Pressure sensors in air conditioning technology, especially in heating and cooling systems, measure precise pressure conditions to ensure optimum functionality and efficiency. They monitor the pressure of refrigerants in the systems, which is crucial for their performance. The measurement is made by converting the pressure into an electrical signal, which can then be analyzed and controlled.
Ceramic pressure sensors: Robust high-performance ceramics for maximum efficiency and safety in air conditioning systems
Ceramic pressure sensors are particularly relevant in this context due to their specific properties. The core of the sensor, the circuit carrier with the electronic components, is made of a hard-brittle material – high-performance ceramics. This has excellent strength and resistance to high temperatures, wear, deformation and chemical influences that can occur in heating and cooling systems. They also offer precise measurement accuracy and a fast response time, which is crucial for real-time control in such complex systems. Overall, ceramic pressure sensors make a significant contribution to ensuring the efficiency, safety and longevity of heating and cooling systems.
Challenge and solution in the machining of high-performance ceramics for extreme requirements
On the one hand, high-performance ceramics have the best material properties, but on the other hand, the hard and brittle material and the delicate layouts mean that there are special requirements when processing ceramics.
Only with many years of expertise in the laser fine machining of such sensitive materials can extremely precise, delicate precision components, such as customer-specific substrates for electronic circuits, be manufactured gently using modern laser technology, which are then used as sensors under extreme conditions and have to impress with their robustness and reliability - whether in heating and cooling technology with strong temperature fluctuations or in other applications such as in special manufacturing processes under high vacuum, at extreme temperatures in space or when explosion protection is required for gas mixtures or maximum stability in human medicine.

Precise laser processing and versatility: our expertise and technological processes for sensitive special materials
No challenge for LCP Laser-Cut-Processing GmbH. Our expertise lies in the variety of laser processes paired with the procurement and processing of sensitive special materials. The following processes are used for processing high-performance ceramics (aluminum oxide, aluminum nitride, zirconium oxide, silicon carbide, silicon nitride), whether as thin-film or thick-film substrates, as well as glass and silicon:
- Laser fine cutting: clean cut edges without reworking thanks to modern CO2 laser technology
- Laser structuring: Micromachining of complex surface structures on three-dimensional objects with innovative USP laser technology
- Laser scribing: Insertion of scribe lines for mechanical separation of the payload in the individual components for the production of circuit carriers
- Laser drilling: contactless and rework-free micro-drilling of precision holes, so-called vias, using USP laser technology
- Wafer dicing: extremely precise separation of wafers and substrates with exact edge quality using mechanical cut-off grinding (sawing)
With laser marking, a particularly safe, fast and sustainable method of marking components without contact and without damaging the material, a permanent data matrix or QR code can then be applied to the respective component, which later guarantees complete traceability of the respective component.
