Q: What is Gerber File PCB Format
A: A Gerber file, often called a Gerber RS-274X file, is a standard format used in the printed circuit board (PCB) manufacturing industry. It contains information about a PCB design’s various layers and components in a format that PCB fabrication machines and software can understand.
A PCB design typically comprises multiple layers, such as signal traces, solder masks, silkscreen, etc. Each of these layers is represented in a Gerber file. The Gerber format specifies the coordinates, shapes, sizes, and other attributes of the elements on each layer, allowing PCB manufacturers to reproduce the design on the physical circuit board accurately.
PCB design software tools generate Gerber files and are a crucial part of the manufacturing process. They provide manufacturers with the necessary information to create the physical PCB using etching, solder masking, drilling, and component placement.
In addition to the main Gerber files for each layer, additional files, such as drill files, specify the locations and sizes of holes that must be drilled into the PCB. These files collectively ensure that the manufacturer can accurately produce the designed circuit board according to the original specifications.
