Hi
it seems there is a Problem with the Pictures because I cant see them. I already tried several Browsers.
I know, this article is already 9 years old now, but is there a way to send me te Pictures or to upload them again?
Kind regards

Excellent 'work around' MasterFX and a good post showing the results.

I shall save your suggestion to post as a knowlede item for all to see. Or you could post your suggestion and images yourself?

Thanks

Hi masterFX,

I remember your original post back on the original Designpark Forum! Around 2010/2011? But couldn't find it.

Great you have reposted with extra details, this will be useful for many people from now on.

Thanks.

And this is how it looks like after manufacturing

This is how I add a slotted hole:
I created a new technology file with a "mechanical" layer in it.
In each component which needs a slotted hole (e.g. USB Connector) I added a rectange with the measurements of the slot to the "mechanical" layer which, inside the plated hole (PAD) with an oval shape. See attached Image
When I generate the manufacturing plots I name the "mechanical layer" to "GM1", and almost every manufacturer can work with it.

On my board i tried two methods of making slots.

1. Put two holes next to each other (for my purposes the slot was just 2.6mm x 1.6mm so two 1.6mm unplated holes, with smaller pads as I didn't want copper round the holes, placed 1mm apart did the job). I then added a note to the Documentation layer which I added to the drill drawing. Fortunatly my PCB supplier understood what i wanted. The problem with that is that the DRC keeps flagging the two holes too close to each other as an error. However the advantage of this approach was that at lest the slots moved with the component.

2. Add a slot cutout to the board. I drew the slot once than copied/pasted it in the locations where i needed them. This method clears the DRC errors. However this method doesn't move the slot when the component moves. To aid me i put a small dot on the silkscreen layer with a centre where the end of the slot needed to be. Then i could select the dot and read off the location which i colud then use to position the pasted slot (maually using 0.01mm grid and arrow keys.

For the 'keepout' areas i drew copper pour areas on the PCB under the component (on the required side) and set them to 'pour keepout'. I had to manually route tracks around these areas when I routed the board. Again the problem with that was that the keepout didn't move when the component moved.

On some PCB packages i've used in the pst it is possible to 'group' components and other PCB items together then when one of the items is selected the whole group is selected. You can then move all the items together. This is very useful as you can get the layout for a particular part of the circuit sorted out and then move it if you need to. I know you can select multiple items and move them all toeher BUT sometimes a circuit might have lots of components and you might forget some of them.

Hello Kevin,

[quote:2ruqefh9]I have a component that needs a slotted mounting hole do i still have to do this manually.[/quote:2ruqefh9]

My current understanding is that you do need to do this manually. My thoughts are if you draw the required slot on the PCB component silkscreen you could easily transfer the location to the board? I haven't investigated, but we would like to hear your 'work around'.

[quote:2ruqefh9]I saw earlier forum posts that slotted pads were requested a lot. I think that was when V2 was around. But they are still not there on V4!![/quote:2ruqefh9]
My 'unofficial' response (subject to being corrected) is that the library structure may not support this. DesignSpark PCB development has been well supported and is being developed continuously, but some features may take longer....

[quote:2ruqefh9]Also on the same component i need to have a 'keepout' area under the component that prevents any copper in that area. Obviously i can add this to the board manually with a flood keepout on the side the component is mounted. But i have lots of these components on a board and need to be able to switch them from one side to the other. I also need to keepout to move with the component.[/quote:2ruqefh9]
Yes, clearly related to the above, but again I do not think this is currently possible.

Has anyone else solved these issues?
What was your solution?
