Abstract: PROBLEM TO BE SOLVED: To provide an electronic structure which is capable of reducing stress in a flip chip PBGA package.
SOLUTION: The electronic structure where a board is divided into a plurality of segments is provided. A method of forming the electronic structure comprises a first step of dividing the board into the segments and a second step of electrically connecting a semiconductor element to the segments respectively. Thermal deformation caused by a thermal cycle is restrained from occurring in the semiconductor element and the soldered joint thereof.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor chip carrier assembly and its manufacturing method. SOLUTION: On a surface such as one connected electrically to a semiconductor chip 8, a flexible substrate 4 having a metallized path is provided. A reinforcing member 10 is provided near the flexible substrate 4 and jointed to the flexible substrate 4 with an adhesive composition 20. The adhesive composition 20 of a minute-hole film provided with a hardening bonding agent is provided between the flexible substrate 4 and the reinforcing member 10. A cover plate 14 is bonded to the semiconductor chip 8 and the reinforcing member 10 for jointing. By a method for manufacturing an assembly, a flexible substrate is arranged at a vacuum fixture. Here, with an adhesive composition and a reinforcing member provided, heat and pressure are applied to harden a hardening bonding agent.
