PCB Trace Repair (Need to keep track shape?)
Since they're labeled TF, it's safe to state they're thermal fuses. 

Therefor, since inductance is likely irrelevant, you could replace them with through-hole fuses of the correct value. The current value depends on copper layer thickness, but for 1 oz. Cu, 0.4 mm would be about 1.5 A and 0.6 mm ~2.5 A... but it would be better to find out what the actual current ratings are.

N.B. Since that 0.4 mm trace is thoroughly fried, first fix the issue that burned it out. The fuse has a purpose, and it likely prevented further damage or even a fire, so don't just bypass it.
