Anisotropic conductive adhesive attaching stage device and anisotropic conductive adhesive attaching method

Abstract

The invention discloses an anisotropic conductive adhesive attachment carrier device and an anisotropic conductive adhesive attachment method. The device comprises a carrier body. A plurality of areas where flexible circuit boards are to be placed are arranged on the carrier body. At least one lifting baffle corresponding to the areas where flexible circuit boards are to be placed is arranged on the carrier body. The lifting baffles are flush with the set edges of the areas where flexible circuit boards are to be placed. The lifting baffles extend out of the upper surface of the carrier body before the flexible circuit boards are aligned. The lifting baffles retract to the upper surface of the carrier body after the flexible circuit boards are aligned. The lifting baffles are designed on a vacuum adsorption carrier, the FPCs can be directly supported by the lateral sides of the baffles to be aligned without being corrected through human eyes for a long time, the problem of the alignment accuracy of AFC can be effectively solved, and the overall ACF attachment speed can be effectively increased. The anisotropic conductive adhesive attachment carrier device and the anisotropic conductive adhesive attachment method are simple, practical, easy to operate, and capable of reducing raw material waste and saving cost.

Description

technical field [0001] The invention relates to an anisotropic conductive adhesive attaching stage device and an anisotropic conductive adhesive attaching method, belonging to the technical field of liquid crystal manufacturing. Background technique [0002] At present, Rework (heavy industry) FPC (flexible circuit board, flexible circuit board) is to attach anisotropic conductive film (Anisotropic Conductive Film, referred to as ACF) on the FPC on the vacuum stage, and then attach the FPC with ACF Bonding (bonding) crimping with the Panel (LCD panel), the ACF attaching machine used is a semi-automatic machine, and the alignment is performed manually, and the FPC is aligned to the Mark (mark) position with human eyes. Sometimes it is necessary to speed up the operation Speed, it is easy to deviate from the Mark position, the alignment accuracy is poor, it is easy to cause alignment deviation, and it takes a long time. If the FPC with ACF and NG is not checked during Bonding...
