Goedemorgen Kas, Maarten en andere lezers,

Deze site gaat over de keramische draadsteunen van Tektronics:
https://vintagetek.org/ceramic-strips/

Een vrij lang verhaal, maar het rolletje speciaal soldeer komt er ook in voor:

"Special silver-bearing solder is used to solder wires and components directly to the
notches in ceramic strips and has a composition of 60% tin, 37% lead, 3% silver. This silver-bearing solder should be used when soldering or repairing ceramic strips which prevents the silver bonded to the ceramic from dissolving in the molten solder. Failure to use the correct silver-bearing solder on Tektronix ceramic strips can result in failure of the silver to ceramic bond. Tektronix would include a small spool of silver-bearing solder for repair in some of its instruments. After assembly an air blast of ground walnut shells would clean ceramic strips of excess flux."

Het is beslist de moeite waard het hele verhaal te lezen.

Veel succes met de reparatie.
Gerrit Jan
