Thanks David ! Yep, those are large 47000uF electrolytics. But they will be mounted on the chassis and the board comes on top so there wont be that much physical constraints on the PCB. I have checked on some sites and metallization is coming as a chemical process after drilling the board. Thus some margin should be taken as a 5mm hole will become 4.9 after metallization (unless you specify your holes diameters are meant AFTER metallization, but 5.1mm would not be standard meaning $$$)
About the libs, I will work on a complete lib for the parts I have selected. Longer but safer :) Thanks, M. --- In [email protected], "David" <da...@...> wrote: > > > > --- In [email protected], "marcmendezbermond" <marcmendez@> wrote: > > > > Hi all ! > > > > I am looking for some footprint libs for large screw-terminal electrolytic > > capacitors.
