In the last few years, innovation has ramped up across materials, processing methods, and system integration. The drivers? Higher data rates, smaller devices, hotter systems, and a growing need to push performance without compromising durability.

Here’s what’s changing fast:

1. Miniaturization Meets Multi-Layering

Manufacturers are now producing LTCC modules with over 40 internal layers, embedding everything from inductors to filters to antennas. This isn't just about stacking more functionality—it’s about reducing signal loss, noise, and cross-talk within tightly packed designs.

One RF engineer at a telecom supplier noted: “LTCC lets us build a full duplexer the size of a postage stamp—with no external shielding needed.” That kind of footprint shrinkage is becoming the norm in 5G and millimeter-wave designs.

 

2. HTCC is Evolving Toward High-Voltage Applications

While LTCC dominates the RF side, HTCC is moving into power territory —especially in automotive inverters, onboard chargers, and aerospace actuators. Materials like alumina and zirconia are being modified to withstand higher dielectric fields and rapid thermal cycling .

A number of European automotive suppliers are prototyping HTCC-based IGBT substrates as alternatives to traditional DBC (Direct Bonded Copper), which are expensive and less stable under thermal shock.

 

3. Additive and Hybrid Manufacturing

The use of inkjet and screen printing for embedding passive components into LTCC layers is picking up. Also, laser-based via formation is replacing mechanical drilling in many fabs, improving precision and yield.

For HTCC, co-firing with tungsten-paste printing is being refined to allow for better conductor line resolution—making the material suitable for more compact device designs, not just power blocks.

 

4. System-in-Package ( SiP ) Integration

To be honest, where the ceramics are made isn't as important as where the systems are designed . And right now, the most strategic system designs—from radar arrays to EV drivetrains—are demanding more from LTCC and HTCC than ever before.

 

End-User Dynamics And Use Case

When it comes to LTCC and HTCC adoption, not all end users are looking for the same thing. Some prioritize thermal reliability, others care about signal integrity at high frequencies, and a growing number want miniaturized, integrated solutions. What ties them all together? The need for ceramic platforms that can keep pace with the next generation of high-performance systems.

Let’s unpack how different players in the value chain are using LTCC and HTCC—and what that means for market direction.

1. Original Equipment Manufacturers (OEMs)

These are the core adopters of LTCC and HTCC. They’re building everything from radar modules and EV inverters to implantable medical devices.

• Telecom OEMs embed LTCC into RF front-end modules, antenna-in-package (AiP) systems, and power amplifiers. The priority? High-frequency performance and compact integration.

• Automotive OEMs prefer HTCC for critical systems—battery sensing, power conversion, and LED controls—where thermal cycling and vibration are constant.

• Aerospace OEMs often co-develop HTCC-based boards with defense contractors for avionics and communication systems that must operate in extreme environments.

These OEMs aren't just buying substrates—they're asking vendors to co-design packaging solutions that align with long-term roadmaps.

 

2. Tier-1 & Tier-2 Automotive Suppliers

Suppliers serving top automakers are rapidly integrating HTCC into EV architectures.

• Battery Management Systems (BMS)

• Onboard chargers (OBC)

• Power control units (PCUs)

The logic is simple: HTCC outlasts organic substrates under thermal stress, and it’s smaller than traditional metal-core boards. That gives suppliers an edge in energy density and reliability.

Some Tier-1s are even using co-fired HTCC ceramic modules as replacements for aluminum oxide-based housings, citing better EMI shielding and life expectancy.

 

3. Medical Device Manufacturers

In the medtech space, HTCC is a hidden hero.

• It’s used in implantables like cochlear implants, defibrillators, and pacemakers, thanks to its biocompatibility and hermetic sealing properties.

• HTCC feedthroughs and housings protect electronics from bodily fluids, while maintaining consistent signal transmission.

There’s also emerging use of miniaturized LTCC-based biosensor platforms, particularly in diagnostic patches and portable analyzers.

Unlike other industries, medtech prioritizes ultra-high reliability over cost—and that plays to HTCC’s strengths.

 

4. Defense Contractors and Aerospace Integrators

For this segment, LTCC’s value is clear: stable signal propagation at high frequency, compact form factor, and resistance to environmental stress.

• LTCC is the substrate of choice in phased-array radar modules, satellite transceivers, and missile guidance systems.

• HTCC is used in inertial measurement units (IMUs), power control units, and space-grade packaging, where temperature swings are extreme.

What sets this segment apart? Most designs are ITAR-restricted, meaning suppliers must often be U.S.-based or certified for defense contracts. That narrows the competitive field and makes domestic supply chains a strategic advantage.

 

5. EMS & Contract Manufacturers

In Asia and parts of Europe, contract manufacturers specializing in RF modules and power components are adopting LTCC for quick-turn projects.

• These firms often cater to fabless design houses that want rapid prototyping, low-NRE tooling, and scalable volume without quality compromises.

• HTCC adoption is more limited here due to cost and complexity, but demand is rising for hybrid assemblies.

 

Use Case Highlight

A leading EV supplier in Germany was facing high failure rates in its battery control module due to heat cycling and corrosion in humid climates. They replaced traditional organic substrates with a custom HTCC ceramic module co-developed with a local ceramic vendor. After deployment, warranty claims dropped by 38% in one year. Field reliability improved, and the company is now using HTCC across two additional vehicle platforms.

This wasn’t just a materials swap. It was a supply chain shift that unlocked long-term cost savings and customer satisfaction.

 

Bottom Line

End users in this market aren’t just choosing substrates—they’re choosing risk reduction, performance headroom, and product longevity. LTCC fits the bill when size and signal quality matter. HTCC steps in when reliability and durability come first. Vendors that can tailor solutions to each end-user segment—without over-engineering or overshooting the budget—will stay ahead.

  With dimensions under 2 mm, this system supports both Bluetooth and sub-GHz bands. It’s now being tested in asset trackers and medical wearables in Asia and Europe.

• CTS Corporation secured a DoD contract to develop LTCC-based RF systems for next-gen radar
  In late 2023, CTS was awarded a multi-million-dollar contract to co-design ceramic-based packaging for phased array modules used in airborne radar.

• A European R&D consortium began prototyping photonic-integrated LTCC substrates
  Backed by Horizon Europe funding, this 2024 initiative explores embedding optical waveguides within LTCC layers—targeting applications in quantum sensing and LiDAR systems.

 

Opportunities

• Next-Gen EV Platforms Need Better Thermal Packaging
  As OEMs shift toward 800V EV architectures, the demand for HTCC modules with high thermal resistance is rising fast. These ceramics outperform organic alternatives in high-heat areas like power inverters, battery sensor units, and DC-DC converters.

• Growth in Defense and Satellite Communications
  LTCC’s signal stability, miniaturization, and shielding make it ideal for military RF modules, satellite payloads, and guided weapon systems. Ongoing defense spending globally is expanding this demand, especially in the U.S., Israel, and parts of Europe.

• AI-Powered Wearables and Compact Devices
  LTCC is becoming the substrate of choice for ultra-small, multi-band wireless modules. As AI moves to the edge (think: smart earbuds, diagnostic patches), ceramic integration allows manufacturers to hit size, heat, and power targets that PCBs simply can’t.

 

Restraints

• High Capital Costs for Substrate Manufacturing
  LTCC and HTCC production lines require expensive kilns, cleanroom processes, and precision layering systems. That makes entry tough for new players and limits supply expansion. Smaller EMS firms often struggle to justify in-house ceramic capability.

• Limited Skilled Labor for Ceramic Design and Integration
  Designing multilayer ceramic substrates isn’t the same as designing PCBs. Many engineering teams lack the in-house materials knowledge or EDA tools optimized for co-fired ceramics. This slows down prototyping and makes design handoffs more complex.
   

To be honest, this market isn’t short on demand. It’s short on scalable expertise and cost-flexible supply chains. The vendors that can solve for those two gaps—through partnerships, training programs, or modular ceramic systems—stand to win disproportionately.
