Through-Hole Assembly (THT) is a traditional PCB assembly method where electronic components are mounted by inserting their leads through pre-drilled holes in the PCB, and then soldered to pads on the opposite side of the board. Through-hole assembly is still widely used for components that require high mechanical strength, such as connectors, electrolytic capacitors, transformers, and other large or heavy components, as well as for prototypes and low-volume production runs.
PCBFuture provides high-quality, reliable through-hole assembly services, with both automated wave soldering and manual soldering capabilities to meet your project requirements. Our experienced soldering technicians are IPC-certified, and can handle even the most complex through-hole assembly projects with precision and consistency.
