Through-hole PCB assembly involves surface mounting electronic components onto a PCB through holes drilled in the board. Through-hole mounting facilitates the connection of component leads to conductive pads located on both sides of the drilled hole.
This form of connection is frequently employed for larger components needing greater support compared to surface-mount counterparts. Through-hole PCB assembly demands meticulous accuracy and precision due to its intricate nature.
Through-hole PCB assembly is effective for accommodating large components requiring high power and voltage.
In contrast to SMT components, through-hole components are recognized for their resilience against mechanical and environmental stress.
Through-hole technology has persevered and remains pertinent for larger and heavier components necessitating robust connections.
