@hexed bridge Idk how to explain it

[hexed bridge]

Take a pic or something

Take a picture of the cable and the cutout

[limber vigil]

But the soldering iron with the cable wouldn't stick to the ESC. It's on it but with a little pull the soldering iron comes off again

[hexed bridge]

What iron are you using

And how long are you keeping it held to the cable

[limber vigil]

Leaderpro and I tried everything from 350 to 400 degrees

[limber vigil]

Tried really short really long put on soldering grease that made it even worse and now it won't come off...

[hexed bridge]

What grease???

Make sure it’s not plumbing flux

Can you take a picture of your FC and cable currently?

[limber vigil]

Took the cable off

I'm really frustrated right now tbh

I mean I tried for over an hour now

[hexed bridge]

Hmm

I can help you

But you have to listen closely, alright?

[limber vigil]

Yeah

Sure

[hexed bridge]

• wipe your iron until it’s clean
• apply a bit of solder to the tip, not much.
• touch the large pad with the iron. Just one of them.
• wait about 10-30 sec, whenever you see the solder start to wet the pad.
• add a bit more solder, make sure it is wetting the pad
• add the wire. This will cool the whole thing down, so your iron needs to be on there for a while. Try to heat both the pad and the wire at the same time
• add more solder until it covers everything

[limber vigil]

Yeah that's what I tried I was watching a video of somebody soldering the same board the problem is that the pad does not really get wet with the soldering

That's why I tried that grease or what ever you call it in English

[hexed bridge]

Then either you are not using a good enough iron, using the wrong solder, or you don’t have enough flux, or all of the above
