Taw qhia
Hauv kev tsim khoom ntawm PCBA, cov txheej txheem kho saum npoo ncaj qha cuam tshuam qhov zoo ntawm cov khoom, kev ntseeg tau ntawm cov khoom, thiab kev ua raws li ib puag ncig. Raws li cov kev cai ib puag ncig txuas ntxiv kom nruj thiab xaus - kev lag luam xav tau kom muaj kev ntseeg siab tau nce ntxiv, cov kev txwv ntawm cov txheej txheem tshuaj tsuag tshuaj pleev ib ce tau dhau los ua pom tseeb. Electrolytic Nickel-Immersion Gold (ENIG), raws li kev paub tab, tau txais kev pom zoo nyob rau hauv ntau cov haujlwm PCBA. Peb yuav txheeb xyuas cov txiaj ntsig zoo ntawm kev hloov pauv ntawm tin plating mus rau electrochemical nickel-gold plating hauv PCBA kev tsim khoom los ntawm qhov kev xav ntawm cov txheej txheem cov yam ntxwv, ib puag ncig yam, thiab daim ntawv thov scenarios.
Qhov xwm txheej tam sim no ntawm Tin Plating hauv PCBA Manufacturing
1. Tsis txaus Nto Flatness
Vim muaj kev cuam tshuam ntawm cov riam cua thaum lub sij hawm tin plating txheej txheem, lub thickness tis ntawm lub ncoo nto yog tsis sib xws, uas yuav yooj yim cuam tshuam rau lubqhov chaw zoo -pitch Cheebtsam, ib qho teeb meem tshwj xeeb tshaj yog nyob rau hauv siab - ntom PCBA tsim.
2. Qhov tseem ceeb thermal shock cuam tshuam rau lub substrate
Cov txheej txheem tin plating yuav tsum muaj kev kub siab -kub, uas ua rau muaj kev ntxhov siab thermal ntawm cov boards multilayer thiab siab -TG cov ntaub ntawv, uas yuav ua rau board warping lossis micro- tawg.
3. Ua kom ib puag ncig siab
Kev lig kev cai tin plating suav nrog txhuas lossis lwm yam hlau hnyav; txawm tias muaj cov hlau lead-dawb tin plating, siab- cov pa roj cua kub thiab cov seem seem yuav tsum tau kho, muab qhov xav tau ntau dua rau kev tswj hwm ib puag ncig.
Cov yam ntxwv ntawm ENIG txheej txheem
1. Zoo heev nto Flatness
Cov txheej kub tsim los ntawm cov tshuaj deposition muaj cov tuab tuab, ua rau nws haum rau precision ntim xws li BGA thiab QFN, thiab zoo txhim kho cov khoom sib dhos.
2. Kev ruaj ntseg SolderingKev ua tau zoo
Cov txheej npib tsib xee ua raws li qhov sib txawv ntawm qhov sib txawv, thaum cov txheej kub muab cov dej ntub dej zoo heev, ua rau cov txheej txheem sib koom ua ke ruaj khov thiab txo qhov kev pheej hmoo ntawm cov pob qij txha txias thiab txias soldering.
3. Corrosion Resistance thiab Long -Term Reliability
Cov txheej txheem ENIG muaj zog tiv thaiv oxidation, tswj kev ruaj ntseg thaum lub sij hawm ntev - khaws cia lossis nyob rau hauv ib puag ncig nyuaj. Nws yog qhov tsim nyog rau siab - kev ntseeg siab PCBs siv hauv kev tswj hwm kev lag luam thiab khoom siv kho mob.
Cov Txheej Txheem Hloov Cov Txheej Txheem Ua los ntawm Kev Tiv Thaiv Ib puag ncig
1. Ob lub siab los ntawm cov kev cai thiab kev ua lag luam
Cov kev cai xws li RoHS thiab REACH txuas ntxiv mus, ua kom muaj kev txwv nruj dua rau cov khoom phom sij. Hauv kev tshuaj xyuas cov saw hlau, qhov kawg - cov neeg siv khoom lag luam tau teeb tsa cov qauv siab dua rau kev ua haujlwm ib puag ncig ntawm PCB cov tuam txhab.
2. Cov nqi pov tseg nce ntxiv
Cov nqi cuam tshuam nrog kev kho cov khib nyiab tin dross thiab tso pa tawm thaum lub sij hawm tin plating txheej txheem tau nce xyoo los ntawm lub xyoo, whereas tshuaj npib tsib xee - kub plating, nyob rau hauv kaw- lub voj ntau lawm, yog yooj yim los tswj tsis tu ncua.
3. Kev thov tau tsav los ntawm High-Cov khoom kawg
Cov haujlwm xws li 5G kev sib txuas lus, khoom siv hluav taws xob hauv tsheb, thiab cov servers tau ua ib txwm muaj - xav tau ntau dua ntawm qhov tseeb thiab kev ntseeg siab ntawm PCBs, tsav tsheb tuam txhab lag luam kom tau txais cov txheej txheem kho saum npoo zoo dua.
Cov kev sib tw hauv kev hloov pauv ntawm Solder Spraying rau ENIG
1. Kev hloov ntawm tus nqi tsim
Cov khoom siv thiab cov txheej txheem cov nqi ntawm ENIG yog siab dua li cov tshuaj tsuag tshuaj tsuag, yuav tsum muaj qhov sib npaug raws li cov khoom muag thiab kev xav tau ntawm kev lag luam.
2. Cov txheej txheem siab dua yuav tsum tau tswj
ENIG tsim cov kev cai nruj rau kev tswj cov tshuaj muaj pes tsawg leeg, qhov kub thiab txias, thiab lub sijhawm tso tawm. Kev tswj tsis tau zoo yuav ua rau muaj teeb meem zoo xws li "dub boards."
3. Kev tsim thiab txheej txheem kev hloov kho
Thaum hloov los ntawm tin plating rau ENIG, qee qhov kev tsim PCBA yuav tsum tau rov ntsuam xyuas dua ntawm qhov ntev ntawm lub ncoo, kev ua siab ntev, thiab cov khoom siv soldering los xyuas kom meej tag nrho kev sib raug zoo.
Teb cov tswv yim rau PCBA Manufacturers
1. Tsim kom muaj ntau- Txheej Txheem Txheej Txheem
Flexibly muab ntau yam kev daws teeb meem saum npoo av-xws li tin plating, immersion kub, thiab OSP-raws li cov neeg siv khoom hom los txhim kho kev lag luam adaptability.
2. Txhim kho cov txheej txheem tswj thiab tshuaj xyuas muaj peev xwm
Siv kev soj ntsuam online thiab kev sim kuaj hauv online kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov txheej txheem ENIG thiab txo qis batch - rau - batch variations.
3. Kev koom nrog Cov Neeg Siv Khoom Pem Hauv Ntej -Xaum Tsim Phaj
Tau koom nrog hauv theem DFM los koom tes nrog cov neeg siv khoom ntawm kev txhim kho PCBA tsim, ua kom lawv zoo dua rau cov txheej txheem phiaj xwm thiab txo cov kev pheej hmoo hauv cov theem tom ntej.
Xaus
Kev hloov ntawm tin plating mus rau electroless npib tsib xee-kub tsis yog ib qho kev hloov kho tshiab xwb. Nws yog ib qho kev xaiv uas tsis muaj kev xaiv rau PCBA cov tuam txhab los daws cov teeb meem ib puag ncig thiab ua tau raws li qhov xav tau ntawm kev lag luam siab - kawg. Raws li cov txheej txheem yuav tsum tau sib txawv ntawm cov txheej txheem sib txawv, xaiv qhov kev kho kom haum rau saum npoo yuav tsum muaj kev ntsuam xyuas dav uas sib npaug tus nqi, kev ua tau zoo, thiab kev ntseeg tau.
