Laser pointer laser drilling and cutting system
Laser pointer:
LPKF has launched a flexible drilling system based on the MicroLine 5000 UV (UV) laser. LPKF (Garbsen, Germany) has launched a flexible drilling system based on the MicroLine 5000 UV (UV) laser. The size of the system is 21 x 24 inches. It can provide two work areas with different laser power levels, depending on the needs of different substrates and thicknesses. The laser pointer system is equipped with an accurate process monitoring system and an intelligent vision system for reference recognition and alignment. The system is primarily focused on fast drilling of blind and through holes, but can also be used for contouring flexible circuits. Green laser pointer The spot size of the laser beam is 20 μm, which can accurately cut complex flexible circuit shapes.
Green laser pointer:
Laser Pointer The laser system operates at UV wavelengths, allowing you to drill and cut fragile substrates with the smallest heat-affected zones. The system can also be configured for roll-to-roll processing of flexible boards.
Ultra-fast blue laser pointer laser can be used for micromachining thin glass
Blue laser pointer:
Scientists are studying how to use ultrashort pulse (also known as ultrafast) laser pointers to etch microstructures into thin glass. There may be applications in analytics (lab-on-a-chip), especially in the field of electronics and consumers. A special method of irradiating the glass with an ultrafast laser increases the sensitivity of the glass to subsequent wet chemical etchings by a factor of 1000. This means that a laser beam with a diameter of a few microns can pass through a glass block and be etched through a thin tube through a glass volume. If you are a laser pointer or DIY enthusiast, a laser engraving machine can be a very useful tool for you.
Laser engraving machine:
This method can be used to create minimal holes, etch a complete microfluidic system into glass, or make incisions with very high surface quality. There are some questions that need to be answered before this phenomenon becomes an industrial process. The answer to these questions is the Femto Digital Photon Production Joint Research Project, funded by the Federal Ministry of Education and Research (BMBF; Bonn, Germany). Since 2014, representatives of RWTH Aachen University (Aachen, Germany) and Fraunhofer Institute for Laser Technology (ILT; Aachen, Germany) have been studying the use of ultrafast laser pulses in the processing of transparent materials6 We have cooperated with the company. A new phenomenon. .. They have developed selective laser etching (SLE). It has been tested on a wide variety of glass materials such as quartz glass, sapphire, borofloat 33, and Corning Willow. Many people use laser pointers to repel pests and birds, especially crows.
Crow repulsion:

This method is very environmentally friendly. In Borofloat 33, the etching selectivity between the laser structured and unstructured regions reaches 1000: 1 and in willow glass it reaches about 100: 1. In the next phase of the project, experiments will be conducted at RWTH Aachen University, where complex simulations will be performed in parallel with Nonlinear Dynamics (NLD) in the Education and Research Department of the laser manufacturing process. The Chair of Optical Systems Technology (TOS) will focus on optimizing the optical system in the system. The researchers are working with three purple laser pointer laser light source manufacturers (Amphos, Edgewave, TRUMPF) and three laser pointer system suppliers (4JET, LightFab, Pulsar Photonics).
Purple laser pointer:
Their goal is to develop a multi-beam system for large surfaces and a small system for microprocessing. LightFab, a start-up company at RWTH Aachen University, uses SLE to manufacture 3D precision parts made of quartz glass. This laser pointer machine increases the productivity of subtractive 3D printing of glass parts for prototypes and series, and thanks to its high speed module, parts can be mass-produced in the SLE process. Project partners have seen many potential applications for this technology. For microfluidics, not only do you create channels in the glass material, but you also create nozzles and other microcomponents. Red laser pointer technology also has advantages in the drilling and cutting process. Etching allows for ablation of tension-free materials.
Red laser pointer:
This is advantageous, for example, when manufacturing interposer structures with semiconductor technology. We can manufacture structures with a size of less than 10 μm.
