Nyob rau hauv lub xyoo pua 21st, human beings tau nkag mus rau hauv lub koom txoos cov ntaub ntawv. Hauv kev lag luam cov ntaub ntawv, pcb yog ib qho tseem ceeb ntawm cov ncej.
Cov khoom siv hluav taws xob yuav tsum muaj kev ua tau zoo, kev kub ceev thiab lub teeb thiab nyias, thiab kev lag luam ntau txoj haujlwm - PCB yog qhov tseem ceeb tshaj plaws rau kev siv tshuab hluav taws xob. Ntawm cov khoom PCB, nruj, yoog, nplaum-flex bonded multi-layer boards, thiab module substrates rau IC pob uas ua tau zoo rau cov khoom siv high-end. PCB kev lag luam plays lub luag haujlwm tseem ceeb hauv kev siv tshuab hluav taws xob.
Recalling cov lus teb nyuaj ntawm Tuam Tshoj tus PCB hauv 50 xyoo dhau los, hnub no nws tau sau ib daim ntawv zoo kawg nkaus hauv keeb kwm ntawm PCB txoj kev loj hlob hauv lub ntiaj teb. Nyob rau hauv 2006, Tuam Tshoj tus PCB cov nqi tsim nqi ze li ntawm 13 billion US dollars, lub npe hu ua lub ntiaj teb coob PCB lub teb chaws.
Nrog rau kev txhim kho kev sib tw ntawm PCB technology, Kuv muaj cov ntsiab lus hauv qab no:
Ua ntej, raws txoj kev ntawm kev sib txuas ntawm kev sib txuas siab (HDI)
Txij li thaum HDI ua kom zoo dua rau cov khoom siv siab tshaj plaws ntawm PCBs, nws nqa nplua xaim thiab micro-qhib rau PCB. HDI multi-layer daim ntawv thov lub davhlau ya nyob twg hluav taws xob - lub xov tooj txawb (lub xov tooj ntawm tes) yog tus qauv ntawm HDI frontier development technology. Nyob rau hauv lub xov tooj ntawm tes, cov xov tooj ntawm PCB lub rooj tsav khoom (50 μ m txog 75 μ m / 50 μ m rau 75 μ m, hlau dav / pitch) tau rais los ua lub hauv paus, thiab cov txheej txheem thiab cov phaj thickness yog thinned ; cov qauv siv hluav taws xob ua qauv yog miniaturized, uas nqa high ntom thiab kev ua tau zoo ntawm cov cuab yeej hluav taws xob. .
Rau ntau tshaj 20 xyoo, HDI tau txhawb txoj kev tsim cov xov tooj ntawm tes, thiab kev tsim cov LSI thiab CSP chips (pob) rau ntim thiab tswj kev ua haujlwm kom yooj yim, thiab kev tsim cov qauv kev sib tw rau cov ntawv ntim kuj tau nce qib ntawm PCBs. Yog li, nws yuav tsum ua raws li txoj kev ntawm HDI.
Thib ob, txoj kev siv tshuab ua lub tshuab muaj zog loj
Kev tsim ntawm cov khoom siv hluav taws xob (hu ua active components), hluav taws xob (hu ua passive components) lossis passive tivthaiv hauv cov txheej txheem ntawm PCB tau ua cov khoom loj. Cov tivthaiv npog tshuab yog PCB qhov kev ua haujlwm nrog cov khoom siv. Cov kev hloov loj, tab sis yuav tsum tsim kho cov qauv siv analog tsim, kev siv technology thiab kev soj ntsuam kom zoo, kev pov hwm kev ruaj ntseg yog qhov tseem ceeb tshaj plaws. Peb yuav tsum tau nqis peev pab ntxiv hauv lub nruab nrog tsim qauv, khoom siv, kev sim, thiab simulation kom muaj zog ntawm kev loj hlob.
Qhov peb, kev tsim cov ntaub ntawv hauv PCB yuav tsum ntxiv dua.
Txawm hais tias nws yog PCB los sis PCB khoom yooj yim, raws li lub ntiaj teb cov khoom hluav taws xob muaj lead-free, nws yuav tsum tau ua kom cov ntaub ntawv no ntau dua kom sov. Yog li, tus tshiab siab Tg, me me thermal expansion coefficient, me me dielectric qhov chaw, thiab dielectric zoo poob tangent yog cov khoom zoo heev, thiab cia tshwm.
Qeb plaub, txoj kev cia siab ntawm photovoltaic PCB yog sab
Nws siv txoj kab kev kho qhov dav thiab lub txheej txheem Circuit Court rau xa cov teeb meem. Qhov tseem ceeb rau qhov kev siv tshuab tshiab yog qhov kev tsim ntawm cov kab tsim kho kab (optical waveguide layers). Nws yog ib qho organic polymer tsim los ntawm lithographic photolithography, laser ablation, reactive ion etching, thiab cov zoo li. Tam sim no, technology tau industrialized hauv Nyiv, Tebchaws Asmeskas, thiab cov zoo li no.
Thib tsib, cov txheej txheem tsim yuav tsum raug muab kho, thiab cov cuab yeej siv siab tshaj yuav tsum tau pib.
1.Xam khoom ua tiav
HDI raug tsim muaj thiab zoo tuaj. Nrog rau txoj kev tsim kho PCB, tab sis cov qauv kev ua qoob ua lag luam tseem sib tua, cov nqi qis dua xws li cov khoom siv ntxiv thiab cov khoom siv roj ntxiv tau pib. Kev siv cov nanotechnology los mus ua kom tau lub qhov taub thaum tsim tus qauv PCB. Siab kev cia siab, kev luam ntawv zoo, inkjet PCB txheej txheem.
2. Cov khoom siv advanced
Zus tau zoo ntawm cov xov hlau, cov high-resolution photomasks thiab cov cuab yeej siv, thiab cov laser ncaj qha tuaj.
