PhotoMachining Partners with Light-Fab for SLE

Pelham, NH — PhotoMachining has partnered with Light-Fab GmbH in a collaborative effort to promote selec- tive laser etching (SLE) with femtosec- ond lasers in the U.S. According to PhotoMachining, the

unique nature of very short pulsed light enables such processes as SLE, which cannot be done with longer pulse lengths. Light-Fab sees poten- tial for the technology in the U.S. mar- ket, especially in the fields of medical devices and electronics. The SLE process involves

exposing hard, brittle and otherwise transparent materials, such as quartz and fused silica to USP laser light and then chemically etching the exposed area away. Etching selectiv- ity after laser exposure is enhanced over a thousand times. This method can be used to make precise 3D parts by essentially 3D printing the pat- tern inside the bulk of the material. The technology is expected to play a growing role in technology, such as microfluidics.

sion laser job shop and systems inte- grator. Light-Fab is the developer of

enables reliable, bubble-free applica- tion of bonding materials and the subsequent joining of components. The process cuts the scrap rate near- ly to zero. The bonding material is applied and the components are joined in vacuum environ- ments. The thin-film degassing technology of the single compo- nents makes it possible to process highly-degassed bond- ing material. Degassing of undercuts and the gap between the frame and display is also performed while the material is being applied. This mini- mizes the risk of air bubbles being trapped during the join- ing and curing process. Application is performed

by the RAMPF DC-VAC vacu- um dispensing system. Designed to process one- and two- component casting materials, it is fit- ted with vacuum material condition- ing as standard and equipped with a dynamic mixing system. The encap- sulating process can be easily moni- tored and adjusted through its large viewing window. A comprehensive range of mon- itoring equipment facilitates process

control, while the vacuum chamber can be configured for manual filling or for integration into automated systems. The company also offers turnkey solutions for all optical bonding processes. In addition to the display joining method in a vacuum, the fully-automated production sys- tems also include all the operations necessary to bond displays to frames. The company has developed a

range of liquid, optically-clear adhe- sives that exhibit excellent optical and mechanical characteristics. Key features include: 100 percent trans- parency, total clarity and very low

Mundt Releases Seven-Axis Laser Workstation


Mira 230 has a new robust and

sturdy design that supports an extraor- dinary processing range from AWG 32 to AWG 8. It sets a new benchmark by its unique sequencing capabilities that can be stored in a library for quick reproduction. The Mira 230 can strip and cut inner conductors with a variety of parameters without a program change. It comes equipped with a simple graphical user interface that ensures a quick learning process.

Scottsdale, AZ — Mundt has intro- duced its DB-241218, a seven-axis, ultra-short pulse laser workstation for use in a variety of industrial applications that require cost-effi- cient and precise micro- machining. The pulsed lasers, approximately 100 femtosec- onds to 10 picoseconds, per- form such tasks as cutting, drilling, marking, and other surface modifications. Ultra-short pulse laser

energy ablates without heat- ing, creating no heat-affected zone. This improved process can enable new and more com- plex product designs, improve product reliability, and lower operating costs. The company is aiming its

laser manufacturing tools at the medical device, aerospace, high-end automotive, and consumer electron- ics industries, as well as other fields that require extreme precision. The new workstation combines a carte- sian system and a galvanometer to offer more scope and capabilities, addressing many general industrial requirements.

The complex ultra-short pulse

laser utilizes infinite field of view (IFoV) and enables seamless machin- ing over large areas. The machine is able to move from large to small
