Vuam choj:

Tus choj txuas yog qhov sib txuas hluav taws xob tsis zoo ntawm cov neeg siv hluav taws xob uas tsis xav tau vim yog ib qho me me ntawm cov laug. Lawv kuj tseem hu ua “luv Circuit Court” hauv PCB cov lus siv. Nws nyuaj rau txheeb xyuas cov hlua txuas thaum cov khoom sib txuam sib txawv tau koom nrog. Yog tias nws tsis raug daws, nws tuaj yeem ua rau muaj kev puas tsuaj rau lwm yam khoom siv thiab cov laug cam. Lub npog ntsej muag vuam (piv txwv li, txheej tuab ntawm cov polymer tau siv rau cov kab tooj liab ntawm cov ntawv luam tawm hauv Circuit Board los tiv thaiv nws los ntawm oxidation thiab zam kev txuas tus choj txuas ntawm cov pawm. Lub npog ntsej muag vuam no yog qhov tsim nyog rau kev tsim khoom ntau ntawm PCBS, tab sis nws tsis muaj txiaj ntsig zoo thaum siv cov khoom sib txuas PCB. Rau cov phiajcim hluav taws xob yuav tsum tau siv lub tshuab hluav taws xob ncaj qha, cov kais dej da dej thiab cov txheej txheem rov ua dua tshiab yog qhov siab. Txhawm rau zam kev vuam Bridges thaum sib dhos PCB, nws yog thawj qhov tsim nyog los txiav txim siab hom vuam npog uas tsim nyog siv thaum PCB sib dhos. Qhov no tuaj yeem yog kev txiav txim siab zoo thaum tau txais PCB txheej txheem tsim nyog thiab hom PCB rau koj txoj haujlwm.

Cov tuam txhab tsim khoom siv hluav taws xob yuav tsum tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm txhua hom yeeb yaj kiab ua ntej txiav txim siab seb puas yuav xaiv cov tshuaj epoxy, kua duab yees duab yaj yeeb yaj kiab (LPSM) lossis zaj duab xis qhuav zaj duab xis yaj yeeb yaj kiab (DFSM). Lawv tuaj yeem pab PCB cov tuam txhab lag luam sab laj thiab nrhiav kev ua kom zoo PCB los ua ke los ntawm cov txheej txheem meej thiab txheej txheem tsim khoom PCB. Rau txhua tus tuam txhab tsim khoom siv hluav taws xob, tiv thaiv cov hlua txuas yuav suav nrog kev nqis peev ntxiv ntawm lub sijhawm thiab nyiaj txiag, tab sis nws tuaj yeem pab koj ua tiav qhov txiaj ntsig zoo mus sij hawm ntev.

Yog vim li cas rau vuam choj:

Lub hauv paus ua rau txuas cov hlau txuas yog PCB txheej txheem tsis raug. Cov pob me me ntawm nws cov khoom siv thiab lub tswv yim ntawm kev siv cov khoom sib xyaw tsis txaus tau nce ntxiv vim tias xav tau los qhia ntau qhov kev cog lus thiab nrawm dua thev naus laus zis. Qhov no yog qhov nyuaj rau oems, xav kom zoo thiab tsim nyog PCB txheej txheem. Lawv feem ntau xaus kev cuam tshuam ntawm PCB txheej txheem txhawm rau coj cov khoom lag luam tshiab mus rau kev lag luam.

Lwm qhov laj thawj ntawm kev txuas nrog suav nrog tsis muaj qhov txuas tsis zoo ntawm cov pawm ntawm lub rooj tsav xwm hauv Circuit Court.Cov txheej txheem polymer tsis txaus ntawm COPPER kab kab ntawm PCB, feem ntau hu ua daim npog ntsej muag, tseem ua rau muaj teeb meem nrog tus choj txuas. Thaum cov cuab yeej sib nrug yog 0.5 hli lossis tsawg dua, qhov tsis sib xws ntawm kev tshem tawm cov ntaub ntawv kuj tseem tuaj yeem ua tus choj. Cov qauv txheej txheem tsis raug tuaj yeem ua rau muab tshuaj txhuam ntau dhau, uas tuaj yeem ua rau Bridges. Vim tias kev sib khi tsis zoo ntawm PCB thiab phaj phom, qhov tsis raug ntawm cov qauv, qhov ua yuam kev hauv qhov chaw ntawm cov khoom sib txuas saum npoo lossis hauv kev sib piv nrog PCB, cov ntawv sau tsis zoo muab tshuaj txhuam, faib tsis sib luag ntawm cov tshuaj muab tshuaj txhuam, cov no yog cov teeb meem tshwm sim uas ua rau choj txuas thaum PCB sib dhos.

Cov kev tiv thaiv:

Txheeb xyuas tias txhua lub xaim hlau tau xeb nrog qhov tsis kam ua haujlwm nruab nrab ntawm lawv thiab tsis tuaj yeem siv tau vim muaj kev nruj nruj, thiab tom qab ntawd nws piav qhia qhov kev hloov pauv nyob ib puag ncig qhov tshwj xeeb ntawd. Qhov kev pom zoo 0.127 hli tuab vuam cov qauv, cov hlau tsis muaj hlau nrog laser txiav kuj tseem haum rau 0.5 hli cov cuab yeej sib nrug. Cov no yog kev ceev faj kom tsis txhob txuas cov kab txuas thiab tau txais kev daws teeb meem PCB zoo meej.
