CN103412418A - LCM reworking method - Google Patents

Abstract

The invention relates to an LCM reworking method which can overcome defects caused by the factors of material supply and manufacturing procedures. In the process of LCM production, defects can be caused in all the procedures of cleaning, ACF attachment, COG pre-pressing and main pressing, FOG pre-pressing and main pressing, adhesive dispensing and electrical logging due to the factors of the material supply and operation; by carrying out microscopic analysis on the factors causing the defects and adopting the reasonable reworking method, the reworking yield can be improved to more than 70%, and LCM production cost can be reduced.

Description

A kind of method of LCM heavy industry

Technical field

The present invention relates to a kind of method of heavy industry, be specifically related to a kind of method of LCM heavy industry.

Background technology

Along with popularizing of lcd technology, the processing profit of LCM is more and more less, the processing charges of small size LCM are reduced to every cun 1 yuan of left and right by every cun 3 yuan, therefore the lifting of yield is the task of top priority, and the enforcement of heavy industry is to improve one of effective means of yield, but the rework method of existing LCM all adopts single separation method to carry out heavy industry, simultaneously after heavy industry, the yields of LCM is low, thus the minimizing strengthened the processing profit of LCM.

Summary of the invention

The object of the present invention is to provide a kind of method of LCM heavy industry, can effectively improve the yields of described LCM heavy industry.

For achieving the above object, the method for described LCM heavy industry comprises the following steps:

1) LCM is placed and to detect under the microscope, check that whether described LCM damages because of the ITO short circuit of the screen lead district of LCM;

2) when described LCM damages because of the ITO short circuit of the screen lead district of LCM, directly on the laser repairing machine, with laser, short circuit place is interrupted and gets final product;

3) when described LCM be not screen lead district ITO short circuit because of LCM while damaging, under the condition of constant temperature, push away the FPC of LCM, IC and screen separated with bakelite;

4) with dust-free cotton bud, dip in ACF removal liquid and smear the ACF on screen, with bakelite, remove the ACF on screen after immersion, what can shield reuses.

Compared with prior art, the present invention has following beneficial effect:

The method of LCM heavy industry of the present invention is classified by the LCM to bad, and adopt corresponding rework method to carry out the heavy industry processing according to the bad reason of described LCM, especially when LCM damages because of the screen lead district ITO short circuit of LCM, by on the laser repairing machine, with laser, short circuit place being interrupted and repairs, thereby effectively improved the yields of described LCM heavy industry, thereby effectively reduced the production cost of described LCM.

Embodiment

Below in conjunction with embodiment, the present invention is described in further detail, following embodiment is only be used to the present invention is described, but the practical range be not intended to limit the present invention.

For achieving the above object, the method for described LCM heavy industry comprises the following steps:

1) LCM is placed and to detect under the microscope, check that whether described LCM damages because of the ITO short circuit of the screen lead district of LCM;

2) when described LCM damages because of the ITO short circuit of the screen lead district of LCM, directly on the laser repairing machine, with laser, short circuit place is interrupted and gets final product;

3) when described LCM be not screen lead district ITO short circuit because of LCM while damaging, under the condition of constant temperature, push away the FPC of LCM, IC and screen separated with bakelite;

4) with dust-free cotton bud, dip in ACF removal liquid and smear the ACF on screen, with bakelite, remove the ACF on screen after immersion, what can shield reuses.

When the method for LCM heavy industry of the present invention is carried out heavy industry at the LCM to bad, can be according to described LCM whether because the ITO short circuit of the screen lead district of LCM damages, when described LCM damages because of the screen lead district ITO short circuit of LCM, directly by the laser repairing machine, repair, method by LCM heavy industry of the present invention can make the yields of heavy industry reach more than 70%, thereby reduces the production cost of described LCM.

Claims (1)

1. the method for a LCM heavy industry, is characterized in that, comprises the following steps:

1) LCM is placed and to detect under the microscope, check that whether described LCM damages because of the ITO short circuit of the screen lead district of LCM;

2) when described LCM damages because of the ITO short circuit of the screen lead district of LCM, directly on the laser repairing machine, with laser, short circuit place is interrupted and gets final product;

3) when described LCM be not screen lead district ITO short circuit because of LCM while damaging, under the condition of constant temperature, push away the FPC of LCM, IC and screen separated with bakelite;

4) with dust-free cotton bud, dip in ACF removal liquid and smear the ACF on screen, with bakelite, remove the ACF on screen after immersion, what can shield reuses.
