This article explores the latest advancements, practical applications, and ongoing challenges in the field of rectifier diodes, offering a valuable resource for engineers seeking to elevate their knowledge and practical skills. Diode, electronic component that conducts current in one direction Introduction Rectifier diode stands as a fundamental building block in the vast domain of electronics, enabling the conversion of alternating current (AC) to direct current (DC). This conversion powers everything from our household appliances to computing devices, ensuring their reliability and efficiency. Rectifier diodes utilize semiconductor properties to allow current to flow in only one direction, effectively filtering out any reversals typical of AC input. This directional control of electrical […]

Despite the prevalence of newer surface mount technology, THT still retains several unique benefits that underscore its enduring relevance. Find out which method is best for your projects. In electronics assembly, you’ll typically deal with two main component assembly methods: Surface-mount technology (SMT) assembly and Through-hole assembly (THT).SMT assembly is a technique where components are placed directly onto a printed circuit board (PCB). This efficient method leads to a densely packed yet lighter final product. In contrast, through-hole assembly has been around for a while. Here, components are inserted into pre-drilled holes on the PCB and then wave-soldered from the bottom to fill the holes and establish the necessary interconnections. […]

Vias go through two or more layers of PCBs to form an electrical connection. Making them right under the component’s pad saves space, reduces track inductance and simplifies design. Vertical interconnect access (or via) are small electrical connections that enable the transfer of electrical signals between different layers of a Printed Circuit Board (PCB). If we consider the tracks to be present in the x and y axes of the board, vias exist in the z-axis. Structurally, they are just like tiny coated vertical pipes plated with a layer of conductive material (such as copper/gold) and placed in a drill hole. They are also filled with different substances to ensure […]

This article delves into the technology behind Metal core PCBs (MCPCBs), recent advancements, practical engineering applications, and the challenges faced in their implementation.   Introduction The miniaturization and ever-increasing power demands of modern electronics create a significant challenge: thermal management. Traditional printed circuit boards (PCBs) often struggle to dissipate heat effectively, leading to component overheating and potential system failure. Metal core PCBs (MCPCBs) offer a revolutionary solution! Metal Core PCBs are a specialized type of PCB that integrates a core layer of high thermal conductivity metal, typically aluminum or copper. This core acts as a highly efficient heat sink, drawing heat away from heat-generating components on the board. This innovation is crucial in fields where efficient heat […]

This article explores the key factors influencing trace width, provides practical guidelines, and highlights best practices for selecting the correct dimensions based on current-carrying demands in modern PCB design. Traces on a Printed Circuit Board (PCB) Introduction PCB trace width refers to the physical width of the copper pathways on a printed circuit board that carries electrical current. It is an essential design parameter because trace width directly impacts how much current a trace can safely carry without overheating or failing. If a trace is too narrow for the current flowing through it, the higher electrical resistance of the trace will cause excessive Joule Heating (I²R losses), leading to heat buildup. This can result […]
