TAMPERE, Finland, Jan. 20, 2017 /PRNewswire/ — Thanks to an on-going joint project with the European Space Agency, Finnish microfabrication solution provider Primoceler Ltd. (https://www.schott.com/primoceler) has developed a patented process to package vertical-cavity surface-emitting lasers (VCSELs) using no heat or adhesives. The resulting VCSEL packaging leaves the electronics hermetically sealed inside with absolutely no damage, regardless of the size of the packaged components. Now, Primoceler’s packaging will be applied to products in the autonomous cars, augmented reality, medical, and mobile device industries. “Traditional fusion and anodic bonding methods for packaging generate a considerable amount of heat, which can irreparably damage the fragile components inside,” explained Antti Määttänen, Primoceler laboratory engineer. “Primoceler’s Glass micro Bonding technique for VCSEL packaging, in contrast, produces a hermetic seal at room temperature without the use of heat or chemicals. The applications are numerous, from light detection and ranging, or LIDAR, in the self-driving cars, to medical devices, augmented reality devices, and even mobile phones.”

Selfdriving cars are also based on light sources as VCSEL.

Primoceler’s new glass VCSEL packaging brings the company’s global patent count to 10. Designed to safely encase optical transmission products without damaging sensitive electronics, the packaging’s hermetic seal protects against gases and moisture, while the absence of adhesives ensures the components are also free of particles. Through the company’s patented heat-free Glass micro bonding technique, a strong and permanent seam is created that allows the packaging to withstand extreme fluctuations in pressure and temperature.

Through extensive testing, Primoceler has applied its Glass micro Bonding to over 100 products across a range of industries. Consumers can expect the first products with the new packaging inside in 2017. Although it won’t be obvious to the casual observer, Primoceler’s state-of-the-art packaging process will ensure more reliable performance and longer product life for many electronic products.

“We have worked hard to create a product that can perform in a multitude of applications,” said Määttänen. “The entire Primoceler team looks forward to seeing products using our technology hit the shelves next year. In the meantime, we will continue to introduce new applications for our heat-free Glass micro Bonding technology.”
