Qhov sib txawv tseem ceeb ntawm HDI thiab PCB ib txwm muaj - lub sijhawm tshiab ntawm kev sib txuas ceev ceev
HDI (High Density Interconnection) yog lub rooj tsavxwm me me uas tsim los rau cov neeg siv khoom tsawg. Piv nrog rau cov PCBs ib txwm, qhov tseem ceeb tshaj plaws ntawm HDI yog nws cov xov hluav taws xob siab. Qhov sib txawv ntawm ob qho no feem ntau pom tseeb hauv plaub yam hauv qab no.
1. HDI me dua thiab sib dua hauv qhov hnyav
HDI boards yog ua los ntawm cov boards ob sab ib txwm ua cov core boards thiab raug laminated los ntawm kev lamination tas mus li. Hom circuit board no ua los ntawm kev lamination tas mus li kuj hu ua Build-up Multilayer board (BUM). Piv nrog cov circuit boards ib txwm, HDIs muaj qhov zoo ntawm "lub teeb, nyias, luv, thiab me".
Qhov kev sib txuas hluav taws xob ntawm HDI board txheej yog ua tiav los ntawm kev sib txuas conductive through-hole, faus/dig muag via. Nws cov qauv txawv ntawm cov circuit boards ntau txheej. Muaj ntau lub micro-fub/dig muag vias siv hauv HDI boards. HDI siv laser direct drilling, thaum tus qauv PCB feem ntau siv mechanical drilling, yog li tus lej ntawm cov txheej thiab qhov sib piv feem ntau raug txo qis.
2. Cov txheej txheem tsim khoom ntawm HDI motherboard
Qhov ceev ntawm HDI boards feem ntau yog pom tseeb hauv qhov ceev ntawm cov qhov, kab, ncoo, thiab interlayer thickness.
Qhov me me ntawm qhov: Lub rooj tsavxwm HDI muaj cov qauv tsim qhov me me xws li qhov dig muag, uas feem ntau pom tseeb hauv cov thev naus laus zis tsim qhov me me nrog lub cheeb tsawg dua 150um thiab cov kev xav tau siab hauv cov nqi, kev ua haujlwm zoo thiab kev tswj qhov tseeb ntawm qhov. Tsuas muaj qhov me me ntawm cov rooj tsavxwm ntau txheej thiab tsis muaj qhov me me faus / dig muag.
Kev txhim kho qhov dav/qhov sib nrug ntawm kab: Qhov no feem ntau yog pom tseeb hauv cov kev cai nruj dua rau cov kab tsis zoo thiab qhov roughness ntawm kab. Feem ntau, qhov dav/qhov sib nrug ntawm kab yuav tsum tsis pub tshaj 76.2um.
Qhov ceev ntawm cov ntaub qhwv: qhov ceev ntawm kev sib txuas lus yog ntau dua 50 / cm2
Kev nyias nyias ntawm dielectric thickness: Qhov no feem ntau yog pom tseeb hauv qhov sib txawv ntawm cov txheej txheem dielectric thickness mus rau 80um thiab hauv qab, thiab cov kev cai rau kev sib npaug ntawm cov tuab tau dhau los ua ntau dua thiab ntau dua, tshwj xeeb tshaj yog rau cov laug cam siab thiab cov khoom ntim khoom nrog cov yam ntxwv impedance tswj.
3. Kev ua haujlwm hluav taws xob ntawm HDI board zoo dua
HDI tsis yog tsuas yog ua rau cov qauv tsim khoom kawg kom me dua xwb, tab sis kuj ua tau raws li cov qauv siab dua rau kev ua haujlwm hluav taws xob thiab kev ua haujlwm zoo.
Qhov kev sib txuas ntawm HDI ua rau muaj zog dua thiab txhim kho kev ntseeg tau. Tsis tas li ntawd, HDI boards muaj kev txhim kho zoo dua hauv RF cuam tshuam, electromagnetic wave cuam tshuam, electrostatic discharge, heat conduction, thiab lwm yam. HDI kuj siv cov thev naus laus zis digital signal process control (DSP) tag nrho thiab ntau yam thev naus laus zis patented, nrog rau kev hloov pauv tag nrho thiab muaj peev xwm thauj khoom luv luv.
4. Cov laug cam HDI muaj cov kev cai siab heev rau kev txuas cov khoom faus rau hauv av.
Txawm hais tias nws yog qhov loj ntawm lub rooj tsavxwm lossis kev ua haujlwm hluav taws xob, HDI zoo dua li PCB ib txwm muaj. Txhua lub npib muaj ob sab. Sab tod ntawm HDI yog tias vim nws tau tsim ua PCB siab, nws qhov kev tsim khoom thiab qhov nyuaj ntawm cov txheej txheem siab dua li ntawm PCB ib txwm muaj. Kuj tseem muaj ntau yam teeb meem uas yuav tsum tau them sai sai thaum lub sijhawm tsim khoom - tshwj xeeb tshaj yog faus los ntawm kev ntsaws.
Tam sim no, qhov mob tseem ceeb thiab qhov nyuaj hauv kev tsim HDI yog faus los ntawm kev ntsaws. Yog tias HDI faus los ntawm kev tsis ntsaws kom raug, yuav muaj teeb meem loj heev, suav nrog cov npoo ntawm lub rooj tsavxwm tsis sib npaug, cov tuab dielectric tsis sib npaug, thiab cov ntaub qhwv tsis muaj qhov, thiab lwm yam.
Qhov saum npoo ntawm lub rooj tsavxwm tsis sib npaug thiab cov kab tsis ncaj, ua rau muaj qhov tshwm sim ntawm ntug hiav txwv hauv qhov kev nyuaj siab, uas yuav ua rau muaj qhov tsis zoo xws li qhov sib txawv ntawm kab thiab kev sib txuas.
Tus yam ntxwv impedance kuj tseem yuav hloov pauv vim yog qhov tuab dielectric tsis sib xws, ua rau lub teeb liab tsis ruaj khov.
Qhov tsis sib xws ntawm lub soldering pad yuav ua rau tsis zoo ntawm cov ntim khoom tom qab thiab kev poob ntawm cov khoom.
Yog li ntawd, tsis yog txhua tus neeg tsim khoom PCB muaj peev xwm thiab lub zog los ua haujlwm zoo ntawm HDI.
