Common Product Specifications

Product Manufacturing Process

The manufacturing process of high conductivity, heat-conductive double-sided adhesive tape involves several critical stages. Initially, a high-purity acrylic adhesive is prepared through polymerization, ensuring minimal impurities that could affect thermal and electrical performance. The adhesive is mixed with thermally conductive fillers, typically ceramic particles, under controlled conditions to maintain uniform distribution and avoid agglomeration.

Next, the adhesive mixture is coated onto a carrier substrate, such as a polyester film, using a precision coating machine. The coating thickness is meticulously controlled to meet the specified range. The coated film is then passed through an oven where it undergoes curing at elevated temperatures, enhancing the adhesive's bonding strength and thermal properties.

Post-curing, the adhesive tape is subjected to rigorous quality control tests, including thermal conductivity measurement, breakdown voltage testing, and peel strength evaluation. Only tapes that meet stringent quality standards proceed to the slitting and rewinding phase, where they are cut to the required widths and lengths before being packaged for distribution.

Product Application Scenarios

High conductivity, heat-conductive double-sided adhesive tapes are essential in various application scenarios, primarily in the electronics and electrical sectors. One major application is in LED lighting and displays, where the tape is used to bond heat sinks to LED chips, ensuring efficient thermal management and prolonging the life of the LEDs.

In power electronics, these tapes play a critical role in attaching heat sinks to microprocessors and other high-power semiconductors, reducing thermal resistance and enhancing performance. They are also widely used in automotive electronics to fix radiators on power supply circuit boards or vehicle control circuit boards, improving heat dissipation and system reliability.

Another application is in the SMT (Surface-Mount Technology) process, where the tape secures flexible circuit boards (FPC) to fixtures for printing, patching, and testing. Additionally, it can be used as insulating tape for cable wrapping and as a substitute for mechanical fastening methods like screws, providing a clean and efficient bonding solution.
