I picket those two parts (IRF6201 and IRF9310) because they did not have exposed heat pads. I was looking for the best bang for the buck (Very Low Rds) without a thermal pad. Please let me know if you see something on the data sheet that makes it look like there is a thermal pad.</div><div><br></div><div>Shane</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jun 26, 2015 at 1:16 PM, Robert Gasiorowski <span dir="ltr"><<a href="mailto:rgresume@gmail.com" target="_blank">rgresume@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Pete, you have exposed copper with 2 signals under IC. <div>If the IC you use has a heat pad, you may have problems.</div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jun 26, 2015 at 11:37 AM, Shane Trent via TriEmbed <span dir="ltr"><<a href="mailto:triembed@triembed.org" target="_blank">triembed@triembed.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Pete,<div><br></div><div>Nice!

I put the pull-down resistor and a handful of vias into the board as
Shane recommended. The vias are tricky, as you have to name them
with the same net name as the name of the copper flow polygons, but
then if you do a "rip up" they get optimized out. <br>
<br>
I'm going to order some of these today. If OSH Park has not slowed
down I should have them in hand a few days before the next meeting.<br>
