Luam Circuit Board (PCB) luv rau Printed Circuit Board. Feem ntau hauv cov khoom siv rwb thaiv tsev, raws li kev tsim ua ntej, ua los ntawm cov ntawv luam tawm, luam tawm cov khoom lossis ua ke ntawm ob qho tib si cov duab kos npe hu ua luam tawm Circuit. Cov duab hluav taws xob ntawm cov hluav taws xob sib txuas ntawm cov khoom siv tau muab rau hauv cov insulating substrate hu ua luam tawm Circuit. Ua li no, daim ntawv luam tawm lossis kab ntawv luam tawm ntawm lub rooj tsav khoom tiav tau hu ua luam tawm Circuit board, tseem hu ua daim txiag luam ntawv lossis luam tawm Circuit board.

PCB yog qhov tsis tseem ceeb rau yuav luag txhua yam khoom siv hluav taws xob peb tuaj yeem pom, los ntawm cov khoom siv hluav taws xob saib, lub laij lej thiab cov khoos phis tawj dav dav rau khoos phis tawj, kev sib txuas lus cov cuab yeej hluav taws xob thiab cov cuab yeej siv tub rog. Tsuav tsis muaj cov khoom siv hluav taws xob xws li kev sib xyaw ua ke, PCB tau siv rau kev sib txuas hluav taws xob ntawm lawv. Nws muab cov cuab yeej txhawb nqa rau kev sib dhos ruaj khov ntawm ntau yam khoom siv hluav taws xob xws li kev sib txuas ua ke, paub txog kev txuas thiab hluav taws xob txuas lossis hluav taws xob rwb thaiv tsev ntawm ntau yam khoom siv hluav taws xob xws li kev sib txuas ua ke, thiab muab cov hluav taws xob xav tau, xws li yam ntxwv tsis zoo, thiab lwm yam. los muab cov kab hluav taws xob thaiv tsis siv neeg; Muab cov cim cim thiab cov duab rau kev teeb tsa, tshuaj xyuas thiab kho.

PCBS ua li cas? Thaum peb qhib tus ntiv tes xoo ntawm lub khoos phis tawj lub hom phiaj, peb tuaj yeem pom cov zaj duab xis mos (hloov tau yooj yim insulating substrate) luam tawm nrog nyiaj-dawb (nyiaj muab tshuaj txhuam) ua cov duab ua duab thiab muaj peev xwm ua tau. Vim tias txoj hauv kev luam ntawv dav dav kom tau txais daim duab no, yog li peb hu rau daim ntawv luam tawm Circuit board no hloov pauv tau cov nyiaj muab tshuaj luam tawm Circuit Board. Sib txawv los ntawm cov niam ntawv, daim npav duab, daim npav network, modems, daim npav suab thiab cov ntawv luam tawm Circuit Court ntawm cov khoom siv hauv tsev peb pom hauv Computer City. Cov khoom siv hauv paus yog siv los ntawm cov ntawv hauv paus (feem ntau yog siv rau ib sab) lossis iav daim ntaub puag (feem ntau siv rau ob sab thiab ntau txheej), ua ntej tsis tau muab tshuaj phenolic lossis epoxy cob ua ntej, ib lossis ob sab ntawm cov nplaim nplaum nrog phau ntawv tooj liab thiab tom qab ntawd laminated kho. Lub rooj sib tham zoo li no npog cov ntawv tooj liab tooj liab, peb hu nws ua pawg nruj. Tom qab ntawd peb ua cov ntawv luam tawm Circuit Board, peb hu nws ua cov ntawv luam tawm Circuit Board nruj. Ib daim ntawv luam tawm Circuit Board nrog cov ntawv luam tawm Circuit ntawm ib sab yog hu ua ib leeg-sab luam tawm Circuit board, thiab daim ntawv luam tawm Circuit board nrog luam tawm cov duab hluav taws xob ntawm ob sab yog sib cuam tshuam ntawm ob sab los ntawm cov hlau ua haujlwm ntawm qhov, thiab peb hu nws ua ob npaug -paub. Yog tias siv ob txheej txheej, ob txoj hauv kev rau txheej txheej lossis ob txheej ob txheej, ob txheej ntawm ib txheej txheej ntawm cov ntawv luam tawm hauv Circuit Court, dhau los ntawm txoj haujlwm tso rau thiab hloov cov rwb thaiv tsev cov ntaub ntawv nplaum thiab cov duab sib txuas ua ke raws li tsim qhov xav tau ntawm luam tawm Circuit pawg thawj coj ua plaub, rau txheej txheej luam tawm Circuit board, tseem hu ua multilayer luam tawm Circuit Board. Tam sim no muaj ntau dua 100 txheej ntawm cov tswv yim luam tawm Circuit board.

Peb daim npav lub rooj siv computer feem ntau yog siv daim iav epoxy iav ob npaug rau ob sab luam tawm Circuit Board, uas muaj ib sab tau tso cov khoom sib txuas thiab lwm sab yog cov tivthaiv ko taw vuam saum npoo, tuaj yeem pom tias cov pob qij txha txuas tau zoo li qub, tivthaiv ko taw tsis sib txuas nto ntawm cov pob qij txha txuas peb hu nws lub ncoo. Vim li cas ho tsis lwm cov xov tooj tooj liab muaj cov tin rau lawv? Vim tias ntxiv rau cov phaj phom thiab lwm qhov ntawm qhov xav tau rau kev siv dag zog, tas li ntawm qhov saum npoo muaj txheej txheej nthwv dej tsis kam vuam zaj duab xis. Nws cov yeeb yaj kiab saum npoo feem ntau yog ntsuab, thiab ob peb siv daj, dub, xiav, thiab lwm yam. Nws txoj haujlwm yog txhawm rau tiv thaiv nthwv dej vuam choj tshwm sim, txhim kho vuam zoo thiab txuag cov laug thiab lwm yam. Nws kuj tseem yog txheej txheem tiv thaiv ruaj khov ntawm cov ntawv luam tawm, tuaj yeem ua lub luag haujlwm ntawm kev ya raws, xeb, kab mob me me thiab kev ua haujlwm puas. Los ntawm sab nraud, qhov saum npoo yog du thiab ci ntsuab thaiv cov yeeb yaj kiab, uas yog qhov ntxim nyiam rau zaj duab xis phaj thiab cua sov kho cov roj ntsuab. Tsis yog tsuas yog cov tsos zoo dua, nws yog ib qho tseem ceeb uas cov ntaub ntawv raug siab yog siab, yog li txhawm rau txhim kho kev ntseeg tau ntawm cov khoom siv sib txuas.

Raws li peb tuaj yeem pom los ntawm lub khoos phis tawj tswj hwm, cov khoom siv tau teeb tsa hauv peb txoj hauv kev. Cov txheej txheem teeb tsa txuas rau kev xa mus uas cov khoom siv hluav taws xob tau tso rau hauv qhov hla ntawm lub tshuab luam ntawv Circuit Board. Nws yog qhov yooj yim kom pom tias ob npaug ntawm ob sab luam tawm lub rooj tsav xwm hauv Circuit Court los ntawm qhov yog raws li hauv qab no: ib qho yog ib qho yooj yim tivthaiv ntxig qhov; Qhov thib ob yog kev tiv thaiv kev tiv thaiv thiab ob tog sib txuas ua ke los ntawm lub qhov; Peb yog ib qho yooj yim ob tog los ntawm qhov; Plaub yog lub hauv paus phaj teeb tsa thiab muab tso rau qhov. Lwm qhov kev teeb tsa thib ob yog kev teeb tsa saum npoo thiab nti ncaj ncaj. Qhov tseeb, nti txuas ncaj qha thev naus laus zis tuaj yeem suav tias yog ib ceg ntawm kev siv tshuab thev naus laus zis, nws yog cov nti ncaj qha rau ntawm daim ntawv luam tawm, thiab tom qab ntawd txuas nrog lub rooj tsav xwm luam tawm los ntawm txoj kev siv hlau txuas lossis siv txoj siv thauj khoom, txoj kev ntxeev, nqaj hlau txoj kev thiab lwm yam ntim tshuab. Qhov vuam nto yog nyob ntawm qhov chaw tivthaiv.

Kev siv tshuab ntom ntom ntom ntom muaj qhov zoo hauv qab no:

(1) Vim tias qhov loj dhau los ntawm lub qhov lossis faus qhov sib txuas sib txuas thev naus laus zis feem ntau raug tshem tawm los ntawm cov ntawv luam tawm, cov xov hluav taws xob ntom ntom ntawm lub rooj tsav xwm tau luam tawm tau zoo dua, thaj chaw ntawm pawg thawj coj saib tau raug txo qis (feem ntau yog ib feem peb ntawm kev teeb tsa ntsaws ), thiab tus lej ntawm cov txheej txheem tsim thiab tus nqi ntawm pawg thawj coj saib kuj tseem tuaj yeem txo qis.

(2) Txo qhov hnyav, txhim kho kev ua haujlwm seismic, kev siv colloidal solder thiab thev naus laus zis thev naus laus zis tshiab, txhim kho cov khoom lag luam zoo thiab ntseeg tau.

(3) Vim tias qhov nce ntawm cov kab hluav taws xob ntom ntom ntom ntom ntom ntom thiab ua kom ntev, cov kab mob muaj zog thiab cov kab mob sib kis tau raug txo qis, uas yog qhov muaj txiaj ntsig zoo los txhim kho cov hluav taws xob tsis ntawm cov ntawv luam tawm.

(4) Nws yooj yim dua kom paub siv lub tshuab ua haujlwm zoo dua li kev teeb tsa ntsaws, txhim kho kev teeb tsa nrawm thiab ua haujlwm tau zoo, thiab txo nqi sib dhos raws li.

Raws li tuaj yeem pom los ntawm cov thev naus laus zis kev nyab xeeb saum toj no, kev txhim kho cov thev naus laus zis hauv tshuab hluav taws xob tau txhim kho nrog kev txhim kho cov ntim ntim tshuab thiab tshuab thev naus laus zis. Lub khoos phis tawj tswj hwm lub computer uas peb pom tam sim no daim npav nws cov nplaum nto teeb tsa tus nqi kom nce mus tsis tu ncua. Qhov tseeb, hom phiaj siv hluav taws xob no rov qab siv lub vijtsam luam ntawv kab duab kab ntawv tsis tuaj yeem ua tau raws li kev xav tau. Yog li ntawd, qhov zoo tib yam kev ua haujlwm siab hauv Circuit Court board, nws cov kab duab thiab cov duab vuam siv yog cov hauv paus txheej txheem nkag tau yooj yim thiab cov txheej txheem tsim cov roj ntsuab ntsuab.

Nrog rau kev txhim kho kev hloov pauv ntawm cov khoom siv hluav taws xob siab, cov khoom lag luam tsim khoom ntawm Circuit Board tau dhau los ua siab dua. Ntau thiab ntau cov thev naus laus zis tshiab tau siv rau kev tsim khoom ntawm lub rooj tsav xwm hauv Circuit Court, xws li tshuab thev naus laus zis, duab hluav taws xob thiab lwm yam. Cov lus saum toj no tsuas yog qee qhov qhia txog ntawm qhov saum npoo, muaj ntau yam hauv kev tsim khoom ntawm lub rooj tsav xwm hauv Circuit Court vim qhov chaw txwv, xws li qhov muag tsis pom qhov, lub rooj sib dhos winding, teflon board, photolithography thiab lwm yam. Yog tias koj xav kawm tob, koj yuav tsum ua haujlwm hnyav.
