how to solder manganin 0.05mm manganin wire to a copper plate | 29 January, 2015
Nichrome, manganin, phosphor bronze etc are easy to solder ... the hard part is removing the corrosion * Manganin: 86% copper, 12% manganese, 2% nickel. Often, it's used in making cryogenic measurements, due to its low heat loss. * Select a flux for soldering stainless steel, kovar or nickel * All of the bigboy solder suppliers [eg, Superior, Indium, Alpha, etc] have products that will work * Choose a water soluble, rather than a low residue flux. Make sure you clean it well. Your flux supplier will have suggestions if you cannot use water. * If this is a cryogenic application, minimize the amount of solder on the connection to the manganin wire
how to solder manganin 0.05mm manganin wire to a copper plate | 30 January, 2015
Thanks a lot , my application is cryogenic in nature. I am trying to make a Sub-Angstrom resolution Thermal expansion sensor, whose components have been machined out of OHFC copper, and i needed to solder a manganin wire to one of the capcitor plates around 2mm in height and 7mm in diameter , but i failed again and again , this information is very vital and i would like to express my sincerest gratitude for your kind reply. I will have some more questions as i go along , and it would be very helpful if you could reply again.
