Soldering LED Strip

Hey all,

I am trying to solder some LED strips together. I removed the silicon with a carpenter knife and can't seem to still get a good solder (probably left over silicon still)

I read online to use sandpaper on the connectors to try and get a better surface.

Has anyone done this before?? Any recommendations on the type of sandpaper?

Thanks!!

Silicon? You mean varnish (usually green)?
Add some flux if your solder isn't of the flux core type.

What type of equipment/experience do you have for soldering?

Try very fine sandpaper (600 grit)
