Laptop Motherboard Traces : Laptop motherboard traces are the copper ribbons in laptop motherboards that carry current from one component to another. When laptop components such as power jacks, short out or suffer damage, quite often the copper traces melt. Repairing the copper traces on a laptop motherboard is extremely difficult but it can be accomplished by experienced technicians.

Multi Layered Laptop Motherboards : Many laptop motherboards have copper traces sandwiched between layers of motherboard material. Repairing "hidden" traces is far more difficult, but it is also possible if a laptop technician knows what they are doing.
