Yuav ua li cas to taub qhov txawv ntawm HDI board thiab zoo tib yam PCB

Taw qhia ntawm HDI board

HDI board (High Density Interconnector), uas yog, high-density interconnection board, yog ib lub rooj tsav xwm Circuit Court nrog ib tug kuj high line faib ceev siv micro-dig muag thiab faus los ntawm technology. Lub Rooj Tswjhwm Saib HDI muaj cov kab sab hauv thiab txheej txheej txheej, thiab tom qab ntawd siv qhov drilling, hauv-qhov metallization thiab lwm yam txheej txheem kom paub txog kev sib txuas sab hauv ntawm txhua txheej kab.

HDI boards feem ntau yog tsim los ntawm txoj kev lamination. Qhov ntau tus naj npawb ntawm laminations, qhov siab dua ntawm cov txheej txheem ntawm lub rooj tsavxwm. Ordinary HDI boards yog ib qho kev tsim ib zaug, thiab high-end HDI siv ob lossis ntau qhov kev tsim thev naus laus zis, thaum siv cov thev naus laus zis PCB xws li stackup, electroplating, thiab laser ncaj qha drilling.

Thaum qhov ceev ntawm PCB nce ntau tshaj li yim-txheej board, tus nqi ntawm kev siv HDI yuav qis dua li ntawm cov txheej txheem lamination complex. HDI pawg thawj coj saib yog qhov tsim nyog rau kev siv cov tshuab ntim khoom siab heev, thiab nws cov khoom siv hluav taws xob thiab cov teeb liab raug siab dua li cov PCBs. Tsis tas li ntawd, HDI board muaj kev txhim kho zoo dua rau kev cuam tshuam hauv xov tooj cua, electromagnetic yoj cuam tshuam, electrostatic paug, thermal conduction, thiab lwm yam.

Cov khoom siv hluav taws xob tas li txhim kho mus rau qhov siab ceev thiab siab precision. Qhov hu ua "siab" tsis tsuas yog txhim kho kev ua haujlwm ntawm lub tshuab, tab sis kuj txo qhov loj ntawm lub tshuab. High Density Integration (HDI) thev naus laus zis ua rau ntau qhov me me ntawm cov khoom tsim khoom kawg thaum ua tau raws cov qauv siab dua rau kev ua haujlwm hluav taws xob thiab kev ua haujlwm zoo. Tam sim no cov khoom siv hluav taws xob nrov, xws li xov tooj ntawm tes, digital (lub koob yees duab) koob yees duab, phau ntawv computers, automotive electronics, thiab lwm yam, ntau siv HDI boards. Nrog rau kev kho dua tshiab ntawm cov khoom siv hluav taws xob thiab kev lag luam xav tau, kev txhim kho ntawm HDI boards yuav nrawm heev.

General PCB qhia

PCB (Printed Circuit Board), Suav lub npe yog luam tawm Circuit Board, tseem hu ua lub rooj tsav xwm luam tawm, yog ib qho tseem ceeb hauv hluav taws xob, lub cev txhawb nqa rau cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob. Vim tias nws yog tsim los siv hluav taws xob luam ntawv, nws yog hu ua "luam tawm" Circuit board.

Nws txoj haujlwm tseem ceeb yog kom tsis txhob muaj kev sib txuas ntawm cov ntawv xov xwm vim qhov sib xws ntawm cov ntawv luam tawm zoo sib xws tom qab cov khoom siv hluav taws xob tau txais cov ntawv luam tawm, thiab tuaj yeem paub qhov tsis siv neeg ntxig lossis tso cov khoom siv hluav taws xob, tsis siv neeg soldering, thiab tsis siv neeg tshawb nrhiav kom txhim kho cov khoom siv hluav taws xob zoo, txhim kho kev ua haujlwm ntawm kev ua haujlwm, txo cov nqi, thiab txhawb kev saib xyuas.

Puas yog PCB boards nrog qhov muag tsis pom thiab faus vias hu ua HDI boards?

HDI boards yog high-density interconnected circuit boards. Cov laug cam uas yog plated nrog qhov muag tsis pom qhov thiab tom qab ntawd nias dua yog tag nrho HDI boards. Lawv muab faib ua thawj zaug, thib ob, txiav txim thib peb, plaub-txiav, thiab thib tsib-txiav HDI. Piv txwv li, lub rooj tsav xwm tseem ceeb ntawm iPhone 6 yog thib tsib-txiav HDI.Simple faus vias tsis tas HDI.

Yuav ua li cas paub qhov txawv HDI PCB thawj zaug, thib ob thiab xaj thib peb

⑴ Thawj qhov kev txiav txim yog qhov yooj yim, thiab cov txheej txheem thiab txheej txheem yog yooj yim los tswj.

⑵ Cov kev txiav txim thib ob pib muaj teeb meem, ib qho yog qhov teeb meem sib dhos, thiab lwm qhov yog qhov teeb meem ntawm kev xuas nrig ntaus thiab tooj liab plating. Muaj ntau ntau hom kev txiav txim thib ob. Ib qho yog tias cov haujlwm ntawm txhua qhov kev txiav txim yog staggered. Thaum cov txheej txheem thib ob uas nyob ib sab yuav tsum tau txuas nrog, nws txuas nrog hauv nruab nrab txheej los ntawm cov xov hlau, uas yog sib npaug rau ob qhov kev txiav txim thawj HDI.

Qhov thib ob yog tias ob qhov kev txiav txim thawj zaug tau sib tshooj, thiab qhov thib ob-kev txiav txim yog pom tau los ntawm superposition. Kev ua haujlwm zoo ib yam li ob qhov kev txiav txim thawj zaug, tab sis muaj ntau yam txheej txheem uas yuav tsum tau tswj tshwj xeeb, uas tau hais los saum no.

⑶ Qhov thib peb yog punch ncaj qha los ntawm txheej txheej mus rau txheej thib peb (lossis N-2 txheej). Cov txheej txheem no txawv ntawm qhov dhau los, thiab qhov nyuaj ntawm kev xuas nrig ntaus kuj tseem ntau dua.

Qhov thib ob-order analogy yog tib yam rau qhov thib peb-order.

Qhov txawv ntawm HDI board thiab zoo tib yam PCB

Lub rooj tsav xwm PCB feem ntau yog FR-4, uas yog ua los ntawm epoxy resin thiab hluav taws xob-qib iav ntaub. Feem ntau, rau cov tsoos HDI, nplaum-rov qab tooj liab ntawv ci yog siv rau sab nrauv. Vim hais tias laser drilling tsis tuaj yeem nkag mus rau iav ntaub, nplaum-rov qab tooj liab ntawv ci yam tsis muaj iav fiber ntau. Txawm li cas los xij, tam sim no lub zog siab laser drilling rig tuaj yeem nkag mus rau 1180 iav ntaub. Qhov no tsis txawv ntawm cov khoom siv zoo tib yam.
