    • The present invention discloses a method for minimizing warpage in the electronic products, and the structures of such electronic products as well. Groove holes are formed into the insulating material layer or several layers. The groove holes can be processed by laser drilling or by other suitable means. A cured epoxy adhesive will fill the groove holes after the heat and pressure treatment performed to the circuit structure. The electronic product may contain several insulating layers and embedded electronic components connected to a wiring layer. A double-stacked symmetrical structure can also be manufactured. Asymmetrical structures with different sized embedded components can be handled as well. The groove holes can be shaped as straight short lines, ellipses, crosses, circles etc, or as any combination of different shapes. The groove holes can be scratched so that they locate outside strips, between the strips of a panel, between blocks of the strip, between modules of the block or between embedded components of the module.
    • 本发明公开了一种使电子产品中的翘曲最小化以及这种电子产品的结构的方法。 凹槽形成绝缘材料层或几层。 槽孔可以通过激光钻孔或其他合适的方式加工。 在对电路结构进行热和压力处理后,固化的环氧树脂粘合剂将填充凹槽。 电子产品可以包含几个绝缘层和连接到布线层的嵌入式电子部件。 也可以制造双层对称结构。 也可以处理不同大小的嵌入式组件的非对称结构。 槽孔可以形成为直线短线,椭圆形,十字形,圆形等,也可以是不同形状的任何组合。 凹槽可以被划伤,使得它们定位在条带之间,面板条之间,条带的块之间,块的模块之间或模块的嵌入部件之间。
