Double-sided Printed Circuit Boards

From the start of our career as printed circuit board manufacturers we have focused on the manufacture of small-medium series of all kinds of metallic double-sided circuit boards, and we have a monthly manufacturing capacity of 5000 m2. Automated lines and machinery with state-of-the-art technology, complemented with auxiliary installations, guarantee a quality product and strict deadlines.

Thanks to the constant updating of our machinery and the latest advances in drilling, direct and electrolytic metallisation using pulse current, image, milling, scoring, electric testing and metallic finishes, we guarantee the efficacy and reliability of our products.
