Thick film substrates
Metallux microelectronics is produced by means of thick film technology. Conductive tracks, resistors, and insulating dielectrics are screen printed and mounted in clean ISO 8 environment and then fired directly to the substrate. Our flexible manufacturing is all about meeting customer needs, a large variety of materials, such as: Ceramic Alumina, Aluminium Nitride (AlN) or stainless steel and flexible PCB, allow the manufacturing of your designed project up to the highest quality standards.
Expertise and services
Metallux's Mendrisio site is specialized in the production of complex substrates in thick film technology and in the assembly of microelectronics on ceramics or PCBs. High quality electronics has been produced for decades, serving the automotive, industrial, and medical industries. The site's range of services include development, support, technological product design, prototype construction, series production, and qualification procedures.

Quality assurance stations for functional tests in series production are developed and set up from in-house engineering. Our approach ensures that even the most stringent quality requirements are met. The production site has 1,300 m² of clean rooms up to ISO class 7 (class 10000). Various encapsulation processes up to hermetic enclosures complete the capabilities of the production site.
