Through-Hole Assembly

Through-Hole Assembly


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.

High Precision China circuit card assembly Quality Control

Achieving zero-defect production in high-reliability electronics requires more than just standard assembly; it demands a rigorous, automated validation framework. For industries such as aerospace, medical devices, and automotive systems, the cost of a single solder bridge or a missing component can be catastrophic. To address these challenges, advanced China circuit card assembly providers have shifted toward comprehensive Online AOI Automated Optical Inspection systems to replace error-prone manual checks. By integrating high-resolution optical imaging with intelligent comparison algorithms, manufacturers can now ensure 100 inspection coverage across all critical production nodes.
