Laser repairing machine LS85 for TV, IPS, TFT, LCD panel, bright line repairing

 

This machine is suitable for IPS, TFT, LCD panel, bright line repair, the maximum size of the panel for 85 inches. Repair bad phenomenon: bright spots, dark spots, off half line, vertical color line, vertical color black line, single vertical black line, double vertical line and so on.

The main purpose:

The electrical inspection in the optical inspection can only negatively identify the location of the pixel defect, and the purpose of the laser repair is to further hope that the defective part can be corrected so that the original screening is to discard the wasteful product , Repair into an acceptable product. To the current acceptable product standards, the first is absolutely no cable defects; Secondly, many products are “no bright spot guarantee”, so there can not be a pixel is always bright spots, but can accept a few degrees of dark spots. So the object of laser repair is based on line defects and highlights.

 

Laser repair method:

Fusing: In the presence of two layers of metal across each other, with the appropriate energy and wavelength of the laser, can be opened and welded together, so that the two are not connected to the formation of short-circuit electrodes. In the design to consider the size of the overlap area and its surrounding and other metal distance. In addition to single-layer metal wiring, with the appropriate energy and wavelength of the laser, the metal can be opened and cut off the original wiring. In the design of the need to consider the size of the width and its surrounding and other metal distance.
