METHOD OF MANUFACTURING SUSPENSION BOARD WITH CIRCUIT AND SUSPENSION BOARD ASSEMBLY WITH CIRCUIT

To provide a method for manufacturing a suspension board with a circuit and a suspension board assembly with a circuit capable of inspecting a formation failure of a first insulating layer and/or a second insulating layer.SOLUTION: After forming an insulating base layer 9 on one surface in a thickness direction of a metal supporting layer 12, a conductive pattern 10 is formed on one surface in the thickness direction of the insulating base layer 9, and then a cover insulating layer 11 is formed on one side in the thickness direction of the insulating base layer 9. Then, in an inspection section 4, an inspection insulating layer is formed on one surface in the thickness direction of the metal supporting layer 12 by the same step as the formation of the insulating base layer 9 and/or the cover insulating layer 11, and a first insulating layer inspection probe is brought into contact with the inspection insulating layer to inspect conduction with the metal supporting layer 12.SELECTED DRAWING: Figure 2 【課題】第１絶縁層および／または第２絶縁層の形成不良を検査することができる回路付サスペンション基板の製造方法および回路付サスペンション基板集合体を提供する。【解決手段】金属支持層１２の厚み方向一方面にベース絶縁層９を形成した後、ベース絶縁層９の厚み方向一方面に導体パターン１０を形成し、次いで、ベース絶縁層９の厚み方向一方側にカバー絶縁層１１を形成する。そして検査部４に、ベース絶縁層９および／またはカバー絶縁層１１の形成と同一工程により、金属支持層１２の厚み方向一方面に検査絶縁層を形成し、検査絶縁層に第１絶縁層検査プローブを接触させて、金属支持層１２との導通を検査する。【選択図】図２
