abstract

Robust and precise finger gesture recognition using surface electromyography (sEMG) is essential for developing intuitive prosthetic control systems. However, sEMG signals are inherently stochastic and non-stationary, posing significant challenges for high-accuracy classification in fine-grained movements. This study proposes an optimized 1D convolutional neural network (1D-CNN) framework for classifying 20 distinct fine-grained finger gestures using raw sEMG data from an 8-channel wearable Myo Armband sensor. Unlike traditional methods that rely on manual feature engineering, the proposed 1D-CNN performs end-to-end learning to automatically extract temporal features. The research specifically investigates the impact of temporal windowing strategies, ranging from 400 to 750 ms, on model performance. Experimental results demonstrate that the optimized 1D-CNN achieves a peak test accuracy of 94.4% with a 550 ms window size, demonstrating the model’s robustness across complex gesture classes and significantly outperforming the baseline principal component analysis- support vector machine (PCA-SVM) method which only attained 73.0% accuracy. While the model achieved perfect classification (100%) for index, middle, and little finger movements, a performance drop was observed in thumb recognition (50%) due to muscular crosstalk from deeper anatomical layers. These findings indicate that the integration of optimized windowing and 1D-CNN architectures provides a highly reliable solution for complex large-scale gesture recognition, offering a robust foundation for the next generation of multi-functional prosthetic hands.
