esc soldering problem?

I cut the heatshrink off to see how easy it would be to solder the motors directly to the esc. But then I saw this, is this a problem? the solder is connected to the first chips pins, see?

Hi Mate I would say yes , have you got a de-solder pump to remove the over flow , looking at that I would want to check the others it may just be a one off as the iron may had jumped , dont forget most of these are done in a sweat shop the guy or gal may get paid $2 for 1000 items
 
Exactly like Neil said, desoldering pump, or perhaps solder wick. You can make your own if you don't have some with some copper wool, if you don't have that steel wool and flux works. You just stretch out a piece that is about as big around as the graphite in a pencil, and roll it a little, heat it on the solder and the solder will leave to the wick as it 'soaks' it up. Could also just use the bump method, just heat the glob and flick or bump the board in a way that it'd make the solder fall off.


Before giving the ESC power make 101% sure nothing is bridged, if something is it may cause the ESC to catch fire. Next time don't add so much solder ;)

To help avoid adding too much tin both places, and then touch the wire to the pad in the correct position (centered and not touching) then heat the two with your CLEAN and TINNED soldering tip, you want to clean the black off and then lightly tin the tip. Gives better thermal conduction.

I didnt solder this. This is how it came. Thanks for the desoldering tips thou. I was just hoping that this chip was suppost to be soldered like that..

Might be fine, but I'd contact the seller and get a refund ore replacement, then try to fix it. That is some terrible soldering, some 8 year olds aren't as good as others it seems hahahahaha
 
I just cut open the heatshrink to another esc, it is soldered and jointed ti the pins if the first chip almost identically

Would it be plausible to say, that this is okay, maybe that pad first goes to that chip?

I need to figure this out.. I got everythinf in the mail I need, my taranis plus, the voltage meter and power harness, the battery will be here today, and if everything gors smoothly.. I hope to fly tonight.. as ling as the esc aren't fd up :/

I bet each pad is just connected to all the pins on each side.
