Ekra E5 Screenprinter

EKRA E-5 is a high-performance solution
that provides cost-effective printing solutions on a wide range of substrates,
including flexible boards, PCBs, and panels.
E 5 is a highly reliable and efficient machine that
includes a range of advanced technology and efficient parts and components.
It is capable of delivering up to a resolution of 1.5 mil/pixel
at a speed of 100mm/s, whilst accurately registering patterns
and lines down to 5 microns. EKRA E 5 is equipped with a number of features,
including the machine’s Motion Analysis System,
which assists in the determination of the optimum working parameters
to ensure repeatability and accuracy in the printed results.
Furthermore, its Smart Spot System is designed
to identify the correct printing parameters for various printing techniques.
