Heatbed fuse circuit problems

[ohad135123]

Hi!
I hvae the pro C.
Previously, my fuse (LF15A) on the GT2560 burnt with it's holder. As a result, I couldn't get the heatbed to heat. I fixed it up by buying a few fuses online, and inserting them into the burnt holder.
Although it worked, for some reason it generated a lot of heat and burnt more fuses as a result of the resistance caused by the burnt fuse holder. So, I decided to remove the fuse holder and solder the fuse directly to the mainboard. As I removed the holder carefully, I noticed that there is no "metal sheet" I can solder the fuse to. See the pics below. What can be done so I can get the heatbed to work again?
Thanks.
