Nyob rau hauv niaj hnub high-tech era, kev loj hlob sai ntawm cov khoom siv hluav taws xob tau ua rau muaj kev loj hlob tseem ceeb hauv PCB (Printed Circuit Board) thev naus laus zis. Ordinary PCB thiabHDI(High Density Interconnect) yog ob qho tib si siv PCB thev naus laus zis, uas muaj qhov sib txawv tseem ceeb hauv kev tsim, tsim khoom, thiab kev siv.
Ua ntej, qhov sib txawv tseem ceeb ntawm PCB thiab HDI li niaj zaus nyob hauv kab ceev. Ib qho PCB tsis tu ncua yog ib hom kev siv hluav taws xob hauv Circuit Court uas tsis tshua muaj hluav taws xob, tsim rau qee yam khoom siv hluav taws xob yooj yim. Nrog kev pab los ntawm kev tsim cov thev naus laus zis tshiab, HDIPCB tau ua tiav cov kab ntau dua. HDIPCB siv qhov me me aperture thiab kab dav kom ua tiav ntau qhov kev sib txuas hauv Circuit Court hauv qhov chaw tsawg. Cov HDI PCBs me me tuaj yeem muab cov teeb liab sib kis tau zoo dua thiab ua haujlwm zoo dua electromagnetic, ua rau lawv haum rau cov khoom siv hluav taws xob ntau zaus thiab ceev ceev.
Qhov thib ob, muaj qhov sib txawv ntawm cov khoom siv ceev thiab muaj qhov chaw nruab nrab ntawm PCBs thiab HDIs. Ordinary PCBs feem ntau siv cov khoom ntim hauv cov khoom ntim, nrog cov khoom siv tsawg tsawg. HDIPCB siv cov khoom ntim micro xws li BGA (BallGridArray) thiab CSP (ChipScalePackage), uas yog qhov me me thiab muaj ntau tus pins, tso cai rau kev sib txuas ntxiv hauv qhov chaw txwv. Qhov no tseem ua rau HDI PCBs ua lub luag haujlwm ntau dua hauv cov khoom siv hluav taws xob me me, xws li smartphones, ntsiav tshuaj, thiab lwm yam.
Tsis tas li ntawd, cov PCBs zoo tib yam thiab HDIPCBs kuj txawv ntawm cov yam ntxwv hluav taws xob. HDI PCB txais cov xov hlau luv luv, qhov sib nrug me me thiab qhov aperture, txo cov teeb liab kis tau tus mob ncua sij hawm thiab teeb liab poob, muab cov teeb liab zoo dua. Hauv cov khoom siv hluav taws xob ntau zaus thiab ceev ceev, HDIPCB tuaj yeem muab cov teeb liab ruaj khov dua kev ua haujlwm, txo kev cuam tshuam thiab suab nrov, thiab txhim kho kev ntseeg tau thiab kev ua haujlwm.
