Abstract

The present invention relates to an operation number-counting piezoelectric dispenser, more specifically to a dispenser equipped with a piezoelectric pump for dispensing a solution by using a piezoelectric element as an actuator. An operation number-counting piezoelectric dispenser according to the present invention allows a piezoelectric actuator to be replaced before damage occurs thereto by preemptively predicting same, thereby preventing process loss and production of defective products, and thus has the benefit of enhancing productivity.

Description

technical field [0001] The present invention relates to a life-calculating piezoelectric dispenser, and more particularly to a dispenser having a piezoelectric pump (piezoelectric pump) that dispenses a solution using a piezoelectric element as an actuator. Background technique [0002] Dispensers that supply liquid solutions such as water, oil, and resin in a fixed amount are used in various fields such as semiconductor manufacturing and medical fields. [0003] In particular, in the semiconductor manufacturing process, the dispenser is often used in the underfill process, and the dispenser is also frequently used for filling the inside of the package of the semiconductor device with resin. In the process of manufacturing light emitting diode (Light Emitting Diode, LED) components, the dispenser is used in the process of coating the fluorescent liquid mixed with fluorescent material and resin on the LED chip. [0004] This type of dispenser uses a pump (pump) that receives...
