LM5022: PMP9648 reference design missing drill files

Part Number: LM5022
Other Parts Discussed in Thread: PMP9648,

Hello,

I want to build the reference design PMP9648.  There are no drill files; only Gerber drill files.  I have tried 3 PCB manufacturers and none will accept these.  I have no method of converting the Gerber drill files into NC Drill files.

Please can you generate the drill files and send them to me?

Thanks,

James

    Hi James,

    Thank you for considering the LM5022 and the PMP9648. We will see if we can find out the original design files. Note that the design was created about 5 years ago, and our documentation means have changed a lot, and hopefully we can still get the original design file.

    Thanks,

    I've managed to create a drill file from the Gerbers.

    I edited PMP9648 REVB.GG1 (the drill guide) using NotePad++ to remove the border data and a Gerber viewer to check I hadn't removed the drill location cross-hairs.  Once I had a Gerber file with just the cross-hairs, I extracted the drill position.  Each cross-hair is drawn as follows:

    X0093700Y0228600D02*
    X0098700D01*
    X0096200Y0226100D02*
    Y0231100D01*

    The drill location is the Y value on the first line and the X value on the third line.  This is written to the NC Drill file as:

    X0096200Y0228600.

    Then I added the tool sizes and assigned the coordinates to the appropriate tool. It didn't take too long.

    I've attached the file in case it's useful for anyone else.
