PCB number case hais txog lub tshuab luam ntawv (luam tawm hauv Circuit Court board, hu ua PCB) ntawm tus lej, tus yam ntxwv tseem ceeb ntawm tus number case yog viscosity, thixotropy, thiab qhov ua tau zoo. Cov peev txheej ntawm lub cev no yuav tsum tau paub txhawm rau txhim kho kev muaj peev xwm siv tus lej.

Cov yam ntxwv ntawm tus cwj mem PCB

1. Viscosity thiab thixotropy

Hauv txheej txheem txheej txheem tsim khoom lag luam luam ntawv, tshuaj ntsuam luam ntawv yog ib qho ntawm cov txheej txheem tseem ceeb uas tsis tseem ceeb. Txhawm rau kom tau txais kev ncaj ncees ntawm kev tsim cov duab, tus number case yuav tsum muaj viscosity zoo thiab haum thixotropy. Qhov hu ua viscosity yog kev sib txhuam sab hauv ntawm cov kua, uas txhais tau hais tias nyob rau hauv kev nqis tes ua ntawm sab nraud quab yuam, ib txheej ntawm cov kua swb rau lwm txheej ntawm kua, thiab kev sib txhuam quab yuam los ntawm txheej sab hauv ntawm cov kua. Cov kua ua kua sab hauv txheej zawv zawg tau ntsib ntau dua cov neeg ua haujlwm tsis kam, cov kua ua kom tsis haum yog tsawg dua. Viscosity yog ntsuas hauv pas dej. Tshwj xeeb, nws yuav tsum tau sau tseg tias qhov kub tau muaj qhov cuam tshuam rau viscosity.

Thixotropy yog lub cev lub cev ntawm cov kua, uas yog, viscosity ntawm cov kua txo qis hauv kev ntxhov siab, thiab sai sai rov qab rau nws qhov qub viscosity tom qab sawv. Los ntawm kev nplawm, kev ua thixotropic kav ntev txaus kom rov txhim kho nws cov qauv sab hauv. Txhawm rau ua kom muaj txiaj ntsig zoo ntawm kev tshuaj ntsuam luam ntawv, tus lej thixotropy tseem ceeb heev. Tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem scraper, tus number case tau do thiab tom qab ntawd ua rau nws cov kua. Lub luag haujlwm no ua kom tus lej nrawm dua los ntawm qhov nrawm nrawm, txhawb nqa txoj kab qub cais cov lej sib npaug sib npaug rau hauv ib qho. Thaum lub scraper nres txav mus, tus number case rov qab mus rau lub xeev zoo li qub, thiab nws cov viscosity sai rov qab mus rau thawj cov ntaub ntawv xav tau.

2. Ntsig

Cov xim thiab cov ntxhia ntxhia feem ntau yog khov, ua kom zoo rau qhov me me ntawm qhov tsis ntau tshaj 4/5 micron, thiab tsim kom muaj lub xeev sib xws hauv ib daim ntawv. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau siv tus lej zoo.

Hom PCB number case

PCB tus lej feem ntau muab faib ua peb kab, thaiv qhov vuam, cim tus cim peb yam.

Kab number case yog siv los ua txheej txheej txheej txhawm rau tiv thaiv kev xeb ntawm kab thaum kos los tiv thaiv kab, feem ntau yog cov kua ua kua. Muaj ob hom kua qaub tsis kam tiv taus thiab alkaline corrosion tsis kam, alkali tsis kam yog kim dua, txheej txheej ntawm tus lej hauv kev txhuam ntawm kab siv alkali kom yaj nws.

Cov xim zas xim tau pleev xim rau ntawm kab ua kab tiv thaiv tom qab kab. Muaj cov kua hluav taws xob ua kom sov thiab ua kom sov sov, thiab hom tawv tawv ultraviolet, khaws lub ncoo ntawm lub rooj tsavxwm, yooj yim txuas cov khoom, rwb thaiv tsev, thiab tiv taus oxidation.

Tus cwj mem cwj mem tau siv los ua cov cim saum npoo av, xws li kos cim cov cim cim, feem ntau yog dawb.

Qhov tseeb, muaj lwm cov inks, xws li tev tus number case, yog ua tooj liab plating lossis kho saum npoo tsis tas yuav cuam tshuam nrog ib feem ntawm kev tiv thaiv, thiab tom qab ntawd tuaj yeem ntuag tawm; Nyiaj xim thiab lwm yam.

PCB number case siv teeb meem xav tau kev saib xyuas

Raws li qhov kev paub dhau los ntawm kev siv tus lej los ntawm cov tuam ntxhab feem ntau, kev siv tus lej yuav tsum tau ua raws li cov cai hauv qab no:

1. Txawm li cas los xij, qhov ntsuas kub ntawm tus lej yuav tsum khaws cia qis dua 20-25 ℃, kev hloov pauv kub tsis tuaj yeem loj dhau, txwv tsis pub, nws yuav cuam tshuam qhov viscosity ntawm tus number case thiab tshuaj ntsuam luam ntawv zoo thiab cuam tshuam.

Tshwj xeeb tshaj yog thaum tus cwj mem khaws cia sab nraum zoov lossis khaws cia ntawm qhov kub sib txawv, nws yuav tsum tau muab tso rau hauv qhov kub ib puag ncig kom hloov pauv mus rau ob peb hnub lossis ua kom lub raj mis ua kom tiav qhov ntsuas kub tsim nyog. Qhov no yog vim tias siv tus lej txias yuav ua rau lub vijtsam luam ntawv tsis ua tiav, ua rau muaj teeb meem tsis tsim nyog. Yog li ntawd, txhawm rau tswj hwm tus lej zoo, nws yog qhov zoo tshaj los khaws lossis khaws cia hauv cov txheej txheem ntsuas kub ib txwm muaj.

2. Ua ntej siv, tus number case yuav tsum tau ua tiav thiab ua tib zoo siv tus kheej lossis kho tshuab kom sib npaug. Yog tias tus number case mus rau saum huab cua, siv kom sawv ntsug rau ib lub sijhawm. Yog tias yuav tsum tau dilution, sib tov ua ntej ua ntej thiab tom qab ntawd ntsuas qhov viscosity. Cov kua mem yuav tsum raug kaw tam sim tom qab siv. Nyob rau tib lub sijhawm, tsis txhob muab lub vijtsam tso rov qab rau hauv lub raj mis thiab tsis siv tus lej sib xyaw ua ke.

3. Tus neeg saib xyuas kev tu tsev uas tau siv qhov kev hloov pauv tau zoo dua lees paub qhov tseeb, thiab xav kom huv heev. Thaum ntxuav dua, nws yog qhov zoo tshaj los siv cov kuab tshuaj huv.

4. Ink kom qhuav, yuav tsum muaj lub tshuab tso pa tawm zoo hauv lub cuab yeej.

5. Txhawm rau tswj hwm kev ua haujlwm yuav tsum ua kom tau raws li qhov xav tau ntawm chaw ua haujlwm rau kev tshuaj ntsuam luam ntawv.
