Lus Qhia Ua Ntej: Los Ntawm Kev Sib Txuas Mus Rau Cov Kev Sib Tw Qib Micron
Nrog kev nce qib sai ntawm kev sib txuas lus 5G, AI servers, thiabcov thev naus laus zis ntim khoom siab heev,Kev tsim khoom PCB (Printed Circuit Board) tau hloov zuj zus mus rau hauv lub platform uas muaj qhov ceev ceev, microvia-driven. Kev siv HDI boards, multilayer PCBs, thiab IC Substrates qhia txog kev hloov mus rau lub sijhawm tsim khoom micron-scale, qhov twg via drilling ua lub luag haujlwm tseem ceeb hauv kev tsim cov kev sib txuas hluav taws xob interlayer txhim khu kev qha (Via Interconnects). Txawm li cas los xij, raws li qhov drilling diameters shrink hauv qab 0.2 hli thiab txawm tias 0.1 hli, cov txheej txheem machining ib txwm tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov ntaub ntawv siab zaus thiab ultra-precision ntau lawm, ua rau cov cuab yeej hnav, micro drill tawg, thiab tsis ruaj khov qhov zoo ntawm phab ntsa qhov teeb meem tseem ceeb cuam tshuam rau PCB cov txiaj ntsig thiab kev tsim khoom sib xws.
Kev Ua Haujlwm Sib Tw hauv Microvia Drilling
Hauv kev tsim PCB uas muaj cov khoom siv ntau, kev khawb me me yog ib qho txheej txheem uas rhiab heev uas tswj hwm los ntawm cov cuab yeej siv, cov khoom siv, thiab kev txiav. Ntawm qhov ceev ntawm lub spindle siab heev, feem ntau ncav cuag kaum txhiab txog pua pua txhiab RPM, qhov ntug txiav tsawg heev ntawm cov tshuab khawb me me ua rau lawv yooj yim rau cov teebmeem thermal, uas ua rau cov cuab yeej hnav sai dua, ua rau cov coefficient ntawm kev sib txhuam nce ntxiv, thiab ua rau cov xwm txheej txiav tsis ruaj khov. Thaum cov ntug txiav poob qis, kev tshem tawm cov khoom siv hloov pauv mus rau hauv kev hloov pauv thiab kev rhuav tshem, ua rau phab ntsa qhov roughness, burr tsim, thiab resin adhesion, tag nrho cov no sib sau ua ke thoob plaws cov microvia arrays thiab txo qis kev ruaj khov ntawm cov txheej txheem.
Qhov teeb meem no yuav tshwm sim ntau dua thaum siv cov khoom siv siab heev xws li PTFE, BT resin, thiab ABF, qhov twg cov modulus qis thiab cov yam ntxwv adhesion siab txhawb nqa resin smear (Smear) thiab wicking effects (Wicking) raws cov phab ntsa via. Cov qhov tsis zoo no ua rau cov qauv geometry tsis zoo, ua rau qhov tseeb ntawm qhov ntev tsis zoo, thiab cuam tshuam tsis zoo rau cov txheej txheem downstream suav nrog kev ntseeg siab ntawm metallization thiab electroplating, ua rau muaj kev pheej hmoo loj rau cov ntawv thov siab xws li IC Substrates, qhov twg qhov tsis zoo tsis kam yog qis heev.
Kev Xaiv Tshuab Tsim Kho Nto thiab Kev Siv Tshuab Txheej
Yuav kom txhim kho kev ua haujlwm ntawm lub tshuab me me, kev tsim kho qhov chaw los ntawm cov thev naus laus zis siab heev yog qhov tseem ceeb. Txawm hais tias electroless plating thiab CVD (Chemical Vapor Deposition) tuaj yeem ua rau qhov nyuaj ntawm qhov chaw nce ntxiv rau qee qhov, lawv muaj kev txwv hauv kev siv me me, suav nrog kev sib npaug ntawm cov txheej txheem tsis zoo, qhov kub siab, kev puas tsuaj rau cov khoom siv, thiab kev ntxhov siab ntau dhau ua rau cov txheej txheem tawg hauv qab cov xwm txheej ua haujlwm ceev.
Qhov sib txawv, PVD (Physical Vapor Deposition) Vacuum Coating Technology muab kev daws teeb meem zoo dua rau kev siv micro drilling, vim nws ua rau muaj kev tso cov zaj duab xis nyias nyias, sib xws hauv qhov kub qis nrog kev nplaum zoo heev, txo cov coefficient sib txhuam, thiab txhim kho kev hnav tsis kam, ua kom cov txheej txheem txiav ruaj khov thaum txo cov resin smear thiab txhim kho kev ua haujlwm ntawm phab ntsa qhov.
Zhenhua Lub Tshuab Nqus Tsev Micro Drill Txheej Tshuaj
Lub MFA0605 PVD Coating System yog tsim tshwj xeeb rau kev siv cov cuab yeej ua haujlwm siab hauv kev lag luam PCB. Nruab nrog lub tshuab lim dej arc ion plating uas nws tus kheej tsim, nws tshem tawm cov khoom loj heev uas tsim thaum lub sijhawm tso tawm, ua kom cov zaj duab xis zoo dua thiab kev sib xws ntawm cov txheej. Lub kaw lus txhawb nqa cov txheej txheem Ta-C (tetrahedral amorphous carbon) siab heev, xa cov tawv tawv siab heev txog li 63 GPa, nrog rau cov coefficient sib txhuam qis, kev tiv thaiv corrosion zoo heev, thiab lub cuab yeej siv tau ntev dua. Tib lub sijhawm, nws muaj peev xwm tso ntau yam txheej txheej ua haujlwm siab xws li AlTiN, AlCrN, TiCrAlN, TiAlSiN, thiab CrN, ua rau nws hloov tau yooj yim rau PCB micro drills, cov cuab yeej txiav, cov pwm precision, thiab cov khoom siv tsheb, thaum tswj kev nplaum ruaj khov, kev sib xws zoo heev, thiab kev ua haujlwm zoo ntawm cov zaj duab xis nyias nyias hauv cov chaw tsim khoom loj.
Xaus lus
Thaum kev tsim khoom PCB txuas ntxiv mus rau qhov ceev dua, qhov me dua, thiab cov qauv nyuaj dua, lub peev xwm khawb me me tau dhau los ua qhov tseem ceeb hauv kev tsim khoom zoo thiab kev sib tw. Hauv cov ntsiab lus no, kev txheej txheem cuab yeej tsis yog kev txhim kho ntxiv lawm tab sis yog cov thev naus laus zis tseem ceeb uas txiav txim siab ncaj qha rau lub neej ntawm cov cuab yeej, qhov zoo ntawm qhov, thiab kev ruaj khov ntawm cov txheej txheem. Siv PVD Vacuum Coating Technology, Zhenhua Vacuum txuas ntxiv txhim kho kev sib xws ntawm cov txheej txheem, kev ruaj khov ntawm zaj duab xis, thiab kev sib xws ntawm cov khoom, ua rau muaj kev ua tau zoo hauv cov ntaub ntawv siab thiab kev khawb microvia zoo heev.
