Right now I have an issue. I am using TPE Teflon insulated high strand count (19x34) silver plated wire for a robot project of mine.
The issue I have is it tends to just break off a lot easier at the through hole solder joint compared to your typical 7x30 stranding pvc jacket.
I am using a lead free Kester solder with silver.
Is there a better lead free alternative for high strand wire?
I have seen for example automotive boards use press fit connectors. However a connector is not an option in this case. Is it possible to press fit just a single solid wire? Then the only issue I have is reduced flexibility.
What about something like spot welding? I know sometimes the lead free solder likes to wick up the high strand count silver wire which might be why it breaks easier? Maybe spot welding by applying only a small area with heat could help this?
Any help would be appreciated.
