High temperature tape is mainly used in the electronics industry. The temperature resistance is usually between 120 degrees and 260 degrees. It is often used for painting, baking leather processing, coating masking and fixing in the manufacturing process of electronic parts, printed circuit boards and high-temperature processing masks. High temperature tapes include KAPTON high-temperature tape; Teflon high temperature tape; high-temperature masking tape; PET green high temperature tape; high-temperature double-sided tape, etc.
1. High temperature resistant masking tape.
High temperature masking tape is mainly used for sealing, baking paint, spray painting, packaging and fixing, construction decoration and other industries, as well as spray shielding protection of high temperature baking paint such as plastics and metal parts.
2. Teflon high temperature tape.
Teflon high temperature adhesive tape can be widely used in packaging, thermoplastics, composite materials, heat sealing, electronic and electrical industries. If the fabric is reinforced with Teflon high temperature tape, it will have higher strength characteristics and can be used in industries such as sizing machines, thermoplastic mold release rollers, and so on.
3. Polyimide high temperature tape.
Polyimide high temperature tape is widely used for welding protection, high temperature insulation bundling of transformer coils; capacitor insulation materials, high temperature spray shielding protection of PCB gold fingers, and cell phone lithium battery manufacturing and bundling. Polyimide high temperature insulation tape is based on polyimide film and coated with high temperature resistant silica gel. It has extremely high temperature resistance and can be used to protect gold fingers during reflow soldering.
4. PET high temperature tape.
PET high temperature tape is mainly used for high temperature spray shielding protection and insulation of electronic products, automobile industry, coatings and other products, and there is no residual adhesive after production. At the same time, it can also be used in the production of fixed printed circuit boards, electronic parts, resistance capacitors, and household appliances, machinery, electronics and other industries that require high-temperature coating protection and high-temperature adhesion and fixation.

，纳米磁芯的应用领域。
纳米磁芯的噪声主要是电路干扰的来源，在很多电力电子设备中，必须采用各种滤波元件来降低噪声，磁粉芯作为差模电感的主要元件，在滤波器中起着关键作用. 为获得较好的滤波效果，要求磁粉芯材料具有以下性能特点：饱和磁感应强度高、恒磁导率特性宽、频率特性好、交直流叠加特性好、损耗低。针对上述要求，我们一直保持开发铁粉芯、缺口非晶合金铁芯、铁镍铝粉芯（MPP粉芯）等磁铁用软磁材料。这些材料在不同的应用条件下都发挥了各自的优势和优势。
目前，UP粉芯在高端市场占有主要份额，但由于纳米晶磁芯的粉芯制造工艺复杂，原材料价格高昂，导致粉芯价格居高不下，应用范围较广。近年来，铁基纳米晶磁芯由于价格低廉、制备工艺简单、性能优良等特点备受关注，对它们的研究相当活跃，有望取代部分使用UP粉芯并得到应用在高频领域。
The contamination of the connector of the fiber jumper is an important cause of network failure. The fiber end face of the connector is contaminated by dust, which will result in poor optical signal transmission quality. Generally, the main location for cleaning the optical fiber is at the connector ports at both ends. There are two main cleaning methods, one is dry cleaning, and the other is wet cleaning. Commonly used dry cleaning tools include cassette-type fiber optic cleaning boxes and one-touch cleaning pens, and wet cleaning tools include dust-free wipes and cleaning sticks.
1. Store the fiber jumper correctly..jpg)
No matter whether the optical fiber jumper is in use or not, do not bend or stretch it excessively. Some damages caused by bending are clearly visible. However, in some cases, the loss may not be easily judged, such as micro-deformation of optical fiber caused by ultra-low temperature, millimeter-level displacement caused by defects of buffer or jacket, poor installation or Other factors. Because this type of damage cannot be found directly, it is often overlooked and will cause greater problems in the long run. To avoid further losses, we should pay attention to the following points:
(1) Do not bend the fiber jumper beyond its minimum bending radius, especially in the narrow space of high-density fiber wiring.
(2) Use appropriate tools to redesign the fiber jumper path to protect the cables from damage, such as horizontal cable management racks.
(3) Do not bump the optical fiber connector, otherwise the end face may be worn, and the fragments will pierce the skin. Therefore, it is recommended to put a dust cap on the jumper at any time.
(4) If you need equipment to detect and identify faults, such as damage and full attenuation inside the fiber jumper, you can use an optical time domain reflectometer (OTDR) and a fiber microscope.
