Growing Popularity of Low-Temperature Co-Fired Ceramics Technology
The low temperature co-fired ceramics (LTCC) sector is one of the modern world’s rising markets, contributing significantly to global gross domestic product (GDP).
The expanding popularity of LTCC technology has been seen notably in consumer electronics, vehicle electronics, aerospace, military, and other areas. American Technical Ceramics Corp., for example, manufactures military-approved porcelain and ceramic multilayer capacitors, which are high-frequency fixed ceramic chip capacitors produced using LTCC technology.
What is LTCC?
Low-temperature co-fired ceramics (LTCC) is a substrate technology that supports active and passive components and provides dependable, high-density electrical connectivity. Its layout is comparable to that of a more traditional multi-layer Printed Circuit Board (PCB), but its ceramic technology is more suited to radio and microwave frequencies, as well as harsh working conditions with high temperatures and mechanical pressures.
LTCC is ideally suited for applications that can benefit from one or more of the following features:
• Good electrical performance.
• Dimensional and electrical stability under temperature, moisture, and mechanical stress.
• High density via integrated passives and bare semiconductor die.
• Hermeticity.
• Matched thermal coefficient of expansion (TCE) with semiconductors.
• Various assembly and packaging solutions.
Consistent technological advancements in the electronics, military and aerospace sectors are projected to fuel the market expansion of LTCC. According to BIS Research, the global low temperature co-fired ceramics market is expected to reach $8,410.7 million by 2031, with a CAGR of 7.6% during the forecast period 2021–2031.
Advantages of LTCC
The following are some of the benefits of LTCC technology:
· It offers good electrical performance with improved dimensional and electrical stability under severe temperature and stress.
· The thermal expansion is coefficient than that of a typical PCB.
· Because it avoids interconnections by using passive components, LTCC is said to be more dependable than PCB.
Opportunities in LTTC Sector
Automotive Industry: The introduction of autonomous vehicles (self-driving automobiles) has increased the demand for sensors and antennas. The use of LTCC allows for a high level of integration while also allowing for a small sensor module and it is also utilized in automobiles for circuits with a high component density that requires durability in hostile conditions.
Many control circuits for traction and stability, hydraulic and antilock brakes, electrical assisted steering systems, engines, and gearboxes, for example, use LTCC. As a result, expanding electronic usage combined with the growing global automobile industry is expected to drive demand for the LTCC technology. It also provides prospects for LTCC makers, as their products are projected to be embraced by an industry with significant development potential.
5G Technology: 5G technology is quickly gaining popularity as the next generation of communication, enabling high-speed, large-capacity, and low-latency connectivity. Millimetre-wave communication, which ranges from 28 GHz to 40 GHz, is used in 5G communication.
LTCC substrates are utilized on circuit boards and filters to handle such high-frequency signals because they have better characteristics than standard printed circuit boards (PCBs).
New micro and non-microelectronics: Low temperature co-fired ceramics are required for various innovative micro-and non-microelectronic applications. These include the development of fuel cells for use in energy conversion systems.
The LTCC technique has been used in hydrogen fuel cells to construct complex 3D ceramic structures in the integrated evaporator, mixer, reformer, and combustor (EMRC) system. The EMRC system is designed to produce hydrogen for portable polymer electrolyte membrane (PEM) fuel cells.

Introduction of Low Temperature Co-Fired Ceramics in Various Sectors
The technology’s increasing popularity has been seen mainly for applications in consumer electronics, vehicle electronics, aerospace and military, and other sectors.
Consumer electronics: The consumer electronics industry accounts for a sizable portion of the market. This is because of the miniaturization of electronic equipment with rising computing power, causing cooling challenges and consequently producing harsh operating conditions.
As a result, these electronic devices are subjected to more demanding operating circumstances, increasing the probability of failure/breakdown.
The use of LTCC technology in these applications allows these devices to resist the operating conditions while using more dependable electronics. Smartphones, tablets, laptops, and LED televisions are some examples of small electronic items.
Because of people’s current lifestyle, demand for these modern electronic gadgets is likely to rise at a healthy rate, resulting in an increased need for LTCC substrates and packaging.
Automobile electronics: The increased usage of electronics in the automobile sector has increased the demand for very tiny sensor modules, making this sector the most likely to adopt LTCC.
These sensors are used in areas such as traction and control, hydraulic and antilock brakes, engine and power transmission systems, and engine-controlled steering systems, among others, in automobiles. These components are exposed to complicated operating circumstances, which endangers the life of the sensors.
As a result, there is a chance that this technological equipment will fail. To address this issue, the usage of low temperature co-fired ceramics technology has gained traction in recent years since it improves the dependability of these electronic devices and ensures their safe functioning.
Aerospace Electronics: Micro electro-mechanical sensors (MEMS), such as gyroscopes and accelerometers, are used in the aerospace/aviation sector. MEMSIC, Inc. and KOSTAS MAKRIS are a few companies that provide gyroscopes and accelerometers for aircraft.
These sensors are microelectronic devices that are vulnerable to harsh climate conditions that might pose dangers to these electronic gadgets. Thus, LTCC technology ensures optimum reliability and performance in these sensors.
Military Electronics: The military uses LTCC because of the complicated operating conditions for military electronics, which pushes the sensors utilized in military radars and other applications to the limitations. This jeopardizes the sensor’s ability to function efficiently, and LTCC technology is used to overcome this obstacle.
To sum up, everything that has been stated so far, several variables influence the worldwide low temperature co-fired ceramics market. For example, LTCC’s popularity in the consumer, military, and aerospace industries has been fueled by increased miniaturization of electronics and rising demand for light-emitting diodes (LEDs). In addition, the usage of numerous sensors in various areas of automobiles that operate at high temperatures is driving up demand for low temperature co-fired ceramics.
