FSLA — Laser Processing of Glass and Sapphire

Chemically strengthened glass and sapphire have outstanding material properties making them indispensable for use in electronics manufacturing. Application areas are cover glasses of watches, displays of mobile devices, protection windows for cameras, and LED or OLED carriers. This article reviews a sophisticated laser ablation technique that enables drilling of bore holes with well‐defined geometries ...

Ultrashort Pulse Lasers

Improving and Quantifying the Process Window

Femtosecond lasers bring numerous process‐enabling advantages to precision microprocessing applications. However, taking a new, ultrafast laser‐based application from a first demonstration to full‐blown manufacturing at market‐enabling throughput rates is usually more difficult than for longer pulsewidth lasers. This is because processes utilizing nanosecond (and longer) pulsewidth lasers can rely on a massive knowledge...

Additive Manufacturing

Alternative with a Future

The threat of a ban on hard chrome plating of metal components from the beginning of September 2017 in Europe has led to the development of new coating technologies and systems. Thermal spraying, which is already an established industrial process scores with its high flexibility, but for many applications, the quality of the created protected coatings remains insufficient. A real alternative for hard chrome plating is...

Laser Welding

Remote Laser Welding of Steel and Aluminum Alloys

Remote laser welded fillet and I‐seams at overlapped metal sheets are important joints for body‐in‐white production. Under ideal conditions such joints can be created in a welding‐friendly PA (flat) position with a zero‐gap between the parts. In Fig. 1, an example of a fillet welding process incl. a cross section of a typical weld seam at an aluminum door is shown.

Cost Efficient Diode Laser Beam Source for Sheet Metal Cutting

Diode lasers (DL) are widely used in a variety of different fields due to a long life time of up to 300,000 hours, a high electro‐optical efficiency of up to 70 %, a broad wavelength range — highest powers are available around 450 nm and from approximately 790 nm to 1060 nm — and a comparable low price.

Diode Laser Systems for Industrial Metal Processing

High power diode laser systems are widely spread in the industry. Whereas systems with several hundred watts are used for plastic welding and soldering, mainly in automotive, medical device and consumer applications, kW‐class diode lasers systems are used in metal processing applications to a large extent. Some direct beam applications use beam shaping to facilitate hardening of knife edges in industrial applications. The...

Application Feature

Laser + Camera = Innovation

The use of modern laser technology has become standard in industrial manufacturing thanks to its speed, accuracy and effectiveness. Lasers are used to engrave parts, electronic printed circuit boards or chip cards. They perforate packaging, structure semiconductor wafers, drill, cut and weld plastics or metals, and create highly complex structures via 3D printing — all contactless, with no application of force and...
