Reliability research on DC/DC power modules is a multi-faceted topic that requires analysis from multiple perspectives such as module principles, applications, environmental factors, and failure modes.
The following is a brief research report summary designed to provide an in-depth understanding of this topic.
Introduction to DC/DC module reliability research
As a key component of power conversion, DC/DC power modules are widely used in various electronic equipment.
How Boost Converters Work (DC-DC Step-Up) – Electronics Intermediate 1
Due to their compact size, high efficiency and high reliability, DC/DC power modules have become the first choice for many applications. However, as the complexity of electronic equipment increases, the reliability problem of power modules becomes more and more prominent. Therefore, it is of great practical significance to study the reliability of DC/DC power modules.
DC/DC power module is a power supply that converts DC input voltage into DC output voltage. Its working principle mainly includes two processes: voltage conversion and current control. Voltage conversion is achieved through switching tubes and magnetic components (such as transformers and inductors), while current control is achieved through error amplifiers and feedback loops.
Factors affecting the reliability of DC/DC power modules
Component aging: Components in the power module, such as switching tubes, magnetic components and capacitors, will gradually age with time, affecting the reliability of the module.
Environmental factors: Environmental factors such as ambient temperature, humidity, vibration, and electromagnetic interference will also affect the reliability of the power module.
Load characteristics: The load characteristics of the power module, such as the size and change of the load current, also have an important impact on the reliability of the power module.
Design and manufacturing process: The design and manufacturing process of the power module also have a great impact on its reliability. Reasonable circuit design, high-quality components and strict manufacturing processes can improve the reliability of power modules.
Use and maintenance: Improper use and maintenance will also affect the reliability of the power module. For example, excessive use, lack of regular cleaning and maintenance, etc.
Methods to improve the reliability of DC/DC power modules
Choose high-quality components: Choosing high-quality components can effectively improve the reliability of the power module.
Optimize circuit design: Optimizing circuit design can improve the stability and efficiency of the power module, thereby reducing the failure rate.
Enhanced heat dissipation design: Enhanced heat dissipation design can prevent the power module from overheating, thereby reducing the aging rate of components.
Improve the level of manufacturing technology: Improving the level of manufacturing technology can reduce damage to components during the manufacturing process, thereby improving the reliability of the power module.
Implement regular maintenance: Regular inspection and maintenance of the power module can detect and solve potential problems in time, thus improving its reliability.
Choose a suitable application environment: Understanding and choosing a suitable application environment can prevent power module failures caused by environmental factors.
Properly select and use loads: Understanding and rationally selecting and using loads can prevent power module failures caused by load problems.
Enhance the maintainability of the power module: Considering the maintainability of the power module during the design stage can reduce troubleshooting and repair time during later use, thereby improving its reliability.
How to design DC/DC power module to improve its reliability
To improve the reliability of DC/DC power modules, you can start to consider it from the design stage. Here are some design tips:
Redundant design: In situations with high reliability requirements, even if the power module is damaged, the system cannot be powered off. At this time, redundant power supply can be used to improve system reliability. When one power module is damaged, the other module can continue to provide power.
Temperature Management: Properly arrange radiators, fans and other cooling devices to ensure that the module works within a suitable temperature range, which can reduce the failure rate.
Electromagnetic compatibility design: Ensure that the module has good anti-interference ability and avoid electromagnetic radiation and electromagnetic susceptibility interference. For example, the input and output ends of the module need to be filtered and isolated.
Voltage margin design: Set a reasonable margin for the operating voltage, and consider voltage fluctuations and ripple factors in module design to prevent power supply collapse.
Protection measures: Use overvoltage, overcurrent and overheating protection circuits to prevent the module from being damaged under extreme working conditions.
Unbalanced dual-channel power and voltage output design: For modules with unequal output power, there are two main design methods: one is to use transformer windings and use coupled inductors and low-voltage stabilizing circuits Perform secondary voltage stabilization method. The second is to use multiple secondary windings of the transformer to output two relatively independent voltages. Although method one can improve the stability of the circuit and ensure the accuracy of the output voltage, it will increase the loss of the circuit. If method 2 is adopted, since the feedback can only control one voltage, the accuracy of only one output voltage can be guaranteed. The voltage of the other voltage can only be pre-stabilized by the transformer and filter inductor, and the main output power will inevitably change greatly. It brings about large changes in the secondary voltage of the auxiliary circuit transformer, so the accuracy of the output voltage cannot be guaranteed. To this end, this design uses two outputs for independent control and feedback, so that the output voltage can be accurately controlled and the losses caused by secondary voltage stabilization can be reduced.
Derating design: When the power supply is fully loaded for a long time, its service life will be shortened. The derating design can effectively increase the service life of the power supply. The high-energy cubic ACDC module power supply is recommended to be used within the load range of 30%~80% for the best performance in all aspects.
Peripheral protection design: Reasonable design can protect the power module from the external environment. For example, appropriate filter circuits or capacitors can be added to reduce ripple noise or improve power supply stability.

A potentiometer is an adjustable electronic component widely used in electronic equipment. Base metal glass glaze resistor slurry is an important material in potentiometer manufacturing, and its performance directly affects the quality and stability of the potentiometer.
This article will introduce in detail the manufacturing method of base metal glass glaze resistor slurry for potentiometers, including raw material selection, batching, mixing, grinding, modulation, filtration, inspection and packaging.
Raw material selection
Base metal powder: Choose base metal powder with high purity, uniform particle size and stable resistivity, such as nickel, chromium, copper, etc. These metals have good electrical conductivity and stability and can meet the requirements of potentiometers.
Glass glaze: Glass glaze is an inorganic non-metallic material with high temperature stability, chemical stability and good insulation properties. To select a glass glaze suitable for potentiometers, it is required that its composition has good compatibility with the base metal powder and can form a dense resistive film during the sintering process.
Organic carrier: Organic carrier is an important component of resistor slurry, which plays the role of dispersing metal powder and glass glaze and adjusting the viscosity of the slurry. Choose organic carriers with moderate volatility and good environmental performance, such as terpineol, butyl carbitol, etc.
Ingredients
Base metal powder, glass glaze and organic carrier are mixed according to a certain proportion. The proportion of ingredients is adjusted according to the performance requirements and manufacturing process of the potentiometer.
Generally speaking, the higher the content of base metal powder, the lower the resistivity; the higher the content of glass glaze, the higher the resistivity.
mix
Put the prepared raw materials into the mixing equipment and mix them so that the base metal powder, glass glaze and organic carrier are fully and evenly mixed together. The mixing time and speed should be moderate to avoid agglomeration of metal powder and excessively large glass glaze particles.
Grind
The mixed slurry needs to be ground to reduce the particle size and improve the fineness and uniformity of the slurry. Grinding equipment can use ball mills, sand mills, etc. During the grinding process, the grinding time and the type and quantity of grinding media should be controlled to avoid excessive grinding that will lead to a decrease in slurry performance.
modulation
The ground slurry needs to be modulated to adjust the viscosity and fluidity of the slurry. Appropriate amounts of diluents, thickeners and other auxiliary materials can be added during the preparation process. The prepared slurry should have good brushability and adhesion to form a uniform resistance film on the potentiometer substrate.
filter
The prepared slurry needs to be filtered to remove impurities and particles. Filtration equipment can use wire mesh filters, filter cloth filters, etc. The filtered slurry should be clean and free of impurities to ensure the quality and stability of the potentiometer.
test
Conduct quality inspection on the filtered slurry, including appearance, viscosity, fineness, solid content, resistivity and other indicators. Only the slurry that has passed the inspection can be packaged and used. Unqualified slurry needs to readjust the proportion of ingredients or undergo other processing until it meets the quality requirements.
Package
The slurry that has passed the inspection should be packaged in containers with good sealing, corrosion resistance, non-toxic and odorless packaging materials. During the packaging process, long-term contact between the slurry and the air should be avoided to avoid volatilization of the organic carriers in the slurry causing performance changes. The packaged slurry should be marked with product name, batch number, production date and other information to facilitate traceability and management.
Summary and Outlook
This article introduces in detail the manufacturing method of base metal glass glaze resistor slurry for potentiometers, including the steps of raw material selection, batching, mixing, grinding, modulation, filtration, inspection and packaging. These steps are of great significance to ensure the quality and stability of the potentiometer.
In the future, with the advancement of science and technology and the development of the market, the performance requirements for base metal glass glaze resistor slurries used for potentiometers will become higher and higher, and the manufacturing methods will also be continuously optimized and improved.
By adopting new raw materials, optimizing process flow, improving automation and other measures, more efficient, environmentally friendly and more stable manufacturing of base metal glass glaze resistor slurries for potentiometers can be achieved.

What is a glass resistor?
Glass resistor is a fixed resistor, usually composed of a metal conductor and a layer of glass. The glass is evenly coated on the surface of the resistor core through special process technology to form a protective layer, so that the resistor has good insulation properties. The working principle of glass resistors is based on Ohm’s law, which states that at a certain voltage, the current is proportional to the resistance. When electricity flows through a glass resistor, the electrons experience resistance, creating heat. This power conversion can be expressed as P=VI or P=I²R. Glass resistors mainly play a role in limiting current in circuits. They can be designed to limit voltage, control current, and measure electrical signals. At the same time, due to its high temperature resistance, corrosion resistance, moisture resistance and other characteristics, glass resistors are often used as circuit regulators, power filters and test components of various instruments and equipment.
How does a glass resistor work?
The working principle of glass resistors is based on Ohm’s law, which states that at a certain voltage, the current is proportional to the resistance. When electricity flows through a glass resistor, the electrons experience resistance, creating heat. This power conversion can be expressed as P=VI or P=I²R. In a glass resistor, the glass acts as a medium to insulate and isolate, and the metal conductor acts as a resistor. When current passes through the metal conductor and the glass layer, the current is blocked due to resistance, causing the electrons in the metal conductor to slow down in the glass layer, thus producing resistance. The resistance value of a glass resistor will also vary due to the different resistivities of the metal conductors, as well as the thickness and uniformity of the glass layer. Therefore, by controlling parameters such as the material, shape and size of the metal conductor, as well as the thickness and uniformity of the glass layer, glass resistors with different resistance values can be produced.

Metallic glass glaze resistors have excellent heat resistance, stability, reliability, corrosion resistance, moisture resistance and other properties, so they are widely used in electronic equipment. It can be used in electronic equipment such as signal generators, oscillators, and amplifiers to accurately control current and voltage to ensure the stability and reliability of electronic equipment. According to different combinations of metal oxides and glass glazes, the resistance and accuracy of metal glass glaze resistors can also be adjusted and controlled differently. In short, metallic glass glaze resistor is an important electronic component with wide application prospects.

Replace the inductor: If the inductor is completely damaged or cannot be repaired, the best way is to replace it with a new inductor. Please note that if you know the model number of the inductor, you can buy it online and replace it yourself. If you are not sure about the model, it is best to consult a professional technician and ask them to replace it.
Welding repair: If the coil of the inductor is disconnected or has poor contact, you can consider using welding to repair it. Please note that proper solder and soldering temperature should be used when soldering to avoid damage to other components.
Winding the coil: If the coil of the inductor is damaged, consider re-winding the coil. Please note that proper wire diameter and number of turns should be used during winding to restore the electrical properties of the inductor.
Secure the core: If the inductor’s core becomes loose or falls off, consider using appropriate glue or fixtures to re-fix the core in the correct position.
It should be noted that for some complex chip inductors, the repair process may require professional techniques and tools.
Therefore, before carrying out repairs, it is best to consult professional technicians or relevant experts to understand the feasibility of repairs and choose appropriate repair methods.
At the same time, when repairing and maintaining any electronic equipment, you must pay attention to safety to avoid damage to the equipment and people.
If my chip inductor is overloaded, how should I check and repair it
If the chip inductor is overloaded, you first need to check whether the appearance of the inductor is burnt, discolored, cracked, etc., and whether there is any abnormal sound or smell. These signs may indicate that the inductor is damaged.
If the visual inspection reveals no problems, you can use a multimeter to check the resistance value of the inductor. The resistance value of a normal inductor should be close to zero. If the resistance value is very large or infinite, it may indicate that the inductor has been damaged.
If it is determined that the inductor is damaged, the cause of the damage needs to be found and corresponding repair measures must be taken. Common repair methods include replacing inductors, welding repairs, winding coils, and fixing cores. The specific repair method needs to be determined based on the degree of damage and the cause of the damage.
When repairing chip inductors, you need to pay attention to safety issues. When replacing inductors or soldering, problems such as short circuits or overheating need to be avoided to avoid damage to the circuit board and other components. At the same time, appropriate tools and materials, such as suitable soldering stations, soldering tin, solder paste, etc., need to be used to ensure the quality and reliability of the repair.
In addition, in order to prevent overloading of chip inductors, some preventive measures can be taken, such as controlling the stability of the power supply voltage, avoiding overloading of the power supply line, and selecting appropriate inductors and components. These measures can effectively reduce the possibility of inductor overload and improve the stability and reliability of the circuit.
How should the withstand voltage and current values of chip inductors be selected and optimized
When selecting and optimizing the withstand voltage and current values of chip inductors, the following aspects need to be considered:
Circuit requirements: Determine the required withstand voltage and current values based on the operating voltage and current of the circuit. If the working voltage of the circuit is high, you need to choose an inductor with a higher withstand voltage value; if the working current of the circuit is large, you need to choose an inductor with a larger current value.
Magnetic core material: Parameters such as magnetic permeability and saturation flux density of the magnetic core material will affect the performance of the inductor. Choosing a core material with high magnetic permeability and saturation flux density can improve the withstand voltage and current values of the inductor.
Coil wire: Parameters such as the cross-sectional area and resistance value of the coil wire will also affect the performance of the inductor. Choosing a coil wire with a larger cross-sectional area and smaller resistance value can increase the current value of the inductor.
Package size: Package size will affect the heat dissipation performance and mechanical strength of the inductor. When selecting the package size, heat dissipation needs and mechanical strength requirements need to be considered to ensure the performance and reliability of the inductor.
Working environment temperature: The working environment temperature of the inductor will affect its performance and reliability. When selecting an inductor, you need to consider the influence of the working environment temperature and select an inductor with corresponding temperature resistance.
In order to optimize the withstand voltage value and current value of the chip inductor, the following aspects can be considered:
Optimize the structure and size of the magnetic core: By optimizing the structure and size of the magnetic core, the withstand voltage and current values of the inductor can be further improved. For example, increasing the cross-sectional area of the magnetic core and reducing the number of turns of the coil can increase the current value.
Optimize the coil design: Optimizing the coil design can improve the performance and reliability of the inductor. For example, adopting appropriate winding methods and number of turns, selecting appropriate coil wire materials and other measures can improve the current value and voltage resistance value of the inductor.
Strengthen the heat dissipation design: Strengthening the heat dissipation design can improve the heat dissipation performance and stability of the inductor. For example, measures such as adding heat sinks and improving heat dissipation channels can improve the withstand voltage and current values of the inductor.
Use high-quality raw materials: Using high-quality raw materials can improve the performance and reliability of the inductor. For example, choosing core materials with high magnetic permeability and saturation magnetic flux density, selecting coil wires with low resistance values, and other measures can improve the withstand voltage and current values of the inductor.
To sum up, selecting and optimizing the voltage and current values of chip inductors requires comprehensive consideration of circuit requirements, core materials, coil wires, package size, working environment temperature, etc.
At the same time, during the manufacturing and use processes, quality control and process optimization are strengthened to ensure the quality and reliability of chip inductors.
What are the main factors of the temperature resistance of the patch
The temperature resistance of the patch inductor mainly depends on the following factors:
The quality of raw materials: High -quality raw materials have better stability and reliability, and can effectively extend the life of the inductance. For example, a magnetic core material with high magnetic guidance, low magnetic damage, and coil wires with high temperature resistance and low impedance.
Structural design: By optimizing the structural design of the inductance, the heat loss of the inductance can effectively reduce the heat loss of the inductance in high temperature, thereby improving the temperature resistance. For example, measures such as optimizing coil winding and increasing the cross -area of the coil can improve the thermal performance and reliability of the inductance.
Heating design: In order to prevent inductance from overheating in high temperature environments, the heat dissipation design of inductance needs to be strengthened. For example, increased heat dissipation pieces and selection of materials with good thermal conductivity can improve the heat dissipation performance and temperature resistance of inductance.
Production process: In the process of inductance, the production process must be strictly controlled to ensure the quality of the inductance, and the temperature resistance of temperature resistance is reduced due to the problem of production technology. For example, strictly control the winding process of the coil and the assembly process of magnetic cores.
In summary, the temperature resistance of improving the inductance of the patch needs to be started from choosing high -quality raw materials, optimizing structural design, strengthening heat dissipation design, and strict control of production technology.
At the same time, in practical applications, we should also pay attention to compliance with the use specifications and precautions to ensure that the temperature resistance of the patch is fully guaranteed.
