The compound TECACOMP PEEK LDS black is optimised with black copper-chromite-spinel additives and mineral filler and enables LDS functionality. In the laser direct structuring (LDS) process, injection-moulded surfaces or housings can be provided with conductor track structures and equipped with SMDs (surface-mounted devices). By modifying the high-performance plastic, the coefficient of thermal expansion in the direction of the copper is optimised and the thermal conductivity is increased. The special Ensinger filler concept enables very fine conductor spacing (fine pitch).

TECACOMP PEEK LDS is the only PEEK with LDS functionality approved by LPKF Laser & Electronics AG. Components made from the Ensinger compound can be laser direct structured, reflow soldered and have a high adhesive strength of the conductor path. Through-hole plating by means of laser drilling (VIA) is possible with a very small aspect ratio.

Thanks to their special properties, TECACOMP PEEK LDS compounds are used in electrical engineering, mechanical engineering, medical technology, the automotive sector and offshore applications.

Typical areas of application are components on heating elements (camera, radar, lidar or sensors), safety elements (screw locking devices on wind turbines, components on lifts or roller coasters) or in microsystems technology (thermoplastic wafers, thin-film sensor technology or LDS transformers). Laser direct structurable high-performance plastics are also increasingly used in antenna applications in the 5G sector. Especially for high-frequency applications with >20GHz or when isotropic properties are required. Compared to LCP LDS, TECACOM PEEK LDS has a significantly better weld line strength and is therefore used in particular for components with critical holes and breakthroughs.

The base polymer PEEK has one of the highest heat resistances (up to 260 ℃ continuous use) and mechanical strengths among plastics. It is characterised by high purity, excellent chemical resistance, inherent flame resistance (UL94 V-0), low outgassing and outstanding radiation resistance.

TECACOMP PEEK LDS black is available as compound or filament. Sample plates (80 x 80 x 3 mm) and tensile test bars are available for laser and metallisation tests.

Ensinger is a member of 3D MID e.V. and has a very good network to support customers in project planning.
