Convert GKO to GBP

Understanding GKO and GBP file formats

GKO files are Gerber files used in PCB (Printed Circuit Board) design, specifically for representing outline or mechanical layers. These files are commonly generated by PCB design software and are essential for manufacturing processes.

GBP files are also Gerber files, but they specifically represent the bottom paste layer of a PCB. This layer is crucial for surface-mount technology (SMT) assembly, as it defines where solder paste should be applied on the bottom side of the board.

Why convert GKO to GBP?

Converting a GKO file to a GBP file may be necessary if you need to use the outline or mechanical layer data as a paste layer for manufacturing or assembly purposes. This is sometimes required when the original design files are missing or when repurposing mechanical data for paste application.

How to convert GKO to GBP

Since both GKO and GBP are Gerber files, the conversion process typically involves renaming the file extension and, if necessary, editing the file content to match the requirements of the paste layer. However, for accurate conversion, it is best to use PCB CAM (Computer-Aided Manufacturing) software that can import, edit, and export Gerber files.

Recommended software for GKO to GBP conversion

• GerbView: A powerful Gerber viewer and editor that allows you to open the GKO file, make necessary adjustments, and export it as a GBP file. Use File → Open to load the GKO file, then File → Save As and select the GBP extension.
• Altium Designer: Import the GKO file using File → Import, assign it to the bottom paste layer, and then export the layer as a GBP file via File → Fabrication Outputs → Gerber Files.
• KiCad: Import the GKO file into a project, assign it to the appropriate layer, and use File → Plot to generate a GBP file.

Manual conversion method

If you do not have access to specialized software, you can manually rename the file extension from .gko to .gbp. However, this method is only suitable if the file content is already compatible with the paste layer requirements. Always verify the output with a Gerber viewer before using it for manufacturing.

Summary

Converting GKO to GBP is straightforward with the right PCB CAM software. For best results, use tools like GerbView, Altium Designer, or KiCad to ensure the converted file meets manufacturing standards.
