The standard PCB hole for 0.025 inch square pin is typically a 0.035 inch diameter.
The Amphenol FCI is not square pin, but flat tab, and can move off center inside the hole 5 or 10 thousandths (0.1 to 0.25mm) and still stay flat on the PCB, without any forcing. Which is enough to clear the CPU BGA package. I have a Mikro Ethernet click board that plugs in fine, without any apparent issues. Since we are talking about the connector sliding to the side 0.1 to 0.25mm, I think there is enough tolerance in the male pin locations and flex in the male pins to deal with this without issues. If Robert likes this solution, maybe he can get Digikey to stock the 36 position connector. --- Graham == On Friday, October 6, 2017 at 11:32:09 AM UTC-5, Giulio Moro wrote: > > Ok thanks. > By the sound of it, it seems that you would be able to fit the sockets but > then you would have to struggle to fit anything on it which is aligned to a > 0.254mm grid.
