By providing this high definition, highly reliable lead frame we aim to expand the use of semiconductor Quad Flat Non-leaded package (QFN) for vehicles.

DNP Developed Lead Frame Features

DNP has taken advantage of our microfabrication technology developed over many years to successfully achieve the configuration of lead frame silver plated area of ±25um. It has also been possible to maintain high level reliability by improving the adhesion of the mold compound and the lead frame.

The Joint Electron Device Engineering Council (JEDEC) has established Moisture Sensitivity Levels (MSL) with the objective of preventing a variety of phenomena from volume expansion due to the absorption and vaporization of air-borne moisture in the mold compound. And DNP is pleased to announce that our newly developed product has been verified the highest MSL 1 ranking.

Going Forward

DNP will propose the newly developed high definition, highly reliable lead frame to post-processing manufacturers and expand this business. We will also strengthen our facilities to meet increasing demand, and plan to double our production capacity by FY 2023 compared to FY 2020.
