Raws li alumina ceramic substrates dhau los ua nyias thiab cov khoom siv hluav taws xob txuas ntxiv zuj zus, cov tuam txhab lag luam tau xav tau ntau dua ntawm laser-drilled micro qhov. Hauv cov ntawv thov xws li ntim khoom semiconductor, ceramic PCBs, fais fab modules, RF cov khoom siv, thiab cov khoom siv kho mob, lub qhov zoo cuam tshuam ncaj qha rau metallization, kev sib dhos kev ntseeg siab, thiab ntev -cov khoom lag luam.
Ntawm ntau yam kev siv laser drilling, kauv trepanning yog dav lees paub tias yog cov txheej txheem nyiam ua kom tau txais qhov siab -zoo micro qhov. Txawm hais tias nws feem ntau qeeb dua li laser percussion drilling, nws qhov zoo tshaj qhov raug thiab cov txheej txheem ruaj ntseg feem ntau ua rau nws xaiv zoo dua rau kev tsim khoom.
Kab lus no piav qhia vim li cas kauv trepanning tsis tu ncua ua kom zoo dua micro qhov zoo hauv alumina ceramics thiab thaum nws yuav tsum tau xaiv dua li txoj kev drilling sai.
Vim Li Cas Qhov Qhov Zoo Li Cas?
Micro qhov zoo yog deb tshaj qhov pom. Txawm tias me me tsis xws luag tuaj yeem cuam tshuam rau cov txheej txheem kev tsim khoom thiab kev ntseeg tau ntawm cov khoom.
Tsis zoo- qhov zoo yuav ua rau:
Ntug chipping
Micro{0}} tawg
Tshaj qhov taper
Rough sidewalls
Tsis zoo metallization adhesion
Txo cov neeg kho tshuab lub zog
Txo cov qoob loo ntau lawm
Rau kev lag luam nrog cov qauv zoo nruj, kev txhim kho qhov zoo feem ntau muaj txiaj ntsig ntau dua li tsuas yog nce qhov nrawm nrawm.
Yuav Ua Li Cas Kauv Trepanning Ua Haujlwm
Tsis zoo li percussion drilling, uas concentrates ntau lub laser pulses ntawm ib qho chaw ruaj khov kom txog thaum cov khoom nkag mus, muab kauv trepanning tshem tawm cov khoom maj mam raws li txoj hauv kev uas tau muab kauv.
Lub laser beam pib nyob ze ntawm qhov nruab nrab ntawm lub qhov thiab nce mus rau sab nraud thaum tshem cov txheej nyias nyias. Es tsis txhob ua kom muaj cua sov ntau hauv ib qho chaw, lub zog raug faib ntau tus sib npaug thoob plaws hauv cov txheej txheem machining.
Qhov kev tswj cov khoom tshem tawm no yog qhov tseem ceeb vim li cas kauv trepanning muab lub qhov zoo tshaj plaws.
Qis Thermal Stress
Ib qho ntawm cov teeb meem loj tshaj plaws thaum laser drilling alumina ceramics yog thermal stress.
Alumina yog cov khoom tawv thiab nkig. Thaum tshav kub kub ntau dhau nyob rau hauv ib qho chaw me me, thermal expansion thiab contraction tuaj yeem tsim kev ntxhov siab sab hauv uas ua rau cov kab nrib pleb lossis ntug kev puas tsuaj.
Vim hais tias kauv trepanning tshem tawm cov khoom txheej los ntawm txheej, cov cua kub tsub zuj zuj yog txo qis. Qhov qis thermal load minimizes kev ntxhov siab nyob ib ncig ntawm lub qhov thiab txhim kho machining stability.
Yog li ntawd, kauv trepanning yog tshwj xeeb tshaj yog haum rau daim ntaub ntawv uas yuav tsum tau high structural kev ncaj ncees.
Txo Edge Chiping
Ntug chipping yog ib qho teeb meem zoo tshaj plaws hauv ceramic laser drilling.
Thaum lub sij hawm siab -zog percussion drilling, molten cov ntaub ntawv thiab thermal shock tuaj yeem yooj yim tawg ceramic nplej ze ntawm lub qhov nkag, ua cov chips tsis tu ncua nyob ib ncig ntawm ntug.
Kauv trepanning txo qhov kev pheej hmoo no los ntawm kev faib hluav taws xob laser hla txoj kev txiav loj dua li tsis yog tsom rau ntawm ib qho chaw.
Cov txiaj ntsig zoo xws li:
Cov ntug me me tsis xws luag
Lub qhov nkag huv huv
Txhim kho qhov sib xws
Cov tsos zoo dua tom qab metallization
Rau ceramic substrates siv nyob rau hauv cov khoom siv hluav taws xob, txo qis ntug chipping yog qhov tseem ceeb rau kev tswj cov txheej txheem kev ntseeg siab.
Lower Qhov Taper
Qhov taper yog hais txog qhov sib txawv ntawm qhov nkag thiab tawm txoj kab uas hla ntawm ib lub qhov.
Lub kaum sab xis loj tuaj yeem tsim teeb meem thaum:
Los ntawm metallization
Pin insertion
Kev siv dej ntws
Precision sib dhos
Vim tias kauv trepanning maj mam nthuav lub qhov thaum tso cai rau kev tswj hwm ntawm txoj kev laser, nws feem ntau ua rau cov phab ntsa zoo sib xws thiab qis dua dua li percussion drilling.
Rau cov ntawv thov uas xav tau ze li ntawm qhov cylindrical, kauv trepanning feem ntau yog qhov kev daws teeb meem.
Zoo dua qhov Roundness
Lub qhov roundness dhau los ua qhov tseem ceeb dua li qhov txoj kab uas hla ntawm lub qhov txo qis.
Tsis zoo roundness tuaj yeem cuam tshuam:
Kev ua haujlwm hluav taws xob
Mechanical alignment
Connector sib dhos
Sensor raug
Txij li thaum muab kauv trepanning ua raws li kev tswj lub voj voog ncig, qhov kawg qhov geometry feem ntau zoo ib yam li qhov uas tsim los ntawm qhov chaw nres tsheb drilling.
Qhov no ua rau cov txheej txheem tshwj xeeb yog tsim rau precision micro qhov hauv qab 100 μm.
Ntshiab Sidewalls
Qhov sidewall zoo cuam tshuam rau ob qho tib si lub zog thiab cov txheej txheem tsim khoom tom ntej.
Rough sidewalls tuaj yeem ntes cov khib nyiab, txo cov txheej adhesion, lossis ua kom muaj kev ntxhov siab ntau ntxiv.
Vim tias kauv trepanning tshem tawm cov khoom maj mam siv ntau qhov kev tswj xyuas, nws feem ntau ua rau:
Smoother sidewalls
Tsawg dua cov khoom siv
Txo cov cua sov- thaj chaw cuam tshuam
Kev tshaj tawm yooj yim dua - ua thiab tu
Cov txiaj ntsig no muaj txiaj ntsig tshwj xeeb hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob siab - kev ntseeg tau.
Txhim kho txheej txheem ruaj khov
Kev tsim khoom loj yuav tsum tau ntau tshaj qhov tsim tau ib lub qhov zoo.
Cov neeg tsim khoom xav tau txhua lub qhov hla ntau txhiab tus workpieces kom tau raws li tus qauv zoo.
Kev tswj cov khoom tshem tawm cov txheej txheem ntawm kauv trepanning pab txo cov txheej txheem kev hloov pauv los ntawm:
Cov khoom thickness hloov
Me me laser zog fluctuations
Thermal tsub zuj zuj
Beam positioning yuam kev
Yog li ntawd, kauv trepanning feem ntau xa zoo sib xws thaum lub sij hawm tas mus li ntau lawm.
Thaum twg Koj Yuav Tsum XaivKauv Trepanning?
Txawm hais tias percussion drilling tseem yog txoj kev drilling ceev tshaj plaws, kauv trepanning feem ntau pom zoo thaum qhov zoo yog qhov kev txhawj xeeb tseem ceeb.
Cov ntawv thov ib txwm muaj xws li:
Semiconductor ceramic substrate
Lub zog hluav taws xob modules
Ceramic PCBs
RF thiab microwave Cheebtsam
Cov khoom siv kho mob ceramic
Automotive electronics
High -ntaus sib txuas substrates
Nws tseem yog qhov kev xaiv zoo tshaj plaws thaum:
Qhov txoj kab uas hla yog qis dua 100 μm
Tsawg taper yog yuav tsum tau
Ntug chipping yuav tsum tau txo qis
Thick alumina substrates yog ua tiav
Ntev - cov khoom lag luam kev ntseeg siab yog qhov tseem ceeb
Ceev vs. Zoo: Nrhiav qhov zoo sib npaug
Xaiv cov txheej txheem laser drilling yuav tsum tsis txhob ua raws li qhov nrawm nrawm.
Thaum percussion drilling tuaj yeem tsim ntau qhov ib ob, qhov tsis zoo ntawm lub qhov yuav ua rau lub sijhawm tshuaj xyuas, rov ua dua, thiab cov khoom seem.
Kauv trepanning feem ntau xav tau lub voj voog ua haujlwm ntev dua, tab sis nws qhov sib xws ntau dua thiab qis dua tus nqi feem ntau ua rau muaj txiaj ntsig ntau dua.
Rau cov tuam txhab tsim khoom ntawm cov khoom siv hluav taws xob muaj txiaj ntsig siab, tag nrho cov txiaj ntsig ntawm cov khoom lag luam feem ntau yog qhov qhia tau tias muaj txiaj ntsig zoo dua li qhov drilling ceev ib leeg.
Xaus
Kauv trepanning tau dhau los ua txoj kev nyiam laser drilling rau siab - zoo alumina ceramic micro qhov vim nws tshem tawm cov khoom maj mam, txo cov thermal stress, thiab muab kev tswj ntau dua ntawm qhov geometry.
Piv nrog percussion drilling, nws muaj qhov zoo ntawm ntug zoo, taper tswj, roundness, sidewall tiav, thiab ntau lawm sib xws. Txawm hais tias cov txheej txheem qeeb qeeb, nws qhov zoo tshaj qhov zoo feem ntau ua rau muaj kev tsim khoom ntau dua thiab ntev dua - cov khoom lag luam ntseeg tau.
Thaum xaiv cov txheej txheem laser drilling, cov tuam txhab lag luam yuav tsum xav txog tsis yog tsuas yog kev ua haujlwm ceev xwb tab sis kuj yog qhov yuav tsum tau ua ntawm daim ntawv thov zaum kawg. Rau kev xav tau hluav taws xob, semiconductor, thiab cov khoom siv kho mob ceramic, kauv trepanning tseem yog ib qho kev daws teeb meem zoo tshaj plaws.
