Mounting holes on new B version

Sat Dec 22, 2012 2:43 pm

Hi,
I got my Raspbery Pi few days ago, and found very unpractical that mounting holes are prepared for M2.5 screw.

It is not any good reason for that, secure copper ring around holes is big enough to accommodate M3 screw without of any problem. With that improvement your board is usable and developer of cases will appreciate that.

Regards,
Dubravko

Apparently they're not actually mounting holes - they're used in production for alligning the boards.

That said, how much force are you intending to apply to your Pi, that a M2.5 screw would be less secure than a M3?
Also, to spread the load, why not use an M3 plastic washer?

I didnt use any force against PCB :) ... just drill 3mm holes , instead of existing holes, and still i have approximately 10-20mils board space till inner diameter of cooper ring.

CPC list 3mm as the smallest screw PCB mounting pillars, however they also stock nylon snap fit pillars that are meant for 2.5mm holes. http://cpc.farnell.com/richco/mdlsp1-04 ... dp/PC01434.
