Method
The DPP method
The Dry-Phase Patterning (DPP) method allows us to manufacture conducting structures on flexible materials like metals, paper, or plastic. Using a principle almost as simple as punching a hole in a paper. To put it short, a cliché presses out your desired pattern on a material, or “web”, consisting of a conducting top layer and a dielectric bottom carrier. A milling wheel then mechanically removes the protruding pattern from the top layer (the pattern layer). The bottom carrier remains untouched. This leaves a conductive pattern on the laminate. This patented process brings you instant advantages, such as increased cost efficiency, reduced lead times, and environmentally friendly, sustainable production.
Other applications
Our technology can also be used for non-electronic and non-conductive applications. Such as plastic or paper decor, or functional 3D structures, like micro-fluid channels or cavities for leveling electronic components.
With the DPP method you can use various types of organic material as the carrier. For example PET (Polyethylene terephthalate), PC (Polycarbonate), PI (Polyimide) or PEN (Polyethylene naphthalate). Depending on desired thickness and end result, use Al (aluminum) or CCA (Copper-Clad Aluminum) as top layer. The charts below show typical values for the different alternatives.
