Why don’t use BeO as substrate to make DBC ceramic PCB?

Monday, June 22nd, 2020

It is widely known that BeO with high thermal conductivity (200-250W/m.k). High dielectric constant 6-7 (0.1MHz) and dielectric loss tangent is 10-4 (0.1GHz), extremely high working temprature. It is ideal material for ceramic PCB, lots of engineers want to use it as DBC ceramic PCB substrate.

But it is not popular in ceramic PCB market, comparing with Al2O3, AIN, Si3N4, or ZrO2, as the powder of BeO is extremely poisonous.

The poison gas is produced by the reaction between oxygen, Cu and BeO under 1065-1085 degrees Celsius, so it is limited to make cooper on BeO substrate, it has caused ALN (Aluminium Nitride) is becoming more and more popular.

Right now, only few countries are using BeO to make ceramic PCB, such as USA, Russia and China. USA had biggest capability to make BeO , and here in China, there’re still some companies to make BeO raw material and among them, a few companies to produce direct copper bonded (DCB) on BeO because of environment limitation.

Though BeO is not popular for DBC technology, but it is feasible for thick film technology, because when the mentalization of Ceramic PCB, the conductor (Au or AgPd) on BeO substrate was made by silk-screen printing, and drying temperature is only around 850C, no need to under high temperature environment, so there is no chemical reactions, no environment issue.

Below the thick film ceramic PCB manufacturing process for your reference.

Here is the photo of BeO with AgPd conductor.

Ceramic Multilayer PCBs: Advantages and Disadvantages

Monday, January 6th, 2020

The primary advantage of ceramic multilayer PCBs lies in their thermal properties. The most significant of these is thermal conductivity, which outperforms traditional materials by a tremendous margin. In the table below, the most used board material, FR4, is compared with the ceramic multilayer board in a number of important categories.

The Application of Ceramic PCB in Communication Industry

Wednesday, January 16th, 2019

Time goes by, the communication of human being still reforms constantly. We are surrounded by various of communication tools, including broadcasting, mobile phone, GPS etc.. And they have become an indispensable part in our daily life. The reason why they are able to serve for us is not only depend on the development of science, but also benefit from a kind of media–antenna. Antenna is the key to the communication. If there is a problem, the connection of signals will be lost.

The antenna can be used in various environments, so it is difficult to meet the requirements of itself. In order to ensure that the antenna can work normally, it is necessary to ensure its quality, whether in the selection of material or in the production process.

Ceramic PCB

Ceramic PCB

The common printed circuit board can not meet the performances of the antenna. Nowadays, the most suitable product is the ceramic PCB. The ceramic PCB possesses various benefits as following:

  1. The dielectric constant is small.
  2. Low loss in high frequency.
  3. Having good performance in signal transmission.
  4. High boding strength between metal layer and the substrate of the ceramic PCB.
  5. With good performance in insulation. It will appear high voltage during the antenna is working, but it is incredible dangerous for human being. The ceramic PCBhas nice performance in insulation and the resistance in breakdown voltage is up to 20KV/mm which is able to protect human safety effectively.
  6. It can be used in high density assembly. The line space resolution of the ceramic PCBis able to reach 20őľm, so that the lightness and thinness of the communication equipments can be realize.

Huawei Accelerating the ‚ÄúInternet of Vehicles‚ÄĚ Program Promotes Growth of PCB Market

Thursday, September 27th, 2018

Nowadays, vehicles have become the next hotspot for mobile device manufacturers. Google and Apple have already released their own vehicle intelligence system.

The Internet of Vehicles makes the cars get smarter and safer. At the same moment, connecting people to the car by big data transmission, then the real-time traffic, distance diagnosis and so on can be realized. Huawei will cover all of these fields in the future.

Since 2011, Huawei has begun to increase the investment in the field of Internet of Vehicles. Besides, it also released vehicle mobile hotspot, automotive online diagnostic system as well as 3G and 4G communication modules at the Mobile World Congress of Barcelona in 2013. What’s more, Huawei undertaking the eCall emergency project from some domestic Internet of Vehicles organizations.

In 2015, Huawei announced that cooperated with Volkswagen and would accelerate the ‚ÄúInternet of Vehicles‚ÄĚ program together.

All objects involved in the IoT (Internet of things), which require interaction and intelligent judgment function, demand a large number of sensors.

More than 100 sensors, including inertial sensors, pressure sensors, temperature sensors, and position sensors, have been installed in the recently launched advanced vehicles to achieve optimal control performance with highly electronic control, and to improve the safety, convenience and comfort of drivers. As we all know, it is necessary to widely apply the ceramic PCBs if the domestic sensor industry wants to keep continuous progress.

5G Will Drive the Development of PCB

Wednesday, September 19th, 2018

As the basic material of the digital products, PCB possesses a vast market. It can be applied to a variety of industries, including communications, computers, digital products and automobiles. Communications and computers account for the largest part.

5G era is around the corner, and China plans to achieve official commercialization of 5G network by 2020. The development of 5G puts higher requirements on the performance of PCB substrate, especially reflected in the followings:

1.      Low loss, high reliability

2.      High frequency

3.      High frequency PCB structure

4.      Low cost

HDI PCB

It is reported that 5G RF (radio frequency) will introduce Massive MIMO technology that requires communication with a wider spectrum and wider bandwidth in the millimeter wave band. Compared with the number of million-level base stations in the 4G era, the development of millimeter waves will promote the scale of base stations to exceed tens of millions in the 5G era.

It can be predicted that the full commercialization of 5G will push the construction and upgrading of the communication base stations. As a result, there will be a huge demand for high-frequency and high-speed PCB, and the PCB will meet the needs of a new round of upgrading and replacement.
