Printed Circuit Boards (PCBs) form the backbone of modern electronics, and the manufacturing process involves various detailed steps to ensure precision and functionality. Central to this process is the use of Gerber files, which are the industry standard for PCB design data. These files contain critical information about the PCB's layout, including copper layers, solder masks, silkscreens, and more. This article explores the different Gerber file extensions used in PCB manufacturing and highlights how PCBGOGO, a leading PCB manufacturer, leverages these files to deliver high-quality products.

Understanding Gerber Files

Gerber files are essentially 2D binary image formats that represent various layers of a PCB. Developed by Ucamco, these files are indispensable for communicating design specifications to PCB manufacturers. Each file corresponds to a different layer or component of the PCB design, ensuring that every detail is meticulously crafted during production.

Common Gerber File Extensions

1. GBR or GER

Description: These are the most common extensions used for Gerber files. They contain information about the different layers of a PCB design, including copper traces, drill holes, and silkscreen layers.

Usage: While .GBR and .GER are widely accepted, specific extensions are often preferred for clarity.

2. PHO

Description: This extension is sometimes used for photoplotter output files, which are similar to Gerber files and contain the same type of information.

Usage: Primarily used in older systems or specific workflows involving photoplotting.

3. TOP and BOT

TOP: Used to differentiate the top layer of a PCB design.

BOT: Used to differentiate the bottom layer of a PCB design.

Usage: Helps in easily identifying and organizing files for the top and bottom layers.

4. SMT and SMB

SMT (Solder Mask Top): Indicates the solder mask top layer of a PCB design.

SMB (Solder Mask Bottom): Indicates the solder mask bottom layer of a PCB design.

Usage: These files specify areas on the PCB that need to be protected from solder.

5. CMP

Description: This extension is sometimes used for the top layer of a PCB design that shows the components.

Usage: Provides a detailed view of where components will be placed on the top layer.

6. PLC

Description: This extension is sometimes used for the top layer of a PCB design that shows the placement of components.

Usage: Crucial for assembling the PCB as it shows where each component should be placed.

7. SOL

Description: This extension is sometimes used for the bottom layer of a PCB design that shows the copper traces.

Usage: Specifies the conductive pathways on the bottom layer of the PCB.

8. STC and .STS

STC (Solder Stencil Top): Used for the top layer of a PCB design that shows the solder stencil information for stencil printing.

STS (Solder Stencil Bottom): Used for the bottom layer of a PCB design that shows the solder stencil information for stencil printing.

Usage: Essential for the stencil printing process, detailing where solder paste should be applied.

9. DRD

Description: This extension is used to indicate drill data for a PCB design that shows where the holes should be drilled into the board.

Usage: Contains information on the locations and sizes of all drilled holes, including vias and through-holes.
