[sdiy] Need help with a SMD kit (OT?)

[David G Dixon]

Well, the key is WHY it is frustrating.  First of all, I have dropsy -- I
drop every component at least once, it seems, on my lap or on the floor.
Drop a TH part, no big deal.  Drop an SMD part, and it winks out of
existence in this part of the universe and ends up in Captain Janeway's
minestrone.  Second of all, I don't see all that well close up anymore.
Third, I have never ever made what looked like a decent looking solder joint
on an SMD part.  My TH joints look like perfect little shiny volcanoes.
Fourth, I have a system for TH work which makes it go extremely quickly.
 
The bottom line is that I can spend more time trying to install a single SMD
resistor on a board than it takes me to stuff the whole board with TH
resistors.  And when I'm done, the TH resistors will look perfect and the
SMD resistor will be at an ugly 30-degree angle to its pads with solder all
over it.
 
SMD was developed for robots.  I don't feel a need to hone a skill to
compete with a robot, thanks.

It's only frustrating until you get some good at it. then it can be quite
rewarding to do something that you initially thought was impossible. That's
pretty much the definition of learning any new skill, isn't it?

This post sums up why I simply will not do SMD by hand.  Not... worth...
the... frustration.

Hey list, 

I bought the Elements diy kit from Synthcube and managed to get all the
surface mount components attached using solder paste, a tiny syringe, and a
hot plate. Everything melted nicely and I only burnt the solder mask a bit
because I wasn't quick enough getting it off the hot plate, but the copper
traces appear to be still attached to the board so I'm not too worried.

And then the problems started. I let the board cool down and then started
going about eliminating solder bridges on a couple of the ICs. I cleaned up
one side of the microcontroller and then made the other three worse. I got
one chip that was a little crooked seated properly and then another popped
free and I couldn't get it resoldered. 

I've stepped away from the kit so I don't do more damage or throw it against
the wall in frustration.

Is there anyone experienced in surface mount soldering (preferably in the
US) that would be willing to fix this mess for me. I'm way out of my depth
and am willing to pay postage both ways and a fee for your time.

Thanks in advance.
