Using Lead free solder.
Not sure if this should be in the 'Modern Technology' section or not.
I've just been looking through the service manual for my Marantz AV receiver and it says,
"When soldering use lead free solder, Sn-Ag-Cu."
Now is this just to comply with H & S regs or are there any technical reasons why they should not be mixed?
Thanks
John
