Abstract

PROBLEM TO BE SOLVED: To provide an electronic part mounter and a mounting method in which defects in mounting can be prevented by performing the mounting while taking in account the mounting height. SOLUTION: In a method for picking up an electric part P by means of a suction nozzle 7a and mounting it on a board 3, a cream solder 3a for the electric part P on the board 3 is irradiated with laser slit from a laser generator 12 and the image thereof is picked up by means of a camera 11. Shift d of the laser slit between the upper surface of the cream solder 3a and the upper surface of the board 3 is then detected and the height of the upper surface of the cream solder 3a is measured. Subsequently, the height of the suction nozzle 7a stop at the mounting position is calculated based on the measurements and descending operation of the suction nozzle is controlled when the electronic part is mounted. According to the method, a correct mounting height is ensured and defects can be reduced after mounting.

2. Description of the Related Art In recent years, with the miniaturization and narrowing of pitch of electronic parts, high mounting position accuracy is required when electronic parts are mounted on a substrate. For this reason, a method of recognizing the image of the board at the time of mounting, performing position correction based on the recognition result, and positioning the electronic component with respect to the mounting portion is generally adopted, and thereby the mounting position accuracy of the board surface in the horizontal direction is remarkably improved. Has improved.

However, in the conventional mounting method using the above-described image recognition, the height of the mounting portion is not detected at all, and the mounting is performed according to a preset mounting height at the time of mounting. The lowering operation of the nozzle was controlled. For example, when mounting electronic components after applying cream solder to the electrode surface of the board, the thickness of the cream solder has not been considered in the conventional mounting operation, and the electrode on the mounting data set as the mounting height at the time of mounting is not considered. It has been common practice to lower an electronic component held by a suction nozzle to a surface position.

[0004] For this reason, the cream solder is often crushed by the electronic components and protrudes in the lateral direction. In some cases, the cream solder melted in the reflow process is connected to the solder on the adjacent electrode to form a solder bridge. Extrusion of the cream solder has been a cause of failure after mounting, for example, the solder balls have been separated and come into contact with the circuit pattern on the substrate surface after mounting to cause a short circuit. As a countermeasure against this, it is conceivable to correct the mounting height by the thickness of the cream solder. However, since the thickness of the cream solder applied to the substrate is not constant, the method using a fixed correction value does not provide a sufficient correction effect.

That is, cream solder is supplied onto a substrate by a method of dispensing, screen printing, or the like. However, in the method of dispensing, variations in thickness are essentially unavoidable. The printing thickness is not always constant, and the printing thickness varies depending on the degree of evaporation of the solvent in the cream solder. As a result, the height of the cream solder surface on which the electronic component is mounted varies depending on each mounting portion, and it has been difficult to reliably prevent the cream solder from protruding.

[0006] In addition to the above-mentioned variation in the thickness of the cream solder, the mounting height may not be constant. For example, even when the substrate itself is deformed, or when an electronic component is further mounted on an already mounted electronic component, the actual mounting height does not always match the mounting data and shows a variation. This variation in mounting height often causes a mounting failure. As described above, in the conventional mounting of electronic components, there is a problem that a failure after mounting may occur due to a failure to perform a mounting operation in consideration of a height of a mounting portion.
