ABSTRACT:
It is the object of the invention to provide a method for manufacturing a sheet formed connector for inspecting an integrated circuit at the state of flip-chip bonding and at low pressure condition. The method for manufacturing comprises the steps of making holes on plastic insulating sheet, which is stuck to the metallic sheet, at a certain interval in both longitudinal and lateral directions, making predetermined patterned portions on the metallic sheet by etching, and melting a solder piece in each hole.
