padstack thermal relief
From **broken link removed**..
"Thermal Relief – The Power Plane Thermal Relief has five attributes. Thermal Relief’s have an outside diameter, an inside diameter, a spoke width, a spoke rotation and 2 or 4 spokes. The Outside Diameter is typically the same size as the Anti-pad. The inside diameter is typically 80% less than the outside diameter. The spoke width is typically 4 times smaller than the outside diameter with 4 spokes or 3 times smaller than the outside diameter with 2 spokes. The spoke rotation is normally 45 degrees with 4 spokes. All Thermal Relief feature sizes are in increments of 0.05mm."
What are the standards for five spokes thermal relief? Are there any sources for designing thermal pads? Please help. Thanks
