Embodiment 1

[0026] figure 1 Shown is the side view shape of the guide pin used in the method of the present invention, ie the guide pin of the present invention. The guide pin 1 is fixed on the lower clamp 2, its overall length, that is, its height, is 3.0-4.0 mm, and its top end is rounded. Furthermore, the base end portion has a diameter corresponding to the predetermined alignment accuracy, and its continuous diameter length is 0.5 to 1.2 mm, and the diameter of the tip portion is continuously tapered from the upper portion of the base end portion with two-stage curvature. As for the curvature to narrow the diameter of the tip, the radius of curvature R2 of the portion d near the base end is 4.0 to 4.5 mm, and the radius of curvature R1 of the tip portion e is 0.5 to 1.1 mm.

Abstract

The object of the present invention is to provide an alignment method that prevents the flexible printed circuit board from being caught on the guide pins used for alignment when the alignment is performed in the flexible printed circuit board processing step, and the guide pins used in the method. pin. The alignment method is a method of inserting a guide pin through a guide hole of a flexible printed circuit board so as to align the flexible printed circuit board at a specified position. The guide pin (1) formed by the above method is used to align the flexible printed circuit board (3). The guide pins are guide pins used in this alignment method.

Description

technical field [0001] The invention relates to an alignment method of a flexible printed circuit board used in electronic equipment and a guide pin used in the alignment. Background technique [0002] In the manufacture of flexible printed circuit boards, it includes various processes such as the photolithography process for forming circuits, the placement of reinforcement boards, cover layer spotting, and electrical inspection. In each process, exposure masks, cover layers, Check the alignment of the probes etc. with respect to each other. [0003] In the alignment, the guide pin protruding from the lower jig is usually inserted into a guide hole previously formed on the flexible printed circuit board to set it at a predetermined position. [0004] image 3 Shown is a guide pin 11 used for this, which is formed in a cylindrical shape with a rounded upper portion (refer to Japanese Patent Application Laid-Open No. 7-170031). The length of part of the first diameter a of t...
