A fpc holding pressure head

Abstract

Disclosed is an FPC pressure-holding ram, comprising a ram main body, wherein the ram main body comprises a wedge-shaped tip portion (11) and a rectangular block-shaped body portion (12); the ram further comprises a heating frame (21), the heating frame (21) being in the shape of the Chinese character "凹", and the ram is located within the heating frame (21); and a heating rod (22) for heating the ram main body is disposed on the heating frame (21), with one end of the heating rod (22) bearing against the ram main body. By means of the arrangement of multiple air suction holes, three problems are solved a single step, that is to say, the problem that harmful gas diffuses into the air and harms the human body is solved, the problem of heat dissipation of nearby elements is solved, and the problem of solidification of a non-melting part is solved.

Description

technical field [0001] The invention relates to an FPC pressure maintaining pressure head. Background technique [0002] The so-called holding pressure refers to the process of binding FPC (flexible circuit board) on the LCD surface in the automatic production process of LCD, which needs to be held by a high-temperature pressure holding head. The traditional pressure-holding indenter used for this kind of pressure-holding is an ordinary solid head, and then the indenter is heated by heating, and then the FPC is pressure-holding. During the pressure holding process, it is often found that when the FPC made of solidified aerobic material is heated and held for pressure, three problems will occur. 1. Poor firmness. It is found in the research that due to the lack of air circulation in the pressure head part during the pressure holding, the non-melting parts will melt slightly during the pressure holding, resulting in a low yield rate. 2. Since the pressure head is very hot, t...

AI Technical Summary

Problems solved by technology

1. Poor firmness. It is found in the research that due to the lack of air circulation in the pressure head part during the pressure holding, the non-melting parts will melt slightly during the pressure holding, resulting in a low yield rate.

2. Since the pressure head is very hot, the air around it is also very hot when maintaining the pressure, resulting in more or less damage to other nearby components

3. The irritating gas is produced due to the melting of the material. Since the pressure keeping is done in the clean room, this situation will affect the health of the operators.
