LM5146-Q1-EVM12V: LM5146-Q1-EVM12V gerber file no holes

Taras Burko

Tool/software:

Hello. I want to assemble LM5146-Q1-EVM12V, I downloaded the Gerber files for making the board. But in the production the boards come out without holes. Can you fix the Gerber files so that I can order the boards and assemble them myself?

Hello Taras,

Looks like the drill guides are included in the Gerber files, shown in the capture below. I suspect that the lack of NC drill file might be the reason for no holes since it lays out the size of the hole. I went ahead and assembled the file we typically used when requested a fabrication, see attached.

I received this response from production

"These 2 layers are drill maps , they are not drill file, could you please check with your engineer again?"

Hello Tara,

I provided NC drill files in my previous response (in zip folder), the file should provide drill instruction. Let me know if that is satisfactory for your production team.

I order PCB on the JLCPCB service. They don't support the format of your Gerber files, can you try exporting the Gerber file with different settings? You can check the archive you uploaded to the service and check if there are any holes.

Hello Taras,

Does the manufacture not accept the NC drill file provided as well? typically this is provided to the manufacture alongside the gerber files to identify the drill location and size. If not can you provide what file type is accepted.

This is what the production files look like

We will need NC drill file, not drill map or drill drawing. The NC drill file contains the shape and the location of the drill, like the below picture:
