What is a PCB? PCB stands for “printed circuit board.” It is the base board that provides electrical connections and mechanical support for electronic components. A PCB starts as a non-conductive substrate, typically made of fiberglass (FR4), with a thin layer of copper foil laminated to one or both sides. The copper is etched away…

PCB Substrate Materials The base material of a PCB, known as the substrate, is a thin board made of insulating materials. The substrate provides mechanical support for the copper conductors and serves as the dielectric for the circuit board. Common substrate materials include: FR-4 FR-4 (Flame Retardant 4) is the most widely used PCB substrate…

What is PCB Testing? PCB testing is the process of verifying the functionality, quality, and reliability of a printed circuit board. It involves various techniques to ensure that the PCB is free from defects, such as short circuits, open circuits, incorrect component placement, and manufacturing flaws. PCB testing is essential to maintain the quality of…

How PCB Transformers Work PCB transformers operate on the principle of electromagnetic induction. They consist of two or more coils of wire, typically referred to as the primary and secondary windings, which are wound around a common magnetic core. When an alternating current (AC) is applied to the primary winding, it creates a magnetic field…
