Semiconductor adhesive | Tantalum capacitor adhesive application solutions

2024-08-22

Solid tantalum capacitors are one of the most popular surface mount capacitors in consumer electronics, automotive, aerospace and medical equipment. They are widely used due to their high performance and miniaturization. History of Tantalum Capacitors The concept of tantalum capacitors dates back to the 1950s, when Bell Labs invented the technology to develop a compact capacitor for transistors. The unique structure of tantalum capacitors utilizes sponge-like tantalum material to greatly increase the surface area, thereby providing a higher capacitance density than other technologies. This innovation greatly improved the miniaturization of electronic devices. Basic Structure of Tantalum Capacitors Tantalum capacitors are electrolytic capacitors, so they are polar, meaning that current can only flow from the positive electrode (anode) to the negative electrode (cathode). The core structure of a tantalum capacitor consists of three main parts: anode, dielectric, and cathode. Anode: Usually made of high-purity tantalum powder, it is pressed and sintered into a sponge-like structure, which greatly increases the effective surface area. In traditional designs, the anode is connected to the circuit through a tantalum wire. Dielectric: A layer of tantalum pentoxide (Ta2O5) is formed on the surface of the anode, which serves as a dielectric layer. Cathode: In traditional solid tantalum capacitors, the cathode material is manganese dioxide (MnO2), which is then coated with materials such as carbon and silver to establish an electrical connection to the circuit. Challenges and Solutions for Tantalum Capacitors These devices require tantalum capacitors to have high reliability, stability, and miniaturization, and to operate stably under high temperatures, harsh mechanical environments, and long-term working conditions. In order to ensure the structural integrity and electrical performance of tantalum capacitors during assembly and operation, the selection of growth barrier glue and die attach glue is critical. SIPA 8708 is a growth barrier adhesive specifically used inside tantalum…

Induction gate electromagnetic induction coil potting solution

2024-08-22

As the core component of modern intelligent access control system, induction gate is widely used in office buildings, residential areas, factories and transportation hubs. In order to ensure the long-term stable operation of the induction gate, especially in various complex environments such as high temperature, high humidity or frequent mechanical vibration, high-performance potting glue must be used for protection. The potting glue not only needs to have excellent waterproof, dustproof and corrosion resistance, but also needs to provide excellent electrical insulation and mechanical stress relief functions to extend the product life. Potting material requirements: Waterproof: The induction gate needs to be exposed to the outdoors and be affected by rain, moisture, etc. for a long time. Therefore, the potting glue needs to have a protection level of IP67 or higher to ensure that the electronic components are not corroded by moisture. Weather resistance: Adaptability to different environmental conditions, including high temperature, low temperature, UV rays, etc. The material must maintain stable performance in the temperature range of -40°C to +120°C. Electrical insulation: To ensure the safety of circuit components in long-term operation and avoid the risk of short circuit or electric shock, the electrical insulation should reach 10^14 Ω·cm. Mechanical properties: Good impact resistance and vibration resistance to ensure that the equipment will not be damaged under daily use and external impact. Environmental requirements: Materials must comply with environmental standards such as RoHS and REACH. Glue recommendation

Flood light housing bonding, aluminum substrate heat dissipation adhesive application solutions

2024-08-21

In modern lighting equipment, floodlights are widely used in architectural lighting, stage lighting, stadiums, industrial plants and other scenarios due to their high brightness, wide-angle coverage and efficient energy utilization. However, in actual application, floodlights face harsh environmental tests, such as high temperature, low temperature, humidity, strong ultraviolet radiation, etc. Therefore, choosing the right electronic adhesive becomes a key factor in ensuring the reliability and durability of floodlights. In the design and production of floodlights, bonding and heat dissipation are two crucial links. The stable bonding of the glass cover directly affects the sealing and safety of the floodlight, while the efficient heat dissipation of the aluminum substrate is related to the working stability and life of the lamp.
