PCB Single Point Ground: Design, Process, and Quality Notes Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article…

PCB Earth Plane Design: A Practical Manufacturing Guide Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB earth plane design gives you a practical advantage when…

Dielectric Withstanding Voltage Testing for PCB Insulation Withstanding voltage testing answers a simple question that no continuity test can: does the insulation between two conductors survive the voltage the product will actually see. The test applies a defined high voltage for a defined time and watches for breakdown or excess…

PCB Via Stub Length: Design and Assembly Considerations Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB via stub length gives you a practical advantage when…

Reflow Soldering Quality: Profile, Defects and Control Reflow soldering quality is decided long before the board enters the oven. The paste volume, the placement accuracy and the thermal profile together determine whether every joint forms correctly, and no amount of inspection can repair a process that was outside its window…

RF Connector Surface Treatment: Keeping The Cavity Clean Surface treatment on a connector body is usually chosen for appearance or for grip, and both are legitimate reasons to texture a metal shell. What is not legitimate is allowing that treatment to reach the inside of the connector, because the cavity…

High Speed Routing Rules for PCB Layout The rules that govern high speed routing are widely published, and most of them are accurate. The difficulty is that they are not all equally important, and a designer who tries to satisfy every one of them produces a board that is expensive,…

PCB Stub Resonance: What Matters on the Production Line Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB stub resonance gives you a practical advantage when…

Raising Efficiency in High Speed PCB Design Workflows High speed design has a reputation for being slow. Reviews take weeks, simulations consume days, and every change of a stack-up or a package forces the layout to be restarted. Some of that is inherent: signal integrity work rewards care, and a…

Conductive Anodic Filament Failure in PCB Laminate Conductive anodic filament failure is one of the few PCB defects that grows after the board has been built. Copper migrates along the interface between glass fibres and resin, slowly building a conductive path between two biased conductors. The result is a drop…
