[Elecraft] Leaded or non-leaded solder

[Raymond METZGER]

Hello Elecrafters,

I have decided to install KPAIO3MDKT on the K3S, I'm just starting to build,
which means soldering one electrolytic capacitor on two existing pads on the
KPAI03 module board.
I don't know it the Elecraft modules - or all PCB devices in the USA - use
leaded or non-leaded solder. Anyway, can I use my leaded solder to do this
job  ?

My soldering iron and my leaded solder haven't been used significantly since
I finished my K2-100 and my KAT100 in 2007, so that my solder has been
bought before no-leaded solder became the norm (at least) in Europe.
Thank you for your help
