I'm designing a PCB that is to carry 20 amps now and may go up to 50 amps in future designs, due to the pitch's of part pins the biggest tracks I can use are 0.15" which will carry up to 6 amps, just under a 3rd of my requirement, how much extra capacity can I get from loading the PCB tracks with 0.5mm of solder ? I guess it is down to the conductivity of lead and tin
