soft solder

Thân thiện

A technician uses soft solder to join two electrical wires.

Definition

Noun: A type of solder, which is a fusible metal alloy, that melts at a relatively low temperature, typically below 450°C (842°F). It is used to join metal components without melting the base metals.

Usage

"Soft solder" is used to describe the specific low-melting-point material used in soldering. It is commonly composed of tin and lead, though lead-free alloys are now prevalent. This term distinguishes it from "hard solder" or "brazing alloy," which require much higher temperatures.

Examples

• Noun:
  • The electrician used soft solder to connect the copper wires.
  • For this delicate electronic repair, you will need a roll of lead-free soft solder.

Advanced Usage

• Technical Context: In metallurgy and electronics, "soft solder" specifies the joining process and material properties, emphasizing its suitability for heat-sensitive components.
  • The circuit board assembly requires a soft solder with a precise melting point.

Variants and Related Words

• Solder (n/v): The general term for the alloy or the act of joining with such an alloy.
  • He will solder the joint.
• Hard Solder (n): A solder that melts at a higher temperature, often used for stronger joints in jewelry or plumbing.
• Brazing Alloy (n): A filler metal used in brazing, which involves even higher temperatures than hard soldering.

Synonyms

• Tin-lead solder (a common, though not exclusive, type of soft solder).
• Low-temperature solder.

Related Phrases

• Soft-soldering (n): The process of joining metals using soft solder.
  • Soft-soldering is a fundamental skill in electronics assembly.
