Abstract
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.
