Glass Micro Bonding by SCHOTT Primoceler

Miniaturization, enhanced functionality, and performance in harsh environments are becoming standard requirements for electronic components. Using a laser-based approach that delivers high precision, Glass Micro Bonding is opening new doors in hermetic sealing for applications that are shaping our future.

A new breed of ultra-miniature and reliable hermetic sealing

Gas-tight sealing

Glass Micro Bonding creates a fully hermetic seal, offering complete protection for encapsulated components – even in harsh and inaccessible environments.


The latest technological developments offered by SCHOTT Primoceler enable chip-size components smaller than 1 millimeter.

RF Transparency

Transparent glass encapsulation eliminates the need for wired connections as radio frequencies (RFs) can travel through the all-glass package. This reduces bulk and complexity in device designs while allowing devices be Internet-connected by emitting and receiving over-the-air data signals.

Flexible customization

SCHOTT Primoceler R&D experts will work with you at every step – from concept to volume production – to overcome your development challenges to create a customized component.


Up to the challenge: SCHOTT Primoceler Glass Micro Bonding is a proven superior alternative to existing sealing methods including anodic bonding, direct/fusion bonding, glass frit or epoxy (UV or thermal) encapsulation.
