Abstract
Some Electronics Computer Aided Design (ECAD) softwares have provided several track shapes to design a Printed Circuit Board (PCB), such as right angle, rounded and trapezoidal. However, it is quite difficult to find scientific literature that can be used as a guide which explains and compiles directly about each character of the geometry. This study aims to analyze and to observe the electrical characteristics of the geometry shape on the Printed Circuit Board (PCB) path by using the finite element method. Each PCB path shape is modeled according to its geometry and physical properties, then calculated for its electrical quantity and be observed for its performance at given current. Simulation and numerical calculations showed that the shape of trapezoidal and rounded geometry have lower resistance and planar inductance of 6.8% and 7.39% respectively than the right angle shape.

Summary
Papan rangkaian tercetak atau printed circuit board (PCB) adalah piranti yang esensial dan penting bagi kalangan akademik, hobbyist, profesional, dan industri besar. Proses manufakturisasi rangkaian elektronika hingga menjadi bentuk PCB diawali dari gambar skema atau diagram rangkaian, kemudian menetapkan kemasan komponen (packaging) dari setiap komponen yang ada di skema tersebut, dan kemudian melakukan penyambungan jalur (routing track). Semakin banyak komponen maka konsekuensinya semakin banyak titik (kaki komponen) yang harus disambungkan, sehingga sering terjadi bahwa jalur PCB terpaksa harus berkelok-kelok atau bahkan menggunakan via (sambungan tembus papan/layer) agar demi dapat terhubung dengan titik target [3]. Selain itu juga sangat sedikit literatur atau artikel yang menjelaskan tentang bagaimana efek bentuk geometri jalur PCB terhadap rangkaian atau potensi apa saja yang ditimbulkan oleh bentuk geometri tersebut dan bagaimana karakteristik kelistrikannya. Artikel ini bertujuan untuk memberikan penjelasan secara parametrik tentang bentuk geometri jalur PCB dengan cara memodelkan bentuk geometri dan membandingkan hasilnya. Pemodelan yang digunakan menggunakan kaidah dan pendekatan finite element analysis
