<p>Interesting debate,</p>
<p>My tuppence if I may.</p>
<p>Soldering a 16 pin SOIC of TQFP is far quicker than a through hole 16 pin DIL. Unsoldering either can be a nightmare if the board has large power/ground planes</p>
<p>For prototyping I'm happy to do boards with around 200 parts, but for more than 3 or 4 boards I would always outsource. I have the same problem with through hole, its BORING doing the same board 10 times (I did this with the monowave, 30 of them with 1500 solder joints on each, never again!</p>
<p>I personally love the challenge of making boards small, in my current work project I've taken a board that was 100mm by 80mm, shrunk it to 63mm by 26mm, and now shrunk it to 30 x 14mm, I'm using QFNs and 0402s (with the odd 0603 that I couldn't get in 0402) and a couple of 0201's to try (just 0ohm jumpers). I've also reduced part count and cost significantly in the process. It's really not hard, but and I'll say it again, for more than 4 or so, I'd outsource it (same would be true if I did a through hole board).</p>
<p>I think a lot depends on your intended market and purpose, for work, it needs to be small, as small as small can be, if not smaller. But if you're making things for home and you're happy with through hole, stick with it :)</p>
<p>What I also like about the SMD world is the diversity of parts :)</p>
<p>Just my tuppence worth</p>

That's pretty much the definition of learning any new skill, isn't it?

<div dir="ltr">Hey list,
<div> </div>
<div>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.</div>
<div> </div>
<div>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. </div>
<div> </div>
<div>I've stepped away from the kit so I don't do more damage or throw it against the wall in frustration.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>Thanks in advance.</div>
