Abstract
The invention discloses an acid cleaning process used for a diode, which consists of four times of cleaning; the former three times of cleaning are carried out in deionized water by using ultrasonic under the conditions of identical ultrasonic powder and different resistivity, temperature and flux. The cleaning of the first time is carried out in the deionized water with a certain flux under the heating condition; the cleaning of the second time and the third time are carried out only in the deionized water; the cleaning of the fourth time uses the anhydrous alcohol to carry out the dehydration on the diode. The process of the invention effectively removes the impurities on the surface of the diode by the cleaning under the conditions of heating and ultrasonic, and leads the surface of the diode to be cleaner; the deionized water is used, thus saving the water resource; the cleaning time is shortened and the production efficiency is improved by the multi-step cleaning.
Description
Technical field
The present invention relates to a kind of cleaning of diode, be specifically related to a kind of by ultrasonic wave, heat and clean, the cleaning of the diode that pickling machine is flowed out.
Background technology
At present, two kinds of common cleaning and ultrasonic waves for cleaning are taked in the cleaning of diode.Common cleaning is when cleaning products, and the cleannes of product are not enough, influence product quality.Though ultrasonic waves for cleaning has improved the cleannes of product, still can not tackle the problem at its root, and scavenging period is long relatively slightly.
Summary of the invention
The invention provides a kind of by ultrasonic wave, the cleaning of the diode that pickling machine is flowed out that cleans of heating.
In order to solve above technical problem, the cleaning of a kind of diode that pickling machine is flowed out of the present invention, be made of four cleanings, all use ultrasonic waves for cleaning in first three time cleaned, its innovative point is: clean the cleaning of heating in the deionized water of certain flow the described first time; Only clean for the second time and for the third time and in deionized water, clean; The 4th cleaning dewatered to diode for absolute ethyl alcohol.
Deionization resistivity of water 〉=10M Ω CM that clean the described first time.
Temperature 45-50 ℃ of the deionized water that described first time cleans.
The flow of the deionized water that clean the described first time is 450-550L/h.
The water of described second and third time cleaning is deionized water.
Described the 4th cleaning absolute ethyl alcohol dewaters to diode.
All clean the ultrasonic wave that all uses 1KW, guarantee to clean fully.
The advantage of above technology is:
1, adopts above-mentioned technology,, effectively remove the impurity on diode surface, the diode surface is more cleaned by the ultrasonic waves for cleaning of heating.
2, connect use deionized water, conserve water resource (2000-2500L/h).
3, shortened scavenging period by multistage cleaning, enhanced productivity.
Embodiment
This technology is totally four cleaning processes, and it cleans as follows respectively:
Clean for the first time: pickling machine flows out product, enters in first rinse bath, feeds the above deionized water of resistivity 10M Ω CM in the groove, this current heater via temperature is controlled in about 45 ℃, flow control is at 500L/h, and product rests in the rinse bath, by the flowing water ultrasonic cleaning.
Clean for the second time: product enters second ultrasonic cleaning tank behind first rinse bath, be the above deionized water of 10M Ω CM in the groove, cleaning products once more in this groove, the water that this groove uses be after grade used deionized water.
Clean for the third time: directly feed the above deionized water of 12M Ω CM in the 3rd ultrasonic cleaning tank, flow control is at 2000-2500L/h.
More than clean all by ultrasonic waves for cleaning for three times, cleaning each time, ultrasonic time was controlled at about 1 minute.
Clean for the 4th time: add the absolute ethyl alcohol more than 98% in the ultrasonic cleaning tank, the product of three ultrasonic cleaning in front is dewatered.
Claims (1)
1, a kind of cleaning of the diode that pickling machine is flowed out, constitute by four cleanings, in cleaning, first three time all use ultrasonic waves for cleaning, it is characterized in that: clean the cleaning of in the deionized water of certain flow, heating the described first time, the deionization resistivity of water that cleans for the first time wherein: 〉=10M Ω CM, temperature is at 45-50 ℃, flow 450-550L/h, ultrasonic power: 1KW; Only clean for the second time and for the third time and in deionized water, clean: the deionization resistivity of water that cleans for the second time wherein: 〉=10M Ω CM, temperature is at 25 ℃, flow 2000-2500L/h, ultrasonic power: 1KW, the deionization resistivity of water of Qing Xiing for the third time: 〉=12M Ω CM, temperature is at 25 ℃, flow 2000-2500L/h, ultrasonic power: 1KW; With absolute ethyl alcohol diode is dewatered for the 4th time, wherein the 4th cleaning carried out processed to diode, ultrasonic power for the absolute ethyl alcohol with concentration 〉=98%: 1KW; The use amount of absolute ethyl alcohol is decided according to product category, must replenish absolute ethyl alcohol when the absolute ethyl alcohol temperature surpasses 70 ℃.
