Known Good Die

National Semiconductors KGD

Micross Components Ltd, has been appointed by National Semiconductors to support the European market for Known Good Die. These are die that have been individually AC and DC tested in wafer form at worst case temperatures to guarantee performance across the full temperature range (-55 to +125°C for mil GRADE, -40 to +85°C for industrial grade, 0 to +70°C for commercial grade products).They test the same as packaged devices. Low minimum order quantity.

International Rectifier's SureCHIP

International Rectifier's SureCHIP Program is a process regimen that combines high-volume manufacturing and assembly with precision parametric testing and special packaging to deliver Known Good Die (KGD) power semiconductors. The KGD process provides measurably higher yields and is an economically viable solution in the manufacturing of multi-chip modules (MCMs). As part of the SureCHIP process, individual good die from probed and sawn wafers are transferred to a custom-designed test nest for 100% electrical and visual testing.
