Tus PCB tooj liab hlau poob tawm (tseem yog xa mus rau cov tooj liab khib nyiab). PCB Factories Txhua tus hais tias nws yog teeb meem laminate thiab yuav tsum tau lawv cov chaw tsim khoom kom ris cov poob tsis zoo.

1. Tus tooj liab ntawv ci yog tshaj-etched. Lub electrolytic ntawv ci siv nyob rau hauv kev ua lag luam feem ntau yog ib leeg-sided tooj liab-plated (feem ntau hu ua liab ntawv ci). Feem ntau pov tooj liab feem ntau yog feem ntau galvanized tooj liab saum toj no 70UM ntawv ci thiab hmoov tshauv tsis muaj pob tooj liab Thaum cov neeg siv hluav taws xob tsim yog qhov zoo dua li cov kab ntawv etching, yog tias lub sij hawm tooj liab nyob tsis tau hloov pauv hauv cov ntawv xov tooj liab tau ntev dhau. Vim tias zinc yog xub thawj cov hlau uas nquag, thaum lub tooj liab hlau ntawm cov kab kev ua kom ntev Ntawd yog, hlau tooj liab ntog tawm. Lwm qhov xwm txheej yog tias tsis muaj teeb meem nrog PCB etching tsis, tab sis tom qab lub etching crying, tus tooj liab xaim kuj tseem nyob ib puag ncig ntawm cov khoom siv etching ntawm PCB nplaim. Yog tias nws tsis ua tiav rau lub sijhawm ntev, nws tseem yuav ua rau sab ntxiv etching ntawm lub tooj liab tooj liab. Pov tooj liab. Qhov xwm txheej no feem ntau yog pom raws li cov kab nyias nyias, lossis thaum lub caij huab cua noo, qhov tsis xws luag yuav tshwm sim ntawm tag nrho PCB. Sawb lub tooj liab hlau kom pom tias cov xim ntawm kev sib cuag nrog lub hauv paus txheej (qhov thiaj li hu ua rougened nto) tau hloov. Cov xim ntawm tus tooj liab ntawv ci yog txawv los ntawm qhov qub tooj liab ntawv ntawv. Tus thawj tooj liab xim ntawm lub hauv qab txheej yog pom, thiab tev lub zog ntawm lub tooj liab ntawv ci ntawm kab tuab kuj yog qhov qub.

2. Kev sib tsoo tau tshwm sim hauv zos hauv PCB cov txheej txheem, thiab lub tooj hlau tooj liab tau sib cais los ntawm cov txheej txheem ntawm cov txheej txheem sab nraud. Qhov kev ua tau zoo no yog qhov chaw ua haujlwm tsis zoo lossis kev taw qhia. Cov hlau liab liab yuav muaj obvious twisting lossis khawb / cuam tshuam cov cim nyob rau hauv tib txoj kev taw qhia. Yog tias koj tev tawm ntawm lub tooj liab tooj liab ntawm cov khoom siv puas thiab saib cov xim ntawm lub tooj liab

3. PCB Circuit Circuit Tsim yog tsis tsim nyog. Yog tias tuab tuab neeg tooj liab ntawv ci yog siv los tsim cov Circuit Court uas yog cov dhau lawm, nws tseem yuav ua rau muaj ntau dhau ntawm cov hluav taws xob thiab kev tsis lees txais.

2. Vim li cas rau Laminate Manufacturing:

Nyob rau hauv ib txwm muaj xwm txheej, ntev li ntev li lub laminate yog kub nias rau ntau tshaj li 30 feeb, yog li cov preprais yuav ua rau muaj kev sib xyaw ua ke ntawm tooj liab lub zog thiab lub substrate hauv lub laminate. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm stacking thiab stacking laminates, yog tias pp yog qhov tsis txaus, tab sis lub tev tooj liab ntawm cov xov tooj liab uas poob ze ntawm cov xov hlau yuav tsis muaj kev phem.

3. Vim li cas rau laminate raw khoom:

1. Raws li tau hais los saum toj no, zoo ib yam electrolytic tooj liab cov ntawv yog txhua yam khoom uas tau ua rau lub galvanized lossis tooj liab. Yog hais tias lub ncov yog txawv txav thaum lub sij hawm ntau lawm ntawv ci, lossis lub plating tshuab ua tsis zoo, ua rau lub tooj liab liab, ua rau lub tooj liab liab, ua rau lub tooj liab liab, ua rau lub tooj liab liab, ua rau lub tooj liab tooj liab ua rau muaj zog. Thaum cov ntawv tsis zoo cov ntawv nias rau hauv PCB thiab ntsaws rau hauv cov hluav taws xob hluav taws xob, lub tooj hlau tooj liab yuav poob tawm vim qhov cuam tshuam ntawm kev quab yuam sab nraud. Qhov no zoo ntawm tooj liab kev zam txim yuav tsis pom tus tooj liab corper kom pom cov ntxhib cov ntawv ci (yog, lub zog ntawm lub zog ci yuav ua tsis tau zoo.

2. Tsis zoo adapt ntawv ntawm tooj liab ntawv ci thiab cob: qee cov laminates nrog cov ntawv tshwj xeeb, yog siv tam sim no vim tias muaj cov sib txawv resin systems. Tus kws kho mob uas siv tau feem ntau yog PN cob, thiab lub resin molecular saw qauv yog yooj yim. Cov degree ntawm crosslinking yog tsawg, thiab nws yog ib qho tsim nyog los siv tooj liab ntawv ci nrog lub ncov tshwj xeeb kom phim nws. Thaum ua laminates, siv cov ntawv xov tooj tooj liab tsis phim cov ntawv cob qhia, ua rau tooj liab hlau-clad hlau los ntawm cov hlau nplaum thaum ntxig.
