Hertzstück™ Infrared PbS sensors: Now directly bondable as bare chip

10 Nov 2016

• New encapsulation technique for photo conductors enables direct wire bonding of lead sulfide (PbS) sensors
• Automatization and miniaturization in the sensor assembly
• PbS sensors with a spectral range up to 2.9 µm available now, PbSe sensors with a detection limit up to 5 µm available Q1 2017

trinamiX GmbH announces a new brand of lead salt IR detectors under the trademark Hertzstück™. Thanks to a patent-pending encapsulation technique, Hertzstück™ sensors can be directly wire bonded to printed circuit boards as bare chips, without additional packaging.

Traditionally manufactured lead sulfide detectors require TO-packaging for environmental protection and long-term stability. These packages take up space, their placement is difficult to automate, and precise adjustment or alignment is complex. The thin film encapsulation process utilized on bare chip Hertzstück™ sensors solves many of these problems. Environmental influences like water and oxygen are eliminated. Package size and total footprint are reduced. The highly regular size and shape of bare chip Hertzstück^TM sensors make them well suited to automated assembly via pick-and-place robot. This combination of benefits means that with Hertzstück^TM many applications can be smaller, cost less to assemble, and have better alignment tolerances.

Hertzstück^TM Infrared PbS sensors are manufactured by trinamiX GmbH at a production site in Ludwigshafen, Germany and directly distributed. The detectors are available in the sizes 3 mm x 3 mm, 6 mm x 6 mm, and 10 mm x 10 mm. Other sizes and TO-packaged sensors are available on request. You can find detailed specifications at www.hertzstueck.de.

Besides the lead sulfide sensors, lead selenide (PbSe) sensors are being developed using the same encapsulation method, which are capable of detection up to a wavelength of 5 µm. PbSe sensors will be available in the first quarter of 2017. PbSe sensors are being used for gas analysis, flame detection and spectroscopy when a wider detection range is necessary.
