Abstract
The invention discloses the chipping method for quickly detecting after a kind of sapphire substrate sheet slice, the method is as follows: the sapphire substrate sheet after cutting successively being taken out and is put in wafer case in order;Wafer case is placed on binder, binder is shaken, the sapphire substrate sheet pingbian in wafer case is shaken to top;It is irradiated using strong light in wafer case oblique upper;Sapphire substrate sheet marginal portion is examined with the presence or absence of shining point, stops shaking binder after finding the part of shining point, flash portion is identified with marking pen;Continue to shake binder, until sapphire substrate sheet completes 360 ° of rotations in wafer case;It repeats the above steps;Sapphire substrate sheet with color identifier is taken out out of wafer case and completes checking procedure.The method increase the checkabilities after sapphire substrate sheet slice, have saved cost of human resources, have reduced fragment rate, the sliver rate of grinding process, improve the processing efficiency and product yield of grinding process.
Description
Technical field
The invention belongs to sapphire manufacture fields, and in particular to the chipping after a kind of sapphire substrate sheet slice is quickly examined
Method.
Background technique
Sapphire (Sapphire) crystal has excellent optical property, physical property and stable chemical property, extensively
Applied to high-brightness LED substrate material.Sapphire substrate sheet generallys use the method for diamond wire cutting sapphire crystal bar to prepare,
Due to the hard brittleness of sapphire material itself, after dicing during (especially cutting process exist broken string when), in indigo plant
Jewel substrate slice edge will form chipping defect, and the sapphire substrate sheet with chipping circulates to grinding process, grind
Process easily causes sliver, fragmentation.In the prior art, the inspection using artificial monolithic is examined in sapphire substrate sheet chipping after slice
Mode, it is low that there are working efficiencies, picks and places sapphire substrate sheet repeatedly, can collide during pick-and-place, generates new chipping and lacks
Fall into
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides the quick inspection party of chipping after a kind of sapphire substrate sheet slice
Method is changed to every 25 boxes by original monolithic inspection and tests, need not pick and place repeatedly Sapphire Substrate in checkout procedure
Piece avoids and generates new chipping defect, and the method increase the checkabilities after sapphire substrate sheet slice, has saved manpower
Resources costs reduce fragment rate, the sliver rate of grinding process, improve the processing efficiency and product yield of grinding process.
The present invention is achieved by the following technical solutions:
A kind of chipping method for quickly detecting after sapphire substrate sheet slice, comprising the following steps:
After step 1) diamond wire multi-line cutting machine cutting process automatic running, by the sapphire substrate sheet after cutting according to
Secondary taking-up is simultaneously put in wafer case in order;
Wafer case is placed on binder by step 2), binder is shaken, by the sapphire substrate sheet pingbian in wafer case
It shakes to top;
Step 3) is irradiated for 40~60 ° using strong light in wafer case oblique upper;
Step 4) shakes binder with the speed of 50~80 °/min;
Step 5) examines sapphire substrate sheet marginal portion with the presence or absence of shining point, stops after finding the part of shining point
Binder is only shaken, flash portion is identified with marking pen;
Step 6) continues to shake binder, until sapphire substrate sheet completes 360 ° of rotations in wafer case;
Step 7) is placed on binder after wafer case is overturn 180 °, repeats step 3) to step 6);
Step 8) takes out the sapphire substrate sheet with color identifier out of wafer case, which is that marginal portion is deposited
In the sapphire substrate sheet of chipping.
Preferably, it is 25 that the sapphire substrate sheet after the step 1) cutting, which puts the quantity in wafer case,.
Preferably, mobile phone or flashlight can be used in step 3) the strong light.
Beneficial effects of the present invention are as follows:
Chipping method for quickly detecting after sapphire substrate sheet slice of the invention, every 25 boxes are tested, are examined
Sapphire substrate sheet need not be picked and placed repeatedly in the process, avoid and generate new chipping defect, can quickly have edge
The sapphire substrate sheet of chipping is picked out, and the checkability after improving sapphire substrate sheet slice has saved human resources
Cost;Meanwhile the fragment rate of grinding process, sliver rate are reduced, improve the processing efficiency and product yield of grinding process.
Specific embodiment
Present invention is further elaborated in following combination specific embodiment.
