Description

Technical Field

[0001] This invention relates to the field of semiconductor packaging technology, and specifically to a universal carrier for ceramic packaging of semiconductor chips. Background Technology

[0002] With the rapid development of integrated circuits, the demand for highly reliable and high-end components is increasing. Ceramic-packaged components, with their advantages of high reliability and stability, have been widely used in some specialized equipment and devices. In recent years, as the pace of domestic production has gradually accelerated, the need for the development of domestic ceramic packaging has become increasingly urgent.

[0003] Unlike plastic packaging, which involves packaging an entire substrate or frame, ceramic packaging starts with a single ceramic tube. Different packaging forms and models vary significantly in terms of ceramic shell size, pin count, and other characteristics. This unique feature of ceramic packaging makes mass production quite challenging. Different packaged products require the creation of corresponding tooling fixtures, and these fixtures need to be debugged extensively before mass production. This also increases the processing and maintenance costs of packaging tooling fixtures, which is detrimental to mass production. Summary of the Invention
