UB2001 gerbers wrong

[Schrikdraad]

Hello,

I'm new on this forum and hopefully you guys can help me out.

I've been working with UB2001 for a couple of years now and have sent my designs multiple times to PCB-manufacturing companies. I recently swapped to another manufacturer who has warned me several times for incorrect gerbers. Thank god they could fix the problem, but now they ask me to fix it.

The problem: I export my 2layer print to gerber 274X (copper bottom, top, board outline, soldermask top and bottom).

The drill files are exported via excellon. What happens is that my solderpads are shaped in a donut instead of solid pads. My manufacturer is not happy with this and suggests i have to change the option to create solid pads. However..i can not find this option.

When i open the gerberfile in a gerberviewer, i indeed see a lot of solderpads having a hole in it (the so called donut shape). Not all of the pads have this problem..It goes a bit random over my design.

How can i change all my pads in solid pads?

Hope somebody can help me out.

Hi,

Could you please post your files?

What gerberviewer do you use? Thre are some known problems with some gerberviewers.

Hey Bas,

Thanks for willing to have a look. I attached the gerbers as a zipfile.

I'm curious if you can see what's going wrong.

The viewer i'm using is not really a viewer, more a converter. Anyway it's gerbmagic (from bronzware).

Hello Schrikdraad,

After installing the 2001 professional version on a newer system (xp) i had the same problem.
In the gerber properties window the 'open drill holes' selection was missing.
When i looked at de files in the UB2001 dir on both systems, the difference here was the GerberExp.dll
The wrong working version had a dll dated 16-10-2002, the good working dll version (NT) was dated 18-12-2002.
After i copied the newer dll to the xp pc this version is working good.
Now i am trying to find out why there is a differance between both dll's. As far as i know was UB installed on both
computers from the same CD (SP2). Maybe there is a patch available for this problem.
I also have access to a UB power pro system with the same problem, unfortunately does the dll not work on both versions.
So, I am looking for a patch or newer GerberExp.dll for UB2001 power pro network.

Succes

Hi All,

There is an update for this issue and you should go to the support page and create a service request number, I will uplad the file for you.  Please indicate the version you are using i.e. Pro, Power Pro etc...  Since I can only upload file to a temp location and it gets remove automatically, I won't post the link here.

The link below is where you can create a service request number:

@Tien: Thanx a lot for the reply. I tried to create a 'service request number' but did not succeed. Via the link you posted i sent an email to the NI-engineers. I hope this will work and the patch or file i need will be uploaded soon.

Hi,

Can you tell me what version you have i.e.  Pro or Power Pro etc...I can need to upload the right file for you.

Hi Schrikdraad,

I think I had the same problem a few weeks ago with my PCB supplier...

I also had the donut shaped holes in my PCB...

this resulted in poor gerber quality (also 274X), they said diameters were not correct.

I believe the outer diameter of circles was larger than the inner on..

The solution was this:

While exporting to gerber, in your gerber properties window:

-Never have the "open pad holes" option on, it should NOT be marked.

-Dont mark the "board outline" mark in the same options window

This should do it...

well, at least, my problems were solved...

good luck
