Netlink - Windows compatible queue manager.
Netlink runs from any PC on the same network as the plotter. NETLINK  allows MIVA imagers to be operated remotely via a local area network. NETLINK also allows plot queues to be easily set up for many different types of  photoresist, or other imaging  media. It does this by setting up the imager automatically to work with the medium currently being exposed, thereby reducing the chance of operational errors, and minimising the operator´s workload. A numbering  or coding system for imaged panels or films can also be set up in Netlink.

MIVA Bitmap Interpreter - for imaging of PostScript, TIFF und PCX data formats.

The MIVA Bitmap Interpreter allows imagers to expose bitmap data using data sources in various data formats, currently supported are:

PCX (1 and 8 bit)
TIFF (Uncompressed and Packbits format)

Imager driver and input data formats
The MIVA standard Imager driver is dedicated to imager control and input data rasterization. Driver upgrades are available on request and are free of charge in the guarantee period or as part of a service contract.
Optional input data formats are: PostScript, TIFF, PCX
Standard input data formats are: Gerber, RS-274X (Extended Gerber), HP-GL, Fire 9000.

The maximum media size is obviously determined by the imager bed size. The minimum media size however is an important factor in reducing media wastage and is either unlimited or very low (approximately 3” x 3”) depending on media type. Media can be used in standard sizes or cut to size before imaging. For maximum plot sizes of each machine, please refer to the product overview on this site. Custom size imagers can be built on request to meet exceptional customer specifications. Several custom MIVA imagers have been installed worldwide to-date. The largest plotter, now working in the UK, has a plotting area of 3m x 1.1m. The largest Direct Imager, operating in Germany, has a maximum media length of 6 meters.

All MIVA systems are flatbed, allowing exposure of panels, film, glass or chrome plates and eliminating any deformation of the medium during imaging. The medium is held in place during the imaging procedure and the area of the plot is exposed by one or more projectors mounted on a moving X-Y-Z table which moves in a plane parallel to the film. Because of this, the projected pixel size and therefore the line width or structure size is stable over the plotting area.

Light source
MIVA Direct Imagers and Mask Writers use  Quad Wavelength Semiconductor light sources  in each imaging projector. This allows exposure optimization of  our customer´s  preferred photoresist or solder mask type. For increased DI throughput, multi-head systems are available, also as an in-field upgrade.  Light Sources have a nominal lifetime of 20.000 hours and are in-field Swap & Go replaceable.

Resolutions, speed and imaging structure size
It is important to note that on all MIVA imagers the minimum structure size is directly related but not equal to the projected spot or pixel size. This is because a line or structure is constructed from several pixels which are placed slightly offset to one another. For example, on the MIVA 2025DI, a Direct Imager working in 10.000 dpi mode, the specified minimum structure size is not 2,54 microns (the pixel raster size) but is specified by us at 25microns, because MIVA imagers generally use at least 10 pixels to realise our defined minimum structures in high quality

Resolutions currently available range from 3000 dpi to 128000 dpi.

MIVA DI: We recommend to operate MIVA Direct Imagers in standard yellow safelight conditions. This avoids pre- or post-exposure of resist-coated panels or UV films.

MIVA Photoplotters or Maskwriters: A room with media-appropriate safe lighting is required for loading and unloading of films or masks. During exposure the imager is light tight and normal working lights can be switched on.
