Discussion Overview
The discussion centers around the existence and feasibility of using "fluxless solder" for soldering wires in a UHV (Ultra High Vacuum) chamber. Participants explore various types of solder, the role of flux, and the implications of soldering in a vacuum environment.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant mentions a search for fluxless solder and references tin-gold alloys but finds limited information.
- Another participant asserts that while fluxless solder exists, successful soldering typically requires flux, citing personal experience with plumbing solder.
- A different participant suggests that cleaning the surfaces to be joined is essential, especially in a vacuum, where oxidation may not be a concern.
- It is noted that solid core solder is common and may be a viable option.
- One participant advises against using acid flux for electronics, highlighting potential risks associated with its use.
- Concerns are raised about the suitability of any solder for UHV applications due to high vapor pressures, with a recommendation for clean crimps instead.
- There is a repeated emphasis on the specific requirements for soldering in a UHV chamber, questioning the effectiveness of removing flux after soldering.
Areas of Agreement / Disagreement
Participants express differing views on the necessity and effectiveness of flux in soldering for UHV applications. Some suggest that soldering with flux is acceptable if traces are removed, while others argue that solder should not be used at all in such environments. The discussion remains unresolved regarding the best approach to soldering in UHV conditions.
Contextual Notes
Participants highlight the importance of surface cleanliness and the potential risks associated with different types of flux. There are unresolved questions about the specific requirements for soldering in a UHV chamber and the implications of using various solder types.
