PCBs for commercial products must pass a set of reliability tests in order to prove their capabilities, which goes well beyond the standard functional testing found in many products. Functional tests are the starting point, but reliability tests are where a design is proven for operation in its intended environment. To help designers plan a...
Learn how skip vias improve HDI PCB design by reducing via stacks, lowering manufacturing costs, and enhancing reliability. Explore best practices, DFM rules, and applications in high-density PCBs.
Fabrication capacity for high density PCBs and packaging is currently increasing, especially in North America and Europe. These platforms still use standard via styles, namely through-hole vias, blind and buried vias, and core vias in HDI PCBs. But the electronics assembly and packaging world is no stranger to innovation, and there are alternative via options...
Many times we discuss complex boards with unique features and sensitive routing on this blog. But the reality is that most PCBs that are mass manufactured have lower layer counts and less complexity. 2-layer PCBs will continue to be high-volume products, and they are almost always the starting point for a new designer learning about PCB layout. In...
Best Formats for 4-Layer PCB Stackups A well-chosen 4-layer PCB stackup is essential for achieving excellent signal integrity, controlled impedance, effective power distribution, low EMI, and reliable manufacturing — especially in high-speed digital, mixed-signal, RF, automotive, and industrial designs. Compared to 2-layer boards, a properly configured 4-layer stackup provides dedicated reference planes, shorter return paths,...
High temperature PCB design is a critical aspect of modern electronics, especially in applications involving high power, harsh environments, or continuous operation. PCBs operating at high power often generate significant heat and may experience repeated thermal cycling, making material selection essential for long-term reliability and performance. While active cooling methods such as fans or heat...
A ceramic substrate is an insulating material that provides a stable and rigid platform for mounting electronic components and creating electrical circuits. Ceramic substrates are often used as an alternative to epoxy-based materials like FR-4 (Flame Retardant 4). FR-4 is a popular substrate material for PCBs, but ceramic substrates offer certain advantages in specific applications. Key Characteristics...

PCB edge plating is a specialized process that involves applying a metal coating to the exposed copper connections at the edge of a printed circuit board (PCB). This technique, also known as side plating, battlement, or metallized edge plating, enhances electrical connectivity, structural rigidity, and electromagnetic interference (EMI) shielding. This article provides an in-depth look at the...
