Background:

Sensors is a renowned automotive sensor manufacturer known for their commitment to innovation and delivering high-quality sensor solutions. They approached us with the objective of enhancing the precision, durability, and reliability of their automotive sensors to meet the evolving demands of the automotive industry.

Project challenge:

The outline tolerance is very strict, only positive tolerance is available.
The project requires high wear resistance, so the conductor should include high content of Palladium, but it is not easy to protect the palladium surface from oxidation.
The quality control must be proceeded with IPC class III.

Solution:

According to the requirement, we choose thick film technology for them. Thick film ceramic circuit boards have found extensive use in automotive sensors, which play a critical role in modern vehicles. These sensors are responsible for collecting and transmitting important data related to engine performance, emissions, safety, and more. By utilizing our thick film ceramic circuit boards in sensor designs, automotive manufacturers can achieve enhanced precision and reliability.

In this case, our ceramic circuit boards facilitate precise signal transmission, minimizing signal loss and interference. The excellent thermal management properties of the boards ensure consistent performance across a wide range of operating temperatures. Additionally, their robustness and resistance to harsh automotive conditions, such as vibration and moisture, ensure the longevity and durability of the sensors.

Result and Benefits:

We got consistent orders from Sensors, and they provide forecast to us every year, that we can prepare the raw material in advance, and produce the ceramic PCBs within 1.5weeks after receiving the purchase order.
