Soldering makes a metal-metal connection, with the flux ensuring oxides are removed. This makes a very low resistance connection, mechanically it’s very strong, and it’s easy to automate. As a bonus it’s also very easy to undo.
Other technologies like glues and crimping have their uses but are less reliable, higher resistance, or difficult to automate.
This may change but there’s little demand. Glues have lower conductivity and are harder to remove, mechanical connectors are bulky and not as strong.
- brcmthrowaway 2y agoWhat about solder that has flux inside m?
- sitharus 2y agoIt’s the same as applying flux separately, the flux is displaced by the metal. If you’re applying fluxed solder directly there’s not much point applying separate flux to clean metal. Of course the flux will boil off pretty quickly so you need to use extra if you’re doing something where the solder wire doesn’t directly touch the components, or if the metal is old or previously soldered. The only advantage to non-fluxed solder for most hobbyists is being able to choose your flux, but for most of us rosin is fine and fairly non-toxic.
