Polyimide tape is a core material in electronic component protection. It has become an essential consumable in high-end manufacturing industries such as PCB board production and chip packaging due to its excellent high-temperature resistance and insulation properties.
Polyimide tape is a special tape designed specifically for protecting the conductive contacts of electronic components (commonly known as "Kapton Tape"), made of PET substrate coated with acrylic/silicone adhesive. Its core functions include:
Prevent oxidation contamination of PCB gold fingers
Resist high temperatures of wave soldering/reflow soldering (withstand 260°C)
Ensure safe insulation of circuit contact points
Core application scenarios of polyimide tape
PCB board production: protect the integrity of gold fingers in the welding process
Chip packaging: Prevent metal debris contamination during wafer cutting
LCD module assembly: shield electrostatic damage to driver IC contacts
Automotive electronics: meet extreme environmental requirements of high temperature and high humidity
With the miniaturization of 5G communication equipment, the demand for ultra-thin (≤0.05mm) polyimide tape has surged, and the market share of silicone products resistant to 300°C has increased by 18.7% annually
As a key auxiliary material in the electronics manufacturing industry chain, the technological innovation of polyimide tape directly affects the yield rate of terminal products. Choosing suppliers that have passed the IATF 16949 system certification and establishing a long-term and stable quality control mechanism has become the standard configuration of leading companies.
