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 reality, it has been widely understood that all high-level products that are aimed at strategic sectors such as AEROSPACE, AUTOMOTIVE and POWER ELECTRONICS, require this technology . In this regard, Eltrev has been able to take up the challenge of industry 4.0 by 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.
