Thick Film Hybrid Sensors


BHC develops and produces hybrid sensors or carriers for sensors on behalf of customers. They choose this because of the durability and quality, accuracy and good properties of the ceramic. These include the breakdown voltage, stability, temperature resistance, thermal conductivity and 0% moisture absorption.

The (thick film) hybrid circuits and the screen printing of pastes (including conductors, resistors, glass and polymer on ceramic substrates, which are then dried and sintered) were largely used for the aerospace, medical and automotive industries. They choose this because of its reliability, reproducibility, chemical resistance and temperature stability. However, this technique is also increasingly finding its way within the telecom, lighting, consumer, office and general industrial markets. You can visit our facilities in 's-Heerenberg to see how hybrids are made. Also take a look at our projects and markets to see the application possibilities.

Why a hybrid sensor or sensor carrier?


To determine this, we need to understand the properties of ceramics and the screen printing process (download the PDF with the substrate properties here) To determine this, we need to understand the properties of ceramics and the screen printing process (download the PDF with the substrate properties here). Hybrid technology is very eco-friendly because it uses materials that come from nature, and the product is recyclable and very sustainable. It’s an additive process (you only use material you need). Ceramics are widely used for temperature, angle, pressure, flow and much more. On this ceramic substrate, temperature-dependent resistors can be printed, with or without a heater.
Components, such as SMD components, semiconductors, mems and the like, can be placed at a later stage. They are mainly placed for the measurement values, and if necessary, also with integrated electronics for further control. These sensor modules can then be actively or passively adjusted to the desired value.

In addition, ceramics are more temperature resistant, more mechanically stable, have a higher breakdown voltage and do not age. On these sensors or carriers, we can solder wires, place connectors or make contact surfaces. This so that the assembly in the application is simple. However, the fragility during assembly must be taken into account.
