Magnetic Coil PCB versus Inductor PCB: Key Differences Once a coil or an inductor is built into a board rather than wound as a separate component, two different things are being described. A magnetic coil PCB forms an electromagnetic structure that couples to another coil or to a magnetic field,…

Flexible and Rigid PCB: Where the Difference Actually Matters Ask ten engineers to describe the difference between a flexible circuit board and a rigid one and most will say flexibility, then stop. That answer hides the parts that actually change a design review. A flexible board is not a rigid…

PCB Overvoltage Crowbar: What Buyers and Engineers Should Check Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB overvoltage crowbar from the perspective of a PCBA factory floor,…

PCB Inrush Current Limiter: Taming the First Moment 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 inrush current limiter gives you a practical advantage when…

PCB Lightning Surge Test: A Practical Manufacturing Guide Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB lightning surge test from the perspective of a PCBA factory floor,…

PCB ESD Diode Placement: A Practical Manufacturing Guide 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 explains…

PCB Surge Protection Layout: A Practical Manufacturing Guide 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 explains…

Carbon Ink and Carbon Film PCB: Which to Specify Carbon on a printed circuit board does two jobs that copper cannot do cheaply. It provides a wear resistant surface for a membrane switch or a keypad contact, and it forms a resistor of a defined value without adding a component.…

PTFE PCB and Ceramic PCB: Choosing by Dk, Loss and Heat Two substrate families dominate the top of the circuit board market, and they are chosen for different reasons. A PTFE board is chosen for its electrical behaviour: a low dielectric constant, a very low loss and a stable response…

How Via Plugging and Tenting Differ: Materials and Defects Vias are plugged for two reasons that rarely appear together in the same documentation: to keep solder and flux out of an open barrel during assembly, and to create a flat surface on which a component can be placed. The first…
