The Three Most Commonly Used Ceramic Materials For Pcbs

Due to the properties of ceramics, ceramic PCBs can be placed in high-pressure or high-temperature environments, traditional PCB substrate materials may exhibit flaws in extreme conditions. In the article, we will discuss three common ceramic PCBs.

Metallized Ceramic PCB

The three most commonly used ceramic materials for PCB manufacturing are:

Alumina (Al2O3) – The mechanical strength, chemical stability, thermal conductivity, and electrical properties of Al2O3 is advantageous compared to other oxide ceramics. The abundance of a raw material makes alumina the most commonly used ceramic substrate material. Al2O3 ceramic PCBs are used in automobile sensor circuits, shock absorbers, and engines. The high thermal stability of Al2O3 ceramic PCBs improves the performance and thermal efficiency of the circuits used in automobiles.

Aluminum Nitride (AlN) – The high thermal conductivity and coefficient of expansion are two properties that make AlN noteworthy as a substrate material in the PCB industry. The thermal conductivity of AlN varies in the range of 170 W/mK to 220W/mK. The CTE of AlN ceramic matches with silicon semiconductor chips, which establishes a good bonding between the two, thus making their assembly reliable. AIN is used in sensor circuits in automobiles, as it can withstand extreme temperatures, corrosion, and vibration while providing efficient, accurate, and sensitive sensor signals.

Beryllium Oxide (BeO) – BeO is a ceramic PCB substrate material with a thermal conductivity around nine times that of Al2O3 and greater than metal aluminum. BeO showcases better chemical stability than AlN and high electrical isolation comparable with Al2O3e. BeO is used in applications where the PCB is subjected to high temperatures or in high-density PCBs facing space limitations to provide air or liquid cooling.

Pyrolytic Boron Nitride Plate For RF Vacuum Windows

Pyrolytic Boron Nitride (PBN) is a kind of advanced ceramic, Pyrolytic Boron Nitride PBN Disc and other pyrolytic boron nitride products are synthesized on the mold by chemical vapor deposition (CVD) process, with BCl3 and NH3 at high temperature and low pressure. PBN products are extremely pure, as the purity of gas material is easier to be controlled. Typically, PBN products have a total impurity of <100 ppm, which means the purity is no less than 99.99%. It is the ideal material for windows.
The leading manufacturers of vacuum microwave devices use alumina and beryllia ceramics as the main materials for the input-output window barriers. At present, aluminum nitride is considered a possible alternative to these traditional materials. Meanwhile, a well-known pyrolytic boron nitride (PBN) seems to be a material, which remains underestimated by the major part of ED developers.

Why We Choose Ceramic Igniters Instead Of Metal Cartridge Heaters?

As ceramic igniters are faster and hotter than metal cartridge heaters, so many customers would like to choose ceramic igniters instead of metal cartridge heaters

We have done the test to compare pellet igniters and metal cartridges heaters and found that while the ceramic igniter reaches 800°C within 40 s and maximum temperature of 1008°C after 100 s, a conventional metal cartridge heater only reaches 800°C after 3 min 40s and a maximum temperature of 830 after more than 4 min.

Ceramic igniters are 5.5 times faster than metal heaters and 175°C hotter. In addition, the life span of a ceramic igniter is more than 3 to 5 times longer than a metal igniter and can achieve more ignition cycles (more than 100000 cycles in the laboratory).

All in all, alumina ceramic igniters are definitively the best choice to ignite wood pellets or biomass. Besides that, it could also be used in gas heating systems, ovens, ranges, dryers, and more.

Other advantages are as below:

Low porosity
High operating temperature
Corrosion resistant
Long-lasting
Easy to install and retrofit

300W Ceramic Ignition For Wood Pellet Grills

Spending a valued time with our loved ones is always a wonderful thing in the world, around with a delicious meal or sitting by a warm stove, which makes this time more happiness.

No matter whether wood pellet grills or wood pellet stoves, a good igniter can save a lot of trouble. That is a huge advancement in igniter technology, The traditional metal igniter is the weak spot of pellet grills/smokers. After years of development, they have improved pit performance and durability by upgrading to the ceramic igniter.

Innovacera introduced the new updated ceramic igniter, which is more suitable to be used for 300W high power grills or stoves, heating faster and more durable.

Features:
In some conditions is shrouded by a stainless steel sleeve that heats up to 1,800ºF for rapid pellet ignition.
Hot Flash Ceramic Ignitor System is rated up to 100,000 cycles.
Easy to install and replace, by adjusting the igniter to the correct position of being flush, it’s closer to the pellets and can light them faster!

Ceramic Igniter Use For Pellet Burner

One special application area for Innovacera high-temperature ceramic igniter is in heating systems that use solid fuels such as wood pellets as an energy source. The challenge here is to ignite the biomass in a very short time while retaining very low emission values. This can be perfectly achieved by Innovacera’s hot surface ceramic igniter.

Ceramic hot surface igniter for pellet burners need only approx. 1/10 of the energy of that needed by hot air fans and ignition blowers. Their ignition capacity lies between 120 and 200 Watt. Depending on the positioning of the ignition element in the boiler, the ignition time of approx. 60 seconds is extremely short. This also means minimal emissions!

Igniting wood chips, firewood, coal bricks or other biomass (such as corn, etc.) is possible.

Ceramic Reflector For Cynosure Laser

Innovacera ceramic reflectors work particularly well in Ruby and Nd: YAG laser pumping chambers and can be a highly cost-effective alternative to metal-coated reflectors. They are also extensively used as reflectors in housings for high-intensity lamps.

ceramic reflector is used for Lamp-pumped Solid-state Lasers

Ceramic reflectors can be glazed both inside the cavity and the out surface using a highly reflective glaze that seals the ceramic against ingress of cooling fluids that may alter the refractive index, introduce impurities and reduce reflectance and efficiencies. Glaze can also act as a filter and our yellow glazed reflectors have been used successfully in certain applications. The visible yellow color is complementary to the spectral colors violet and indigo and effectively absorbs these wavelengths up to around 450 nm.
