Hi,
I am going to use a heat sink with a clips on my BGA and I need to prevent other parts to come closer than a specified distance. I have placed a rectangle on "Package Keepout/Top" so other parts can't come into this region. However, I have a problem, that is the BGA itself is in this region and DRC generates error. How I can exclude this part from this rule/constraint? Is there another way that I can place a guard around my BGA?
Comments are welcome.
