Good morning all,
I have a switch on a pcb which has a button cap placed on it. I created a round keepout to avoid placing components around the switch which will hit the button cap. I draw the actuator as a second placebound top for when I view the board in 3D. Since the actuator for the switch is higher than the keepout for the button cap I get a DRC error. Is it possible to layer the keepouts so I can place a higher keepout or "keepout void" within the button cap keepout or is the only way is to change the height of the switch actuator placebound top?
You can add Min/Max Height to the second placebound so it vaults over the first placebound.
The second placebound will have a Min Height set to the Max Height of the first placebound so they never come in contact with each other in the Z-Axis and you won't get a DRC.
Hope this helpsMike Catrambone
The switch actuator goes from 185 to 390. (in mils) The first keepout is min 260, max 300, diameter 500(rim on the button). The second keepout is min 300, max 500, diameter 250(button height). I get 2 DRC errors...one constraint 260, actual 390, and the second constraint 300, actual 390. Any suggestions?
You could reduce the placebound height of the switch actuator so it goes from 185 to 260 instead of 185 to 390.
The only other option is to create openings in the other two placebounds for "rim of the button" and the "button height" so the switch actuator passes thru them without contacting them. Of course this becomes more difficult because you cannot have voids in placebound shapes so I normally goes with the first option to save the extra work.
Hope this helps,Mike Catrambone
Thank you both for your answers. I will problably just make a complex keepout.
