Soldering Problems

[Don0407]

So I've grown use to soldering Xbox controllers for friends to replace analogs that have issues or remove rumble motors/replace them but recently i was working on my own controller when i notice the solder wouldn't stick to the analog modules legs ( talking about the silver lines that stick out into the motherboard of the controller ) and i've been trying to get the soldering to stick but to no avail and I don't know whether i damaged my board or not. I tried multiple analog modules and i'm trying to use flux by putting it on a cotton swab and just rubbing it onto the point i solder. I'll leave images of the board at the moment with no module on it. Also the little silver squares i have no idea if it's ok if they come off or not but im assuming that's what is causing them not to stick

Sorry never read the post fully - Try using some Flux.

did you recently start using a different type of solder?

Was your soldering iron hot enough? Because I somehow doubt that... Maybe try a different soldering iron?

Looks to me like you're trying to mix lead-free with leaded solder without wicking it up first. What I'd do is use a solder wick or desoldering pump to remove the solder you've got on there already (mixing the two is useful for this), then when clean go over the area with flux and try again. The board looks pretty toasty, but that's just the solder mask. The traces should still be OK.

Should i put it directly on the module???

Because i've tried to add some flux on the board maybe I didn't put it on properly

Try to tin those contacts before you solder anything to them. It looks like the contacts might have come off ant there is no metal actually there for the solder stick to?

The 3 boxes i highlighted have no contact points some of the other don't either but those specific spots just don't wanna hold a thing also do you like put it on the actual module's tip

I'm actually about to start working on it again just to recap i should tin the contact points on the module and add flux to my board ( Controller contact points completely missing )
