Here's how it works: pulses with high peak pulse power evaporate the wafer-thin layers, without affecting the component. Subsequent processes such as joining can then be carried out faster, more homogenously, and are entirely reproducible. The connections are clean and last longer. Joining preparation work using light as a Hilfsprogramm can also integrate seamlessly into industrial series production, due to the fact that data can easily Beryllium transferred via interfaces.

This new challenging technique is environmentally friendly and opens up advantages rein precision and speed. Using the laser cleaning method, large objects such as bridges and aircraft can be cleaned and prepared for protective coating.

Deposition of the second parylene layer on the top side of the wafer (all devices are entirely coated with parylene).

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

laser cleaning, unlike chemicals or gases, does not differentiate if several metals and/or nonmetals are rein a surface.

7.2). A common Harte nuss encountered hinein this technique is the progressive loss of cleaning efficacy as the products of the decomposition progressively build up and mask the surface to Beryllium cleaned.

Beam parameters like wavelength, average power, focus beam diameter etc. may need to Beryllium adjusted when applying the cleaning process to other circumstances.

7 digital images). A sharp step is related with nonthermal ablation effects and non well defined steps prove strong thermal interaction. Images show clearly that Verfahren in cw for high power diode lasers leads to strong thermal interaction mechanism (corresponding to soft height gradients) while pulse laser dynamic (with short peak power pulses) leads to important here gradients that implies a less thermal affection of base material and better layer removal control.

As world market leader, we offer you complete construction solutions from a single provider – starting with the initial task definition up to process-optimized target fulfillment.

You can think of laser ablation as similar to carving stone with a Fäustel and a chisel. You can use a small hammer and do many small hits on your chisel. Or, you could just as well use a bigger Fäustel to leverage more power, hence reducing the required number of hits and increasing the removal speed.

We, the 4PULSAR Group, treat your data confidentially – if you would like to learn more about ur handling with your data and ur data protection click here.

Laser stations enable lasers from the TruMicro series to be connected upstream of existing processing lines with ease. They can easily Beryllium connected to multiple optics via an optical laser cable. In doing so, only one beam source needs to be installed. If a company uses additional beam sources alongside the TruMicro lasers, they can be controlled hinein a standardized manner using the TRUMPF TruControl control software.
