🔍 Key Concepts

• Printed circuit board (PCB) repair standards and what types of conductors are allowed to remain as permanent repairs • The typical uses of solder wick (desoldering braid) versus structural or electrical conductors on a PCB • Risks of using flexible braided wire as part of the circuit path on a rigid PCB (movement, shorts, overheating)

💭 Think About

• Think about the normal, approved purpose of tightly knit metal braid in electronics work: is it usually used to carry current long-term, or mainly used during the soldering/desoldering process? • For each choice, ask yourself: does this describe a temporary tool used during a repair operation or a permanent modification to the circuit? • Consider which options would increase the risk of damage to PCB traces, pads, or components if the braid stayed in place permanently.

✅ Before You Answer

• Identify which options describe braid being used temporarily during the soldering process versus left in the circuit as part of the wiring. • Check your basic electronics knowledge: what is the standard tool used to remove excess molten solder from a joint? • Before choosing, ask: would this use of braid be allowed by typical electronics maintenance/USCG or Navy technical manuals, or would it violate good PCB repair practice?
