With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
As shown in figure 1, a kind of raising packaging plastic the pattern-sealing property test accuracy provided for one embodiment of the invention
Method, encapsulation glue pattern here is used to be packaged viewing area, and this method includes：
Step 201, when making motherboard to be tested, formed and sealed for being pointed to the source and drain lead of welding disking area
Sealing glue pattern, the substrate and cover plate of the sealing glue pattern and the motherboard are collectively forming close for being carried out to source and drain lead
The annular seal space of envelope；
Step 202, when the cover plate to motherboard to be tested is cut, the cover plate of sealing cavity region is retained.
The test plate (panel) to be measured that method by the present invention is obtained is put into after hot and humid environment, due to the source of welding disking area
Leakage lead is sealed by annular seal space, and source and drain lead can be avoided to be corroded, and then avoids the envelope caused by the corrosion of source and drain lead
The interference that disturbing factor produced by filling the corrosion of glue pattern is tested pattern-sealing property of packaging plastic, it is possible to increase encapsulation glue pattern
The accuracy of performing leak test.
In above-mentioned step 201, the process for making motherboard to be tested may be referred to prior art, with prior art not
With before cover plate is covered on substrate, being formed is used to carry out source and drain lead sealedly sealing glue pattern.So exist
After cover plate is covered on substrate, sealing glue pattern is formed together with cover plate carries out sealed annular seal space to source and drain lead.
In the specific implementation, the concrete shape of the sealing glue pattern 4 formed may be referred to Fig. 3, the figure of the fluid sealant
Shape is annular, is centered around the periphery of source and drain lead 4.In addition, in order to further improve sealing effectiveness, fluid sealant figure can also be set
