1.1 LPKF ZelFlex Z4P
ZelFlex frames are designed for holding SMT metal stencils tensioned during the SMT printing
process.
The ZelFlex frame size should be selected according to printer data, either for direct inserting,
or using adapters.
When the printer supports various sizes of frames, frame holders must be adjusted to the
ZelFlex frame size.
The ZelFlex patented stretching system uses compressed air for perfect and uniform tensioning
all over the working area. Two major ZelFlex Z4P types are available - standard and slim.
Standard frame has thickness of 33 mm, whereas Slim of 25 mm. This type was designed
especially to fit into smaller printers with height limit of 25 mm. Thinner frame acumulates less
air inside and for this reason it needs fill up time at least every 24 h.
Compressed air is kept inside the frame and provides optimum tensioning for the next 24/48 h
depending on the frame type.
Different supplied air pressure levels allow optimum tensioning of stencils from 100 microns
(4 mil) to 250 microns (10 mil). Details can be found inside the manual.
When stencil is mounted, air supply is disconnected. A frame can be inserted into the printer,
and used for at least 24 hours without the need for air connection.
LPKF ZelFlex Z4P is available in many different sizes and with different adapters suitable for
almost all printing machines.
