Abstract:
1. A method for aligning first and second plate-like members, wherein the first plate-like member is made of a non-metallic material, the method comprising: forming a plurality of land portions having respective metal surfaces on the second plate-like member; forming land through holes in the first plate-like member to correspond to the land portions in the second plate-like member; aligning the first plate-like member with the second plate-like member so that the land through holes of the first plate-like member oppose corresponding land portions of the second plate-like member, and so that metal surfaces of the land portions close open ends of the corresponding land through holes; arranging solder materials on the land portions exposed in the land through holes when the first plate-like member is aligned with the second plate-like member; thereafter, thermally melting the solder materials on the land portions to form guide portions by solidification of the solder materials, the guide portions extending from the land portions and along circumferential surfaces of the land through holes; after forming the guide portions, separating the first plate-like member and the second plate-like member from each other, wherein the guide portions remain extending from the land portions after the separating; after the separating, inserting probes into respective probe through holes formed in the first plate-like member; and after inserting the probes, fitting the land through holes to corresponding guide portions to align the first plate-like member and the second plate-like member with each other, wherein engagement of the guide portions with the corresponding land through holes prevents mutually parallel movement of the first and second plate-like members.
