- An object of the present invention is to provide an IC sealant application device. Disclosure of the invention
- the method of applying the IC encapsulant with bumps according to the present invention is such that the dispense nozzle is first turned off at the first speed, which is a low speed, after the dispensing is turned off and the application is completed. After performing this first step ascending to a certain distance, the second step is then ascended at a second speed higher than the first speed, and the ascending speed is sequentially repeated several times by this method. Is gradually increased.
- the rising speed of the dispensing nozzle after applying the sealant increases stepwise, and the low speed rise in the initial stage solves the problems caused by stringing seen in the prior art, while the later stage increases the speed.
- the high speed reduces the time required for the entire ascent process and improves productivity. Can be realized.
- the rising speed at each stage of the dispensing nozzle is not constant, but can be varied according to the material (mainly viscosity) of the sealant and the coating diameter. It will be possible to select one.
- the timing for starting the application of the sealant is the same as when the dispense nozzle starts moving, and the timing for raising the dispense nozzle is simultaneously with the end of the application of the sealant.
- the time for applying the sealant, in which the sealant is reliably filled can be shortened efficiently.
- this sealant applying apparatus has a dispenser for applying the sealant, moves the dispensing nozzle to a nozzle that moves vertically, and moves the head axis in the horizontal X direction.
- the robot has an X-axis robot and a Y-axis robot that moves the substrate in the horizontal Y-direction.
- the nozzle head lifts the dispensing nozzle after the sealant is completely applied, using multiple stages with different speeds. It is characterized in that it is configured to be performed in the following manner.
- the dispensing nozzle is moved in the X direction by the X-axis robot, and the substrate is moved in the Y direction by the Y-axis robot so that the nozzle head does not hit the end surface of the IC. Then, the dispense nozzle is lowered at a constant speed by the nozzle head to a height at which a predetermined gap distance in the vertical direction between the IC and the substrate is generated. While maintaining a certain distance, the dispensing nozzle is dispensed and moved, the dispense is turned “on”, the sealant is extruded from the dispensing nozzle, and the extruded sealant is applied on the substrate.
- the dispense is turned off and the dispense nozzle is raised in several stages with different speeds by the nozzle head robot. It has the effect of raising the dispense nozzle at a high speed by increasing the speed.
