Yuav ua li cas Yog tias Cov Txiag Circuit Court yog them nrog tooj?

Yuav ua li cas yog tias lub rooj tsav xwm hauv Circuit Court yog them nrog tooj?

PCB Circuit Court board tooj liab clad laminate teeb meem ib qho, kom muaj peev xwm taug qab cia.

Nws tsis tuaj yeem tsim cov naj npawb ntawm PCB Circuit Board tsis tau ntsib qee qhov teeb meem, uas yog qhov tseem ceeb vim yog cov khoom siv ntawm PCB tooj liab-clad laminate. Thaum cov teeb meem zoo tshwm sim hauv cov txheej txheem tsim khoom tiag tiag, nws zoo li feem ntau vim yog cov khoom siv PCB substrate. Txawm hais tias sau kom zoo thiab siv cov txheej txheem PCB laminate cov kev qhia tshwj xeeb tsis tau qhia meej cov khoom ntsuas uas yuav tsum tau nqa tawm los txiav txim siab tias PCB laminate yog qhov ua rau cov teeb meem kev tsim khoom. Nov yog qee qhov teeb meem feem ntau ntsib PCB laminate teeb meem thiab yuav ua li cas kom paub meej.

Thaum ntsib teeb meem PCB laminate, koj yuav tsum txiav txim siab ntxiv rau PCB laminate los ua kom tiav. Feem ntau, yog tias qhov kev qhia tshwj xeeb no tsis enriched, nws yuav ua rau muaj kev hloov pauv tsis tu ncua thiab yog li ua rau cov khoom lag luam poob qis. Feem ntau, cov teeb meem khoom siv los ntawm kev hloov qhov zoo ntawm PCB laminates tshwm sim hauv cov khoom lag luam tsim los ntawm cov tuam txhab siv cov khoom sib txawv ntawm cov khoom siv raw khoom lossis siv cov nias nrawm sib txawv. Tsawg cov neeg siv khoom tuaj yeem tuav cov ntaub ntawv ntau txaus, kom lawv tuaj yeem paub qhov txawv tshwj xeeb nias lossis cov khoom ntim ntawm cov xaib. Yog li ntawd, nws feem ntau tshwm sim tias PCB raug txuas ntxiv tsim thiab teeb tsa nrog cov khoom sib txuas, thiab kev tawm tsam tsis tu ncua tshwm sim hauv cov dej da dej, vim li no ntau yam kev siv dag zog thiab cov khoom kim. Yog tias tus lej ntawm tus nqi them tam sim ntawd, lub chaw tsim tshuaj paus PCB laminate tuaj yeem tshawb xyuas cov txheej txheem ntau txheej ntawm cov ntawv lo, tus lej ntawm cov ntawv ci tooj liab, thiab lub voj voog kho kom zoo. Hauv lwm lo lus, yog tias tus neeg siv tsis tuaj yeem muab cov kev txuas ntxiv mus txuas ntxiv nrog cov kev tswj hwm zoo ntawm PCB chaw tsim tshuaj paus, qhov no yuav ua rau tus neeg siv poob ntev ntev. Cov nram qab no piav qhia txog cov teeb meem dav dav uas muaj feem xyuam nrog cov khoom hauv substrate hauv PCB txoj kev tsim vaj huam sib luag.

PCB Circuit Board board clad laminate teeb meem ob, teeb meem saum npoo

Cov tsos mob: Cov nplaum tsis zoo ntawm cov ntaub ntawv luam ntawv, kev nplaum tsis zoo ntawm daim hlau, qee yam tsis tuaj yeem tsoo, thiab qee qhov tsis tuaj yeem muag.

Muaj cov kev soj ntsuam: kev kuaj pom feem ntau yog ua los ntawm kev ua cov cim dej tsis pom ntawm cov npoo ntawm pawg thawj coj:

Qhov uas tsim nyog:

Vim hais tias ntawm qhov ceev heev thiab du nto tshwm sim los ntawm cov zaj duab xis tso tawm, lub npoo tooj liab tsis zoo dhau ntawm lub teeb ci.

Nquag nyob rau sab uas tsis tau ua tiav ntawm lub laminate, cov chaw tsim khoom laminate tsis tshem tus tso tawm.

Pinholes ntawm cov ntawv ci tooj liab ua rau cov roj tawm kom ntws tawm thiab nthuav tawm rau saum npoo ntawm cov ntawv ci tooj liab, uas feem ntau tshwm sim ntawm cov ntawv ci tooj liab uas yog cov thinner dua li ntawm 3 / 4 ounce phaus tshwj xeeb.

Tooj liab cov ntawv ci cov lag luam siv cov tshuaj antioxidant ntau dhau rau ntawm cov ntawv ci tooj liab.

Laminate tuam txhab tau hloov cov txheej txheem txheej txheem txheej, tshem tawm nyias, los yog txhuam cov hau kev.

Vim tias kev ua haujlwm tsis raug, muaj ntau yam ntiv tes lossis roj.

Siv roj thaum xuas nrig ntaus, txiav los yog ua haujlwm.

Daws daws tau:

Ua ntej ua ib qho kev hloov pauv ntawm kev tsim cov khoom laminate, sib koom tes nrog laminate.

Chaw tsim tshuaj paus thiab taw qhia tus neeg siv' s cov khoom kuaj sim.

Nws raug pom zoo tias cov neeg tsim ua laminate siv cov yeeb yaj kiab zoo li ntaub lossis lwm yam khoom tso tawm.

Hu rau cov chaw tsim khoom ntawm cov ntawv laminate kom tshawb xyuas txhua pob ntawm cov ntawv ci tooj liab uas tau ua tsis tiav; thov ib qho kev pom zoo uas pom zoo los ntawm kev tshem cov qog.

Nug cov chaw tsim tshuaj paus ntawm lub laminate rau cov txheej txheem tshem tawm. Nws feem ntau pom zoo kom siv cov kua roj hydrochloric acid, tom qab ntawd los ntawm kev siv tshuab zom kom tshem nws.

Hu rau cov chaw tsim khoom siv laminate kom siv cov cuab yeej kho tshuab lossis tshuaj tua kab.

Qhia cov neeg ua haujlwm hauv txhua tus txheej txheem coj daim iav tooj liab nrog cov hnab looj tes. Tshawb nrhiav seb cov laminated board muaj cov ntawv padding haum lossis ntim hauv lub hnab thaum thauj khoom, thiab daim ntawv padding muaj cov ntawv me me tsis meej, thiab lub hnab ntim khoom tsis muaj av. Ua zoo saib xyuas kom tsis muaj leej twg kov thaum siv cov xab npum muaj silicone Copper ntawv ci.

Degrease txhua laminates ua ntej plating lossis duab hloov txheej txheem.
