METHOD OF MANUFACTURING GLASS CORE

摘要

The present invention relates to a manufacturing method of a glass core which enables to continuously manufacture a glass core with an automated process, comprising the steps of: providing a glass sheet; laminating an insulating sheet on the glass sheet; laminating a copper clad sheet on the insulating sheet to manufacture the glass core; laminating a buffering sheet on the copper clad sheet; pressing and temporarily hardening the buffering sheet; delaminating the temporarily hardened buffering sheet; and thermally hardening the glass core by a heater after the delaminating of the temporarily hardened buffering sheet.
