PCB gerber file

PCB gerber file

The Gerber file format (RS274X) is the industry standard for PCB fabrication, detailing all board layers including copper, solder mask, and legend. When uploading your designs to our platform, Gerber files can be submitted in either .rar or .zip archives for seamless processing.

Board Outline file (.GKO)

Board Outline file (.GKO)

File essential for routing the board edge, as it defines the PCB's outline, including any inner slots or cut-outs. This file must contain only outline data, with no additional information included, ensuring precise cutting during fabrication.

Drill files

Drill files

These should be provided in Excellon format. Non-Plated Through Holes (NPTH) can be specified either within the board outline file or in a separate drill file labeled with 'NPTH' in the filename.

PCB File Extensions and Layers

In PCB design, specific file extensions are crucial for accurate fabrication. The Top Copper Layer (GTL) and Bottom Copper Layer (GBL) define the circuitry, while the Top (GTS) and Bottom Solder Mask (GBS) files specify solder mask application areas. The Top (GTO) and Bottom Silk Screen (GBO) files provide markings for component placement. The Board Outline file (GKO) defines the PCB's shape, and the Drills file (DRD) details hole locations for component mounting, ensuring precise manufacturing and functionality.
