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

Kester makes a thermocouple solder: Alloy SN10PB88AG2 Flux "44" Core 58 Diam 0.031" I have used this to solder thermocouples to pcbs when profiling for lead-free temperatures. When done you can unsolder the thermocouple and reuse it again. This g

I'd love to get to the point that I could discuss the impact of flux on dross formation. Until then, I fight with proper solder pot temperature, maintaining enough pump speed, and solder contaminants.

Hi...i have a question. After you solder a circuit board, what do you wash the flux residue off with? I am hesitant to use water for fear of subsequent corrosion, and have no clue as to what kind of flux is in my solder wire. automated pcb assembly

Hi Dave, Thanks for your great help! Well, gold fingers are always on any kind of cards, right? Or you were confused by my poor English...sorry!:-( Now we are going to implement some kind of method to prevent the gold fingers from being contaminated

Hey Gyver: If you don�t mind (which you don�t have any choice about, because I�m going to do it anyhow, cause it�s MY word processor), I�m going to respond genericly, but still be directed to your question. Much of the following is paraphrased from

We are mounting an microphone device (SMT package) onto a PCB - how? Surface mount line or hand soldering? Contamination can only come from the solder paste, solder wire, flux, or burning the component/PCB assembly during hand soldering. Unless the

Tnks Patrick, additional infos..... we are just playng with different NC solder wires L-F, the best results in terms of solderability (faster solder flowing, holes filling up) it seams are coming from an ROM1, as we know, according to J-STD-004, or

Thank you guys for your help, I do not clean any on my assemblies who are build by the SMT an wave soldering department, we do used liquid fluxes Kester 951 and cored wire keester 245, usually it�s for batteries connector, led, terminal and wire rap
