SDI has been actively dedicated to the field of semiconductor lead frames in recent years, and this field now accounts for 80% of the company’s total revenue. Since its lead frame customers include the major semiconductor makers in the world, SDI will work hard to keep customers’ production from being interrupted and to help lowering risks while increasing profit. Semiconductor chips are used extensively in car brake systems, airplane engine regulators, and other devices on which human lives depend. As lead frames plays a key role in the functioning of semiconductors, SDI must always maintain tight quality control in its production.
