PCB Thermal Design Guide — practical advice on component placement, thermal vias, copper pours, and thermal resistance analysis to improve reliability and performance.

Designing a PCB stackup is often considered optional because PCB manufacturers can assist with stackup creation. However, the stackup is directly related to signal integrity, EMI performance, and product reliability. This makes PCB Stackup Design an essential skill for any hardware engineer. Understanding stackup principles helps you select a structure that fits manufacturing constraints while […]

RF (Radio Frequency) circuits exhibit distributed parameter characteristics, making them sensitive to skin effects, coupling, ground noise, and layout constraints during actual operation. As a result, PCB designers often encounter EMI issues such as interference between digital and analog domains, power noise, or grounding problems. Therefore, finding the right balance between layout, routing, grounding, and shielding is crucial to achieving a stable and reliable RF design.

The Internet of Things (IoT) connects countless devices and enables seamless data communication across industries. Among all wireless technologies, Bluetooth Low Energy (BLE) has become one of the most essential due to its extremely low power consumption, mature ecosystem, and strong compatibility with smartphones.
