Development of Lapping Tape with Uneven Pattern Surface by Using Backing Material of Polyester Film of Difficult-Crystallization

摘要

Recently, there are electronically and optical devices with high performance and high function. Under these circumstances, lapping tape is crucial. Because polishing by using lapping tape can get fine surface finishing very efficiency and keep working environment clean. However, lapping tape based on a polyester film backing material has some problems, which are chip pockets on its polishing surface are narrow. Then new lapping tape, which has better polishing functions, has been wanted. So this study developed new lapping tape with uneven pattern on its polishing surface which backing material of polyester film of difficult-crystallization was used.
