Txij li xyoo 2021, tau muaj xov xwm nyob rau sab saud cov khoom siv hluav taws xob ua hluav taws xob ntawm cov khoom siv hluav taws xob uas cov neeg tsim khoom Nyij Pooj tau ploj mus. Poob rau qhov kev sib tw ntawm Suav teb av loj thiab Taiwan cov chaw tsim khoom, cov chaw tsim khoom Nyij Pooj txo qis cov khoom lag luam ntawm alumina ceramic substrates, tsuas yog ua haujlwm rau cov neeg siv khoom mus sij hawm ntev hauv Nyij Pooj, thiab hloov pauv peev txheej rau aluminium nitride substrates thiab lwm yam ntawv thov. Kev lag luam cia siab tias cov tuam txhab Suav yuav ua kom zoo dua ntawm kev hloov pauv hloov pauv, thiab cov khoom siv hauv pem teb tseem yuav nkag mus rau lub hnub nyoog kub oligopolistic.
Ceramic substrates suav txog 20% ntawm tus nqi ntawm cov tshuaj tiv thaiv nti thiab yog cov khoom siv tseem ceeb. Hauv 30 xyoo dhau los, vim muaj kev sib tw hnyav hauv kev lag luam nti resistor, cov chaw tsim khoom tiv thaiv tau tawm tsam kev sib tw tawm tsam, uas tau ua rau cov dej ntws saum toj kawg nkaus ceramic substrate muab cov saw kom ntsib kev poob siab. Tam sim no, cov khoom siv tseem ceeb sab nraum Suav suav nrog Chaozhou Sanhuan, Jiuhao, Hokuriku, Maruwa thiab lwm cov chaw tsim khoom.
Nws tau tshaj tawm hauv kev lag luam uas cov neeg tsim khoom Nyij Pooj tau nrawm dua qhov ploj ntawm alumina substrates txij li xyoo tas los vim yog kev sib tw siab los ntawm Tuam Tshoj thaj av loj thiab Taiwan tuam ntxhab. Cov ntim khoom tau poob qis los ntawm 10 lab daim hauv ib lub hlis rau 3 txog 4 lab daim, tsuas yog muaj peev xwm ntau lawm. Nws tsuas yog ua haujlwm tshwj xeeb rau cov neeg siv khoom lag luam cog lus ntev hauv Nyij Pooj. Xyoo tas los, lub Hoobkas tseem muab tus nqi txiav los tshem cov khoom muag, thiab nws cov peev txheej tsim khoom hloov mus rau cov khoom nyuaj xws li txhuas nitride. Hauv qhov no, lub tuam txhab tiv thaiv tsis xav tsis thoob los ntawm kev txhob txwm tso tawm ntawm cov chaw tsim khoom Nyij Pooj, qhia tias kev thim rov qab ntawm cov khoom lag luam Japanese ceramic substrate yog qhov teeb meem ntawm lub sijhawm.
Kev lag luam ceramic substrate yog qhov tshwj xeeb. Hauv qhov chaw muaj kev sib tw hnyav, yog tias tsis muaj kev lees paub los ntawm cov nqes hluav taws xob tiv thaiv cov chaw tsim khoom, feem ntau ntawm cov chaw tsim hluav taws xob ceramic tsis txaus siab los nqis peev hauv kev nthuav dav. Yog li ntawd, kev hloov pauv ntawm cov khoom lag luam ceramic txheej txheem yog ib txwm muaj, thiab cov qauv ntawm oligopoly hla dhau wafers. Hauv kev lag luam tsis kam, tag nrho kev lag luam thoob ntiaj teb ntawm cov khoom lag luam nti hauv Taiwan, Tuam Tshoj yog li 70-80%. Tag nrho cov tooj liab hauv ntiaj teb' Chaozhou Sanhuan loj tshaj thiab thib ob loj tshaj Jiuhao suav txog li 65-75% ntawm kev lag luam thoob ntiaj teb. Tam sim no tias cov tuam txhab Nyij Pooj tau ploj mus, cov oligopoly yuav ntxiv dag zog.
UNIPRETEC tseem tabtom nquag siv ua haujlwm ntsig txog. Ib txoj kab tshiab alumina substrate ntau lawm uas peb lub tuam txhab tau nqis peev hauv nruab nrab-2021 thiab yuav sai sai no tsim cov peev txheej ruaj khov hauv peb lub hlis tom ntej.
