Reliability in extreme condition


For every aerospace application, reliability is of the essence. Primoceler’s bonding technology offers reliable all-glass packages, which deliver high stability in harsh environments.

Key benefits

  • High hermeticity ›› Reliable device operation
  • No additives ›› Outgassing issues minimized
  • All-in-glass package available ›› CTE issues minimized

Reliability beyond expectations

In aerospace applications, hermeticity is very important, supporting long device lifetime in extreme conditions. Visual inspection is also crucial when verifying device reliability. SCHOTT Primoceler’s glass packages allow a simple way of looking into the devices, making visual inspection without the use of X-rays possible.

Bonding technology for opto-electric devices

SCHOTT Primoceler‘s Glass Micro Bonding enables the manufacture of optical sensors and opto-electric devices, such as high reliability VCSEL and photodiode devices. The bonding method does not need additive materials, mitigating outgassing issues. Furthermore, challenges due to thermal cycling can be avoided.

Room temperature vacuum sealing

Applications such as IR microbolometers, atomic clocks, and inertial sensors require hermetic vacuum sealing, which must be absolutely reliable in order to support long-term device performance. Vacuum seals are also used to protect MEMS devices. SCHOTT Primoceler Oy can perform vacuum sealing at room temperature and a controlled gas environment can be sealed inside the device.

Experience from ESA projects

SCHOTT Primoceler has been working on various projects together with the European Space Agency. Our vast experience in aerospace applications means the quality and workflow of predefined processes are part of our daily work.

MIL standard testing

SCHOTT Primoceler has performed environmental and mechanical testing on its bonding methods. Testing was executed according to military standards for space applications. Moisture resistance, thermal cycling and hermeticity have all been verified. Find out more about the technology and test results.
