[SI-LIST] Re: Power handling

It seems OK.

BTW, SynQor (power supply mfr) wrote good paper on pin-to-plane (including
thermals) temperature behaviour.         Check it out on their site.

Subject: [SI-LIST] Power handling



This is a little off the signal integrity field, but it concerns PCB design.

Each pin of a power connector (diameter = 3.75mm) that is to be mounted on a
PCB is expected to carry a current of up to 25A of the -48V supply. I was
just wondering if  tapping off the power to three 2oz power planes would be
sufficient. I would appreciate any comments on that. My concern is the
effect of the small plane-pin contact area and the high current (8A per
contact area).

Thanks.

Hassan.
