[R-390] Silver solder

It did.

As you may recall, Tektronix used white ceramic terminal blocks for
component/wiring interconnect.  The solder points on those terminal blocks
included silver (and possible other metals) to create the bond to the
ceramic.  The use of "regular" solder could dilute/deplete the silver to the
point of terminal block failure.

Hi fellow solderers,

Dan has me wondering.  The most common solder sold in parts houses when I
was
buying same was 60/40 Ersin multicore which worked just fine for most all
electronic repair and construction use.  On all of our Tektronic equipment,
however, we were cautioned not to use common electronic solder but the
solder
contained on captivated little plastic spools within the equipment.  I don't
recall now what its composition was but believe it may have had silver
included.  Does anyone have a better idea about this?
