  • Patent number: 8435641
    Abstract: A method for manufacturing a heat resistant flexible laminate effectively enabling avoidance of not only visual defects but occurrence of dimensional changes, and a heat resistant flexible laminate are provided. In a process for laminating a heat resistant adhesive material and a metallic foil by thermal lamination, a film-like protective material is disposed between a pressurized surface and the metallic foil at the time of thermal lamination. At this time, coefficients of linear expansion in a temperature range of 200 degree C. to 300 degree C. of the heat resistant adhesive material and the protective material are within a range of a coefficient of linear expansion of the metallic foil ±10 ppm/degrees C. Thereby, occurrence of visual defects is not only effectively avoidable, but excellent dimensional change after etching may be exhibited.

Lower surface-side lands with solder balls coupled thereto respectively and testing lands with solder balls not coupled thereto are formed on a lower surface of a wiring substrate. To suppress the occurrence of contact imperfection between the testing lands and land contacting contact pins provided in a probe socket, the diameter of each testing land is set larger than the diameter of each lower surface-side land. Even when the wiring substrate is reduced in size, electrical characteristic tests using the testing lands can be done with high accuracy.
