QC Profile
-The yield rate of wafers is required exceed 97%. Only few manufacturers of wafer can meet our requirements because it needs advanced technical expertise.
-We trim about 6-10 mm from the wafer's width to ensure a higher yield rate and remove any potentially damaged chips from the outer ring.
-The wire in package we use is 15 um at least while other manufacturer is widely using 12 um.
-If the yield rate of products is lower than 97% after sealing and testing, we will destroy the whole butch.
