Curious minds: what's the best way to field heat-bond a needle onto a soldering iron?
I'm guessing mechanically secure it with something heat tolerant (steel wire) for most of the tip length + lube the interface with molten solder? Then crank it to 11 to get enough heat to the tip?
- rbanffy 2y agoMaybe drilling a hole slightly smaller than the needle and cooling down the needle until it would fit inside the hole? Or spin the needle inside the hole until it welds itself.
- lb1lf 2y agoYou make the length of the business end of the needle protruding from the tip of the iron as short as possible, wrap copper braid around tip+neddle, put on a very small hose clamp on top, then turn on the iron and give the copper braid as much solder as it can absorb. Then you start soldering, after a few successful ops you figure this is going to be a walk in the park - and are promptly attitude readjusted by a blob of solder dripping off the iron and onto your PCB. Did succeed in the end, though.
