Lub hauv paus rau phau ntawv
HDI yog ib qho lus luv rau high-density interconnect. Nws yog cov txheej txheem tsim qauv pcb nyuaj. HDI PCB thev naus laus zis tuaj yeem txiav cov kab laug cam hauv PCB teb. Cov thev naus laus zis tseem muab kev ua tau zoo siab thiab ntau dua cov xov hlau thiab circuits.
Los ntawm txoj kev, HDI Circuit Court board yog tsim txawv dua li qub luam ntawv circuit Court boards.
HDI lub hau pbse yog powered los ntawm vias me me, cov kab thiab chaw. Hdi Compbs yog lub teeb heev, uas yog ze rau lawv miniaturization.
Ntawm qhov tod tes, HDI yog tus cwj pwm los ntawm kev sib kis tau mob siab, tswj hluav taws xob hluav taws xob ntau, thiab tswj hwm ntawm PCB. Vim tias lub miniaturization ntawm pawg thawj coj, ceev ceev yog siab.
Microvias, dig muag thiab faus vias thiab kev ua tau zoo, cov ntaub ntawv nyias nyias, cov ntaub ntawv nyias nyias thiab cov ntsiav tshuaj zoo yog txhua txoj kab ntawm HDI luam tawm cov laug cam.
Engineers yuav tsum muaj kev nkag siab zoo ntawm tus qauv tsim qauv thiab HDI pcb tsim kev lag luam. Microchamips ntawm HDI luam tawm cov bacuital boards yuav tsum muaj kev saib xyuas tshwj xeeb thoob plaws hauv cov txheej txheem los, nrog rau kev sib dhos zoo.
Hauv kev cog lus tsim qauv zoo li Laptops, lub xov tooj txawb, HDI PCBs me me thiab qhov hnyav. Vim yog lawv qhov loj me me, HDI PCBs tseem muaj tsawg dua rau cov kab nrib pleb.
HDI vias
Vias yog qhov nyob hauv tus PCB uas tau siv los txuas cov sib txuas sib txuas sib txawv hauv PCB. Siv ntau txheej thiab txuas lawv nrog Vias txo cov PCB loj. Txij li thaum lub hom phiaj tseem ceeb ntawm lub rooj tsavxwm HDI yog txhawm rau txo nws qhov loj, Vias yog ib qho tseem ceeb tshaj plaws. Muaj ntau hom sib txawv ntawm cov qhov.
THROAD LUB QHOV KEV NTAWM
Nws mus dhau tag nrho PCB, los ntawm txheej saum npoo mus rau hauv qab txheej, thiab yog hu ua ib qho ntawm. Txij ntawm no, lawv txuas txhua txheej ntawm cov ntawv luam tawm Circuit Coad. Txawm li cas los xij, kev tawm ntawm kev coj mus ntau qhov chaw thiab txo chaw seem.
Dig muagntawm
Qhov muag tsis pom kev yooj yim txuas cov txheej txheej sab nraud mus rau txheej sab hauv ntawm PCB. Tsis tas yuav tho tag nrho pcb.
Faus ntawm
Forned Vias yog siv los txuas cov khaubncaws sab phaj ntawm PCB. Furied Vias tsis pom los ntawm sab nraud ntawm PCB.
Microntawm
Micro Vias yog qhov me tshaj plaws ntawm qhov loj me tsawg dua 6 MILS. Koj yuav tsum tau siv laser drilling los tsim micro vias. Yog li yeej, microvias yog siv rau HDI cov laug cam. Qhov no yog vim nws loj. Txij li thaum koj xav tau cov kev sib xyaw ua ke thiab tsis tuaj yeem nkim chaw hauv HDI pcb, nws yog cov paub qab hau los hloov lwm yam vias nrog microvias. Tsis tas li ntawd, microvias tsis txom nyem los ntawm cov teeb meem nthuav kub (CTE) vim tias lawv cov luv luv.
Daim duab
HDI pcb stack yog txheej txheej txheej-los ntawm txheej txheej. Tus naj npawb ntawm cov khaubncaws sab nraud povtseg lossis cov sib tsoo tuaj yeem txiav txim siab raws li yuav tsum tau ua. Txawm li cas los xij, qhov no tuaj yeem yog 8 txheej rau 40 txheej lossis ntau dua.
Tab sis tus naj npawb ntawm txheej ntawm txheej nyob ntawm qhov ntom ntawm cov kab. Multilayer stacking tuaj yeem pab koj txo cov pcb loj. Nws kuj tseem txo cov nqi tsim khoom.
Los ntawm txoj kev, los txiav txim siab tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm ib HDI pcb, koj yuav tsum txiav txim siab qhov loj me thiab cov nets ntawm txhua txheej. Tom qab paub lawv, koj tuaj yeem xam cov txheej txheej uas yuav tsum muaj rau koj HDI Board.
Cov lus qhia los tsim HDI PCB
1. Xaiv cov khoom tivthaiv. HDI boards xav tau cov lej siab siab thiab BGA me dua 0.65 hli. Koj yuav tsum tau xaiv lawv ntse raws li lawv cuam tshuam los ntawm hom, lw dav thiab HDI pcb stack-up.
2. Koj yuav tsum tau siv Microvias ntawm HDI Board. Qhov no yuav tso cai rau koj kom tau txais ob npaug ntawm qhov chaw ntawm ib qho ntawm lossis lwm yam.
3. Cov ntaub ntawv uas muaj ob qho tib si zoo thiab txuag tau yuav tsum tau siv. Nws yog qhov tseem ceeb rau kev tsim khoom lag luam ntawm cov khoom.
4. Kom tau txais lub tiaj tus pcb nto, koj yuav tsum sau qhov ntawm qhov.
5. Sim xaiv cov ntaub ntawv nrog tib tus nqi CTE rau txhua txheej.
6. Ua tib zoo mloog rau kev tswj hwm cua sov. Nco ntsoov tias koj tsim qauv zoo thiab teeb tsa cov khaubncaws sab nraud povtseg uas tuaj yeem ua kom sov ntau dhau.
