Introduction to PCB Surface Finishes Printed Circuit Boards (PCBs) are the backbone of modern electronics, connecting and supporting various components to create functional devices. One crucial aspect of PCB Manufacturing is the surface finish, which protects the exposed copper traces and pads from oxidation and enhances the board’s solderability. With […]

Why Transition from Gerber to IPC-2581 for PCB Data Transfer? For decades, Gerber files have been the de facto standard for transferring PCB design data from CAD to manufacturing. However, Gerber has limitations: Gerber represents layers individually without describing how they relate to each other It lacks a standardized way […]

Introduction to PCBs and Their Significance Printed Circuit Boards, commonly known as PCBs, have revolutionized the electronics industry since their inception. These small, green boards are the backbone of almost every electronic device we use today, from smartphones and computers to medical equipment and aerospace technology. PCBs have enabled the […]

What is a Varistor? A varistor, also known as a voltage-dependent resistor (VDR), is an electronic component with a non-linear resistance that varies with the applied voltage. Its primary function is to protect electronic circuits from excessive voltage spikes by diverting the surge current away from sensitive components. Varistors are […]
