Title: Soldering flux
Post by: srinivas_paturi on July 24, 2017, 04:43:20 PM

Hi,

I am using lead free solder for quadcopter build. While there is no need to use soldering flux for some connections, but I think need to use flux while connecting thick wires (for ex: Battery JST connectors).

What is the soldering flux recommended here? (i.e when using lead free solder)

Thanks,
Srinivas
