Through-hole
Through-hole is a traditional method of assembling electronic components onto circuit boards. Think of it like putting pegs through holes in a pegboard - electronic parts have metal pins that go through pre-drilled holes in the board and are soldered on the other side. While newer methods like surface mount technology exist, through-hole assembly is still widely used for components that need extra physical strength or stability, like large connectors or parts in devices that experience a lot of movement or vibration. It's a fundamental skill in electronics manufacturing, especially for industrial and high-reliability products.
