1.SMT yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob.Nws yog hu ua nto mount technology (los yog nto mount technology).Nws muab faib ua tsis muaj leads lossis luv leads.Nws yog ib qho khoom siv hluav taws xob uas tau sib sau ua ke los ntawm reflow soldering los yog dip soldering.Technology tseem yog cov tshuab nrov tshaj plaws thiab cov txheej txheem hauv kev lag luam hluav taws xob sib dhos.
Nta: Peb cov substrates tuaj yeem siv rau cov khoom siv hluav taws xob, cov teeb liab kis tau tus mob, cua sov dissipation, thiab kev tsim qauv.
Nta: tuaj yeem tiv taus qhov kub thiab lub sijhawm ntawm kev kho thiab soldering.
Lub flatness ua tau raws li qhov yuav tsum tau ntawm cov txheej txheem tsim khoom.
Haum rau kev ua haujlwm rework.
Haum rau kev tsim cov txheej txheem ntawm substrate.
Tsawg dielectric suav thiab ua haujlwm siab.
Cov khoom siv feem ntau siv rau peb cov khoom lag luam muaj kev noj qab haus huv thiab ib puag ncig tus phooj ywg epoxy resins thiab phenolic resins, uas muaj cov nplaim hluav taws zoo, cov khoom kub, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab cov nqi qis.
Cov lus hais saum toj no yog tias cov tawv tawv substrate yog lub xeev ruaj khov.
Peb cov khoom kuj muaj qhov hloov pauv tau yooj yim, uas tuaj yeem siv los txuag chaw, quav lossis tig, txav, thiab ua los ntawm cov ntawv nyias nyias nyias nrog kev ua haujlwm zoo.
Qhov tsis zoo yog tias cov txheej txheem sib dhos yog qhov nyuaj, thiab nws tsis haum rau kev siv micro-pitch.
Kuv xav tias cov yam ntxwv ntawm lub substrate yog me me ua thiab qhov sib txawv, loj thickness thiab cheeb tsam, zoo thermal conductivity, tougher mechanical zog, thiab zoo stability.Kuv xav tias qhov kev tso kawm technology ntawm lub substrate yog hluav taws xob kev ua tau zoo, muaj kev ntseeg siab, tus qauv qhov chaw.
Peb tsis tsuas yog muaj kev ua haujlwm tsis siv neeg thiab kev sib koom ua ke, tab sis kuj tseem muaj ob qhov kev lees paub ntawm phau ntawv txheeb xyuas thiab kev tshuaj xyuas tshuab, thiab cov khoom dhau ntawm cov khoom yog siab li 99.98%.
2.PCB yog cov khoom siv hluav taws xob tseem ceeb tshaj plaws, thiab tsis muaj leej twg.Feem ntau, cov qauv siv hluav taws xob ua los ntawm cov ntawv luam tawm, cov khoom luam tawm lossis cov khoom sib xyaw ua ke ntawm ob qho ntawm cov khoom siv insulating raws li tus qauv tsim ua ntej hu ua lub tshuab luam ntawv.Cov qauv siv hluav taws xob uas muab hluav taws xob sib txuas ntawm cov khoom ntawm cov khoom siv hluav taws xob yog hu ua cov ntawv luam tawm Circuit Board (los yog cov ntawv luam tawm), uas yog ib qho tseem ceeb ntawm kev txhawb nqa rau cov khoom siv hluav taws xob thiab cov khoom nqa khoom uas tuaj yeem nqa cov khoom.
Kuv xav tias peb feem ntau qhib lub khoos phis tawj keyboard kom pom cov yeeb yaj kiab mos (sleev insulating substrate) luam tawm nrog nyiaj-dawb (nyiaj muab tshuaj txhuam) cov duab kos duab thiab tso duab duab.Vim tias hom qauv no tau txais los ntawm txoj kev tshuaj ntsuam luam ntawv dav dav, peb hu rau lub rooj tsav xwm luam tawm no hloov pauv nyiaj hloov pauv luam tawm Circuit Board.Cov ntawv luam tawm Circuit Board ntawm ntau lub khoos phis tawj motherboard, cov duab kos duab, daim npav network, modems, suab phaib thiab cov khoom siv hauv tsev uas peb pom hauv lub nroog lub computer sib txawv.
Cov khoom siv hauv paus nws siv yog ua los ntawm cov ntawv hauv paus (feem ntau yog siv rau ib sab) lossis iav ntaub puag (feem ntau yog siv rau ob sab thiab ntau txheej), pre-impregnated phenolic lossis epoxy resin, ib sab lossis ob sab ntawm lub ntsej muag. yog pasted nrog tooj liab cladding thiab ces laminated thiab kho ua.Qhov no hom ntawm Circuit Court board tooj liab-clad daim ntawv, peb hu nws ib tug nruj board.Tom qab ua ib lub rooj tsavxwm luam tawm, peb hu nws lub rooj tsavxwm nruj.
Cov ntawv luam tawm Circuit Board nrog cov qauv luam tawm ntawm ib sab yog hu ua ib qho kev sib txuas ntawm ib sab, lub rooj tsav xwm luam tawm nrog cov qauv luam tawm ntawm ob sab, thiab cov ntawv luam tawm Circuit Board tsim los ntawm kev sib txuas ntawm ob sab los ntawm metallization ntawm lub qhov, peb hu nws ob-sided board.Yog tias lub rooj tsavxwm luam tawm nrog ob sab sab hauv txheej, ob txheej txheej txheej ib sab, lossis ob txheej txheej sab hauv thiab ob sab txheej txheej yog siv, qhov chaw thiab cov khoom siv insulating sib txuas ua ke thiab cov ntawv luam tawm. board nrog cov qauv conductive interconnected raws li tus tsim yuav tsum tau ua ib tug plaub-txheej thiab rau-txheej luam Circuit Court board, kuj hu ua ib tug multi-layer luam Circuit Court board.
3.PCBA yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob.PCB mus los ntawm tag nrho cov txheej txheem ntawm nto mount technology (SMT) thiab kev ntxig ntawm DIP plug-ins, uas yog hu ua txheej txheem PCBA.Qhov tseeb, nws yog PCB nrog ib daim txuas.Ib tug yog lub tiav lawm board thiab lwm yam yog lub liab qab board.
PCBA tuaj yeem nkag siab tias yog lub rooj tsav xwm ua tiav, uas yog, tom qab tag nrho cov txheej txheem ntawm lub rooj tsavxwm ua tiav, PCBA tuaj yeem suav.Vim yog qhov txuas ntxiv me me thiab ua kom zoo dua ntawm cov khoom siv hluav taws xob, feem ntau ntawm cov laug cam tam sim no txuas nrog etching resists (lamination lossis txheej).Tom qab raug thiab kev loj hlob, Circuit Court boards yog tsim los ntawm etching.
Yav dhau los, kev nkag siab ntawm kev ntxuav tsis txaus vim qhov sib dhos ntom ntom ntawm PCBA tsis siab, thiab nws kuj tau ntseeg tias cov khoom siv hluav taws xob tsis zoo thiab tsis zoo, thiab yuav tsis cuam tshuam rau kev ua haujlwm hluav taws xob.
Niaj hnub no cov rooj sib tham hauv hluav taws xob zoo li yuav tsum tau ua me me, txawm tias cov khoom siv me me, lossis me me.Cov pins thiab cov ntaub qhwv tau los ze zog dua.Niaj hnub no cov khoob khoob tau me dua thiab me dua, thiab cov khoom paug kuj tseem tuaj yeem daig hauv qhov khoob, uas txhais tau hais tias cov khoom me me, yog tias lawv nyob nruab nrab ntawm ob qhov khoob, kuj yuav yog qhov tshwm sim tsis zoo tshwm sim los ntawm luv luv Circuit Court.
Nyob rau hauv xyoo tas los no, kev lag luam hauv hluav taws xob sib dhos tau paub ntau ntxiv thiab hais txog kev tu, tsis yog rau cov khoom yuav tsum tau ua xwb, tab sis kuj rau ib puag ncig thiab kev tiv thaiv tib neeg kev noj qab haus huv.Yog li ntawd, muaj ntau tus neeg muab khoom siv tu thiab kev daws teeb meem, thiab kev tu vaj tse kuj tau dhau los ua ib qho ntawm cov ntsiab lus tseem ceeb ntawm kev sib pauv thiab kev sib tham hauv kev lag luam hauv hluav taws xob sib dhos.
4. DIP yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob.Nws yog hu ua dual nyob rau hauv-kab ntim tshuab, uas yog hais txog kev sib xyaw ua ke chips uas tau ntim rau hauv ob lub hauv-kab ntim.Daim ntawv ntim no tseem siv tau rau hauv cov khoom siv me me thiab nruab nrab feem ntau., tus naj npawb ntawm pins feem ntau tsis tshaj 100.
CPU nti ntawm DIP ntim tshuab muaj ob kab ntawm tus pins, uas yuav tsum tau muab tso rau hauv lub qhov (socket) nti nrog DIP qauv.
Ntawm chav kawm, nws tseem tuaj yeem muab tso ncaj qha rau hauv lub rooj tsav xwm hauv Circuit Court nrog tib tus lej ntawm cov qhov thiab cov qauv geometric rau soldering.
DIP ntim tshuab yuav tsum tau saib xyuas tshwj xeeb thaum ntxig thiab tshem tawm ntawm lub qhov (socket) nti kom tsis txhob muaj kev puas tsuaj rau cov pins.
Nta: ntau txheej ceramic DIP DIP, ib txheej ceramic DIP DIP, txhuas ncej DIP (xws li iav ceramic sealing hom, yas ntim qauv hom, ceramic low melting iav ntim hom) thiab hais txog.
DIP plug-in yog qhov txuas hauv cov txheej txheem tsim hluav taws xob, muaj cov phau ntawv plug-ins, tab sis kuj AI tshuab plug-ins.Ntxig cov khoom uas tau teev tseg rau hauv txoj haujlwm tshwj xeeb.Los ntawm txhais tes plug-ins kuj yuav tsum mus los ntawm yoj soldering rau solder hluav taws xob Cheebtsam ntawm lub rooj tsavxwm.Rau cov khoom siv ntxig, nws yog ib qho tsim nyog yuav tsum tau xyuas seb lawv puas tau ntxig tsis raug lossis ploj lawm.
DIP plug-in post-soldering yog ib qho tseem ceeb heev hauv kev ua cov pcba thaj, thiab nws cov kev ua tau zoo ncaj qha cuam tshuam rau kev ua haujlwm ntawm pcba board, nws qhov tseem ceeb yog qhov tseem ceeb heev.Tom qab ntawd tom qab soldering, vim qee yam khoom, raws li cov kev txwv ntawm cov txheej txheem thiab cov khoom siv, tsis tuaj yeem soldered los ntawm lub tshuab yoj soldering, thiab tsuas yog ua los ntawm tes.
Qhov no tseem qhia txog qhov tseem ceeb ntawm DIP plug-ins hauv cov khoom siv hluav taws xob.Tsuas yog los ntawm kev them nyiaj mloog mus rau cov ntsiab lus tuaj yeem ua tiav indistinguishable.
Hauv plaub yam khoom siv hluav taws xob loj no, txhua tus muaj nws tus kheej qhov zoo, tab sis lawv sib koom ua ke los tsim cov txheej txheem ntau lawm.Tsuas yog los ntawm kev txheeb xyuas qhov zoo ntawm cov khoom tsim tawm tuaj yeem muaj ntau yam ntawm cov neeg siv khoom thiab cov neeg siv khoom paub txog peb lub hom phiaj.
