Yuav ua li cas ntxuav PCB nrog ultrasonic da dej?

PCB board tseem hu ua luam tawm Circuit Board. Hais lus nruj me ntsis, lub rooj tsav xwm luam tawm yog sawv cev los ntawm PCB tsis yog" pcb board". Lub pcb yog lub chaw muab kev sib txuas hluav taws xob rau cov khoom siv hluav taws xob thiab cov tub ntxhais ntawm cov khoom siv hluav taws xob. Nws tuaj yeem yog txhua yam duab lossis loj, nyob ntawm daim ntawv thov ntawm cov khoom siv hluav taws xob. Puas muaj peev xwm ntxuav PCB hauv ib da dej ultrasonic?

Cov lus teb yog tiag tiag. Kev siv tshuab ntxuav dej yog qhov kev txhim kho ntawm kev siv tshuab huv yav tom ntej, thiab nws yog ib qho tsim nyog los tsim cov dej ntshiab huv thiab tshem tawm cov kev cob qhia dej. Siv dej ua qhov nruab nrab ntawm kev ntxuav, surfactants, additives, corrosion inhibitors thiab chelating agents yog ntxiv rau hauv dej los tsim cov tshuaj ntxuav dej ntau. Muaj peev xwm tshem tawm cov kuab tshuaj thiab cov dej tsis huv.Ultrasonic da dej ntxuav tuaj yeem ua tiav kev tu siab, thiab nws tuaj yeem ntxuav qhov chaw uas tsis tuaj yeem ntxuav manually.

Yog tias PCB tsis khaws cia kom huv si, qee yam khoom siv thaum lub sij hawm PCB los ua ke lossis hloov kho tuaj yeem ua rau muaj teeb meem loj hauv kev ua haujlwm. Ib qho teeb meem uas tshwm sim hauv hom no yog flux. Flux yog cov tshuaj siv tshuaj siv los pab ua cov khoom sib txuas rau PCB. Txawm li cas los xij, nws yog qhov nyuaj siab tias yog tias nws tsis raug tshem tawm tom qab soldering, cov flux yuav ua rau lub ntsej muag rwb thaiv tsev tsis zoo ntawm PCB, thiab qhov kev ua tau zoo hauv Circuit Court yuav raug degraded tiag tiag hauv cov txheej txheem!

1) PCB degreasing: tshem tawm cov roj thiab oxides ntawm qhov chaw ntawm daim duab kos kom paub meej tias cov tooj liab yog huv.

Cov kauj ruam los ntxuav cov tooj liab nto:

1. Qhuav zaj duab xis nias

2. Ua ntej txheej txheej oxidation kho

3. Tom qab drilling (tshem cov slag, tshem tawm cov colloid uas tsim thaum lub sij hawm drilling txheej txheem kom nws coarser thiab huv si) (tshuab sib tsoo phaj: siv ultrasonic tu kom huv si tag nrho lub qhov, thiab cov hmoov tooj liab thiab adhesion nyob rau hauv lub qhov quav yog tshem tawm)

4. Ua ntej tshuaj lom neeg tooj liab 5. Ua ntej tooj liab plating 6. Ua ntej xim ntsuab 7. Ua ntej tshuaj tsuag tin (los yog ua ntej lwm yam txheej txheem kev kho mob ntawm soldering pad) 8. Lub rooj tsavxwm tsis huv ntawm cov ntiv tes kub ua ntej nickel plating kuj pom muaj ntau cov suab nrov sab nraud. . Tom qab ntxuav hauv ib da dej ultrasonic thiab qhuav tag, tus choj sensor voltage yog ruaj khov li pob zeb.
