Investigation on current capabilities of Ni-based conductive pastes for PCB repair

The paper presents some electrical and thermal tests and experiments related to the current capabilities of PCB traces repaired with Nickel-based conductive paste. The lack of available scientific information in this topic motivated us to perform this investigation regarding the heating of a PCB trace segment made from conductive paste during current flowing through it. Based on the experimental results, the authors want to offer a reliable technical resource in the case of traces repaired with Ni-based conductive paste or other applications where traces made of conductive paste are used.
