Field of the Invention The present invention relates to a method and a structure for fabricating a wafer grinding ring, and in particular, an innovative designer who applies a polishing process to the surface of the metal ring. [Prior Art] _ According to the manufacturing method of the conventional wafer grinding ring, a metal ring and a plastic ring are separately prepared, and the plastic ring is attached and fixed to one side of the metal ring, wherein the metal ring system only borrows It is formed by precision car processing. In order to increase the firmness of the bonding of the bonding surface, the industry usually applies sand blasting to the bonding surface of the metal ring to obtain a rough surface effect, thereby increasing the glue. The attachment area; however, the manufacturing method of the conventional wafer grinding ring has the following problems in practical application: After the bonding surface of the metal ring is subjected to sand blasting, the bonding surface is presented under the microscopic φ The unevenness state, together with the gel layer before it is hardened, is also an unstable structural type. The error caused by the plastic ring is such that the predetermined polishing surface flatness will appear after the plastic ring is completed and fixed. The value of the deflection error of the plastic ring is usually as high as 〇·2mm. However, after the wafer grinding ring is finished, the plastic is plastic. The polishing surface must have the best flatness to meet the expected grinding precision and effect. However, the conventional wafer grinding ring product has an excessive error value as mentioned above. To correct this error value, the current practice, When the wafer grinding ring is used for the first time on the machine, the 5 1275446 first grinding operation without workpieces is performed, that is, the grinding ring of the wafer is ground, and the direct working platform is subjected to contact wear until the polished surface is worn until After the flat state, the actual workpiece grinding operation can be performed; and if the pre-grinding operation is in the error state of the grinding surface, it usually takes 3 to 4 hours to complete, "It is conceivable that the grinding is apparently caused by grinding. The working hours are wasteful, and the grinding machine will increase the force of this pre-grinding operation: huge electric energy, mechanical wear and personnel costs (required to operate two members), which does not meet the better industrial utilization benefits. ▲ Moreover, the wafer grinding ring will also be subjected to the grinding operation for a long time due to the precautionary factors, so that the actual workpiece grinding operation has not yet been performed. 'That must be (4) 〇. 2mm (four) ring thickness, which can be used to the thickness of the plastic ring that is relatively shallow (note: the plastic ring can be used only 3~5mm grinding thickness), so obviously The problem of the wear of the plastic ring is accelerated, the service life is shortened, and the disadvantages are lacking. In view of the problems and shortcomings caused by the above-mentioned conventional method for manufacturing the wafer grinding ring, how to develop a precision of the wafer grinding ring into a mouth can be greatly improved. In order to reduce the cost of the industry's grinding and processing, the innovative design has to be considered by the relevant industry. In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After the design and careful evaluation, the invention is finally practical. [Abstract] ι27·5446 The main purpose of the present invention is to provide an art structure for the manufacture of a wafer grinding ring, which JL desires. i — Eight problems to be solved. The method for manufacturing the known wafer grinding ring is to attach the JL plastic lamp/type glue to the metal ring side. That is to say, the finished product '$ is formed, and the grinding surface of the plastic ring has too large precision precision, and it is necessary to carry out a long time without the workpiece pre-grinding operation, causing problems such as the length of the grinding time and the cost increase; In the method of the circular grinding ring, a metal ring and a plastic ring are separately prepared, and the plastic ring is attached and fixed to the side of the metal ring. The technical feature of the present invention is mainly based on the metal. The second side of the ring is further subjected to a grinding process, thereby achieving a better flatness of the polished surface of the plastic ring, thereby greatly reducing the number of wafer grinding rings, such as the use of the grinding surface. The error value of the precision and degree can be as large as φ5, and the towel field shrinks: the grinding time before the workpiece is 'reduced to reduce the wear of the grinding machine, and the cost of the personnel and the plastic ring of the wafer grinding ring. </ br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> Example NIE qe 'provided that such other embodiments for illustrative purposes only, are not specifically limited thereto ^ Please structures; the crystal to the first Μ!

Among them, 'the plastic ring (2 〇) can be ground before or after the grinding step of the first side (1 2) of the metal ring (1 〇) No (1 2 ) no waste trough (2 2 ), the waste trough (2 2 ) is the inner and outer circumference of the I tooth plastic ring (2〇), and each waste trough (22) Arranged at intervals, the function is to fall out of the plastic ring (2 waste generated during grinding. ° That is, the wafer grinding ring structure obtained by the above manufacturing method, such as the third and fourth figures As shown in the third figure, the front angle perspective view of the ring (A) of the round ring 1275 is shown in Fig. 4, and the back angle angle view of the wafer grinding ring (A) is shown in Fig. 4; a) is a metal ring (1〇) and a plastic ring (2 〇) that is attached to the metal ring (1〇), side (1 1 ); and is different from the conventional structure Mainly in the second side of the metal ring (i 〇) of the present invention (Work 2) is a surface-type town that has been subjected to grinding processing, smooth and has no car marks.
