Ultrasonic txau tiv thaiv zaj duab xis tshwj xeeb txheej ua ntej silicon wafer txiav

Ultrasonic txau tiv thaiv zaj duab xis tshwj xeeb txheej ua ntej cov tshuaj lom neeg ua haujlwm rau silicon ua ntej txiav, sib tsoo, thiab polishing los tiv thaiv lub wafer thiab ua pob. Tshuaj lom neeg sib xws suav nrog z -} lub tsho tiv no, PMMA, thiab lwm yam tshuaj yooj yim. Funsonic lub ntsia lub cev tuaj yeem raug kho kom tau raws li cov neeg siv khoom sib tw thiab cov nyom rau cov yeeb yaj kiab tiv thaiv ua ntej silicon wafer txiav.
Lub ultrasonic txau tiv thaiv zaj duab xis tshwj xeeb txheej ua ntej silicon wafer txiav tej zaum yuav tau siv rau txhua qhov tuab ntawm cov tuab los ntawm submicron rau ntau dua 100 micrd. Lub txheej txheej txheej yog ib txoj kev xaiv tau rau lwm cov txheej txheem txheej xws li teb thiab ua tshuaj tsuag ib txwm muaj.

Ultrasonic nozzles muaj cov ntawv thov tseem ceeb hauv photocaphogr ua. Cov tshuab hluav taws xob semiconduct siv ultrasonic txau thev naus laus zis rau cov tshuaj tsuag phom sij hauv sicicon thiab cov tshuaj lom neeg uas tuaj yeem tso saib cov khoom siv kho tshiab. The spraying process involves inserting the nozzle above the chip, and then controlling the ultrasonic nozzle through XYZ three-axis and servo motor to evenly distribute the coating. Raws li cov tshuaj tsuag ntawm ultrasonic nozzle yog maj mam, nws tuaj yeem txhim kho cov tshuaj lom neeg, txhim kho kev txhim kho, thiab txo cov khoom pov tseg thiab cov khoom pov tseg. Cov ntaub ntawv qhia tau hais tias ultrasonic tsuag technology tuaj yeem txuag tau mus txog 70% ntawm cov ntaub ntawv thiab txhim kho kev tswj hwm ntawm qhov tseem ceeb.
Piv nrog li ib txwm muaj cov txheej txheej sib luag, qhov nce ntawm ultrasonic nozzles yog tias lawv tuaj yeem faib tshuaj ntau dua thiab tsawg kawg ntawm kev faib tawm hauv pem teb nro. Tsoos kev sib txig khoom lag luam sau cov tshuaj uas muaj cov duab ntawm cov puddles lossis dej ntws mus rau hauv lub keeb, thiab tom qab ntawd dispersing lawv mus rau hauv pem teb ntawm centrifugal quab yuam. Qhov no yam yuav tsum tau muab kev qhia txog qhov kub thiab ntsuas kub thiab hnyav evaporation kom paub tseeb tias kev ncaj ncees thiab kev sib luag ntawm cov txheej txheem. Ultrasonic nozzles, ntawm qhov sib txawv ntawm tes, atomize cov ntaub rau hauv cov kab ke tsis yog {} Cov rog txiav, thiab yuav tsis muaj kev lom zem ntawm kev tso tseg lossis kev tso tseg.
