Taw qhia rau High Density Printed Circuit Board

Printed circuit boards yog cov khoom tsim los ntawm cov ntaub ntawv insulating ntxiv los ntawm cov neeg xyuas pib thaiv. Thaum ua cov khoom kawg, integrated circuits, transistors, diodes, passive Cheebtsam, thiab ntau lwm yam hluav taws xob Cheebtsam yog ntsia rau nws. Los ntawm kev sib txuas ntawm cov xov hlau, cov teeb liab hluav taws xob sib txuas thiab kev ua haujlwm tuaj yeem tsim. Yog li ntawd, cov ntawv luam tawm Circuit Board yog lub platform uas muab cov khoom sib txuas, ua lub hauv paus rau kev sib txuas cov khoom.

Vim qhov tseeb tias cov ntawv luam tawm Circuit Board tsis yog cov khoom siv dav dav, lub ntsiab lus ntawm lawv cov npe yog me ntsis ruam. Piv txwv li, motherboards siv nyob rau hauv tus kheej lub computer yog hu ua motherboards thiab tsis tuaj yeem raug xa ncaj qha mus rau cov ntawv luam tawm Circuit Board. Txawm hais tias muaj cov laug cam hauv motherboard, lawv tsis zoo ib yam. Yog li ntawd, thaum ntsuas kev lag luam, nws tsis tuaj yeem hais tias ob qho tib si cuam tshuam tab sis tsis tuaj yeem hais tias yog tib yam. Piv txwv li, vim tias muaj cov khoom sib xyaw ua ke ntawm lub rooj tsav xwm hauv Circuit Court, cov xov xwm xov xwm hais txog nws ua IC pawg thawj coj saib, tab sis qhov tseeb, nws tsis zoo li lub rooj tsav xwm luam tawm.

Nrog rau qhov sib txawv ntawm cov khoom siv hluav taws xob ntau thiab cov khoom siv hluav taws xob, kev sib cuag ntawm cov khoom siv hluav taws xob sib xyaw ua ke raug txo, thiab qhov ceev ntawm cov teeb liab kis tau tus mob nce ntxiv. Qhov no ua rau muaj qhov nce ntawm cov kev sib txuas thiab kev txo qis hauv cheeb tsam ntawm qhov ntev ntawm inter point wiring. Cov no yuav tsum tau siv cov kev sib txuas ntawm cov kab hluav taws xob siab thiab micropore thev naus laus zis kom ua tiav lub hom phiaj. Kev xaim thiab kev sib txuas yog qhov nyuaj rau kev ua tiav rau ib leeg thiab ob sab boards, ua rau cov ntawv luam tawm hauv Circuit Court ua ntau txheej. Tsis tas li ntawd, vim qhov nce ntxiv ntawm cov teeb liab kab, ntau lub zog txheej thiab cov dav hlau hauv av yog qhov tsim nyog ntawm kev tsim, txhua yam uas ua rau txheej txheej luam tawm ntau dua.

Rau cov kev xav tau hluav taws xob ntawm cov teeb liab ceev, cov ntawv luam tawm hauv Circuit Court yuav tsum muaj kev tswj xyuas impedance nrog AC yam ntxwv, muaj peev xwm kis tau tus mob siab, thiab txo qis hluav taws xob tsis tsim nyog (EMI). Kev siv cov qauv ntawm stripline thiab microstrip, ntau txheej txheej tsim tsim nyog. Yuav kom txo tau qhov teeb meem zoo ntawm cov teeb liab kis tau tus mob, tsawg dielectric yuav raug saws. Txhawm rau ua kom tau raws li cov khoom siv me me thiab cov khoom siv hluav taws xob, qhov ntom ntom ntawm cov ntawv luam tawm Circuit Board tseem yuav tau nce ntxiv kom tau raws li qhov xav tau. Qhov tshwm sim ntawm cov txheej txheem sib dhos rau cov khoom xws li BGA, CSP, thiab DCA (Direct Chip Attachment) tau txhawb nqa cov ntawv luam tawm hauv Circuit Court boards mus rau qhov tsis tau pom dua los ntawm high-density.

Qhov nrog ib txoj kab uas hla tsawg dua 150um yog hu ua micropores hauv kev lag luam. Cov kab hluav taws xob ua los ntawm kev siv cov tshuab geometric qauv ntawm cov micropores tuaj yeem txhim kho kev ua tau zoo ntawm kev sib dhos, kev siv qhov chaw, thiab lwm yam. Nyob rau tib lub sijhawm, nws tseem tsim nyog rau miniaturization ntawm cov khoom siv hluav taws xob.

Muaj ntau lub npe sib txawv hauv kev lag luam rau cov khoom lag luam luam tawm nrog cov qauv no. Piv txwv li, cov tuam txhab European thiab Asmeskas tau siv los xa mus rau cov khoom lag luam no raws li SBUs vim yog kev siv cov txheej txheem tsim ua ntu zus hauv lawv cov kev pabcuam, uas feem ntau txhais tau tias yog "txoj kev txheej txheej txheej". Raws li rau Japanese manufacturers, vim hais tias lub pore qauv tsim los ntawm cov khoom no ntau npaum li cas me dua yav dhau los, cov khoom siv technology ntawm cov khoom no hu ua MVP. Qee tus neeg kuj tseem xa mus rau cov rooj tsav xwm ntau yam xws li MLB (Multilayer Board), yog li lawv xa mus rau cov ntawv luam tawm Circuit Board li BUM.

Lub koom haum IPC Circuit Board hauv Tebchaws Meskas, raws li kev txiav txim siab kom tsis txhob muaj kev ntxhov siab, tau thov kom xa mus rau hom khoom no raws li lub npe thoob ntiaj teb rau HDI. Yog hais tias txhais ncaj qha, nws yuav dhau los ua cov cuab yeej sib txuas siab. Txawm li cas los xij, qhov no tsis tuaj yeem cuam tshuam cov yam ntxwv ntawm cov ntawv luam tawm Circuit Board, yog li feem ntau cov tuam txhab pcb xa mus rau cov khoom xws li HDI boards lossis tag nrho Suav lub npe "high-density interconnect technology". Txawm li cas los xij, vim yog qhov teeb meem ntawm kev hais lus zoo, qee tus neeg ncaj qha xa mus rau cov khoom xws li "high-density circuit boards" lossis HDI boards.
