The THT department is certainly essential to complete the services offered to our customer. In the recent past, the market suggested a slow decline for this type of component, in favor of SMT technology. In fact, it is widely understood that all high-level products that are aimed at strategic sectors such as the AEROSPACE, AUTOMOTIVE and POWER ELECTRONICS, need this technology. In this regard, Eltrev was able to take up the industry challenge 4.0 managing to integrate special processes such as SELECTIVE WELDING AND AUTOMATIC WASHING within the THT department, thus considerably increasing the quality of the products supplied.
