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

We have the possibility to buy a used Zevatech FS710 pick&place machine with vision. I've read that these machines used to be very well built but I'm wondering if it's capable to place 0603 parts accurately since it lacks a laser-type alignment AFAIK
