Lub Sijhawm Tshiab Rau Automotive PCB Txoj Kev Loj Hlob?

Tsis muaj lub tsheb tshiab tuaj yeem ua haujlwm yam tsis muaj lub khoos phis tawj ntawm lub rooj tsavxwm uas yuav tsum tau siv lub tshuab luam ntawv sib txuas ua ke kom ua haujlwm. Hauv tsab xov xwm no, peb yuav tham txog automotive PCBs thiab lawv cov ntawv thov. Thov nyeem qhov peb tau npaj hauv qab no kom paub ntau ntxiv txog automotive PCBs.

Cov cib fim tshiab rau automotive PCB

Keeb kwm, tus nqi ntawm automotive electronics tau txuas ntxiv mus, thiab cov qauv yuav txuas ntxiv mus. Qhov kev faib ua feem ntawm automotive electronics nyob rau hauv lub zog tshiab tsheb tau mus txog 65 feem pua, uas yog ho siab dua li ntawm cov roj tsheb. Kev txhim kho txuas ntxiv ntawm kev siv hluav taws xob hauv tsheb yuav ua rau muaj kev loj hlob ntawm kev thov rau nws cov khoom tseem ceeb, PCB. Automotive PCBs yog siv rau hauv kev tswj cov tshuab, audio-visual systems, GPS modules, thiab lwm yam. Nyob rau hauv lub neej yav tom ntej, tsav los ntawm lub tshiab plaub modernizations ntawm lub tsheb, tus nqi ntawm ib lub tsheb yuav tsum tau nce ntau, tsav tag nrho cov lag luam loj mus ntxiv. loj hlob.

5G nrawm nrawm nkag mus hauv Is Taws Nem ntawm Tsheb, txuas ntxiv qhib qhov chaw loj hlob ntawm tsheb PCBs. Raws li lub koom haum kwv yees, los ntawm 2025, lub ntiaj teb no automotive PCB tso zis tus nqi yuav ntau tshaj 100 billion yuan, nrog ib tug compound kev loj hlob ntawm kwv yees li 15 feem pua ​​ntawm 2021 txog 2025. Lub upstream tooj liab clad laminate ntawm PCB account rau txog 30 feem pua ​​ntawm tag nrho cov nqi. . Tam sim no, tus nqi ntawm cov tooj liab thiab epoxy resin tau ruaj khov los yog poob qis, uas xav tias yuav yooj yim rau cov tuam txhab PCB. Cov tuam txhab tsim PCB hauv tsev tau nthuav dav ntau lawm los daws cov kev xav tau yav tom ntej, thiab kev txhim kho tag nrho ntawm kev lag luam yog vam meej.

Cov nplai ntawm kev lag luam automotive PCB tau nce

PCBs tau siv dav hauv tsheb, thiab tsheb kuj yog ib qho tseem ceeb hauv cheeb tsam ntawm PCBs. Raws li kev txhawb nqa ntawm cov khoom siv hluav taws xob, PCBs feem ntau yog siv hauv kev tswj fais fab, lub cev sensors, navigation systems, entertainment systems, thiab navigation systems nyob rau hauv tsoos tsheb. Los ntawm qhov kev xav ntawm PCB kev lag luam, hauv 2020, tsheb tau dhau los ua qhov thib ob loj tshaj plaws hauv cheeb tsam ntawm PCBs, suav txog li 16 feem pua.

Qhov kev thov rau automotive PCB pawg yog diversified, feem ntau. Cov kev cai ntawm tsheb rau PCB muaj ntau haiv neeg. Ib leeg thiab ob sab boards, 4- txheej boards, 6- txheej boards, thiab 8-16- txheej boards account rau 26.93 feem pua, 25.70 feem pua, thiab 17.37 feem pua, feem, accounting txog li 73 feem pua. nyob rau hauv tag nrho. HDI, FPC, IC carrier boards suav txog 9.56 feem pua, 14.57 feem pua, thiab 2.38 feem pua, raws li, suav txog li 27 feem pua ​​​​ntawm tag nrho. Nws tuaj yeem pom tias PCB multilayer boards tseem yog qhov kev thov tseem ceeb rau kev siv hluav taws xob hauv tsheb. Qhov kev thov rau tsheb PCB feem ntau yog 2-6 cov khaubncaws sab nraud povtseg, uas suav txog li 2 feem pua ​​​​ntawm cov nqi ntawm tag nrho cov tsheb hluav taws xob.

Dab tsi yog kev faib tawm ntawm automotive PCBs?

Raws li kev sib xyaw ua ke ntawm cov cuab yeej siv tshuab thiab hluav taws xob, cov cuab yeej siv tsheb niaj hnub ua ke nrog cov cuab yeej siv niaj hnub nrog kev tshawb fawb thiab thev naus laus zis tshiab. Cov khoom sib txawv nyob ntawm cov khoom siv hluav taws xob nrog cov haujlwm sib txawv, ua rau kev siv PCBs nrog cov haujlwm sib txawv.

Raws li qhov sib txawv ntawm PCB substrate cov ntaub ntawv rau tsheb, lawv tuaj yeem muab faib ua inorganic ceramic-based PCBs thiab organic resin-based PCBs. Cov yam ntxwv ntawm ceramic-raws li PCBs yog cov cua kub tsis kam thiab zoo heev dimension stability, haum rau lub cav tshuab hauv qhov kub thiab txias. Txawm li cas los xij, kev tsim khoom tsis zoo ntawm cov khoom siv ceramic-raws li PCBs ua rau cov nqi siab ntawm Circuit Court boards. Nrog rau kev tsim kho tshiab ntawm cov khoom siv hluav taws xob nrog cov hluav taws xob ntau dua, cov khoom siv PCBs feem ntau yog siv hauv cov tsheb niaj hnub no.
