Printed circuit board production is the area of expertise for tw-elektric, which has its headquarters in Furtwangen/Rohrbach in the Black Forest. The strengths are samples and medium-sized series. Printing technology, via fillers, heatsink pastes, cover lacquers, plugging technology, border metallization, buried vias, and blind holes are among the features of the product catalog, which includes printed circuit boards with one to 20 layers. The spectrum also includes impedance measurements, impedance experiments, chem.Sn, chem.Ni/Au, HAL, OSP, chem.Ag, plug gold, and impedance calculations.
