Is there any way on Easy-PC to select the pads that thermals will be allocated when pouring copper?

In the pad properties there is an option 'Plane Connection', you can set it to Thermal Pad (the default), Isolate from Plane and Not Isolated.

I have done a quick test and there is no difference. I have a through hole connector with only one pin connected to GND. I want to create a solid connection on the pin (no thermal pad) and leave the rest of the design with thermal pads. I tried the 3 options on the Plane Connection pane and I could not see any difference

Did you unpour and repour the copper after changing the setting?

Yes, I did. I cleared the copper and poured it back again. EZPC will add thermal regardless of the option chosen on the Plane Connection Pane. Basically, it seems that option does nothing

Iain, I think that the Developers are now all off on a deserved holiday before they hibernate again.

Found the solution ......

For this to work you MUST pour the copper with the thermal box ticked. If you don't it always simply connects the pad to the plane.

When I pour the copper I click on the box Thermal on Pads. That's what I have been doing. Iain, is that the box that you meant when you said thermal box? I am using Easy-PC v.15.0.7

Ah ..... this only works for copper pour in V16. The feature does not apply to V15 ....

Hi,

You do have a choice of applying a work arround to V15 or upgrade to V16 depending upon which would be most benifit to you !.

for V15 & older you can use work arrounds discussed in PCB topic 530 Feature Request - Exemption from thermal relief !. There you can either use pad exception to oversize the effected pads when copper has been poured but needs reset when new copper pour is done or place a small bit of copper pour arround the desired pads with thermal relief turned off then pour main copper with normal settings.

Hope that is helpful.
