AIVON delivers precision-engineered 4 layer PCBs with optimized stackup design, excellent signal integrity, and superior reliability, ideal for high-speed, compact, and multi-functional electronic applications.
A 4 layer PCB consists of four conductive copper layers laminated together, typically arranged as Signal Layer / Ground Plane / Power Plane / Signal Layer. This multilayer structure offers improved electrical performance, reduced electromagnetic interference (EMI), and enhanced routing density compared to 2-layer boards. It’s widely used in complex electronic systems where stable power distribution, signal integrity, and compact design are essential. AIVON’s 4 layer PCBs are engineered with precise stackup design and impedance control to ensure reliability in high-speed and high-frequency applications.
AIVON's 4-layer stackup separates signal and power layers, minimizing crosstalk and EMI. This ensures stable signal transmission for high-speed circuits and digital communication devices.
Compared with 2-layer PCBs, AIVON's 4-layer boards allow higher routing density and smaller form factors, making them ideal for space-constrained electronics.
Each layer stackup is carefully engineered and simulated to maintain ±10% impedance tolerance for consistent high-frequency performance.
Dedicated power and ground layers improve current return paths, reduce voltage drops, and enhance overall circuit performance, essential for complex and dense designs.
