RF Via Transitions in High-Speed Designs

RF Via Transitions in High-Speed Designs: Best Practices and Considerations

In high-speed and RF PCB designs, controlling trace impedance is critical, but the role of RF via transitions is often underestimated. Vias, which connect signals between layers, can introduce impedance mismatches, signal reflections, and losses, especially at high frequencies. Proper design and optimization of via transitions are essential to maintain signal integrity and ensure reliable performance in RF and high-speed digital applications

Copper Current Density in PCB Design

According to Joule or Ohmic heating principles (represented as VI or I²R), any conductive material generates heat, leading to a gradual temperature rise in both the conductor and its surroundings. Managing copper current density is critical to ensure reliable PCB performance and prevent overheating. This article explores key considerations, design guidelines, and tools like OrCAD X to optimize copper current density in PCB designs.

Multilayer PCBs

Multilayer PCB Manufacturing Process, Advantages and Applications

A Multilayer PCB (Printed Circuit Board) is a type of PCB with more than two conductive layers. Unlike a double-sided PCB, which has two copper layers (top and bottom), a multilayer PCB consists of three or more layers of copper, interconnected by copper-plated vias. The number of layers can range from 3 layers to 40 layers or more, depending on the design requirements

PCB Substrate Materials: Understanding the Types of PCB Materials

PCB (Printed Circuit Board) substrate materials are the backbone of a PCB assembly, providing the necessary foundation for copper tracks and electronic components. The choice of PCB material plays a critical role in determining the performance, durability, and overall reliability of the PCB. These materials can be resin-based, fiberglass-based, epoxy-glass, metal-based, or flame-retardant, and they are selected based on the specific requirements of the PCB design and its application.
