- Through-Hole Technology (THT) :: components are threaded through holes in a PCB and soldered from the back
- Surface Mount Device (SMD) or Surface Mount Technology (SMT) :: components are placed on the surface of a PCB and solder onto the surface
- packages :: shape, form and dimensions of components
- solder pads :: blank ( copper ) footprint on which the component is soldered to the PCB
