[Noisebridge-discuss] surface mounting a really tiny chip, anyone able to help?

[Mitch Altman]

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.

 

 

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.)

 

 

But, for the shorter term, which is, I assume, when you need to have the really tiny chip soldered, you'll need some help.

 

 

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.

 

 

Mitch.
