Chifukwa chiyani opanga ambiri a PCB amakweza mtengo mu 2021?

——Zifukwa zokwezera mtengo wa PCB.

Mwachidule:

Mu 2021, chuma chapadziko lonse lapansi chasokonekera kwambiri chifukwa cha zovuta za mliriwu.Kwa makampani onse a zamagetsi, 2020 si chaka chovuta kwambiri, ndipo 2021 ndiye chiyambi cha nthawi yovuta kwambiri.

Chifukwa cha COVID-19, zida zofunika kwambiri zopangira PCB monga mipira yamkuwa, zojambula zamkuwa, zotchingira zamkuwa, ma epoxy resins, ndi ulusi wagalasi zapitilira kukwera, zomwe zidapangitsa kuti mtengo wopanga PCB ndi msonkhano wa PCB ukwere.

Chonde onani pansipa Chithunzi 1: Mtengo wamalonda wa Copper

Pansipa tiwona chifukwa chake mtengo wazinthu za PCB ukuwonjezeka:

1. Copper ndi copper zojambulazo

Ndi kufalikira kwa COVID-19 mu 2020, mayiko ambiri adatseka.Anthu atabwerera kuntchito, kufunikira koponderezedwa kudayamba kupitilira mphamvu yopanga, zomwe zidapangitsa kuti pakhale kufunikira kwa zojambula zamkuwa zopangira ma PCB ndi mabatire azinthu zamagetsi zamagetsi, zomwe zimapangitsa kuti mitengo ichuluke.Nthawi yowonjezereka yobweretsera idapangitsanso kukwera kwamitengo (Onani Gulu 1).Pa nthawi yomweyo, chifukwa cha opanga mkuwa zojambulazo kutembenuzira mphamvu zawo kukulitsa kupanga opindulitsa lifiyamu batire mkuwa zojambulazo, makamaka zakuda zakuda zamkuwa (2 OZ/70 microns kapena kuposa).Iwo pang'onopang'ono kutembenukira kwa magetsi galimoto lifiyamu batire kupanga, izi zakhala ndi zotsatira extrusion pa mphamvu yopanga PCB mkuwa zojambulazo, ndipo zinachititsa mtengo wa zamagetsi mkuwa zojambulazo kwa PCB kuuluka (Onani Table 2).Pakadali pano, mtengo wamkuwa ndi 50% wokwera kuposa wotsika kwambiri mu 2020.

Table 1: Kugwiritsa ntchito mphamvu zazitsulo zamkuwa (kukula kofunikira) mu 2020

Gulu 2: Kufuna kwa China kwa mabatire a lithiamu pamagalimoto amagetsi 2020 mpaka 2030

2. Epoxy utomoni

Kufuna kwa China kwa ma epoxy resin pakugwiritsa ntchito mphamvu zobiriwira (tsamba la turbine) kukupitilira kukwera.Pa nthawi yomweyo, zotsatira za ngozi mafakitale lalikulu epoxy utomoni kupanga zomera ku China ndi Korea zachititsa PCB mkuwa atavala laminate opanga anakumana kusowa kotunga m'miyezi iwiri yapitayi, ndipo mitengo anakwera kwambiri ndi mpaka 60%.Zotsatira zake zimawonekera makamaka pakukwera kwamitengo yamafuta amtundu wa FR-4 ndi prepregs.Mu Disembala 2020, ma FR-4 laminates ndi prepregs adakwera ndi 15% -20%.

3. Glass fiber

Kukula kofulumira kwa kugwiritsidwa ntchito ndi kugwiritsa ntchito mphamvu zobiriwira kwapangitsanso mitengo yagalasi yagalasi ndi nsalu zamagalasi, makamaka kuletsa kuperekedwa kwa nsalu zolemera monga mtundu 7628 ndi mtundu wa 2116. Opanga magalasi opangira magalasi nawonso amakonda kukwaniritsa zofuna zamakampani ena omwe ndi otsika. zofunika khalidwe ndi apamwamba mitengo msika kuposa makampani PCB.PCB copper clad laminate opanga amayerekezera kuti mchitidwe adzachititsa kusowa kwambiri mkuwa atavala laminate mphamvu kupanga, makamaka olimba zipangizo.

Chidule

Kuyambira 2020, PCB kupanga zinthu zopangira monga CCL (copper clad laminate), PP (prepreg), ndi zojambula zamkuwa zakhala zikusoweka, ndipo mitengo yogula ikupitilira kukwera.Kuphatikiza apo, iyenera kukhala pamzere kuti igule pamitengo yokwera, ndipo zida zina zosagwirizana ndizovuta kugula.

Mkati mwa theka la chaka, PCBFuture inalandira zidziwitso za kuwonjezeka kwa mitengo ya 5 kuchokera kwa ogulitsa CCL.Mwa iwo, Shengyi adakwera ndi 63%, zojambula zamkuwa zidakwera ndi 55%, ndipo mipira yamkuwa idakwera kuchoka pa 35300 chaka chatha kufika pa 64320 yamakono, kuchuluka kwa 83.22%, malata adakwera ndi 20,000 yuan/ton, ndipo palladium. madzi adakwera ndi 34.5%…

Kwa ogwiritsa ntchito magetsi otsika, zomwe zili pamwambazi zikuwonjeza mitengo sizipangitsa aliyense kumva chisoni.M'chaka chathachi, pofuna kusunga kukhazikika kwamitengo, PCBFuture yakhala ikukumana ndi zotsatira za kukwera kwa mitengo kuchokera kumtunda wamtengo wapatali wogulitsa okha.Ndipo makasitomala athu sanamvepo kukakamizidwa koguliraPCB ndi PCBA.

Malinga ndi mfundo PCBfuture a zogwirizana, pamene zinthu mtengo waKupanga kwa PCBkukwera kapenaturnkey PCB msonkhano zigawokukwera, tidzayika patsogolo kuwongolera magwiridwe antchito amkati, kukulitsa chiwongola dzanja choyamba, kuchepetsa zotsalira ndikuchepetsa ndalama zowongolera momwe tingathere kuti tithane ndi vuto la kukwera mtengo komanso kusunga magwiridwe antchito abizinesi.
