Problems solved by technology

The existing solder resist tape is formed by coating a pressure-sensitive layer on the substrate film layer. The tape substrate of this structure is a single-layer structure. This type of tape is used to adhere to the small holes of the printed circuit board as a shielding protection. And when the printed circuit board is sent to the wave soldering furnace, it is prone to shrinkage and shedding, which will cause the small holes on the printed circuit board to be exposed, resulting in the scrapping of the printed circuit board

Abstract

The invention discloses an anti-welding adhesive tape. The anti-welding adhesive tape comprises a base material film layer, a reinforcing belt and a pressure-sensitive layer and is characterized in that: the reinforcing belt is coated on the surface of one side of the base material film layer; and the pressure-sensitive layer is coated on the surface of the other side of the base material film layer. The base material film layer is combined with the reinforcing belt structure, so that the original single-layer base material structure is changed into a double-layer composite structure, and the anti-welding adhesive tape has ideal high temperature resistance, is not shrunk and deformed during use at high temperature, is soft and comfortable and has high tearability.

Description

Technical field [0001] The invention relates to the technical field of manufacturing and application of electronic products and their components, in particular to a solder mask tape. Background technique [0002] At present, in the object processing process of high-temperature engineering in the field of electronic product manufacturing, various tapes are needed to protect the shielding parts. For example, in the process of sending the printed circuit board into the tin furnace for wave soldering, it is necessary to use solder mask The small holes on the printed circuit board are blocked and protected. The existing solder mask tape is formed by coating a pressure-sensitive layer on a substrate film layer. The tape substrate of this structure has a single-layer structure. This type of tape is used to adhere to the small holes of the printed circuit board as a shielding protection. When the printed circuit board is sent to the tin furnace for wave soldering, it is prone to shrinka...
