What is an IC Substrate? IC Substrate (Integrated Circuit Substrate) is primarily used in chip packaging and serves as the “bridge” between the semiconductor chip and the printed circuit board. Chips are extremely small, with pad diameters typically around 0.05 mm, whereas the minimum pad diameter on a standard PCB is usually 0.3 mm or larger. This huge size difference makes it impossible to achie...

IC Substrate vs. Printed Circuit Board (PCB): Key Differences and Applications With the rapid advancement of semiconductor technology, electronic devices are becoming smaller, faster, and more complex. This has led to the increased demand for both IC substrates and printed circuit boards (PCBs), two essential components in electronic packaging. While they share similarities in structure and functi...
