Pretty noobish at electronics here. That said...
I want to attach a very thin 1080 spring steel/music wire (30 AWG or ~0.25mm) to a pcb with a thru hole, hopefully in an automated way. The choice of spring steel is for the mechanical properties.
It seems like soldering stainless steel is doable, see the below links. I think that applies to spring steel as well.
- Stainless steel soldering
- Soldering Nichrome wire to Stainless steel and steel to PCB
Though it looks like I'd need special acid (HCl) flux for this.
A few questions:
- Does this seem doable?
- Is acid flux necessary here? If yes, can that be done in a reflow oven or would this need to be done totally by hand?
- I think I want the thru hole diameter to be as small as possible to roughly match the wire (Say 0.5mm), though I'm not super sure how small of a hole diameter I can get. Thoughts?
- Is there any good way to automate this? I don't think I could do a pick and place type approach here, but is there a machine that could apply the right flux, put the wires in place, and then put the thing in a reflow oven?
- If this is crazy and spring steel won't work, is there a better springy material?
