Binyuze mu mwobo uzwi kandi nko mu mwobo.Kugirango wuzuze ibisabwa byabakiriya ,.
ikibaho unyuze mu mwobo ugomba gucomeka.Nyuma yimyitozo myinshi, inzira ya aluminiyumu yamashanyarazi yahinduwe, kandi ikibaho cyumuzunguruko wububiko bwagurishijwe mask na plug byuzuzwa meshi yera.umwobo.Umusaruro uhamye hamwe nubwiza bwizewe.
Binyuze mu mwobo bigira uruhare rwo guhuza no kuyobora imirongo.Iterambere ryinganda za elegitoroniki naryo riteza imbere iterambere rya PCBs, kandi rinashyira imbere ibisabwa cyane kubijyanye n’ikoranabuhanga ryandika ryanditse hamwe n’ikoranabuhanga ryo hejuru.Binyuze mu buhanga bwo gucomeka umwobo, kandi ibisabwa bikurikira bigomba kuba byujujwe icyarimwe:
(1) Hariho umuringa gusa unyuze mu mwobo, kandi mask yo kugurisha irashobora gucomeka cyangwa ntayo;
.
.
Kuki ikibaho cyumuzunguruko cya PCB gikeneye guhagarika vias?
Hamwe niterambere ryibicuruzwa bya elegitoronike mu cyerekezo cy "urumuri, ruto, rugufi na ruto", PCB nazo ziratera imbere zigana ubucucike bukabije kandi bigoye.Kubwibyo, umubare munini wa SMT na BGA PCBs wagaragaye, kandi abakiriya bakeneye gucomeka imyobo mugihe cyo gushiraho ibice, cyane cyane harimo imirimo itanu:
.cyane cyane iyo dushyize umwobo kuri padi ya BGA, tugomba kubanza gukora umwobo, hanyuma ugasiga zahabu kugirango byoroherezwe kugurisha BGA.
(2) Irinde ibisigisigi bya flux mu mwobo;
.
.
(5) Irinde amasaro yamabati gusohoka mugihe cyo kugurisha imiraba, bigatera uruziga rugufi.
Kumenyekanisha Ikoreshwa rya Tekinoroji
Ku mbaho zo hejuru hejuru, cyane cyane kuri BGA na IC gushiraho, kunyura mu mwobo bigomba kuba biringaniye, hamwe na convex hamwe na conve wongeyeho cyangwa ukuyemo mil 1, kandi ntihakagombye kubaho amabati atukura kumpera yumwobo;amabati y'amabati yihishe mu mwobo, kugirango ugere ku kunyurwa kwabakiriya Ibisabwa muburyo bwo gucomeka umwobo birashobora gusobanurwa nkibintu bitandukanye, inzira igenda ni ndende cyane, kandi kugenzura inzira biragoye.Habaho ibibazo nko gutakaza amavuta mugihe cyo gushyushya ikirere gishyushye hamwe nubushakashatsi bwo kurwanya amavuta yicyatsi;guturika amavuta nyuma yo gukira.Noneho ukurikije uko umusaruro wifashe mubyukuri, inzira zinyuranye zicomeka za PCB zavunaguye, kandi kugereranya no gusobanura bimwe mubikorwa, ibyiza nibibi:
Icyitonderwa: Ihame ryakazi ryo kuringaniza ikirere gishyushye nugukoresha umwuka ushyushye kugirango ukureho uwagurishije birenze hejuru yikibaho cyumuzunguruko cyacapwe no mu mwobo, kandi uwagurishije asigaye apfundikirwa neza kuri padi, imirongo yabagurisha idashobora guhangana nubuso gupakira ingingo, nuburyo bwo kuvura hejuru yubuyobozi bwanditse bwumuzingo.imwe.
1. Shira umwobo nyuma yo gushyushya umwuka
Inzira igenda ni: ikibaho cyo kugurisha mask → HAL → gucomeka umwobo → gukiza.Inzira idacomeka ikoreshwa mubikorwa.Nyuma yumwuka ushyushye uringaniye, ecran ya aluminium cyangwa ecran yo guhagarika wino ikoreshwa kugirango urangize unyuze mu mwobo ucomekaho ibihome byose bisabwa n'umukiriya.Irangi ryo gucomeka rishobora kuba wino yunvikana cyangwa wino ya thermosetting.Mugihe cyo kwemeza ibara rimwe rya firime itose, wino yo gucomeka nibyiza gukoresha wino imwe nubuso bwibibaho.Ubu buryo burashobora kwemeza ko kunyura mu mwobo bitagwa amavuta nyuma yumuyaga ushyushye uringaniye, ariko biroroshye gutera wino wacometse wino wanduye hejuru yubuyobozi kandi ntibingana.Biroroshye kubakiriya gutera kugurisha kugaragara (cyane cyane muri BGA) mugihe ugenda.Abakiriya benshi rero ntibemera ubu buryo.
2. Shira umwobo mbere yo gushyushya umwuka
2.1 Koresha urupapuro rwa aluminiyumu kugirango ucomeke umwobo, ukize, kandi usya isahani yo kwimura icyitegererezo
Muri ubu buryo, imashini yo gucukura ya CNC ikoreshwa mu gusohora urupapuro rwa aluminiyumu rugomba gucomeka, gukora isahani ya ecran, no gucomeka umwobo kugira ngo umenye ko unyuze mu mwobo wuzuye, kandi wino yo gucomeka ikoreshwa mu gucomeka umwobo ., resin kugabanuka kugabanuka ni nto, kandi imbaraga zo guhuza urukuta rwumwobo nibyiza.Inzira igenda ni: kwiyitirira → gucomeka umwobo → gusya isahani transfer uburyo bwo kwimura → guterana → ikibaho cyo kugurisha mask
Ubu buryo bushobora kwemeza ko unyuze mu mwobo ucometse, kandi ikirere gishyushye ntikizagira ibibazo byiza nko guturika kwa peteroli no gutakaza amavuta ku nkombe y’umwobo, ariko iki gikorwa gisaba umubyimba umwe w’umuringa, kugirango umubyimba wumuringa wurukuta rwumwobo urashobora kuba wujuje ubuziranenge bwabakiriya.Kubwibyo, ibisabwa kugirango umuringa ushyire ku isahani yose ni muremure cyane, kandi hari n’ibisabwa cyane kugirango imikorere yimashini isya kugirango ibisigara hejuru yumuringa bivaneho burundu, kandi hejuru yumuringa hasukuye kandi nta buntu umwanda.Inganda nyinshi za PCB ntizifite inshuro imwe yumubyimba wumuringa, kandi imikorere yibikoresho ntabwo yujuje ibyangombwa, bigatuma iyi nzira idakoreshwa cyane muruganda rwa PCB.
2.2 Nyuma yo gucomeka umwobo hamwe namabati ya aluminium, banza ugaragaze mask yagurishijwe hejuru yubuyobozi
Muri ubu buryo, imashini yo gucukura ya CNC ikoreshwa mu gusohora urupapuro rwa aluminiyumu rugomba gucomeka kugira ngo rukore icyapa cya ecran, gishyirwa ku mashini icapa ecran yo gucomeka.Amacomeka amaze kurangira, ntagomba guhagarara muminota irenga 30.Inzira igenda ni: kwitegura - gucomeka umwobo - ecran ya silike - mbere yo guteka - kwerekana - gutera imbere - gukiza
Iyi nzira irashobora kwemeza ko unyuze mu mwobo utwikiriwe neza na peteroli, umwobo ucomeka neza, kandi ibara rya firime itose ni kimwe.Amapadi, bivamo kugurishwa nabi;nyuma yumuyaga ushyushye uringaniye, inkombe zinyuze mu mwobo hamwe namavuta.Biragoye kugenzura umusaruro ukoresheje ubu buryo, kandi injeniyeri yubushakashatsi agomba gufata inzira zidasanzwe hamwe nibipimo kugirango yizere ubwiza bwumwobo.
Kuki ikibaho cyumuzunguruko cya PCB gikeneye guhagarika vias?
2.3 Nyuma yuko urupapuro rwa aluminiyumu rucomeka umwobo, rugatera imbere, rukiza, kandi rugasya ikibaho, ubuso bwibibaho buragurishwa.
Koresha imashini ya CNC yo gucukura kugirango usohore urupapuro rwa aluminiyumu rusaba gucomeka, gukora isahani ya ecran, hanyuma ubishyire kumashini icapura imashini ihindura imashini.Amacomeka agomba kuba yuzuye, kandi impande zombi zirasohoka.Inzira igenda ni: mbere yo kuvura - gucomeka umwobo - mbere yo guteka - iterambere - mbere yo gukiza - ikibaho cyo kugurisha mask
Kuberako iyi nzira ifata plug-umwobo ukiza kugirango unyuze mu mwobo utazabura amavuta cyangwa ngo uturike amavuta nyuma ya HAL, ariko nyuma ya HAL, biragoye gukemura burundu ikibazo cyamasaro yamabati mumwobo na tin kumwobo unyuze, abakiriya benshi rero ntibabyemera.
2.4 Mask yo kugurisha hejuru yubuyobozi hamwe nu mwobo wacometse icyarimwe.
Ubu buryo bukoresha mesh ya 36T (43T) ya mesh, yashizwe kumashini icapura ecran, ukoresheje isahani yinyuma cyangwa uburiri bwimisumari, hanyuma ugacomeka inzira zose ukoresheje umwobo mugihe urangije hejuru yubuyobozi.Inzira igenda ni: kwiyitirira - gucapa ecran- -Gutegura-guteka - Kumurika - Iterambere - Umuti
Ubu buryo bufite igihe gito nigipimo kinini cyo gukoresha ibikoresho, gishobora kwemeza ko kunyura mu mwobo bitazabura amavuta kandi unyuze mu mwobo ntuzabikwa nyuma yo gushyushya ikirere., Umwuka uraguka kandi ucamo masike yabagurishije, bigatera ubusa nuburinganire.Hazabaho umubare muto unyuze mu mwobo uhishe mumabati mugihe ikirere gishyushye.Kugeza ubu, isosiyete yacu yakemuye ahanini umwobo nuburinganire bwuyobowe nu mwobo nyuma yubushakashatsi bwinshi, ihitamo ubwoko butandukanye bwa wino nubukonje, ihindura umuvuduko wogucapisha ecran ya silike, nibindi, kandi ubu buryo bwakoreshejwe muburyo bwo gukora cyane. .
