🔍 Key Concepts

• Flux purpose in soldering (what it does to metal surfaces) • Difference between acid flux and rosin flux and where each is used • Why electronic components and printed circuit boards need non-corrosive, non-conductive residues

💭 Think About

• Think about what would happen if leftover flux residue slowly ate away (corroded) small copper traces on a circuit board. • Consider whether the flux type should remain electrically insulating or become conductive after soldering. • Ask yourself which types of flux are commonly used in plumbing versus in electronics and why they are different.

✅ Before You Answer

• Verify which flux types are corrosive and which are not. • Check which flux residue is designed to be non-conductive after soldering electronic components. • Eliminate any flux types that are normally associated with pipes or heavy metalwork rather than delicate circuit boards.
