Pin 1 has a little notch on it.

Hello agan, today I am at the jaguar.

And while doing Jaguar 0.4-alpha over voltage clamp trace routing mistake it ended up in this: It was actually done well when with the heat the small things to the right started de soldering, I tried to solder it back, but with the heat the small ones around started desoldering too, them the wires, over and over fuck.
Also some ping of U13 came of without me noticing. You can see here my despair and lack of experience by adding more solder to things.
What should I do ? Resolder once more ? Or move everything to a protoboard on the side.
What tool do you guys use to hold those tiny things ?? I have a small plyer but here would be needed 3 hands

Please evaluatue my other solder jobs, I added the heat shrink tube to places that might touch unwanted stuff if the wire move.

The wires here should should the middle thing of the MCs right ?

They are fugly, but I tested them for connectivity, and they are in there.
Is acetone a good way to clean the board ?

The MAP sensor came in decent.
I don't know what is up with this, some solder just go like cheese others don't really want to solder, it just stays on a puddle forever.

Clean your board with IPA before and after doing any soldering. Dust, residues, and oils from your fingers can affect the process. Directly adding flux can help with wetting and pooling; don't be afraid to soak up any excess solder with desoldering braid.

Is this the right place for the surge absorver?

The the power goes directly to there ?

The the power goes directly to there ? Where is says 12V-SW and the Sensor-GND next to it ?

The main things with the point-to-point wires is to ensure they're the right size so you don't have to trim any copper to get them through the holes. What you need to avoid is the wire being soldered to more than its own pad.

Beware soldering/desoldering a lot. I see one photo with regulator, and another without later. Eventually the copper pads will peel off of the board and you'll be screwed.

What type of solder and what type of soldering iron and tip are you using? This is important.

Voltage clamp circuit is not too important, you can ignore it and be careful with your wiring.

MAP sensor fixes should use small wire. Good quality wire is important for jumpers. Cheap wire: the insulation melts and you can't deal with it at all. I use insulated "flex" for some connections, but other shorter ones, I use cut off leads from thicker-legged components, copper only. Through away diode leads; they're steel.
