Pre-Placement Printing Process Solutions
The modern manufacturing environment is continually developing, subject to advances in technology, legislative requirements and end user demand. However, consistency remains a valuable commodity, particularly in the field of pre-placement print process control. That’s why DEK has extended its range of squeegee products, guaranteed to deliver the continual optimisation of pre-placement solutions.

Lead Free Chrome
The changing paste properties associated with lead-free raise significant implications for the whole print process. Going lead-free is so much more than merely substituting lead-rich paste for different alloys. For example, lead-free alloys will react differently with fluxes, affecting reflow profiles, residue characteristics, wetting performance, cleaning methods and processing time.
As a consequence, it is imperative that manufacturers are equipped not only to optimise paste transfer and alignment, but also to eliminate the prospect of contamination with lead-rich paste. Following extensive application test trials by our Lead-Free project team, DEK has developed a new range of chrome coated stainless steel squeegee blades and ProFlow® wipers to achieve exactly this.
The chrome material encourages improved lead-free paste rolling characteristics, preventing paste sticking to blades and wipers. For manufacturers, this means improved transfer efficiency, effective alignment and lower paste wastage for a superior, cost-effective lead-free performance.
All DEK chrome coated squeegee blades are identifiable by an engraved DEK Lead-Free logo, enabling easy distinction from regular squeegee blades.
The introduction of engraved part numbers on the new blades facilitates easy re-order.
A green anodized squeegee assembly is also available, further enhancing manufacturers’ ability to identify lead-free printing lines.
