Accurate, repeatable transfer of materials such as inks and special deposits for medical, defence, automotive and electronic applications can only be achieved with high quality, precision screens.
Around the world, emulsion screens designed and manufactured by DEK are used for specialist applications where precision and accuracy are of prime importance.
These include instrument panels for the automotive and aerospace industries, diagnostic indicator strips for the medical profession and for advanced electronic techniques such as flip-chip encapsulation, fine-pitch SMT and circuit fabrication using conductive inks.
Excellent Results are achieved through matching the characteristics of the screen - mesh and filament parameters, coating thickness, screen tension - with the properties of the transfer material and the requirements of the application (see tables).
Polyester screens give optimum performance when printing large images or using viscous print mediums. For ultimate control of resolution and deposit thickness, choose stainless steel.
Precisely adjusting the thickness of the screen coating gives further control. DEK was closely involved in developing the automated equipment that allows us to set a coating thickness to within ± 2 µm; a measure of the attention to detail offered by the world's best precision screen service.
Screen tension is equally vital to the accuracy and longevity of the screen. Precision stretching equipment allows this to be set within an accuracy of ± 2N/cm.
With the ability to process as standard, screens of 1m x 1.5m (larger sizes can be accommodated to order), we can satisfy virtually any application. Throughout Our European Network, DEK is equipped to respond quickly with custom-designed, precision screens.
We work closely with our customers, understanding their needs in order to satisfy individual requirements, such as maintaining a stock of pre-sensitised screens to ensure the fastest possible turnaround.
DEK is the first manufacturer of screens and stencils to achieve ISO9001 certification. This applies throughout our European network.
Find out more about DEK's unique solution by arranging to meet the people who will be creating your screens, by contacting your nearest DEK office.
