What Are the Different Types of Ceramic PCBs?

July 6th, 2024

Ceramic PCBs are a special breed of printed circuit boards known for their exceptional thermal resistance and durability. These PCBs are used in industries where high performance is critical, such as aerospace, automotive, medical devices, and power electronics. Nowadays, the most common types of ceramic PCB are thick film, DCB, DPC, AMB, HTCC, LTCC and thin film. In this article, we will introduce each of them in details.

What are the different types of ceramic pcbs?

Thick Film Ceramic PCB

Thick film technology is a process by using screen printing conductor paste and directly deposit slurry (conductor) on the ceramic substrate. Then sintering it under high temperature to form conductive circuit traces and electrodes, which is suitable for most ceramic substrates.

After the material is sintered at high temperature, a strong adhesion film will be formed on the ceramic circuit board, repeat this step for many times, a multi-layer circuit is generated.

You can print resistor or capacitor on the surface to get a interconnected structure. At EBest Circuit (Best Technology), we can make all the resistors with the same value, or different value for different resistor on the same board.

Thick film ceramic PCB has advantages on the simple manufacturing process, but it has some drawbacks that can’t be ignored:

Limited by the conductive paste and screen size
Line width less than 100um is difficult to achieved
Three-dimensional patterns are not available
Not suitable for fine-trace project

DBC / DCB Ceramic PCB

Direct Bonded Copper (DBC) or Direct Copper Bonded (DCB) ceramic PCBs are known for their excellent thermal conductivity. They are made by bonding a layer of copper directly onto a ceramic substrate, typically aluminum oxide or aluminum nitride. Due to the DBC technology is directly bond copper on the ceramic substrate, it can achieve thicker copper thickness to 300um. So, it is very suitable for high power applications.

The basic chemistry principle is to introduce an appropriate amount of oxygen between copper and ceramics before or during the application process. Copper and oxygen will form Cu-O eutectic liquid under 1065℃~1083℃. This is an important element in the manufacturing. DBC ceramic circuit board uses this eutectic solution to chemically react with the ceramic substrate to form CuAlO2 or CuAl2O4, achieving the combination between substrate and copper foil.

However, it is easy to generate micro-porosity between Al2O3 and Copper during the copper bonded process, and it doesn’t have a good solution by far. That is why the yield of DBC ceramic PCB is not good than DPC.

DPC (Direct Plated Copper Ceramic PCB)

DPC ceramic PCB utilizes direct copper plating technology, deposit copper foil on the alumina oxide (Al2O3) substrate. It is the most commonly used ceramic PCB in recent years. The circuit generated process is: pre-treatment – sputtering – exposure – develop – etch – strip – electroplating.

AMB (Active Metal Brazed Ceramic PCB)

AMB ceramic copper clad plate adopts the active brazing process, and the copper layer bonding force is higher than that of DPC, which is around 18n/mm – 21n/mm. AMB ceramic copper clad plate usually has a high binding force, usually makes thicker copper, between 100um and 800um. The AMB ceramic PCB generally rarely design traces or holes, even if there is a trace is very simple, the spacing is relatively wide.

HTCC (High Temperature Co-fired Ceramic PCB)

HTCC is a relatively early development technology, but due to the high sintering temperature (1300~1600℃), the choice of electrode materials is limited. Meanwhile, its cost is more expensive, these promotes the development of HTCC is relatively slow.

LTCC (Low Temperature Co-fired Ceramic PCB)

Although LTCC reduces the co-firing temperature to about 850 ° C, the disadvantage is that the dimensional accuracy and product strength are not easy to control.

Thin Film Ceramic Circuit Board

The thin film ceramic PCB is to deposit a metal layer directly on the surface of substrate by sputtering process. Through lithography, development, etching and other processes, the metal layer can also be graphed into a circuit pattern. Due to the low deposition speed of sputtering coating (generally less than 1μm/h), thin film substrate surface metal layer thickness is small and can prepare high pattern accuracy (line width/line space less than 10μm).

July 5th, 2024

With the gradual deepening of electronic technology in various application fields, the highly integrated circuit board has become an inevitable trend. Under this situation, the disadvantage of traditional circuit board FR-4 and CIM-3 in TC (thermal conductivity) has become a drawback to delay the development of electronic technology. Though the metal core PCBs are known for their good thermal management, they hard to meet the fast heat dissipation and miniaturization of the devices at the same time. This is why ceramic PCB stands out.

What is Ceramic PCB?

A ceramic PCB is a type of PCB made from ceramic materials, such as alumina (Al2O3), ALN (aluminum nitride), or Beryllium Oxide (BeO). These materials are prepared by using thermal conductive ceramic powder and organic adhesive under the condition of below 250℃. Ceramic powders are not easy to made, especially for aluminum nitride powder, this is one of reasons that why ALN ceramic PCB is more expensive.

There are some different methods to make ceramic PCBs, commonly in the market are thick film, DBC, DPC and thin film technology. Different types of ceramic circuit boards have its unique characteristics. May you heard about HTCC, LTCC and AMB, they are also the ways to make ceramic PCBs, but there just a few manufacturers can make. Here is a HTCC ceramic PCB that we made.

Why Ceramic PCBs are popular used?

High Speed PCB: How to Design It?

July 3rd, 2024

In today’s tech-driven world, creating efficient high speed PCB (Printed Circuit Board) is critical for ensuring devices can handle rapid data transfer without issues. These high speed PCBs are popular in the wireless devices which needs high signal transfer. Crafting high-speed circuits requires careful planning and precise execution to maintain signal quality and overall performance. In this blog, we introduced the basics of high-speed PCB design, offering practical tips and insights into the best materials and techniques for high-frequency applications.

What is a High Speed Circuit PCB?

High-speed PCB is a circuit board that can support signal transmission. High-speed signals usually refer to signals with frequencies higher than 50MHz, such as high-speed digital signals, high-speed analog signals, etc. These fast transitions can introduce challenges like signal reflections, electromagnetic interference (EMI), and crosstalk, which can disrupt performance if not properly managed.

Additionally, these signals will be affected by board materials, layout, wiring and other factors during transmission. Therefore, a specially designed circuit board is required to ensure the integrity and reliability of the signal. Here is a 4 layers high speed PCB for Iradar device with 50ohm single-ended impedance control.

Features of High-Speed PCB

High frequency

Low permittivity and low loss factor

Multilayer design

Strict impedance control

High-precision manufacturing

Low noise characteristic

High density circuit layout (micro-vias)

High performance

What is Considered High-Speed PCB Design?

High-speed PCB design focuses on managing the complexities that come with high-frequency signals and fast switching. Key considerations include:

– Signal Integrity: Ensuring signals travel without distortion or loss.

– Power Management: Distributing power effectively to minimize noise and voltage drops.

– Heat Handling: Managing heat from high-speed components to prevent overheating.

– Impedance Matching: Keeping impedance consistent to reduce signal reflections and loss.

– Differential Pair Routing: Reducing EMI and crosstalk by routing complementary signal pairs together.

This type of high speed pcb design requires a solid understanding of electromagnetic principles, advanced simulation tools, and precise manufacturing techniques. For those new to high-speed PCB design, EBest Circuit (Best Technology) offers expert guidance and solutions.

What’s the Best Material for High-Speed PCB Design?

Choosing the right material for high speed pcb is vital for maintaining signal integrity and achieving optimal performance. The material impacts the board’s dielectric constant (Dk), loss tangent, and overall signal quality. Common materials include:

– FR4: Widely used but not ideal for very high frequencies due to higher loss tangent.

– Rogers (RO4000 series): Preferred for high-speed designs thanks to its low dielectric constant and loss tangent.

– Teflon: Excellent for high-frequency applications but more expensive and harder to process.

Selecting the appropriate material ensures the PCB can handle high-speed signals without compromising performance.

Where is the High-Speed PCB Commonly Used in?

High-speed circuit boards are widely used in signal transmission applications, the typical fields are including:

1. Communication equipment – such as 5G base stations, optical fiber communication equipment, etc.

2. Data center – like high-performance computing, storage servers, etc.

3. Consumer electronics in our daily life – high-end smartphones, tablets, gaming devices, etc.

4. Aerospace and military – high speed are always used in high-end devices. For example, radar, navigation systems and other equipment with high reliability requirements.

What is the 3H Rule in High Speed PCB Design?

The 3H rule is a guideline suggesting that signal traces should be spaced at least three times the height of the dielectric (3H) between the signal layer and the adjacent ground or reference layer. This helps minimize crosstalk and maintain signal integrity, particularly for high-speed digital signals with rise times of 1 ns or less. Key aspects include:

– Trace Spacing: Keeping traces apart by at least 3H reduces electromagnetic coupling and interference.

– Signal Integrity: Adequate spacing helps maintain clear signals in high-speed circuits.

– Effectiveness: This rule is especially beneficial for fast digital signals, reducing the risk of crosstalk and interference.

For instance, if the dielectric height between the signal layer and the reference layer is 0.2 mm, traces should be at least 0.6 mm apart to follow the 3H rule.

How to Design a High-Speed Board?

Designing a high-speed PCB involves several strategies to ensure effective signal transmission, power distribution, and minimal EMI. Here’s a step-by-step approach:

Component Placement and Layer Stack-Up

Place high-speed components to minimize signal paths and interference. Group related components to simplify routing. In addition, create a layer stack-up that supports controlled impedance and reduces signal loss. Use ground planes between layers for a return path for high-frequency currents.

Trace Routing and Impedance Control

Keep high-speed traces short and direct, avoiding right-angle bends. Use microstrip or stripline configurations for controlled impedance and minimal noise. For impedance control, calculate and ensure consistent impedance for traces. Use differential pair routing for high-speed signals to reduce EMI and crosstalk.

Power Distribution and EMI Mitigation

Use decoupling capacitors near high-speed components to filter noise and stabilize the power supply. Design a robust power distribution network to minimize impedance and ensure stable voltage. And employ proper grounding and shielding techniques. Route high-speed signals on inner layers between ground planes to reduce EMI and provide a consistent return path.

Simulation and Testing

Use signal integrity analysis tools like SI or PI to simulate the PCB layout, predicting signal behavior and identifying potential issues. Analyze aspects like eye diagrams to assess signal quality.

High-speed PCB design is a complex but rewarding endeavor that ensures your electronics perform efficiently in high-frequency environments. By understanding the fundamentals and applying the right techniques and materials, you can create robust, high-speed boards. EBest Circuit (Best Technology) is here to assist you with expert advice and solutions for your high-speed PCB needs.

Network Switching Differential Pair Design Guide

Each TrxP/TrxN signal group (where xcx0-3) shall be routed as a differential pair. This includes the entire length of wiring processing.
The individual differential correspondences are packed together as tightly as possible. Impedance calculations are usually started by selecting the smallest line blank (4-5mil). The tracking width is then adjusted to achieve the necessary impedance.
Differential line group resistance of Ethernet is calculated at 100 ohms.
In general, when routing the four differential pairs of the Gigabit Ethernet to the r45 connector, at least one pair will pass through to the opposite outer layer.
Priority should be given to differential pair wiring. Terminals should be added after the routing is determined
The values of all resistance terminals in the Ethernet front end should be 1.0% tolerance
All capacitor termination Ethernet front ends in the module should have strict tolerances and high quality product media (npo)

Industrial PCB Design Considerations

Control the length of the circuit: Minimize the length of the circuit, especially the key signal lines, to reduce signal attenuation and delay.

Avoid sharp angles and right angles: Right angles and sharp angles should be avoided when wiring, and rounded or 45 degree angles should be used as far as possible to reduce signal reflection and impedance discontinuity.

Line width: Determine the line width according to the current size and thermal requirements to ensure the reliability and stability of the circuit.

Inter-layer wiring: Rational use of multi-layer PCB inter-layer wiring, such as the signal line on the inner layer, power and ground wire on the outer layer.

Impedance control: For high-speed signals, it is necessary to control the line impedance to ensure signal integrity, and carry out impedance matching design if necessary.

Avoid cross and parallel wiring: Try to avoid cross and parallel wiring of signal lines to reduce crosstalk and electromagnetic interference.
