Dab tsi yog plaub cov ntaub ntawv tseem ceeb hauv PCB kev lag luam saw thiab cov tuam txhab muaj feem cuam tshuam?
PCBs, uas yog ib qho tseem ceeb rau kev sib txuas ntawm cov khoom siv hluav taws xob sib txuas, tau siv dav hauv cov cuab yeej sib txuas lus, AI servers, lub zog tshiab, kev tswj hwm kev lag luam, thiab kev sib koom ua ke ntawm cov khoom siv hluav taws xob. Lub hauv paus ntawm kev lag luam txoj kev loj hlob yog nyob rau hauv cov ntaub ntawv raw khoom, feem ntau yog plaub pawg: tooj liab-clad laminates (CCLs), tooj liab ntawv ci, hluav taws xob fiberglass daim ntaub, thiab epoxy resin. Cov no kuj yog qhov tseem ceeb ntawm kev ua tiav kev hloov pauv hauv tsev hauv siab - kawg, siab - zaus, thiab siab -PCBs ceev. Nrog rau kev nce ntxiv hauv AI suav lub zog, qhov kev thov rau siab -kawg PCBs tau nce siab, ua kom cov thev naus laus zis rov ua dua thiab muaj peev xwm nthuav dav hauv cov ntaub ntawv tseem ceeb. Cov tuam txhab ua lag luam nyob rau hauv ntau yam sub-sectors tab tom siv lawv cov teeb meem thev naus laus zis, kev tsim khoom lag luam, thiab cov ntawv pov thawj cov neeg siv khoom kom tau txais txiaj ntsig kev lag luam.
1. Copper-Clad Laminates (CCLs): CCLs yog lub hauv paus tseem ceeb rau PCB kev tsim khoom thiab qhov tseem ceeb ntawm kev txiav txim siab PCB kev ua tau zoo, ua rau lawv yog lub hauv paus ntawm PCB kev lag luam. Kev txhim kho kev lag luam tam sim no tsom mus rau peb txoj kab tseem ceeb: siab- zaus, siab- cov boards ceev, IC substrate- cov ntaub ntawv tshwj xeeb, thiab dav dav -lub hom phiaj FR-4 cov boards yooj yim. Ntawm cov no, siab - zaus, siab - ceev CCLs siv nyob rau hauv AI servers, high-end kev sib txuas lus keyboards, thiab optical modules tau dhau los ua qhov tseem ceeb ntawm kev lag luam kev sib tw.
ShengYi Technology, raws li tus thawj coj ntawm CCLs hauv tsev, tuav ib qho chaw hauv qib thib ob hauv ntiaj teb. Nanya Cov Khoom Siv Tshiab tau ua tiav cov thawj coj thev naus laus zis hauv kev tsim khoom hauv tsev siab - zaus, siab - ceev M8 thiab M9 cov khoom lag luam, sib koom ua ke nrog cov PCB thiab AI server manufacturers, thiab yog tus xa khoom tseem ceeb ntawm siab - kawg kev sib txuas lus thiab kev siv khoom siv. Kev tsom mus rau qhov siab - zaus, siab- ceev tooj liab- clad laminate (CCL) kev ua lag luam, nws cov M-series cov khoom tau ua tiav cov ntawv pov thawj thiab cov khoom lag luam zoo matrix, meej meej lub hom phiaj siab -kev loj hlob daim ntawv thov xws li modules AI servers. Huazheng Cov Khoom Tshiab tshwj xeeb hauv siab-kawg substrates thiab IC substrate cov ntaub ntawv, ua kom pom kev ua haujlwm zoo nyob rau hauv siab - zaus, siab - ceev boards thiab hlau substrates, ntse nkag mus rau hauv cov khoom tseem ceeb ntawm kev ntim khoom thiab kev suav PCBs. Jinan Guoji tsom rau nruab nrab- tuab FR-4 dav dav- lub hom phiaj CCLs, siv nws lub peev xwm tsim khoom loj thiab tus nqi zoo los ua kom nws cov lag luam tseem ceeb thaum tsis tu ncua mus rau siab - zaus, siab - nrawm, thiab cov khoom lag luam qib siab.
2. Copper Foil Copper foil yog qhov tseem ceeb ntawm CCLs, suav txog qhov feem ntau ntawm cov khoom siv raw, thiab muab faib ua ob pawg: PCB hluav taws xob hluav taws xob hluav taws xob hluav taws xob tooj liab ntawv ci thiab lithium roj teeb tooj liab ntawv ci. AI suav kho vajtse tso cov kev cai nruj rau PCB tooj liab ntawv ci, xav tau qis profile, ultra- nyias qhov ntev, siab kub tsis kam, thiab tsis tshua muaj hluav taws xob tsis tu ncua. High-end HVLP thiab RTF series tooj liab foils tau dhau los ua kev lag luam tsim nyog, thiab siab-kawg tooj liab tau dhau los ua qhov tseem ceeb rau kev hloov pauv hauv tsev hauv cov saw hlau.
Tongguan Copper Foil, txhawb nqa los ntawm kev ua tiav kev lag luam ntawm Tongling Nonferrous Metals, yog ib lub tuam txhab ua lag luam hauv PCB hluav taws xob tooj liab. Nws lub siab -HVLP kawg series tau ua tiav qhov loj - teev ntau lawm, sib sib zog nqus ua ke nrog cov thawj coj tooj liab- clad laminate thiab AI mov saw manufacturers. Defu Technology muaj dual -khiav tawm tswv yim nyob rau hauv PCB thiab lithium roj teeb tooj liab ntawv ci, ntse nkag mus rau AI server mov saw nrog nws siab -kawg HVLP tooj liab ntawv ci, ua rau kev lag luam nyob rau hauv ob qho tib si technology thiab ntau lawm muaj peev xwm. Nord Copper thiab Jiayuan Technology, ntev -tsim cov thawj coj hauv lithium roj teeb tooj liab ntawv ci, muaj ob qho tib si ventured mus rau hauv siab -kawg PCB hluav taws xob tooj liab ntawv ci, leveraging lawv ultra-thin tshwj xeeb tooj liab ntawv ci thev naus laus zis los txeeb lub siab -kawg lag luam. Tsis tas li ntawd, Zhongyi Technology thiab Yihao Cov Khoom Siv Tshiab, nrog rau lawv ob qho - kev lag luam layout thiab kev ua kom muaj peev xwm ua tau zoo, tau nce sai hauv PCB circuit tooj liab ntawv ci sector, muab ntau yam PCB manufacturers.
3. Electronic Fiber Cloth Electronic-qibfiberglass ntaubyog lub hauv paus ntsiab lus ntawm tooj liab-clad laminates (CCLs), feem ntau muab PCBs nrog rwb thaiv tsev, cov qauv rigidity, tsawg expansion tus nqi, thiab tsawg dielectric zog. Kev loj hlob tawg ntawm AI siab - zaus thiab siab -PCBs ceev tau ua rau muaj kev xav tau rau ultra-nyias, ultra- nyias, qis-dielectric, thiab qis-thermal- nthuav dav-coefficient} ua hluav taws xob siab{10} siab-kev loj hlob sub- ntu ntawm fiberglass kev lag luam.
Honghe Technology yog tus thawj coj thoob ntiaj teb hauv ultra-nyias thiab ultra-nyias siab-kawg hluav taws xob ntaub. Nws cov khoom qis -dielectric zoo kawg nkaus ua tau zoo nrog AI siab- zaus thiab siab- ceev boards thiab tau txais ntawv pov thawj los ntawm cov thawj coj thoob ntiaj teb kev lag luam fais fab, muab nws qhov txiaj ntsig zoo sib tw. Tuam Tshoj Jushi, raws li tus thawj coj ntawm lub ntiaj teb fiberglass kev lag luam, muaj qhov zoo ntawm cov nplai, nqi, thiab thev naus laus zis hauv cov xov paj hluav taws xob thiab cov ntaub ntawv hluav taws xob, npog txhua pawg ntawm cov pa thiab siab -kawg qis-dielectric electronic cloths. Feilihua tshwj xeeb hauv quartz hluav taws xob daim ntaub thiab cov fiberglass tshwj xeeb, nrog cov khoom tsim nyog rau ultra- siab- zaus CCLs thiab cov xwm txheej ntim siab heev, qhia txog nws qhov zoo sib txawv. International Composites thiab Taishan Fiberglass, ib lub koom haum ntawm Sinoma Science & Technology, yog ob qho tib si tseem ceeb ntawm cov khoom siv hluav taws xob - qib fiberglass, tsis tu ncua muab kev pabcuam ruaj khov rau CCL kev lag luam saw.
4. Resins: Epoxy resins thiab tshwj xeeb resins yog cov tub ntxhais sib txuas cov neeg ua haujlwm rau tooj liab -clad laminates (CCLs), ncaj qha txiav txim siab dielectric zog, kub tsis kam, thiab ruaj khov ntawm cov khoom siv PCB. General-Lub hom phiaj PCBs feem ntau siv cov epoxy resins zoo tib yam, thaum siab-kawg siab- zaus thiab siab-ceev PCBs cia siab rau siab-kawg resins xws li PPO, hydrocarbon resins, BMI, thiab qis-dielectric tshwj xeeb epoxy resins. Qhov kev lag luam no tau ntev tau monopolized los ntawm cov tuam txhab txawv teb chaws, tab sis kev hloov pauv hauv tsev tam sim no nrawm dua.
Hongchang Electronics, lub tuam txhab ua lag luam hauv hluav taws xob- qib epoxy resins, tau tsim dual -lub ntsiab- kev lag luam qauv ntawm cov resins thiab CCLs. Nws qhov siab -kawg epoxy cov khoom tau sib xws nrog ntau yam siab - zaus thiab siab - ceev CCL cov txheej txheem ntau lawm. Dongcai Technology tau ua tiav cov txiaj ntsig tseem ceeb hauv kev ua haujlwm siab - zaus thiab siab -cov khoom siv hluav taws xob ceev ceev, rhuav tshem cov kev lag luam txawv teb chaws nrog cov khoom siv siab - kawg xws li M9- qib hydrocarbon resins thiab nkag mus rau AI siab - cov khoom siv kawg. Shengquan Group, ib lub tuam txhab ntev - tau tsim lub tuam txhab nyob rau hauv kev lag luam hluavtaws cob, ua rau hauv hluav taws xob-qib PPO, phenolic resins, thiab tshwj xeeb epoxy technologies, thiab yog ib tug tseem ceeb resin tsum rau domestic CCL tuam txhab uas muag.
Zuag qhia tag nrho, AI xam lub zog nthwv dej yog hloov kho cov khoom lag luam PCB. Plaub cov ntaub ntawv tseem ceeb nce mus txog- tooj liab- clad laminates, copper foil, electronic fabric, and specialty resins- sawv cev rau ob qho tib si lub fwj thiab lub cib fim zoo tshaj plaws rau kev txhim kho kev lag luam. Nrog rau kev nrawm ntawm kev hloov pauv hauv tsev ntawm siab- cov ntaub ntawv PCB kawg, cov tuam txhab ua lag luam hauv niche ntu nrog qhov zoo hauv kev tshawb fawb thiab kev tsim kho tshuab, ntawv pov thawj cov neeg siv khoom, thiab cov peev txheej tsim khoom yuav txuas ntxiv txaus siab rau cov txiaj ntsig ntawm kev lag luam kev vam meej thiab dhau los ua qhov txuas txuas nrog tus nqi loj tshaj plaws hauv PCB kev lag luam saw.
