Great writeup.<br>
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:<br>
<br>
<a href="http://triembed.org/images/b1.png">http://triembed.org/images/b1.png</a><br>
<br>
(the Eagle files are the same URL but ending FAT-SOIC8.{brd,sch})<br>
<br>
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.<br>
<br>
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.<br>
<br>
I notice that the N channel chip you point to can handle pulses over
100 amperes. Wow. <br>

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. <br>
