Through-Hole Soldering

maker

A soldering technique that involves inserting component leads through pre-drilled holes on a printed circuit board (PCB) and soldering them to pads on the opposite side.

expanded

Through-hole soldering is a method used in electronics assembly where component leads are placed into drilled holes on a PCB and soldered to opposite pads. It ensures strong mechanical bonds and electrical connectivity, which is crucial in handling high-stress environments. This technique is pivotal in producing durable hardware in industries like automotive and heavy machinery.

examples

Using through-hole soldering for securing a 470 µF, 35 V radial leaded electrolytic capacitor on a double-sided PCB with a thickness of 1.6 mm.

Commonly used in power supply circuits and amplifier boards, where components are expected to withstand physical stress and vibration.

Employment of through-hole soldering for mounting 0.25 W, 5% tolerance carbon film resistors on a 2-layer PCB.

Widely implemented in educational projects, prototype designs, and repair works where manual soldering facilitates ease of rework and component replacement.
