The qualification of printed circuit boards, electronic components and auxiliary materials plays a central role in the electronics industry, where reliability and performance are crucial. These processes ensure that the materials and components used meet the highest quality standards.
Careful qualification of these elements not only ensures compliance with industry standards, but also helps to reduce waste, maximize product life and improve the overall efficiency of electronics manufacturing. Qualification thus forms the foundation for the creation of reliable and innovative electronic products.
