Through-hole technology

Through-hole technology or THT is a method of mounting electronic components onto the printed circuit board through inserting leads on the components into holes in the circuit board and soldering the components to the board. THT components attached in this way are usually larger than SMT components, such as capacitors or coils.

knowledge

sector-specific

Through-hole technology is an essential knowledge of the following occupations:

Printed circuit board assembler: Printed circuit board assemblers read blueprints and drawings to assemble printed circuit boards. They use hand- and automated soldering tools and machines to connect electronic components to the board.

Through-hole technology is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Printed circuit board test technician: Printed circuit board test technicians inspect and test printed circuit boards. They perform a range of printed circuit board testing procedures and may perform minor repairs.
Wave soldering machine operator: Wave soldering machine operators set up and operate machines to solder electronic components to the printed circuit board. They read blueprints and layout designs.
Automated optical inspection operator: Automated optical inspection operators (AOI operators) operate automated optical inspection machines to inspect assembled printed circuit boards. They read blueprints and inspect the finished or in-process PCB assemblies for flaws or defects.
