[Elecraft] K3S solder type?

[Jerry Moore]

Anyone know the type of solder used in the K3S board manufacture? I've been
reading up on environmentally safer solder and all of the reliability issues
that result from the solder spidering over time. Anyone happen to know? 

I'm sure it's not an issue but it came to mind. I tried to call Elecraft to
ask but they are busy helping customers who need actual help with their
units J
