Through-Hole Technology
THT Component Assembly
The process of a printed circuit board going through through-hole technology component assembly and testing.
Component Assembly
The electronic components are inserted into pre-drilled holes on the PCB by hand.
Hand Soldering
Using a heated soldering iron to melt a metal alloy and create a permanent electrical and mechanical connection on the PCB.
Wave Soldering
A machine that creates an upwelling wave that fills the through-holes and covers component leads on the PCB.
Selective Soldering
A machine that uses a small solder nozzle/fountain to apply molten solder to the designated joints on the PCB.
X-Ray Inspection
Quality control step to examine hidden internal structures, components, and solder joints. Specifically, solder voids, through-hole barrel fill, and multilayer alignment.
