About vacuum pumps:
Q: How is vacuum measured?
A: 1 standard atmosphere at standard conditions will support a column of mercury 760mm high. This is where the linear measurement in vacuum comes into play.760mm can be also measured in inch Hg (760mm = 29.92″) and microns (760,000 microns = 760 mm = 29.92″). Depending on what vacuum level you require, you will use a different unit of measure for the vacuum measurement. When measuring vacuum below 1 micron, we go to scientific notation (Example: 1 x 10-3 mm Hg)
Q: What is an Absolute vacuum gauge?
A: An absolute pressure gauge is 1 that will measure your vacuum system without regard to and independent of local barometric pressure. Many dial (Bourdon) gauges and electronic Transducers reference local barometric pressure as their base measurement. However, since these devices are calibrated at SEA LEVEL conditions, operation of these devices above sea level will cause an erroneous reading. Either the gauge/transducer must be recalibrated for the higher elevation use or an absolute pressure gauge would need to be used.
A Torr gauge is an absolute pressure gauge and operates on the principle of an altimeter. The Gauge case is evacuated by the vacuum from the process and exerts a negative pressure on a hermetically sealed capsule. The lowering of the pressure in the gauge case causes the capsule to expand thereby causing the gauge movement to turn the pointer. The Torr gauge is highly sensitive and accurate in the lower pressure regions (0-100 mm Hg).
Q: how to judge vacuum degree?
A: Atmospheric Pressure- is variable but is standardized at 760 Torr or 101.325 kPa.
Low Vacuum- also called rough vacuum, is a vacuum that can be achieved or measured by basic equipment such as a vacuum cleaner.
Medium Vacuum- is a vacuum that is typically achieved by a single pump, but the pressure is too low to measure with a mechanical manometer. It can be measured with a McLeod gauge, thermal gauge, or a capacitance gauge.
High Vacuum- is vacuum where the MFP of residual gasses is longer than the size of the chamber or of the object under test. High vacuum usually requires multistage pumping and ion gauge measurement. NASA has revealed that the vacuum level recorded on the moon was 1×10-9 Torr.
Ultra-High vacuum- requires baking the chamber to remove trace gasses and other special procedures. Most standards define ultra-high vacuum as pressures below 10-8 Torr.
Deep Space- is generally much emptier than any artificial vacuum. Perfect Vacuum – is an ideal state of no particles at all. It cannot be achieved in a laboratory, although there may be small volumes which, for a brief period, happen to have no particles of matter in them.
Q: what type of vacuum pump should I choose for my application:
A: There is no 1 vacuum pump that is best for all applications. However, there are some general guidelines to remember for your selection.
Oil Lubricated Rotary Pumps are used in applications requiring fairly deep vacuum (< 1 mmHg) and pumping relatively clean gases (Air/N2). Oil lubricated pumps are available in Single stage & Dual stage depending on what vacuum level you need. Additionally, all the oil lubricated pumps are available in Belt drive or Direct drive configurations. Belt drive is preferred in applications where pump longevity and durability is desired because of the low pump rpm (<700 rpm) and their high oil holding capacity which also guards against premature wear from oil breakdown. Direct drive pumps are preferred because of their low cost, compactness and portability.
Dry Vane pumps; are used when a pump is required that does not require lubricating oil because of the objection to oil vapor discharge from the pump and filling/disposal issues with oil. Rotary vane dry pumps however are capable of only maximum vacuum of approximately 25″ Hg and can only pump clean DRY air. Any presence of moisture in the gas being pumped can lead to the pump rusting because of the absence of lube oil.
Rotary Screw Dry Pumps are used in applications where a high vacuum is required (up to 0 .571 mm Hg) and the process gas is not compatible with lubricating oil in oil sealed rotary pumps. These pumps are fairly expensive and are used where a lubricated oil sealed pump or liquid ring pump is not desired. Pleasure email us for more details.
Liquid Ring Pumps are used in applications where the process gas may contain a sizable amount of condensable vapors (water, solvents, acids, etc.) that will react negatively with the lubricating oil in Rotary Vane pumps, thereby causing pump damage. Being that a liquid ring pump is a centrifugal unit, the sealing medium can be water, oil or any other fluid compatible with the process. Liquid ring pumps are relatively inexpensive and can use any sealing fluid (water, oil, ethylene glycol, solvents, etc.) that is compatible with the process.
Q:what is gas ballast on vacuum pumps?
A: A gas ballast is a regulated in-bleed of a dry gas (usually Air/Nitrogen) into the compression portion of the pumping cycle of the vacuum pump. The gas acts as a stripping agent that will saturate with the contaminating vapors present in the pump and expelled out the discharge of the pump. Gas ballasts are usually installed as a standard component on all oil lubricated rotary vacuum pumps to aid in the removal of condensable vapors from the vacuum pump oil.

How Are Vacuum Pumps Employed in the Production of Electronic Components?

Vacuum pumps play a crucial role in the production of electronic components. Here’s a detailed explanation:

The production of electronic components often requires controlled environments with low or no atmospheric pressure. Vacuum pumps are employed in various stages of the production process to create and maintain these vacuum conditions. Here are some key ways in which vacuum pumps are used in the production of electronic components:

1. Deposition Processes: Vacuum pumps are extensively used in deposition processes, such as physical vapor deposition (PVD) and chemical vapor deposition (CVD), which are commonly employed for thin film deposition on electronic components. These processes involve the deposition of materials onto substrates in a vacuum chamber. Vacuum pumps help create and maintain the necessary vacuum conditions required for precise and controlled deposition of the thin films.

2. Etching and Cleaning: Etching and cleaning processes are essential in the fabrication of electronic components. Vacuum pumps are used to create a vacuum environment in etching and cleaning chambers, where reactive gases or plasmas are employed to remove unwanted materials or residues from the surfaces of the components. The vacuum pumps help evacuate the chamber and ensure the efficient removal of byproducts and waste gases.

3. Drying and Bake-out: Vacuum pumps are utilized in the drying and bake-out processes of electronic components. After wet processes, such as cleaning or wet etching, components need to be dried thoroughly. Vacuum pumps help create a vacuum environment that facilitates the removal of moisture or solvents from the components, ensuring their dryness before subsequent processing steps. Additionally, vacuum bake-out is employed to remove moisture or other contaminants trapped within the components’ materials or structures, enhancing their reliability and performance.

4. Encapsulation and Packaging: Vacuum pumps are involved in the encapsulation and packaging stages of electronic component production. These processes often require the use of vacuum-sealed packaging to protect the components from environmental factors such as moisture, dust, or oxidation. Vacuum pumps assist in evacuating the packaging materials, creating a vacuum-sealed environment that helps maintain the integrity and longevity of the electronic components.

5. Testing and Quality Control: Vacuum pumps are utilized in testing and quality control processes for electronic components. Some types of testing, such as hermeticity testing, require the creation of a vacuum environment for evaluating the sealing integrity of electronic packages. Vacuum pumps help evacuate the testing chambers, ensuring accurate and reliable test results.

6. Soldering and Brazing: Vacuum pumps play a role in soldering and brazing processes for joining electronic components and assemblies. Vacuum soldering is a technique used to achieve high-quality solder joints by removing air and reducing the risk of voids, flux residuals, or oxidation. Vacuum pumps assist in evacuating the soldering chambers, creating the required vacuum conditions for precise and reliable soldering or brazing.

7. Surface Treatment: Vacuum pumps are employed in surface treatment processes for electronic components. These processes include plasma cleaning, surface activation, or surface modification techniques. Vacuum pumps help create the necessary vacuum environment where plasma or reactive gases are used to treat the component surfaces, improving adhesion, promoting bonding, or altering surface properties.

It’s important to note that different types of vacuum pumps may be used in electronic component production, depending on the specific process requirements. Commonly used vacuum pump technologies include rotary vane pumps, turbo pumps, cryogenic pumps, and dry pumps.

In summary, vacuum pumps are essential in the production of electronic components, facilitating deposition processes, etching and cleaning operations, drying and bake-out stages, encapsulation and packaging, testing and quality control, soldering and brazing, as well as surface treatment. They enable the creation and maintenance of controlled vacuum environments, ensuring precise and reliable manufacturing processes for electronic components.

How Do Vacuum Pumps Assist in Freeze-Drying Processes?

Freeze-drying, also known as lyophilization, is a dehydration technique used in various industries, including pharmaceutical manufacturing. Vacuum pumps play a crucial role in facilitating freeze-drying processes. Here’s a detailed explanation:

During freeze-drying, vacuum pumps assist in the removal of water or solvents from pharmaceutical products while preserving their structure and integrity. The freeze-drying process involves three main stages: freezing, primary drying (sublimation), and secondary drying (desorption).

1. Freezing: In the first stage, the pharmaceutical product is frozen to a solid state. Freezing is typically achieved by lowering the temperature of the product below its freezing point. The frozen product is then placed in a vacuum chamber.

2. Primary Drying (Sublimation): Once the product is frozen, the vacuum pump creates a low-pressure environment within the chamber. By reducing the pressure, the boiling point of water or solvents present in the frozen product is lowered, allowing them to transition directly from the solid phase to the vapor phase through a process called sublimation. Sublimation bypasses the liquid phase, preventing potential damage to the product’s structure.

The vacuum pump maintains a low-pressure environment by continuously removing the water vapor or solvent vapor generated during sublimation. The vapor is drawn out of the chamber, leaving behind the freeze-dried product. This process preserves the product’s original form, texture, and biological activity.

3. Secondary Drying (Desorption): After the majority of the water or solvents have been removed through sublimation, the freeze-dried product may still contain residual moisture or solvents. In the secondary drying stage, the vacuum pump continues to apply vacuum to the chamber, but at a higher temperature. The purpose of this stage is to remove the remaining moisture or solvents through evaporation.

The vacuum pump maintains the low-pressure environment, allowing the residual moisture or solvents to evaporate at a lower temperature than under atmospheric pressure. This prevents potential thermal degradation of the product. Secondary drying further enhances the stability and shelf life of the freeze-dried pharmaceutical product.

By creating and maintaining a low-pressure environment, vacuum pumps enable efficient and controlled sublimation and desorption during the freeze-drying process. They facilitate the removal of water or solvents while minimizing the potential damage to the product’s structure and preserving its quality. Vacuum pumps also contribute to the overall speed and efficiency of the freeze-drying process by continuously removing the vapor generated during sublimation and evaporation. The precise control provided by vacuum pumps ensures the production of stable and high-quality freeze-dried pharmaceutical products.
