wafer back grinding process

High-precision machining company

The wafer is half-cut with a special dicing saw. Then, die singulation occurs when the wafer is thinned below the level of this cut. The wafer then goes to the in-line DBG Mounter, which gently peels off the protective grinding tape, completing the process.
