MIVA imagers offer a wide range of imaging resolutions (from 3 000 dpi to 128 000 dpi) Each single machine has three internally switchable resolutions. MIVA imagers at the high end of the resolution spectrum are logically slower than low resolution machines but offer customers the capability of imaging very fine lines and structures. The quality of the smallest structure size offered by any imager is determined firstly by the size and continuity of the minimum projected spot size and the accuracy of the imager mechanics which position the spot incrementally while exposing the film.
MIVA imagers have one of the smallest spot sizes available on the market (minimum is 0.8 microns) and can therefore construct very fine lines of high quality and with high continuity.
The positioning accuracy of all MIVA imagers is controlled dynamically during plotting by 1,0 micron or 0.1micron resolution linear positioning encoders which operate in a closed-loop system ensuring correct pattern positioning over the whole plot area. If necessary, plot data can be pre-stretched or pre-contracted in 1,0 micron increments in each axis within the plotter before exposure. For customers working in unstable temperature environments, a temperature compensation function with an in-built sensor improves dimensional stability at higher or lower temperatures.
Stability of structure sizes is inherent in the projector system and is governed by the fixed-size DMD or LCD matrix in the projector head and the highly stable light source.
MIVA Direct Imagers are designed to meet the varied needs of the PCB industry and although technological improvements have allowed us to address other market sectors, the PCB industry remains our biggest customer. Quality, speed, accuracy, compatibility, customer service, reliability and a fair price for new machines and maintenance are what the industry demands, and what MIVA Technologies offer.
