发明名称 Apparatus for reducing warping of plastic packages
摘要 Methodology for reducing the warpage in thinly packaged electrical components, and electrical components packaged according to the method. The method taught herein is to make the gates themselves compliant, or flexible, thereby absorbing the stresses which would otherwise cause package deformation, including warpage. The present invention teaches two preferred embodiments for attaining this novel solution, including the adoption of wide, thin gates and the use of serpentine gates.
