VESTAMID® HTplus for three-dimensional interconnect devices

(PresseBox) ( Essen, )
In VESTAMID® HTplus, Evonik Industries is offering a new-generation PPA that is customized precisely to the requirements of the laser direct structuring (LDS) process. With its outstanding heat resistance, the product is particularly suitable for use in lead-free soldering processes.

VESTAMID® HTplus, which is reinforced with glass fibers and mineral fillers, is available as 50% bio-based PA10T, which has a particularly wide processing window and an extremely low water uptake, and as PA6T/X, which possesses a higher thermal resistance. Both grades exhibit excellent chemical resistance. Their good processability and excellent thermo-mechanical properties make it possible to manufacture high-quality components.

The process

Laser direct structuring stands for freedom of design, miniaturization, and precision of electronic components. This technology allows to generate metallic conducting structures directly on the surface of three-dimensional plastic substrates. Many applications already make use of this process, for example, cell phone antennae and computers, medical devices, and automotive electronics. Manufacturing by means of injection molding ensures the greatest possible freedom of design.

On the surface of the plastic part, an infrared laser beam produces a preliminary structure -as a microscopic rough surface- that corresponds to the subsequent layout of the conducting paths and also provides chemical-physical activation in this area. This activation is made possible by means of a special additive in the plastic. In the subsequent metallization step, conducting paths are selectively generated that are firmly anchored to the surface.
