[TriEmbed] Recommended SMD Logic-Level MOSFETs for prototyping

[Pete Soper]

Great writeup.
I found myself searching for "beefy breakouts" for SOIC-8 packages and 
couldn't find one. I just knocked this out in Eagle and would like 
comments or criticism:

(the Eagle files are the same URL but ending FAT-SOIC8.{brd,sch})

This is a dead-simple board except there are redundant traces on the 
bottom to vias that are in turn connected to the chip pads. So there are 
two .024" traces for each pin. The vias have relatively large holes I 
guestimate to have a circumference three times the trace width.

The biggest question is whether this is redundant. If there's an 
unburdened Eagle file out there that I could upload to OSHPark I might 
be able to get some boards made in time for the next meeting. This board 
would cost 47 cents. But the boards I've found so far online have 
laughably narrow traces for multiple amps.

I notice that the N channel chip you point to can handle pulses over 100 
amperes. Wow.

PS Is just crazy some times. A fraction of the time it flagged net 
connections when I added wires from the via chip pads or else refused to 
acknowledge the connection. So I'm only 92% sure there would be copper 
in some cases and the first version of this board might really only have 
single traces for some of the pins.
