Lub tshuab hluav taws xob ntawm lub dav hlau ntsib teeb meem kev ruaj ntseg hauv qhov chaw hluav taws xob ib puag ncig. Raws li cov tub ntxhais cab kuj rau cov teeb liab kis tau tus mob thiab cov khoom sib txuas ntawm cov khoom siv hluav taws xob, cov ntawv luam tawm Circuit Court boards hluav taws xob tiv thaiv yog ncaj qha ntsig txog qhov ua tau zoo ntawm qhov chaw ua haujlwm. Txhawm rau kom ntseeg tau tias kev lag luam txhim khu kev qha ntawm PCBs nyob rau hauv huab cua huab cua puag ncig hauv qhov chaw, kev lag luam tau tsim qhov chaw hluav taws xob hluav taws xob tiv thaiv PCB cov qauv, uas suav nrog kev xaiv cov khoom siv, ntsuas kev ua tau zoo, kev txheeb xyuas ntau lawm, thiab lwm yam, tsim kom muaj kev tswj hwm nruj thiab muaj kev lav phib xaub rau cov khoom siv hluav taws xob hauv aerospace.
1, Lub hauv paus tseem ceeb rau kev tsim qauv
Txoj kev loj hlob ntawm qhov chaw hluav taws xob tiv thaiv pcb cov qauv yog ua raws li kev nkag siab tob ntawm qhov chaw hluav taws xob ib puag ncig. Muaj ntau hom hluav taws xob hauv qhov chaw uas tuaj yeem muaj ntau yam cuam tshuam rau cov ntawv luam tawm hauv Circuit Court boards, suav nrog cov teeb liab cuam tshuam, kev ua haujlwm tsis zoo ntawm cov khoom siv hluav taws xob, hluav taws xob tsis ua haujlwm, thiab kev puas tsuaj mus tas li. Yog li ntawd, lub hom phiaj tseem ceeb ntawm tus qauv yog los tiv thaiv ntau yam hluav taws xob thiab ua kom ntev - lub sij hawm ruaj khov. Ua ke nrog qhov sib txawv ntawm cov hluav taws xob siv hluav taws xob sib txawv ntawm lub luag haujlwm sib txawv ntawm lub dav hlau, cov hluav taws xob tiv thaiv qib ntawm cov ntawv luam tawm Circuit Board hauv cov ntawv thov sib txawv tau txhais kom meej meej kom paub meej tias tus qauv npog ob qho tib si cov kev cai thiab yoog raws li lub hom phiaj tshwj xeeb.
2, Core technical indicators, As
Lub hauv paus tseem ceeb ntawm qhov chaw hluav taws xob hluav taws xob tiv thaiv pcb tus qauv yog ob qho kev txwv nruj ntawm cov khoom siv thiab kev ua haujlwm, thiab txhua qhov ntsuas tau raug txheeb xyuas los ntawm qhov chaw ib puag ncig simulation kev sim kom ntseeg tau tias muaj kev ntseeg siab ntawm kev siv tswv yim.
Nyob rau hauv cov nqe lus ntawm kev xaiv cov khoom, cov qauv muab cov kev xav tau meej rau cov khoom tseem ceeb xws li pcb substrate, tooj liab ntawv ci, solder mask, thiab lwm yam. Lub substrate yuav tsum tau ua los ntawm cov khoom uas tsis muaj poob thiab siab stability composite cov ntaub ntawv kom muaj kev ruaj ntseg nyob rau hauv huab cua kub ntau yam thiab tiv thaiv molecular saw breakage los ntawm hluav taws xob; Cov ntawv ci tooj liab yuav tsum yog hom purity siab, nrog rau qhov sib txawv ntawm thickness tswj kom tsis txhob muaj qhov tsis sib xws tam sim no thiab kev puas tsuaj hauv zos overheating los ntawm qhov tsis sib xws.
Nyob rau hauv cov nqe lus ntawm hluav taws xob tiv thaiv kev ua tau zoo, tus qauv teeb tsa ob qhov tseem ceeb tsis: ib qho yog tag nrho cov koob tshuaj tiv thaiv kab mob, uas yog cov koob tshuaj tiv thaiv hluav taws xob uas pcb tuaj yeem tiv taus thoob plaws lub voj voog ua haujlwm; Qhov thib ob yog ib qho kev cuam tshuam ib puag ncig, uas yog siv los ntsuas lub peev xwm ntawm pcb los tiv thaiv siab - lub zog hnyav ion cuam tshuam, txhawm rau kom ntseeg tau tias pcb tswj cov teeb liab kis tau tus mob thiab kev ua haujlwm zoo hauv cov hluav taws xob hnyav.
Tsis tas li ntawd, tus qauv tseem tso tawm cov kev xav tau ntxiv rau kev ua haujlwm ntawm cov tshuab thiab hluav taws xob ntawm cov ntawv luam tawm Circuit Board. Nyob rau hauv cov nqe lus ntawm machinery, nws yog tsim nyog los xyuas kom meej lub zog dabtsi yog khoov ntawm lub pcb, tswj lub thermal expansion coefficient kom phim lub structural Cheebtsam ntawm lub spacecraft, thiab tsis txhob muaj kev nyuaj siab los ntawm qhov kub thiab txias hloov ua rau pcb cracking; Hais txog hluav taws xob, nws yog ib qho tsim nyog los tswj tus nqi dielectric tangent kom ntseeg tau tias muaj kev tiv thaiv hluav taws xob, tswj kev ncaj ncees ntawm qhov ntev - kis tau tus mob, thiab txo cov teeb liab attenuation thiab cuam tshuam.
3, Ntau lawm thiab kuaj cov qauv
Qhov chaw qib hluav taws xob tiv thaiv pcb tus qauv khiav los ntawm tag nrho cov txheej txheem tsim khoom thiab kev sim, kom ntseeg tau tias lub Hoobkas pcb ua tau raws li tus qauv yuav tsum tau los ntawm kev tswj cov txheej txheem nruj thiab ntau qhov kev txheeb xyuas.
Nyob rau hauv cov txheej txheem ntau lawm, tus qauv qhia cov txheej txheem refined specifications. Piv txwv li, tswj qhov drilling raug ntawm pcb kom tsis txhob muaj kev sib cuag tsis zoo ntawm cov khoom siv pins thiab cov ntaub qhwv los ntawm kev sib txawv ntawm qhov aperture; Xyuas kom muaj kev sib faib ntawm tooj liab txheej thickness thaum lub sij hawm electroplating txheej txheem, tswj qhov saum npoo roughness, thiab tiv thaiv cov ntsiab lus tsis muaj zog ntawm hluav taws xob tawm tsam los ntawm txheej txheej; Lub npog ntsej muag lub ntsej muag siv cov txheej txheem tshwj xeeb los tswj cov tuab thiab tsis txhob muaj qhov tsis xws li npuas thiab pinholes, txhawm rau xyuas kom meej tias lub npog ntsej muag cais tawm hluav taws xob thiab ya raws los ntawm corroding lub hauv Circuit Court ntawm pcb. Nyob rau tib lub sijhawm, qhov chaw tsim khoom yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua kom huv huv, tswj cov ntsiab lus ntawm cov plua plav hauv huab cua, thiab zam cov plua plav adhesion cuam tshuam rau pcb kev ua haujlwm.
Hauv theem kev sim thiab pov thawj, ntau- qhov ntsuas qhov ntsuas qhov ntsuas thiab tag nrho cov xwm txheej tau tsim ua raws li cov qauv, suav nrog ntau yam xws li hluav taws xob kev ua tau zoo, kev hloov pauv ib puag ncig, thiab kev ntseeg siab ntev ntev. Kev ntsuas hluav taws xob yuav tsum tau ua nyob rau hauv ib lub chaw kuaj hluav taws xob simulation, simulating tag nrho cov koob tshuaj hluav taws xob thiab ib qho kev cuam tshuam los ntawm cov khoom siv tshwj xeeb, thiab saib xyuas cov kev hloov pauv hauv pcb hluav taws xob tsis nyob rau lub sijhawm kom paub meej tias cov ntsuas tau ua raws li cov qauv; Environmental adaptability xeem muaj xws li kub thiab tsis kub cycling, kub poob siab, vibration shock, thiab lwm yam., los xyuas kom meej qhov kev ua tau zoo stability ntawm pcb nyob rau hauv huab ib puag ncig tej yam kev mob; Kev ntsuas kev ntseeg tau ntev ntev yuav tsum tau tso lub pcb rau hauv chav kuaj sim uas simulates qhov chaw ib puag ncig thiab ua haujlwm tsis tu ncua txhawm rau txheeb xyuas nws qhov kev ua tau zoo nyob rau lub sijhawm ntev - kev pabcuam.
4, Daim ntawv thov tus nqi ntawm cov qauv
Kev siv ntawm qhov chaw qib hluav taws xob tiv thaiv pcb cov qauv muab kev txhawb nqa tseem ceeb rau kev txhim kho kev lag luam aerospace. Ntawm qhov tod tes, standardizing kev lag luam cov ntsiab lus thiab cov yuav tsum tau rau qhov chaw nyob rau hauv qib luam Circuit Court boards yuav zam tsis tau cov khoom zoo sib txawv los ntawm inconsistent enterprise technical qauv thiab txo qhov kev xaiv ntawm spacecraft electronic systems; Ntawm qhov tod tes, cov kev taw qhia ntawm cov qauv txhawb kev txhim kho thev naus laus zis ntawm kev lag luam pcb, ua rau cov lag luam nce lawv cov kev tshawb fawb thiab kev tsim peev hauv cov khoom siv hluav taws xob tshiab thiab cov txheej txheem ua kom zoo dua qub, txhawb kev loj hlob ntawm cov cuab yeej tshiab, thiab ntxiv dag zog rau kev tiv thaiv hluav taws xob thiab kev koom ua ke ntawm cov ntawv luam tawm Circuit Board.
