Abstract: A method manufactures a head suspension by laser-welding the flexure to the load beam at a first welding spot so that a tongue is pressed against a convex portion under predetermined load. The method includes step of forming, before joining the flexure and load beam together, at least one positioning reference hole in each of the flexure and load beam within a circular range that is defined around the first welding spot with a radius equal to a distance between the first welding spot and the projection, laying the flexure and load beam one on another, inserting reference pin into the reference holes, and laser-welding the flexure and load beam to each other at the first welding spot.
Abstract translation: 一种方法通过在第一焊接点处将挠曲件激光焊接到负载梁来制造头部悬架，使得舌片在预定负载下被压靠在凸部上。 该方法包括在将挠曲和负载梁结合在一起之前形成在弯曲和负载梁的每一个中的圆周范围内的至少一个定位参考孔的步骤，其围绕第一焊接点限定，半径等于 第一焊点和投影，将挠曲和负载梁放在另一个上，将参考销插入到参考孔中，并在第一焊接点处将弯曲和负载梁激光焊接到彼此。

Abstract: A reference block which is machined from a single body of material and is a single block with reference pins integral therewith is configured for use in a method of manufacturing a head suspension by laser-welding the flexure to the load beam at a first welding spot so that a tongue is pressed against a convex portion under predetermined load. The method includes steps of forming, before joining the flexure and load beam together, at least one positioning reference hole in each of the flexure and load beam within a circular range that is defined around the first welding spot with a radius equal to a distance between the first welding spot and the projection, laying the flexure and load beam one on another, inserting the reference pins of the reference pin block into the reference holes, and laser-welding the flexure and load beam to each other at the first welding spot.
