CC8531: Drill file for the demo design has errors?

David Tiefenbrunn
Intellectual 785 points
Part Number: CC8531

We have sent the design files to a PCB manufacturer, but they have a problem - the drill drawing seems to be showing all of the holes the same size, but there should be a few of each of 4 bigger sizes.    I can look at the files in CADSTAR, so I wrote out the list -  A = Circle 0.6/0.3  B = QFN PAD W DRILL 0.68x1.02  C = 1.8mm Not Plated Through  D = Circle 0.4/1.3  I got these numbers from the item properties menu from the holes in question.   The board manufacturer seems to be saying that the drill file doesn't have the other diameters?  I don't know, I am not familiar with the format the drill file is in.    I am not sure how to get them what they need.  The design as it is does open in CADSTAR, but a lot of things are set up drastically different than our standard way, so  I am not able to generate a new file.

I was sent here from the tech support case

    Hi David,

    Can you share which demo design you're referring to?

    Thanks,

    Alexis

    Hi,

    For Audio Jack (J1 & J2) Mounting Holes. 1.7mm - 4 Holes. Please see the following Drwg.

    For Push Button Switch ( B1) - Mounting Hole Size - 1.1mm - 2 Holes. The following is the drawing.

    All others can be the same size hole.

    Yes, this is a very old design and I couldn't find the drill drawing.  But you can use the above info.

    Thanks,

    This doesn't really help...  I can look up the parts.  I need the drill file for the PCB manufacturer fixed...  It is set up in a way that I can't do much with it, since all of the setup stuff in the CADSTAR files in this design is quite different than the setup we use.  I already sent them a list of hole sizes and the letter identifiers from the drill drawing in the design zip file, and they still couldn't build the boards.

    Hi,

    OK. If you provide the info about the Hole Sizes and Hole Identifiers then what else your PCB Fab wants?

    Thanks,

    Using the attached pdf-

    A = Circle 0.6/0.3

    B = QFN PAD W DRILL 0.68x1.02

    C = 1.8mm Not Plated Through

    D = Circle 0.4/1.3

    I got these numbers from the item properties menu from the pads / holes in question.

    Below is a pdf of the letter / hole locations.  And the 2 files that look like possibly the drill files that came with the original demo design.  Like I wrote, though, I am not sure since they are in an unfamiliar format.

    I tried to attach the files, but I'm getting an error from this website...

    Hi,

    Drill.spl and NCDrill.spl are Gerber files.

    They can open these files by using Gerber viewer.

    Thanks,

    I figured that one or the other was. 

    The  Drill.spl opens in a gerber viewer.  It shows an image of the hole positions.  It seems to have some indication on the relatively few holes that have different sizes. 

    NCDrill.spl I can only view with a text editor, it is unrecognized by the Gerber viewer I use.   It displays as a cryptic list of mostly numbers.  Nothing I can "read" to figure out if it is correct or wrong.

    The PCB manufacturer is saying that the holes are all the same size /  the data for the different diameters isn't in the file.   I have no way to check. 

    I have no way to generate a new file - Short of piece by piece re-drawing the schematic, building any part I don't have in my library, and laying out the PCB myself.  I will have to do this eventually, but we were hoping to at least get the demo design up and running before spending this time.

    NOTE - I re sent these 2 files to the PCB manufacturer.  They report that all of the hole diameters are the same size.

    I notice a flag "TI thinks this is resolved".

    It is NOT resolved.  I still do not have a usable drill file for this design.

    Hi,

    Attached are the Drill Hole Sizes.

    You can see the Drill Legend in PDF and also in Gerber Files (Drill.spl). Both are attached for your ready reference.

    We usually provide Drill Drawing ( Drill Legend with hole sizes) in PDF to PCB Fab along with Drill file and NC Drill file. This should be enough for drilling the holes on to the PCB by PCB Fab.
