More bugs

Sparkylabs

1) If I go to edit my board shape I get put into some undefined mode where I cannot edit it or get out of it. The back button will undo things I have done whilst keeping me in a greyed out - out of control mode. The only way out is to close without saving and loose any changes not saved before entering the attempt to change board outline mode. I am also still confused as to why the outline needs defining twice! because unless I put a line around the board shape the autorouter gets confused and so does the PCB manufacturer! The board shape should define the outline in the Gerber. I can send an example project in.

 

2) Via's: I want to place a series of via's on my board. This board has several layers of different nets. I want my via's to be GND nets. I am constantly asked if I want to repour my plane, if I say yes this means that the plane has to be regenerated for every via I place and will take forever. if I say make unpoured then the via defaults to another net regardless of my setting. I guess I will have unpour all of my polygons and hope for the best! but really this all needs sorting out to make it easier. We have been through this before and demonstrated that things do not behave logically.

    Another bug (in CS v1.5.2), this time in the generated output files

     

    Today it happened again, so it's not a fluke.

     

    Gerber solder mask and solder paste output files can be incomplete.

     

    I know i know is should double check my outputs files, but sometimes i overlook something.

    Today (for the second time) i got e comment from my PCB assembly house that there was a problem with placing an SMT part, as there was no cutout(s) in the soldermask and also no hole(s) is the paste screen.

     

    First i checked the gerber files i sent to the assembly house, and they were right, for 1 (unique) part there were no holes in the solder and past files for this part.

    Then i check my design, same error

    Then i checked my libary, no problem there, the solder and paste screen where there and drawn correctly

     

    Reloading the footprint in the design fixed the problem, but....

    At no point in time was an 'incomplete' footprint loaded into my design, either it did not exist yet or it was complete.

     

    The problem occurred (to me) the first time after a 'respin' of a prototype (red board), some small changes needed to be made for the production series (blue board), but not on the 'problem' part.

    How do i know this, the (red) proto boards have all the layers correct, the updated version (blue board) is 'suddenly' missing solder mask and solder paste information for 1 footprint.

     

    Images below:

    1) Problem photo sent by assembly house about PCB version 1.1

    2) My reply that the Proto (V1.0) did not have this problem

    3) Found fault in current design files (screen capture)

    4) Screencapture form footprint in library

    5) Screen capture of design files after reloading footprint

    This second time i got this picture, and again the complete version is in the library:

    imageimage

    I've used this footprint also in other designs before this one, without any problems.

     

     

    Can anybody confirm this problem, and can the guys at CS please fix this.

     

    With kind regards,

    Hi Ted,

     

    I don't own CS, so only looking at this as a 'spot the difference' challenge just out of interest.. could it be due to silkscreen do you think?

    (Agree that shouldn't cause the solder stop mask to disappear, since the mask apertures should take priority I feel). I can't recall what other Altium legacy products did, not used them in years.

    The reason I suggest silkscreen, is because it looks like between the red and blue boards, you've got silkscreen text 'U2' trampling on the pad, for the one that failed (blue board), whereas the red board doesn't have that silkscreen text over the pad.

    Similarly, for your last image, there's some dark-grey stuff that may be a silkscreen? (I can't tell, as mentioned, I don't use CS, and don't know if dark-grey represents silkscreen in the CAD system).
