Yuav daws qhov teeb meem ntawm tooj liab clad laminate ntawm PCB

Nov yog qee qhov teeb meem feem ntau ntawm PCB pawg thawj coj thiab yuav ua li cas thiaj paub tseeb lawv. Thaum muaj teeb meem ntawm PCB laminate ntsib, nws yuav tsum raug txiav txim siab ntxiv nws rau PCB Laminate specification. Yuav ua li cas thiaj daws tau qhov teeb meem ntawm tooj liab clad laminate ntawm PCB?

Nws tsis tuaj yeem tsim cov lej ntawm PCB yam tsis tau ntsib qee qhov teeb meem, uas feem ntau yog los ntawm cov khoom siv ntawm PCB tooj liab-clad laminate. Thaum teeb meem zoo tshwm sim hauv cov txheej txheem tsim khoom, nws zoo li cov khoom siv hauv PCB feem ntau yog qhov ua rau muaj teeb meem. Txawm tias ua tib zoo sau thiab siv cov lus qhia tshwj xeeb rau PCB laminates tsis tau hais qhia cov khoom ntsuas uas yuav tsum tau ua los txiav txim tias PCB laminates yog qhov ua rau muaj teeb meem txheej txheem tsim khoom. Nov yog qee qhov teeb meem PCB Laminate feem ntau thiab yuav ua li cas thiaj paub tseeb tias lawv.

Thaum muaj teeb meem ntawm PCB laminate ntsib, nws yuav tsum raug txiav txim siab ntxiv nws rau PCB Laminate specification. Feem ntau, yog tias qhov kev qhia tshwj xeeb no tsis txaus, nws yuav ua rau muaj kev hloov pauv tsis tu ncua thiab ua rau cov khoom pov tseg. Feem ntau, cov khoom siv teeb meem tshwm sim los ntawm kev hloov pauv ntawm PCB Laminate zoo tshwm sim hauv cov khoom lag luam tsim nrog cov khoom sib txawv ntawm cov khoom siv los yog sib txawv nias ntau. Tsawg tus neeg siv muaj cov ntaub ntawv txaus los cais qhov tshwj xeeb nias lub nra lossis cov khoom ntim ntawm qhov chaw ua haujlwm. Yog li nws feem ntau tshwm sim tias PCB tau tsim tas li thiab teeb tsa nrog cov khoom, thiab warpage tau txuas ntxiv tsis tu ncua hauv cov kab laug sab laug, uas ua rau ntau lub zog ua haujlwm thiab cov khoom kim. Yog tias cov naj npawb thauj khoom tuaj yeem pom tam sim ntawd, PCB Cov Chaw Tsim Khoom Laminate tuaj yeem tshawb xyuas cov lej ntawm cov tshuaj, cov ntawv tooj liab, kho lub voj voog, thiab lwm yam Hauv lwm lo lus, yog tias tus neeg siv tsis tuaj yeem muab txuas ntxiv nrog kev tswj hwm zoo ntawm PCB Chaw Tsim Tshuaj Laminate , tus neeg siv nws tus kheej yuav raug kev poob rau lub sijhawm ntev. Cov hauv qab no piav qhia cov teeb meem dav dav ntsig txog cov khoom siv hauv txheej txheem tsim khoom ntawm PCB.

Cov tsos mob: ua tsis tau zoo ntawm cov ntaub ntawv luam tawm, ua tsis tau zoo ntawm txheej, qee qhov tsis tuaj yeem pleev xim, thiab qee qhov tsis tuaj yeem siv tau.

Cov txheej txheem tshuaj xyuas tau: kev tshuaj xyuas qhov muag feem ntau yog ua los ntawm kev ua kom pom cov cim dej ntawm daim phaj:

Cov ua tau:

Vim tias qhov ntom ntom ntom ntom nti thiab du nto tshwm sim los ntawm cov yeeb yaj kiab demoulding, cov nplaim tooj liab tsis muaj xim zoo nkauj heev.

Feem ntau, cov chaw tsim khoom laminate tsis tshem tus neeg sawv cev tso tawm ntawm qhov tsis muaj txheej txheej ntawm laminate.

Pinholes hauv cov ntawv ci tooj liab ua rau cov dej ntws tawm thiab sib sau rau saum npoo ntawm cov ntawv ci tooj liab, uas feem ntau tshwm sim ntawm cov ntawv ci tooj liab thinner dua 3/4 oz qhov hnyav tshwj xeeb.

Cov neeg ua tooj tooj liab siv cov tshuaj tua kab mob ntau dhau rau saum cov ntawv ci tooj liab.

Cov neeg tsim khoom laminate tau hloov cov txheej txheem txheej, tso cov ntawv, lossis txheej txheem txhuam.

Vim yog kev ua haujlwm tsis raug, muaj ntau cov ntiv tes los yog roj av.

Cov roj tau pleev xim thaum lub sijhawm xuas nrig ntaus, ua kom khoob lossis ua haujlwm drilling.

Daws daws tau:

Koom tes nrog cov chaw tsim khoom laminate thiab qhia tus neeg siv cov khoom ntsuas ua ntej muaj kev hloov pauv rau kev tsim cov laminate.

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

Tiv tauj cov chaw tsim khoom laminate los tshuaj xyuas txhua pawg ntawm cov ntawv ci tooj liab uas tsis dhau qhov kev tshuaj xyuas; Nug kom daws tau qhov tshem tawm cov tshuaj uas pom zoo.

Nug lub chaw tsim khoom laminate rau txoj kev tshem tawm. Feem ntau nws tau pom zoo kom siv cov tshuaj hydrochloric acid, thiab tom qab ntawd tshem nws los ntawm kev siv tshuab sib tsoo thiab txhuam.

Tiv tauj cov chaw tsim khoom laminate kom siv cov txheej txheem tshuaj lossis tshuaj tshem tawm.

Qhia txhua tus neeg ua haujlwm txheej txheem kom hnav hnab looj tes thiab siv tooj liab npog laminate. Ua kom ntseeg tau tias cov laminate tau ua kom zoo lossis ntim rau hauv lub hnab thaum thauj mus los, thiab cov ntsiab lus leej faj ntawm cov ntaub qhwv tau qis, thiab lub hnab ntim khoom tsis muaj av. Ua tib zoo saib xyuas kom tsis muaj ib tus neeg hu rau cov ntawv ci tooj liab thaum siv xab npum uas muaj silicone.
