Um, yeah, well... Me and Jeff said we'd do this surface mount solder workshop a zillion weeks ago. But, life, well, you know... Sorry I've not made it happen.<BR>
<BR>
<BR>
I was just talking to Jeff yesterday about it. Finding the time when both he and I have a spare day is the challenge. But I'd love to do it. And, I promise I will. But I can't promise a date. (At the moment I'm furiously trying to finish the hardware for the next version of TV-B-Gone, which I have to finish tonight, which is Monday morning in China, and I go traveling again in mid-April.)<BR>

<BR>
But, for the shorter term, which is, I assume, when you need to have the really tiny chip soldered, you'll need some help.<BR>
<BR>
<BR>
Unfortunately, there's a reason why that development board is so expensive: soldering chips like that is super not easy! I took a look at the datasheet on the Digikey website -- those pins are tiny! Though, for people like Jeff, who've had lots of experience with things like this -- well, he thinks it's fun. Maybe you can bribe him into showing you how sooner than we can do a full-blown workshop? But given how busy he may be, perhaps someone else out there will volunteer themselves, without being volunteered by some busy-body like me.<BR>
