| Strong impact resistance: The flat circular base structure is uniformly stressed and has excellent | |||||||||||||
| resistance to bending, vibration, and impact. It is not easy to crack, deform, or loosen electrodes under | |||||||||||||
| strong vibration conditions. | |||||||||||||
| Extremely strong environmental weather resistance: The ceramic substrate is resistant to acid and alkali, | |||||||||||||
| corrosion, oxidation, radiation, and has no risk of corrosion. It can work stably for a long time in | |||||||||||||
| various harsh environments such as humidity, salt spray, and chemical corrosion, and its service life far | |||||||||||||
| exceeds that of organic insulation materials such as epoxy and plastic. | |||||||||||||
| Strong thermal conductivity and heat dissipation ability: The thermal conductivity of 95 alumina ceramic | |||||||||||||
| is 10-20 times that of PBT, epoxy resin and other materials, which can quickly dissipate the heat | |||||||||||||
| generated by chip and contact operation, significantly reduce device temperature rise, improve power | |||||||||||||
| carrying capacity and overload tolerance, and extend device service life. | |||||||||||||
| Excellent electrical insulation performance: The alumina ceramic substrate itself has excellent | |||||||||||||
| insulation properties, stable performance under high frequency and high voltage conditions, can | |||||||||||||
| effectively isolate high and low potentials, and eliminate the hidden dangers of creepage and breakdown; | |||||||||||||
| The sleeve type structure can achieve full electrode insulation and more comprehensive protection effect. | |||||||||||||
| High bonding strength: The molybdenum manganese method forms a dense metal layer by coating molybdenum | |||||||||||||
| manganese alloy powder on the surface of ceramics and sintering at high temperature, which is firmly | |||||||||||||
| bonded to ceramics and has high tensile strength. | |||||||||||||
| Good solderability: The surface of the metallization layer can be plated with nickel, silver, etc., making | |||||||||||||
| it easy to solder and weld with metal pins or terminals such as copper and aluminum, achieving low contact | |||||||||||||
| resistance electrical connections. | |||||||||||||
|
High
temperature resistance and thermal shock performance: It can work under
extreme high temperatures, |
|||||||||||||
| and the thermal expansion coefficient of the metallization layer matches that of the ceramic, avoiding | |||||||||||||
| cracking or delamination caused by drastic temperature changes. | |||||||||||||
| Ultimate airtight sealing capability: After metallization, it can be brazed to metal parts to form a | |||||||||||||
| stable high vacuum or high-pressure sealing environment for a long time, without aging or leakage risks. | |||||||||||||
| The airtight service life far exceeds that of organic sealing materials. | |||||||||||||
| Strong resistance to chemical corrosion: stable to highly corrosive media such as acids, alkalis, and | |||||||||||||
| solvents, with a lifespan far exceeding that of metal parts. It is commonly used in corrosive working | |||||||||||||
| conditions such as chemical engineering, semiconductors, and new energy. | |||||||||||||
| High dielectric constant: Alumina ceramics have a high dielectric constant, which can achieve large | |||||||||||||
| capacitance values in a small volume and save space. | |||||||||||||
| Excellent chemical stability: resistant to strong acids and alkalis, oxidation, and aging; does not react | |||||||||||||
| with most media, maintaining performance without significant degradation in harsh environments such as | |||||||||||||
| humidity and corrosion. | |||||||||||||
| Dimensional stability: Aluminum oxide ceramics are inorganic rigid materials, without creep and plastic | |||||||||||||
| deformation problems of organic materials. They can maintain assembly accuracy under long-term high | |||||||||||||
| temperature and load conditions, ensuring long-term sealing airtightness and meeting the requirements of | |||||||||||||
| long service life. | |||||||||||||
