Since the LCD panel industry has become more competitive, therefore, moving the LCD modules to China, India and Eastern Europe has been the trend in the world, but to transport the LCM end semi-finished products to the LCD end and how to meet the cost and 100% yield has become a rather important and difficult task, moreover, the large size as the mainstream in the future, thus the automated packaging has become the mainstream of the future. In order to meet the above requirements, the current panel industry are all using Densepack method, through more than a year of experience, all panel factory, no matter the Japanese, South Korean and Taiwanese must face how to automate, how not to damage the polarizing plate, how not to damage the LCD glass and how to prevent the terminal area from oxidation and scratches, etc., a series of technical challenges.
In fact, to completely solve these series of problems, the main cause of the above problems must be analyzed one by one, in analyzing the main cause, following are the three major factors:
1. Machinery Automation.
2. BO BOX flatness and ventilation holes and strength and deformation rate.
According to the research conducted by the Company and the photoelectric factory for up to one and a half years, through the computer software simulation analysis and the test performed by the National Chung-Shan Institute of Science and Technology, actual object testing in the customer's factory, and the production research and development invested by the Company, finally succeeded in overcoming the currently deeply troubled packaging and transportation bottlenecks facing the panel industry. Summarized as follows: First, PP BOX will use 15 times foaming, flatness is controlled between -0 / +2 mm, and to prevent the ventilation hole from damaging the panel.
2. SPACER must conform to the following specifications:
A. Ra surface roughness is between 19 ~ 23μm.
A-1 Less than 19μm: cannot be pumped vacuum and packaged automatically.
A-2 More than 23μm: will damage the polarizing plate.
B. Number of surface emboss is at 15-18 grid per 1 cm2 square.
B-1 Number of emboss is less than 15: will cause vacuum attachment.
B-2 Number of emboss is more than 18: will cause puncture damage to the product.
C. Materials must use PP not PE, since PE material will absorb moisture and cause deformation that corrode the terminals and deform the liquid crystal compression.
D. The surface cannot have any foreign objects and impurities.
E. Bending of all four corners must be less than 3mm to prevent deformation and crush damages.
F. All four corners must have a guiding angle of 3 ° ~ 5 ° to prevent puncture damages.
G. Anti-static value needs to be between 108Ω ~ 1010Ω, to prevent electrostatic adsorption and electrostatic shock.
H. Do not have burrs and cut surfaces to prevent surface scratches.
I. Do not have foaming agents and heavy metals, sulfides and chlorides, etc.
The SPACER currently produced by the Company are produced completely in the Class 100,000 clean room, and 100% full inspection and use the most advanced electronic measuring instruments CCD and roughness tester, etc., to achieve three layers of QC, to allow the SPACER produced by our Company to achieve true 100% yield, and through SGS certification in compliance with RoHS and any environmental protection regulations, the most important is that currently the product has passed CMO, CPT, HannStar, AUO ... and other durability testing and use, to prove that the SPACER produced by the Company have the following characteristics :
1. Capable of fully automated packaging.
2. Will not damage the liquid crystal glass and polarizing plate.
3. Anti-static value will not reduce within a year.
4. The product will not deform with long time use.
5. Will not cause corrosion on the terminals.
6. 100% yield with three QCs + full inspection.
7. Recyclable re-use replacement, more environmentally friendly.
8. Price is more competitive.
