THT

During THT (Through- Hole Technology) the components are placed on the PDV manually. This process is called “bestücken”. The components contain contact pins which are soldered on the bottom by means of a wave solder machine.

The THT- process

Based on the print design our specialists of the planning department make a detailed sketch of the component layout on the PCB. This detailed sketch includes corresponding colours, numbers and letters enabling our employees of the THT department to assembly the PCB's manually and with the best possible care. These PCB’s are visually checked continuously during frequent hand touch.

Wave soldering

Wave soldering is an extremely precise, mechanical soldering method which guarantees a high-quality solder joint. Wave soldering makes use of nitrogen and an automated setting and working method. A strong, reliable and clean solder joint is guaranteed. The nitrogen wave soldering system SEHO PowerWave N2 is designed for medium to large-sized production volumes and particularly puts a focus on optimizing your production quality while minimizing the manufacturing costs. Based on SEHO‘s leading nitrogen technology, demanding surface mount assemblies are as perfectly soldered as through-hole assemblies.

This is accomplished with the innovative tunnel concept, individually in speed controllable conveyor segments, the reproducible flux application, the modular preheat configuration and the up-to-date soldering area which leaves nothing to be desired.
