PET high-temperature tape is one of the accessories often used in many industrial industries and related high-temperature working environments. It is not only used in various electronics, industrial and other industries, but also in other fields, the use of high-temperature resistant tape is also very common.
In the fast-growing electronics manufacturing industry, PCB (printed circuit board) is the core component of electronic products, and its production quality directly affects the performance and reliability of the entire electronic product. In the production process of PCB boards, PET high-temperature resistant tapes play an indispensable role due to their unique properties.
1. The basic characteristics of PET high-temperature resistant tape
PET high-temperature resistant tape is a high-temperature resistant tape based on polyester film, which has excellent high-temperature resistance, electrical insulation, chemical stability and good mechanical strength. It can maintain stable viscosity and strength for a long time in a high-temperature environment, and at the same time has good chemical resistance, and can withstand the attack of acids, alkalis, greases, solvents and other chemicals. These characteristics give PET high-temperature resistant tapes a unique advantage in the PCB production process.
2. Application of PET high-temperature resistant tape in PCB board production
1. Shielding and protection
In the production process of PCB boards, many process steps need to be carried out in a high-temperature environment, such as soldering, spraying, etc. During these processes, high temperatures can cause damage to the components on the PCB. In this case, PET high-temperature adhesive is used.

The belt shields the area that needs to be protected, which can effectively prevent the erosion of components by high temperature and chemical substances, and ensure the production quality of PCB boards.
In addition, various chemical solvents are often used in the processing of PCB boards. These solvents may cause corrosion or damage to the PCB board. The PET high-temperature resistant tape has excellent chemical resistance, which can effectively prevent the erosion of the PCB board by these solvents.

2. Fixed effect
In the production process of PCB boards, various components need to be precisely fixed. Whereas, PET high-temperature resistant tape has excellent adhesion and can firmly bond various materials, such as metal, plastic, paper, etc. This makes PET high-temperature tape an ideal fixing material in the PCB production process. By using PET high-temperature adhesive tape to fix the components, it can ensure that the components will not move or fall off during processing, so as to ensure the production accuracy and quality of PCB boards.
3. Insulation
In the manufacturing process of electronic products, electrical insulation is a very important performance requirement. And PET high-temperature resistant tape has excellent electrical insulation properties, which can provide reliable electrical insulation protection during the production process of PCB boards. By insulating the critical areas on the PCB board with PET high-temperature resistant tape, problems such as short circuits and leakage between circuits can be prevented, and the electrical performance and safety of electronic products can be guaranteed.
