Problems solved by technology

At present, the high-temperature marking materials with electrostatic discharge function used in my country are almost entirely dependent on imported products such as BRADY, Polyonics, and 3M from the United States, which seriously restricts the development of the domestic electronic assembly manufacturing industry.

Abstract

The invention relates to an electrostatic prevention temperature-resistant marking material which is mainly applied to tracing marking materials of integrated circuit surface mounting and chip encapsulation information, belonging to the technical fields of electronic and information application. The marking material of the invention takes a polyimide film (PI) as a substrate, electrostatic prevention permanent pressure-sensitive adhesive as a primer, special ink as a coating, and Glassine release paper as base paper. The manufacturing method of the invention comprises the following steps: firstly, carrying out surface electrostatic elimination treatment on the substrate; then coating the ink layer on one side of the substrate; then coating the primer on the Glassine base paper; and finally, compounding the glue surface of the Glassine base paper with the other side of the substrate to obtain the electrostatic prevention marking material (figure 1 and figure 2). The marking material comprises the following technical quality indexes: the temperature-resistant range of the material is -20 DEG C-320 DEG C (270 DEG C / 10min, 320 DEG C / 10S), the surface resistivity of adhesive is 104-108ohsm / sq, the sticky consistency is greater than or equal to 1000g, and the electrostatic discharge speed (time required for electrostatic discharge to 1%) is less than or equal to 0.01s; and the marking material resists certain acid, alkali, soldering flux and part organic solvents, is suitable for resin ribbon thermal transfer and UV ink printing, and is especially suitable for two-dimensional code marking, great application to chip encapsulation or special electrostatic discharge situations.
