Maintenance — Type 561 A
Be sure to observe the soldering precautions described
in the following paragraph when soldering connections to
the new strip.
Soldering Precautions
In the production of Tektronix instruments a special
silver-bearing solder is used to establish a bond to the
ceramic terminal strips. This bond can be broken by e-
peated use of ordinary tin-lead solder or by applying too
much heat. For this reason, we recommend the use of solder
containing about 3% silver and a wedge-shaped soldering-
iron tip for installing or removing connections from the
strips. The silver-bearing solder is locally available in most
areas, or it may be purchased directly from Tektronix in
one-pound rolls (order by part number 251-514). Occasional
use of ordinary solder will not break the bond unless too
much heat is applied.
