Hauv kev tshawb nrhiav roj, txhua qhov kev tshawb nrhiav pom tseeb ntawm cov peev txheej hauv av yog nyob ntawm kev ua haujlwm ruaj khov ntawm cov cuab yeej thiab cov cuab yeej siv hauv qhov chaw huab cua. Nyob rau hauv qhov sib sib zog nqus pom qhov xwm txheej, qhov kub thiab txias feem ntau nyob rau theem siab heev, thiab cov khoom siv hluav taws xob zoo tib yam muaj teeb meem xws li kab laus, teeb liab distortion, thiab kev ua haujlwm tsis ua haujlwm hauv ib puag ncig. Txawm li cas los xij, siab -kub tiv thaiv pcb boards rau cov cuab yeej tshawb nrhiav roj av tau dhau los ua cov neeg nqa khoom tseem ceeb rau kev ua kom ntseeg tau cov ntaub ntawv tshawb pom tseeb thiab cov khoom siv txuas ntxiv mus. Raws li kev lag luam PCB kev lag luam, peb tau koom nrog kev ua haujlwm siab ntawm - kub resistant board processing, thiab nrog cov cuab yeej paub tab thiab kev tswj xyuas nruj, peb tau tsim "siab- tiv thaiv qhov kub thiab txias" rau cov cuab yeej tshawb nrhiav roj av.
1, Kev pom zoo rau kev thov: Cov kev cai tshwj xeeb rau siab -cov pcb boards nyob rau hauv kev tshawb nrhiav roj
Qhov chaw ua haujlwm ntawm cov cuab yeej tshawb nrhiav roj av muaj peb yam tseem ceeb: qhov kub thiab txias, kev kub siab, thiab kev vibration muaj zog, uas ua rau cov qauv nruj rau kev ua cov pcb boards deb tshaj li cov khoom siv pej xeem. Los ntawm kev xav txog kev ua haujlwm, qhov tseem ceeb tshaj plaws yog qhov kev hloov pauv ntawm siab - kub resistant substrates - tshwj xeeb substrates nrog kub kub kuj yuav tsum tau xaiv, uas muaj peev xwm tswj kev ruaj ntseg nyob rau hauv luv luv - lub sij hawm siab - kub ib puag ncig thiab muaj zoo heev rwb thaiv tsev kev ua tau zoo thiab tshuaj corrosion kuj. Nyob rau tib lub sijhawm, qhov chaw sab hauv ntawm lub cuab yeej yog compact, thiab lub rooj tsavxwm pcb yuav tsum tau ua kom tiav siab - ntom ntom Circuit Court layout nyob rau hauv ib tug txwv me me. Qhov no yuav tsum muaj kev tswj xyuas meej ntawm kab dav thiab qhov sib nrug thaum lub sijhawm ua haujlwm kom paub tseeb tias tsis muaj kev pheej hmoo xws li luv luv Circuit Court thiab to ntawm circuits hauv qhov kub thiab txias. Tsis tas li ntawd, kev tshawb nrhiav cov twj paj nruag feem ntau nrog cov kev txav mus los thiab kev co hauv av, thiab kev tiv thaiv kev tawm dag zog thiab kev sib koom ua ke kev ntseeg siab ntawm pcb boards kuj yuav tsum tau ntxiv dag zog los ntawm kev ua haujlwm tshwj xeeb kom tsis txhob muaj kev cuam tshuam los yog Circuit Court breakage los ntawm kev co.
2, Kev Tshawb Fawb Txog Kev Tshawb Fawb: Cov txheej txheem thev naus laus zis rau siab - kub resistant pcb boards
Hauv kev ua haujlwm ntawm high-kub pcb boards, peb tsom mus rau peb lub hom phiaj tseem ceeb ntawm "kev ruaj khov, kev ua tau zoo, thiab kev ntseeg tau", tsim kom muaj cov txheej txheem thev naus laus zis tag nrho, thiab kov yeej cov teeb meem kev ua haujlwm hauv siab - qhov kub thiab txias.
(1) Substrate pretreatment: tso lub hauv paus rau qhov kub thiab txias
Qhov ua ntej- kev kho kom zoo ntawm cov substrate ncaj qha cuam tshuam rau qhov kawg kub ua haujlwm ntawm lub rooj tsavxwm pcb. Rau cov substrates tshwj xeeb, peb siv plasma nto kho technology - los ntawm bombarding lub nto ntawm lub substrate nrog siab -plasma zog, impurities xws li roj stains thiab oxide txheej raug tshem tawm, thiab ib tug micro ntxhib qauv yog tsim nyob rau saum npoo, zoo heev txhim kho qhov adhesion ntawm substrate thiab muag daim npog qhov ncauj zoo, kub thiab txias. cycling ib puag ncig, thiab zam cov teeb meem xws li delamination thiab detachment.
(2) Circuit Court ntau lawm: precision tswj ntawm kub stability
Lub Circuit Court yog lub hauv paus ntawm pcb board teeb liab kis tau tus mob, thiab qhov tseeb thiab oxidation tsis kam ntawm lub Circuit Court yog ib qho tseem ceeb nyob rau hauv high kub ib puag ncig. Peb siv high-precision laser direct imaging thev naus laus zis los hloov cov txheej txheem cuam tshuam ib txwm muaj, uas tuaj yeem tsim cov kab dav dav thiab qhov sib txawv, ua tau raws li qhov siab - cov teeb liab xaim ceev ntawm cov cuab yeej tshawb nrhiav roj av. Nyob rau tib lub sijhawm, nyob rau hauv cov txheej txheem electroplating ntawm Circuit Court, "nickel kub" ob npaug - txheej txheej electroplating yog saws - txheej hauv qab npib tsib xee tuaj yeem txhim kho corrosion tsis kam thiab hnav tsis kam ntawm Circuit Court, thaum cov txheej kub saum toj kawg nkaus muaj kev ua tau zoo thiab oxidation tsis kam. Txawm hais tias nws ua haujlwm rau lub sijhawm ntev ntawm qhov kub thiab txias, nws tuaj yeem ua kom ruaj khov Circuit Court tsis kam thiab ua kom qhov tseeb thiab txuas ntxiv ntawm cov teeb liab kis tau tus mob.
(3) Solder mask spraying machine processing: ntxiv dag zog rau kev tiv thaiv kub
Lub npog ntsej muag lub ntsej muag yog "txheej txheej tiv thaiv" ntawm lub rooj tsavxwm pcb, uas yuav tsum tau tswj xyuas qhov rwb thaiv tsev thiab adhesion ntawm qhov kub thiab txias. Peb siv lub tshuab npog ntsej muag lub ntsej muag kom ntseeg tau tias cov tuab tuab ntawm lub ntsej muag lub ntsej muag thiab tsis muaj qhov tsis xws li npuas lossis pinholes los ntawm kev tswj xyuas tag nrho cov txheej txheem. Cov txheej txheem kho tau txais cov txheej txheem cua sov segmented kom tag nrho crosslinking thiab kho cov txheej txheem ntawm daim npog ntsej muag, uas tseem tuaj yeem ua kom muaj kev tiv thaiv zoo hauv qhov kub thiab txias.
3, Kev Tswj Xyuas Zoo: Xyuas kom meej tias tag nrho cov txheej txheem ua tau raws li tus qauv rau kev ua haujlwm kub kub
Kev ntseeg siab ntawm cov cuab yeej tshawb nrhiav roj av yog ncaj qha ntsig txog kev nyab xeeb thiab kev ua haujlwm ntawm kev tshawb nrhiav kev ua haujlwm. Yog li ntawd, peb tau tsim kom muaj tag nrho cov txheej txheem tswj kev ua tau zoo uas npog "cov khoom siv raw khoom" kom ntseeg tau tias txhua qhov siab -kub pcb board ua tau raws li cov qauv nruj.
Nyob rau hauv cov txheej txheem ntawm kev tswj cov khoom siv raw, tag nrho cov substrates, tooj liab foils, solder mask inks, thiab lwm yam yog los ntawm zoo -cov npe nrov hauv kev lag luam, thiab cov neeg muag khoom yuav tsum tau muab cov ntaub ntawv pov thawj kev ntsuas kub ua haujlwm. Ua ntej txhua batch ntawm raw cov ntaub ntawv khaws cia, sampling xeem yuav tsum tau ua los xyuas kom meej cov cim tseem ceeb xws li qhov kub thiab txias stability ntawm lub substrate thiab lub siab - kub tej yam kuj ntawm lub solder daim npog qhov ncauj number case.
Thaum lub sijhawm ua haujlwm, ntau qhov kev tshawb nrhiav hauv online tau teeb tsa: tom qab lub tshuab hluav taws xob tau tsim, AOI cov cuab yeej siv los txheeb xyuas cov teeb meem hauv Circuit Court, uas zoo dua tsis txhob muaj teeb meem xws li kev sib txawv ntawm Circuit Court thiab luv luv Circuit Court; Tom qab lub npog ntsej muag kho tau zoo, qhov ntsuas kub tsis kam thiab kev ntsuas rwb thaiv tsev yog ua los xyuas kom meej tias cov nyhuv tiv thaiv tau raws li tus qauv. Nyob rau theem khoom tiav, kev ntsuas kev ua tau zoo yog ua tiav, suav nrog kev ntsuas siab -kub cycling, siab - ntsuas kev laus, ntsuas kev vibration, thiab lwm yam. Tag nrho cov ntaub ntawv ntsuas tau sau tseg hauv tiag- lub sijhawm los tsim cov ntaub ntawv zoo traceable, kom ntseeg tau tias cov khoom tsis tsim nyog yuav tsis nkag mus rau hauv lub khw.
