SAN DIEGO, June 30, 2011 — Pulse Electronics Corp. has introduced its laser direct structuring (LDS) antenna manufacturing process for antenna parts that are too long or large to fit well into conventional laser machines. According to the company, the lasering process saves as much as 30% over manufacturing done with previous LDS lasering machines, making LDS antennas cost-competitive alternatives for laptop computers, tablets and notebooks.

High-radio-frequency performance 3-D-shaped antennas are increasingly needed to enable ever-smaller and -thinner mobile devices, especially in the desired round shapes.

The concept was developed based on LPKF Laser & Electronics’ new Fusion 3D 1100 laser machine, which is adapted with a Pulse Electronics-designed and manufactured part handling system. This newly developed system can laser long, large and complex parts. The process has fewer design and dimensional limitations, yet still meets production efficiency requirements.

LDS produces a high-performing 3-D antenna. The laser beam transfers the antenna design directly onto a molded 3-D surface, rendering prototyping and production faster. It enables design freedom and flexibility with quick versioning during the project phase, design freezing in the late project phase, and the ability to fine-tune the design during production to meet stringent carrier requirements. The production process is easy to implement, with low customer-specific tooling costs.

Pulse also manufactures cable assemblies that can be directly connected to all solderable materials.

The LDS process enables fast product ramp-ups and seamless transfer between research and development and manufacturing.
