Technology: We meet
the highest standards
A wide range of machinery, systematic development of technology and the many years of experience and know-how of the team have focused on the production of double-sided and single-sided circuit boards on FR-4 and MC PCB and CEM-3T laminates (used in the lighting industry). The knowledge of our engineers allows us to optimize production costs while maintaining high quality.
We produce 2000 m² printed circuit boards per month.
