Knowledge Base

Q

This article introduces the definition, characteristics, and application fields of PI polyimide tape. This material is based on high-performance polyimide film and has excellent properties such as high temperature resistance and electrical insulation. It is widely used in electronic and aerospace fields and is one of the indispensable materials in modern industry. #PI polyimide tape ##1、 What is PI

Q

1、 Surface cleaning and decontamination Removing organic pollutants The surface of PI is prone to adsorbing organic substances such as grease, fingerprints, and release agents. It needs to be wiped with organic solvents (such as acetone and isopropanol) or specialized cleaning agents to ensure that there are no residues on the surface. After cleaning, it is necessary to blow or dry with dry nitrogen to avoid moisture affecting the subsequent treatment effect. Remove inorganic impurities By ultrasonic cleaning or plasma cleaning
