Microfabrication Company Primoceler Unveils New Glass Welding Machine Producing Significantly Reduced Heat-Affected Zone

About Us

Primoceler is your developing partner specializing in laser micro welding and scribing of transparent materials globally.


Located in Tampere, Finland, one of the leading European hubs for laser and photonics industry and research, Primoceler partners with its clients to create success through new business opportunities. The company’s microfabrication solutions have not only improved manufacturing processes but also revolutionized microscale bonding of transparent materials and enabled completely new product portfolios and business opportunities in semiconductor industry and medical technology.

Sapphire’s cost-effectiveness, durability, high melting point, chemical inertness, transparency and capacity for optical transmission in visible, ultra-violet and near-infrared light make it a highly desirable material in several industries. For example, because of the material’s resistance to heat and chemical erosion, sapphire substrates are currently used in the manufacturing of many LEDs for mobile handsets, televisions, automobile headlights and general lighting.

What we do?

Our products

Laser Welding

Suitable materials for laser welding are for example most glass types and silicon. Fast laser process forms hermetic encapsulation within seconds. With conventional bonding methods like fusion bonding and anodic bonding, a lot of heat is generated which can cause problems with sensitive components. With our welding technology, the heat affected zone (HAZ) is just some micro meters.

Laser Scribing

The use of sapphire is growing rapidly in displays, LEDs and in cover windows. New picosecond laser based method improves processing speed and ensures good edge quality. Compared to traditional processes also running costs are lower since no consumables are required.
