thermal relief orcad
Thanks
Yes i have found the Thermal relief settings, in this dialog box there are settings for
Small Thermall Releif and Large Thermal Relief. Bit lost on why there is 2 settings.
The options you are given are:
Annular Overdrill
Isolation Width
Spoke Width
Firstly iam not sure which iam working with small or large because when i was doing the copper pour and did the net attach I didn't intend the attachment to be a "thermal relief" but it seems there is an obvious connection between the two operations. I dont know if this is the case in all EDA tools.
I have tried changing some of the settings in the dialog box and the spokes did get larger but the settings have gone back to a default setting in the dialog box however the spokes have remained large, so again confusion as to the link between the dialog box and what i am seeing on the layout?
Thanks
Added after 1 hours 13 minutes:
Ok so Spoke width is definately the setting required, i increased the size again and it worked after i did a redraw/refresh, but it won't let me make the spokes smaller? This seems to be an orcad issue.
