Intelligent Electronic Large Size Components Through-hole Assembly
♦ What is Through-Hole Assembly?
Through-Hole Assembly is the traditional way of installing
electronic components: the component pins are inserted into the
pre-drilled holes in the PCB and then fixed by soldering to achieve
electrical connection.
♦ Features of Through-Hole Assembly?
- Component Leads: Components have long, sturdy leads that pass through holes in the
PCB.
- Soldering: Leads are soldered to conductive pads on the opposite side (wave
soldering or hand soldering).
- Mechanical Strength: Provides strong physical bonds, making it ideal for high-stress
environments.
- Reliability: Better thermal and mechanical durability than SMT in some
applications.
- Larger Components: Often used for bulky parts like connectors, transformers, and
electrolytic capacitors.
