[time-nuts] 5 Mhz to 10 Mhz and 25 Mhz

Tue Sep 10 13:57:00 UTC 2019

Don, don't worry too much about soldering the 8-pin SOIC's. You've been
soldering 0.05" pitch TO-92's for decades. And each 4-pin side of a SOIC is
0.05" pitch as well.

Rather than use an adapter with perfboard, I'd advise going with dead-bug
with all grounded SOIC pins going straight to copper PCB and the other ones
flying. The flying SOIC pins you can stagger-bend to make them easier to
tack parts to.
