PCB hais txog cov ntawv luam tawm Circuit Board (Printed circuit board), uas yog tus muab kev sib txuas hluav taws xob ntawm cov khoom siv hluav taws xob.Nws yog ntau heev nyob rau hauv kev lag luam electronics, thiab peb anti-adhesive (xim) yog dav siv nyob rau hauv nws, thiab tsis muaj xws li hom ntawm nplaum li PCB peb-pov thawj nplaum (xim).Qhov tseeb, ib txheej ntawm peb-pov thawj nplaum (xim) yog coated ntawm PCB.pleev xim).
Kev siv peb cov xim tiv thaiv yog tiv thaiv PCB los ntawm kev puas tsuaj los ntawm lwm yam thiab txhim kho lub neej kev pab cuam ntawm PCB.Raws li cov khoom siv hluav taws xob high-end muaj cov kev xav tau siab dua thiab siab dua rau PCB zoo, cov txheej txheem kev sib raug zoo tau siv dav hauv cov rooj sib tham.
Yam uas yooj yim ua rau PCB puas:
Cov dej noo yog qhov tseem ceeb tshaj plaws thiab muaj kev puas tsuaj loj tshaj plaws rau PCBs.Cov dej noo ntau dhau yuav ua rau txo cov rwb thaiv tsev ntawm cov conductors, nrawm decomposition, txo Q tus nqi, thiab corrode conductors.Nws feem ntau tshwm sim tias cov hlau ntawm PCB muaj patina, uas yog tshwm sim los ntawm cov tshuaj tiv thaiv ntawm cov hlau tooj liab nrog dej vapor thiab oxygen.
Ib yam li kev puas tsuaj yog ntau pua tus kab mob uas koj tuaj yeem pom ntawm random ntawm lub rooj tsav xwm luam tawm, thiab lawv tuaj yeem ua rau cov txiaj ntsig zoo ib yam li ya raws, xws li hluav taws xob tsis ua haujlwm, corrosion ntawm conductors, thiab txawm tias luv luv Circuit Court.Cov pa phem feem ntau pom nyob rau hauv cov tshuab hluav taws xob tej zaum yuav yog cov khoom siv tshuaj lom neeg los ntawm kev tsim khoom.Cov pa phem no muaj xws li fluxes, cov kuab tshuaj tso tawm, cov khoom hlau, thiab cov cim cim.
Tseem muaj cov pab pawg loj ntawm cov pa phem tshwm sim los ntawm tib neeg txhais tes, xws li cov roj hauv lub cev, cov ntiv tes ntiv tes, cov tshuaj pleev ib ce thiab cov khoom noj seem.Kuj tseem muaj ntau cov kuab paug nyob hauv qhov chaw ua haujlwm, xws li tshuaj tsuag ntsev, xuab zeb, roj, kua qaub, lwm yam corrosive chav thiab pwm.
Vim li cas thiaj thov peb cov nplaum nplaum (xim)?
Lub PCB coated nrog peb cov nplaum nplaum (xim) tsis yog tsuas yog dej-pov thawj, plua plav-pov thawj, thiab tsis muaj dej, tab sis kuj muaj kev tiv thaiv txias thiab cua sov, kev laus tsis kam, hluav taws xob tiv thaiv, ntsev tsuag tsis kam, ozone corrosion kuj, kev co. tsis kam, zoo yooj thiab muaj zog adhesion.Thaum cuam tshuam los ntawm qhov tsis zoo ntawm ib puag ncig kev ua haujlwm, nws tuaj yeem txo lossis tshem tawm qhov kev ua haujlwm tsis zoo ntawm hluav taws xob ua haujlwm.
Vim qhov sib txawv daim ntawv thov ib puag ncig ntawm cov khoom kawg sib txawv, qhov kev ua tau zoo ntawm cov nplaum nplaum yuav raug qhia.Cov khoom siv hauv tsev xws li cov tub yees, tshuab ntxhua khaub ncaws, thiab cov cua kub cua sov muaj qhov yuav tsum tau muaj kev tiv thaiv kom tsis txhob ya raws, thaum cov kiv cua sab nraum zoov thiab cov teeb pom kev zoo xav tau cov khoom siv los tiv thaiv huab cua zoo.
Yuav ua li cas sai thiab zoo siv cov nplaum nplaum (xim) rau PCB?
Hauv kev lag luam PCB, muaj cov cuab yeej siv tsis zoo rau txheej tiv thaiv cov xim ntawm cov laug cam - peb lub tshuab pleev xim pleev xim, tseem hu ua peb lub tshuab pleev xim pleev xim, peb cov xim pleev xim pleev xim, peb cov xim pleev xim rau cov roj pleev xim. , peb cov xim pleev xim rau cov xim pleev xim pleev xim, thiab lwm yam, yog tsim los tswj cov kua dej, thiab npog ib txheej ntawm cov xim pleev xim rau ntawm qhov chaw ntawm PCB, xws li npog ib txheej ntawm photoresist ntawm qhov chaw ntawm PCB los ntawm dipping, txau. los yog spin txheej.
Peb lub tshuab pleev xim pleev xim yog tsuas yog siv rau cov tshuaj pleev xim, txheej thiab cov kua nplaum, pleev xim thiab lwm yam kua hauv cov txheej txheem khoom mus rau qhov tseeb ntawm txhua yam khoom, thiab tuaj yeem siv los ua kom tiav kab kos duab, voj voog lossis arc.
Peb lub tshuab pleev xim rau xim yog cov khoom siv tshuaj tsuag tshwj xeeb uas tsim los rau kev txau peb cov xim pleev xim.Txij li cov ntaub ntawv yuav tsum tau txau thiab cov tshuaj tsuag cov kua yuav tsum sib txawv, qhov kev xaiv ntawm lub tshuab txheej txheej ntawm cov khoom siv kuj txawv.Peb lub tshuab pleev xim pleev xim siv lub tshuab siv lub tshuab tswj xyuas qhov tseeb, uas tuaj yeem paub txog peb-axis txuas, thiab tau nruab nrog Lub koob yees duab qhov chaw nrhiav qhov system tuaj yeem tswj tau qhov chaw txau.
