Introduction to Etching Issues in Multilayer PCB Manufacturing Multilayer printed circuit boards (PCBs) are essential components in modern electronics, enabling complex circuitry to be densely packed into compact devices. The manufacturing process for multilayer PCBs involves many precise steps, one of the most critical being etching. Etching is used to […]

What is PCB etching? PCB etching is the process of removing unwanted copper from a printed circuit board (PCB) to create the desired electrical connections. The process involves applying a resist layer to the copper surface of the PCB, exposing it to light through a photomask, and then chemically etching […]

What are Gerber Files? Before diving into panelization, let’s first understand what gerber files are. Gerber files are the industry standard format for describing the layout of a printed circuit board (PCB). They contain all the necessary information for PCB fabrication, including copper layers, solder mask, silkscreen, and drill data. […]

What is a Gerber File? Before we dive into the specifics of editing a new PCB using a Gerber file as a background, let’s first understand what a Gerber file is. A Gerber file is a standard file format used in the PCB industry to describe the layout of a […]

Understanding PCB units: mm and mil Before diving into unit conversion, let’s first understand the two primary units used in PCB design: Millimeters (mm): The metric unit of length, where 1 mm equals 0.001 meters or approximately 0.0394 inches. Mils: A unit of length equal to one-thousandth of an inch, […]

Introduction to Schematic Symbols and CSV Files Schematic symbols are graphical representations of electrical or electronic components used in circuit diagrams. They provide a standardized way to represent various elements such as resistors, capacitors, transistors, and integrated circuits. Creating schematic symbols can be a time-consuming task, especially when dealing with […]

What is PCB Warpage? PCB warpage is the deviation of a PCB from its intended flat shape. It occurs when the board experiences uneven stress or thermal expansion, causing it to bend or twist. The warpage can be classified into two types: Convex Warpage: The PCB bends outward, forming a […]
