normally the STM32 can handle quite a bit of heat in my experience.<br>
is the MCU already flashed in those kits or do you have to upload
the firmware first?<br>
my guess is the 2nd.<br>

I found my solder wick and was terribly happy to get all the
excess blobs off the chips. The controls and jacks went in with
ease. And then I plugged it in, fed it power (Red stripe where
it is meant to be), and nothing happened. No lights. No sound.
Nothing. I have a feeling that I severely overheated at least
the microcontroller if not a few other bits of it.<br>
<br>
That was a very expensive lesson....</div>

<p> I understand your frustration, I've been there :)</p>
<p> Best way to get rid of solder bridges on SMT chips is
to use the following;</p>
<p>1) Solder flux</p>
<p>2) Solder wick</p>
<p>3) patience</p>
<p>4) practice</p>
<p><br>
</p>
<p>you can buy numbers 1 and 2, simply cover the offending
pins in flux (I use a syringe) and then use solder wick
to lift the bridges</p>
<p>number 3 comes with time</p>
<p>number 4 you can do by grabbing an old PCB and bridging
it then practicing removing the bridges.</p>

<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>
