Marking electronic components
The PowerLine IC-E laser from Rofin-Baasel UK (Daventry, Northamptonshire, UK; www.rofin.co.uk) is one of a family of fully programmable IC markers, specifically designed for the semiconductor industry, which uses solid-state laser technology to provide high-quality marking capability at high speed. This diode-pumped Nd:YAG laser combines fiber technology and high-speed marking heads to generate more than 1000 characters (1.0mm size) per second, enabling rapid processing of large batch sizes. The available wavelengths are 1064 and 532nm. The high-speed marking head provides a field size of 180 x 180mm (single head) or 300 x 180mm (double head). The marking contents can include any combination of alpha-numeric characters, logos, or machine-readable codes with no adverse effects on the system performance.
AMS Technologies Germany (Martinsried, Germany; www.ams.de) has introduced Quintessence Photonics’ (QPC) new member of its BrightLase Ultra laser family. The new module is designed to deliver very high power in a multimode fiber and for use in direct applications. The BrightLase Ultra-500 delivers up to 425W “cladding-free” output power. Standard wavelengths include 792, 808, 976, 1470, and 1532nm with fiber core sizes from 200–800µm. Custom wavelengths are available upon request. These modules feature optional on-chip internal grating BrightLock for wavelength stabilization and for higher spectral brightness. They are designed for direct-diode applications as well as fiber and solid-state laser pumping. Other features include a water-cooled plate with standard unfiltered water, detachable fiber, cladding free power and dichroic filter protection. Further fields of application include materials processing such as marking, soldering, welding, and engraving.
Laser control system
This new laser control system by Electrox (Letchworth Garden City, Hertfordshire, UK; www.electrox.com) has been designed as a 3U 19-in. rack-mounted or free-standing module that occupies 40% less volume than the previous 5U design. The unit is based on an entirely new series of components employing an innovative multi-processor design. This provides massively increased memory, which enables multiple large files and fonts to be stored locally. It also has a CAN-based expansion bus for highly flexible and versatile capabilities, providing axes control beyond more usual X, Y, Z, and rotary motion options. The company’s proprietary digital galvanometer control has improved algorithms and even higher performance, and provides a five-fold increase in the maximum pulse frequency capability.
High-power diode laser arrays
Dilas (Mainz, Germany; www.dilas.com) has introduced the only commercially available high-power diode laser arrays operating at 1940nm with wall plug efficiencies of >10%. With proprietary epitaxy, these high-power diode laser arrays can be principally integrated into all Dilas packages, ranging from single-bar configurations up to large-scale stack modules that can include hundreds of bars per module. Based on a single diode laser array, the company’s new generation 1940nm conduction-cooled, fiber-coupled diode laser modules generate output power of 6W, 12W, and 18W, using a standard 600µm fiber bundle with a numerical aperture of <0.22 and SMA-905 fiber connector. Easily integrated into OEM equipment, these sealed modules feature options like visible pointer, serial fiber interlocks, and user exchangeable protection window, providing maximum flexibility for integrating into larger systems. These diode laser modules are primarily targeted at the medical and industrial markets (materials processing applications).
Laser wire and cable marking machine
Laselec (Arlington, TX; www.laselec.com) has introduced the ULYS 990 Modena laser wire and cable marking machine suitable for cables used in aerospace, automotive, electronics, and other industries. It has new features such as an improved and more compact design, four printing fonts as standard, with two horizontal and two vertical orientations and 90 characters per font, including upper and lower case. It allows up to 128 characters per identification mark with specific information printed at cable ends, as well as bar code 39 printing capability. The Modena is also equipped with an exclusive process called “Twin Shots,” which enables the user to choose the appropriate production mode according to need. The Boost mode marks at an extremely high speed and is best for marking very long identifiers with small spacing and bar codes on wires and cables in reel-to-reel configuration using the Laselec re-spooler with no cutting.
Laser safety goggle
With filter type P1004, Laservision (Furth, Germany; www.lvg.com) has developed an attractive alternative to the previous alignment filter type P03, which is no longer available. It protects eyes securely against the laser radiation when working with “red” line, cross, dot, or pilot lasers in the milli-watt range. Type P03 worked only as an alignment filter in the wavelength range 620–644nm with the alignment protection level R1 and was only available in the frame style Skyline suitable for wearers of prescription glasses. The P1004, however, comes in both Laservision frame styles for plastic absorption filters Skyline and Lambda One and with both alignment protection level R1 for 625–650nm and R2 for 660–675nm according to EN 208 and with L protection levels DIR L5 for full protection according to EN 207.
The new StarWeld Integral system combines the Rofin-Baasel UK (Daventry,Northamptonshire, UK; www.rofin.co.uk) concept of manual welding lasers with a spacious working chamber and high average power. The system can be used in three operational modes:1) as a manual welding laser having excellent ergonomic design; 2) as a joystick-controlled deposit welding laser; and 3) as a high-precision CNC laser welding system. Incorporating four high-precision positioning axes, and with short set-up times and easy CNC programming, users can select as much automation as they desire, and perform the minimum programming necessary. The large working chamber provides space for objects with an edge length of up to 500mm. Motorized X, Y, and Z axes are designed to move workpieces with a maximum weight of up to 500kg quickly and precisely in all three planes, allowing rapid and accurate positioning of parts, from the most delicate to a heavy load. In addition, the optical system within StarWeld Integral can be swiveled around two axes, enabling processing of perpendicular surfaces, undercuts, or deep grooves without the need to turn or tilt the workpiece. Material with hardness up to 60HRc can be deposited onto all the most commonly used tool steels including 420 stainless steel (1.2083) and H13 tool steel (1.2344).
