Picosecond Laser Processing Equipment

nScrypt provides complete laser micromachining solutions for difficult applications. We incorporate picosecond lasers on our standard, precision motion platforms to deliver high quality micromachining capability to the semiconductor, electronics, aerospace, medical, solar and many other industries. When speed is more important, the nScrypt motion platform can be configured with other laser alternatives such as nanosecond and CO₂ solutions.

We understand that the right laser is only part of the solution. Having the proper optics for your process is equally important. With our deep experience in specialized optics, we will specify and integrate the optics your process requires; from beam shaping to spot size, we will precisely design for you.

Performance and Precision with our Picosecond Laser

With repetition rates up to 1MHz and high average power, solid state picoseconds lasers are able to achieve cost effective, high quality micromachining. With picosecond pulses there is little to no heat affected zone when machining. This benefit eliminates micro cracking of sensitive substrates. Compared to femtosecond lasers, picosecond lasers produce similar ablation characteristics, are easier to maintain, and can perform similar operations 5 times faster. Being able to obtain a power density in the TW/cm² regime allows for the micromachining of most materials.

Our team of laser experts is available to discuss the micromachining system right for you.

Laser Sintering

Laser sintering is easy when dealing with high temperature substrates. The complexity enters in when using lasers to sinter electronic materials or to thermally induce biological materials. nScrypt has mastered material handling in these instances. When using a laser to sinter a high temperature material on plastic, our method makes the difference between success and failure. No two materials are the same and this variety drives our focus on providing a solution.

Laser Ablation

Whether drilling vias, cutting edges, trimming resistors or milling patterns for layered electronics, the femtosecond laser demonstrates a clear advantage compared to traditional nanosecond lasers. In the photos below, both substrates are polyimide, a low temperature substrate. The photo to the left shows the surface bubbling and creviced. This is due to excess heat the nanosecond laser induces on the substrate. The photo to the right, using the same magnification, shows a smooth and polished surface.
