Description

Device for improving ACF (anisotropic conductive film) material tray

Technical Field

The utility model relates to the technical field of PCB production; in particular to an improved device for an ACF tray.

Background

ACF is an abbreviation of Anisotropic Conductive Film (iso Conductive Film), and is characterized in that the electrical conduction direction of the Z-axis and the resistance characteristics of the XY insulating plane have obvious differences. When the difference between the Z-axis conduction resistance value and the XY-plane insulation resistance value exceeds a certain ratio, it is called as good conduction anisotropy. Conduction principle: the conductive particles are used to connect the electrodes between the IC chip and the substrate to make them conductive, and at the same time, the conductive short circuit between two adjacent electrodes can be avoided, so as to achieve the purpose of conduction only in the Z-axis direction. The ACF attaching machine is divided into a semi-automatic machine and a full-automatic machine, wherein the semi-automatic machine needs manual matching to complete the process, and the full-automatic machine completes the process by equipment. For semi-automatic equipment, there are usually pre-taping machines, alignment equipment and home press equipment. However, only pre-placement machines and present presses are currently available. The full-automatic equipment is fully integrated from pre-sticking to local pressure.

However, in the prior art, the material tray used by the ACF chip mounter is often fixed, and when the ACF material tray is replaced by a larger material tray, the material tray cannot be used due to interference, so that an improved device for the ACF material tray is provided.
