Control of the aperture characteristics, stencil thickness and accurate fiducial generation are directly related to the volume, alignment and positioning of paste deposited during printing.
Correct stencil design, coupled with quality manufacture, makes a significant contribution to end of line yield.
Superior Performance in fine-pitch, high density stencil manufacture is a direct result of the speed and precision of laser cutting.
Guaranteed tolerance of aperture dimensions to ±5µm over the entire printable area of the stencil makes for consistent and accurate replication of board features, even with large panels.
Laser cutting is fast,allowing us to offer standard 3-day manufacture, with the option of faster turnaround if required, and no compromise in the accuracy or quality of the stencil.
Stencils are generated from stainless steel, carefully selected for flatness and uniform thickness - important qualities in a precision stencil.
Intrinsic properties of the laser cutting process result in apertures with a trapezoidal cross-section, which allows excellent paste release.
The laser is a uniquely flexible tool; by adjusting the intensity of the laser during manufacturing, we can create high-contrast fiducials on the surface of the stencil with no need for in-filling and with extreme accuracy.
DEK's expertise also lies at the heart of our precision stencil cutting equipment, featuring pumped Nd-YAG lasers.
Our close involvement with the laser manufacturer ensures the highest levels of accuracy, repeatability and throughput; the foundation of a truly world class stencil service.
DEK ensures100% inspection of every stencil produced using a scanner as part of our final QA inspection.
Our European Network of stencil manufacturing facilities features consistent production and CAD equipment throughout.
This allows us to offer our European customers the same excellent quality, accuracy and turnaround from our offices in the UK, France, Germany, Benelux and Hungary.
When you source your stencils from DEK, you automatically gain access to our extensive knowledge of the pre-placement process.
Potential process problems can be avoided through optimal stencil design, bringing calculable benefits in production - many of the uncertainties you will face when specifying a stencil have already been encountered and solved by DEK.
Our unmatched understanding of the issues involved in pre-placement is fundamental to producing quality stencils, perfectly matched to your process from the outset.
