How to protect mass spectrometry filament assembly?

The mass spectrometer filament, a critical component of analytical instruments, plays a pivotal role in generating an ion source within a high vacuum environment. The performance of this filament, often made from LaB6 Ceramics, directly impacts the sensitivity, resolution, and stability of the mass spectrometer. The LaB6 filament assembly, a type of filament assembly specifically designed for longevity and high performance, is essential for the reliable operation of mass spectrometry systems.

 

mass spectrometry filament assembly

 

Both ends of the LaB6 filament assembly are connected to a high-voltage power supply, creating an electric field that facilitates ionization in the vacuum. In this environment, the metal atoms within the LaB6 filament are ionized, producing positive ions and electrons. These ions are accelerated by the electric field and interact with the filament surface, causing further ionization through collisions with surface atoms. This process generates a continuous supply of ions, forming an ion cloud that, when influenced by a magnetic field, separates ions of different masses, thus enabling mass spectrum analysis.

 

Given that the filament is a consumable, it may degrade over time, necessitating replacement. To protect the LaB6 filament assembly and prolong its service life, it is crucial to consider several factors that can accelerate filament damage.

 

The influence of oxygen
A leak in the mass spectrometer can introduce oxygen into the vacuum chamber, which, when combined with the filament’s operation, can significantly speed up the degradation process. Oxygen not only affects the filament but can also prematurely age the electron multiplier. To prevent this, it is advisable to check for air leaks using an Air/Water Tune before taking samples. Common leak points include the transmission line nut or the vent valve. Applying acetone to suspected leak points can help identify leaks by observing an increase in the abundance of m/z=58 ions.

Effect of solvents
Solvents pose another significant threat to the longevity of the filament. Particularly during liquid injections, large volumes of solvent can enter the mass spectrometer, potentially burning out a filament in normal operation. To mitigate this, setting a solvent delay time can be an effective strategy to protect the filament assembly.

 

In addition to these protective measures, the choice of filament assembly material is also critical. Tungsten (W) filament assembly, for instance, is known for its robustness and resistance to wear in certain applications. However, for applications requiring high analytical performance and longevity, LaB6 filament assembly remains a superior choice.

 

INNOVACERA, with its extensive expertise in the production and manufacturing of filament assemblies, including LaB6 Ceramics filament assemblies, stands ready to assist with your analytical instruments components needs. Should you require a high-quality LaB6 filament assembly or have any inquiries regarding the protection and maintenance of your mass spectrometry filament assembly, please do not hesitate to get in touch with us.

Introduction of AMB Substrate Technology

AMB (Active Metal Brazing) is a method of sealing ceramics and metals developed on the basis of DBC technology.

 

Compared with traditional DBC substrates, ceramic substrates prepared by AMB process not only have higher thermal conductivity and better copper layer bonding, but also have advantages such as lower thermal resistance and higher reliability. In addition, because its processing process can be completed in one heating, it is easy to operate, has a short time cycle, good sealing performance and a wide range of applications for ceramics, so this process has developed rapidly at home and abroad and has become a commonly used method in electronic devices.

AMB Substrate

AMB process description

AMB is to add active elements to the brazing material, form a reaction layer on the ceramic surface through chemical reaction, improve the wettability of the brazing material on the ceramic surface, so that the ceramic and the metal can be directly brazed and sealed.

Usually, the active element content is between 2% and 8% with good activity. When the content of active elements is too high, the brittleness of the brazing material will increase, thereby reducing the strength of the sealing surface. When the content of active elements is too low, the wettability of the brazing material to the ceramic will decrease, making the sealing difficult to complete.

 

Three kinds of ceramic materials of AMB

The ceramic lining produced by AMB process is mainly used in power semiconductor modules as the substrate of silicon-based and carbide-based power chips. At present, the mature AMB ceramic substrates are mainly: alumina, aluminum nitride and silicon nitride substrates.

 

At present, Al2O3 copper-clad ceramic substrates are mainly used in low-power heat dissipation devices such as LEDs, AlN and Si3N4 copper-clad ceramic substrates are mainly used in high-power IGBT modules such as high-speed rail and wind power generation.

Active Metal Brazing Substrate

1. Al2O3 ceramic substrate

Al2O3 ceramics are widely available and have the lowest cost. They are the most cost-effective AMB ceramic substrates with the most mature process. They have excellent characteristics such as high strength, high hardness, high temperature resistance, corrosion resistance, wear resistance and good insulation performance.

 

However, due to the low thermal conductivity and limited heat dissipation capacity of alumina ceramics, AMB alumina substrates are mostly used in fields with low power density and no strict requirements on reliability.

 

2. AlN ceramic substrate

AlN ceramic has better properties than traditional Al2O3 and BeO substrate materials due to its high thermal conductivity (theoretical thermal conductivity 319 W/(m·K)), low dielectric constant, thermal expansion coefficient matching that of single crystal silicon, and good electrical insulation performance, making it an ideal material for circuit substrate packaging in the microelectronics industry.

 

At present, aluminum nitride ceramic substrates (AMB-AlN) using the AMB process are mainly used in high-voltage and high-current power semiconductors such as high-speed rail, high-voltage converters, and DC power transmission. However, due to its relatively low mechanical strength, the high and low temperature cycle impact life of AMB-AlN copper-clad substrates is limited, which limits its application range.

 

3. Si3N4 ceramic substrate

AMB-SiN ceramic substrates have high thermal conductivity (>90W/(m·K)), thick copper layer (up to 800μm), and high heat capacity and heat transfer. In particular, when a thicker copper layer is welded to a relatively thin AMB-SiN ceramic, it has a higher current carrying capacity and better heat transfer.

 

In addition, the thermal expansion coefficient of AMB-SiN ceramic substrate (2.4ppm/K) is close to that of SiC chip (4ppm/K), which has good thermal matching and is suitable for reliable packaging of bare chips.

 

At present, AMB-SiN ceramic substrate is the preferred substrate material for application scenarios such as new energy vehicles, photovoltaic inverters, wind turbines and high-voltage DC transmission devices that require high reliability, high heat dissipation and partial discharge.

 

According to statistics, the ceramic substrates used for power semiconductors above 600V are mainly DBC and AMB processes, among which AMB silicon nitride substrates are mainly used for electric vehicle (EV) and hybrid vehicle (HV) power semiconductors, and AMB aluminum nitride substrates are mainly used for high-voltage and high-current power semiconductors such as high-speed rail, high-voltage converters, and DC power transmission.

 

Conclusion
The market demand for AMB ceramic substrates has increased, among which the rapid growth of electric vehicles, the accelerated installation of SiC, and the rapid growth of new energy vehicles are the main driving factors.

How does a PBN heater work? What is the insulation material?

  1. What is a PBN heater?

PBN material refers to pyrolytic boron nitride material obtained by CVD high-temperature deposition. BN refers to cubic boron nitride, which is obtained by hot pressing.

The common thickness of PBN parts is less than or equal to 3mm due to the different acquisition processes.

PBN heater refers to a graphite heater formed by depositing a thin layer of graphite on a PBN substrate and forming a graphite band by machining (laser engraving).

Finally, the graphite layer is covered with a layer of PBN cover layer (exposed electrode part) to become a complete graphite heater.

 

  1. How many ways are there to process?

Generally, there are two ways:

1st: PBN sheet to make a good groove, and then coated with pyrolytic graphite, add a layer of PBN coating (outside the circuit engraved by the pbn disk, deposition of pyrolytic graphite on the circuit, and then a layer of pbn deposited on the surface of the pg), the thickness of about mm, voltage and current, and then a layer of graphite.

Thickness of about 3mm or so, voltage and current according to the customer, but it should be low voltage and high current, fast heating.

2nd: graphite good trough, then trough on both sides coated with PBN, but graphite as a heating device, through the alternating current heating, will produce magnetic resonance, PBN coating is easy to fall off, so do not recommend this way of production.

So this way of production is not recommended, generally according to the first way.

 

Therefore, it can be seen that the substrate and the insulating covering layer are PBN, and the heat generator is graphite tape.

 

  1. Why is it manufactured in this way?

Graphite or pyrolytic graphite surface-wrapped coating, graphite is widely used in the heating field, but graphite in the vacuum and high-temperature conditions will continue to precipitate impurities, which will contaminate the ultrapure materials, the use of boron nitride non-porous, low coefficient of thermal expansion of the advantages of the graphite outer layer coated with PBN, so that the impurities precipitated by the graphite can be blocked, to protect the ultrapure materials are not contaminated. The graphite after coating is heated many times, and the surface layer of boron nitride is not easy to peel off.

 

  1. Advantage:

PBN heating pad has the advantages of chemical stability, corrosion resistance, etc., generally the highest sample heating temperature of about 1200 ℃, can work in E-5mbar oxygen atmosphere.

When working, you need to pay attention to avoid large rapid temperature rises and falls caused by the PBN cover layer and graphite layer detachment, but also pay attention to ensure that the electrodes are in good electrical contact, to avoid overheating at the contact, and damage to the electrode.

 

  1. Summarize the performance characteristics:

-Maximum temperature in vacuum 1650℃

-Maximum temperature in air 300 ℃(No recommend)

-High vacuum, extra high pressure, corrosive environment

-Very fast ramp rate, very low mass

-Very inert

-PG elements are encapsulated in PBN and are completely unaffected by deposition products

-Samples can be placed directly on the heated ceramic element plate

-Sizes up to 4″ square or round
