Right flux for alpaca selective soldering | 24 September, 2012

Hi,

i am using AIM 264-5 No Clean flux for soldering alpaca pieces on PCB boads, but i am having problems: poor filling and no solder.

I am using SAC 305 lead free solder.

I have tried to change flux pressure, time, ammount as well solder speed and temperature.

Suggestions???

So, I just learned that alpaca isn't just a cousin of the llama, it's also a Cu/Ni alloy (imitation silver). Creeped me out at first...

When you say "poor filling and no solder", are you referring to wetting problems? Do you have any photos you could post?
