Ukwenyuka Kwezindleko ze-FR4 PCB Kwabakhiqizi Bezinto Zogesi

I-FR-4 — i-laminate elukiwe yengilazi ne-epoxy eyakhiwe phezu kwayo iningi lama-PCB emhlabeni — ibilokhu iyi-default ethembekile nengabizi kakhulu amashumi eminyaka. Ngo-2026 ngisho ne-FR-4 ibize kakhulu, futhi abathengi abaningi bamangala ukuthola ukuthi ibhodi elishibhile kakhulu, elivamile kakhulu kukhathalogi yabo libiza kakhulu kunangonyaka odlule. Ukuqonda ukuthi kungani impahla engekho enkingeni yangempela yezinto zokusetshenziswa okuluhlaza isakhuphuka ngentengo, nokuthi umenzi wezinto zikagesi angenzani ngakho, yikona okugxilwe kukho kulo mhlahlandlela.

Kungani Amanani e-FR4 Eqhubeka Ekhuphuka

Amanani e-FR-4 akhuphuke ngezizathu ezimbili ezihlukile, futhi kuyasiza ukuwahlukanisa. Esokuqala yizindleko zezinto zokusetshenziswa eziqondile: okokufaka okuyinhloko kwe-FR-4 yi-copper foil, i-epoxy resin, kanye nendwangu yengilazi, kanye nokucindezela kwentengo yesaha ezintathu ngo-2025-2026. Isizathu sesibili, futhi okungenzeka ukuthi sikhulu, asiqondile - ukusabalala kokwabiwa okuvela ekushodeni kwe-laminate ephezulu. Njengoba abenzi be-CCL nabakhiqizi beshintsha umthamo wabo ongcono kakhulu baye ezintweni zeseva ye-AI ephezulu, umthamo washiya amamaki ajwayelekile wancipha, futhi abahlinzeki baqala ukubeka phambili amakhasimende abo anenani eliphezulu. Umphumela uba ukuthi i-FR-4 yaqina futhi yakhuphuka ngentengo yize ikhemistri yayo ingekho enkingeni.

Izinombolo zibonisa lokhu kuguquguquka kwemizila emibili. Amabanga e-laminate aphezulu akhuphuke ngo-20-40% phakathi naleso sikhathi, kuyilapho ukwanda okujwayelekile kwe-FR-4 kuvinjelwe kakhulu cishe ngo-10-15%, okubangelwa kakhulu ukushintsha kwe-foil yethusi kanye nokushintsha kokwabiwa kwe-fiber yengilazi kunokuba kube ukushoda kwezinto zokusetshenziswa ze-FR-4 zangempela. Umongo obanzi - ukuthi ukushoda kwezinto zokusetshenziswa kwe-PCB kugeleza kanjani emabhodini ajwayelekile - uhlanganiswe ku- PCB impahla yokuntuleka.

Abashayeli Bezinto Ezingavuthiwe Ababangela Izindleko ze-PCB

Izinto ezintathu zokusetshenziswa zisekela iningi lokwenyuka kwezindleko ze-FR-4. Ithusi liyimbangela enkulu kunazo zonke: i-copper foil imelela ingxenye enkulu yezindleko ze-laminate (kufika cishe engxenyeni yezindleko zezinto ze-CCL kwezinye izihlaziyi), kanye nethusi elithengiswa ngamazinga aqopha umlando - ngaphezu kuka-$13,000 ngethani ekuqaleni kuka-2026 - okunyusa izindleko ze-copper foil ngo-30% noma ngaphezulu. Ngenxa yokuthi ithusi liyadingeka nasezimotweni zikagesi kanye nengqalasizinda yamandla avuselelekayo, umncintiswano walo ubanzi futhi uyaphikelela.

Indwangu yefayibha yengilazi iyisishayeli sesibili. Ngisho nendwangu yengilazi ejwayelekile eqiniswe njengomthamo weglasi osezingeni eliphezulu yabhukwa kusengaphambili ngamakhasimende ehadiwe le-AI, futhi ukuchitheka kwehle ukutholakala futhi kwakhuphula amanani entengo yamamaki ajwayelekile. Ukuhlaziywa okuzinikele kusesiqondisweni sethu sokuntuleka kwendwangu yefayibha yengilazi . Umshayeli wesithathu yi-epoxy kanye ne-resin ekhethekile: kuyilapho i-epoxy ejwayelekile ingenamingcele kangako kunezinhlelo ze-PPO/PPE ezisetshenziswa kuma-laminate aphansi, izikhathi zokuhola ze-resin kanye namanani anyuswe kuwo wonke amabhodi. Isithombe esiqondile sethusi sichazwe kabanzi esihlokweni sethu sokuntuleka kwe-copper foil , kanti umbono ogcwele we-bill-of-materials usesiqondisweni sezindleko zokukhiqiza ze-PCB sika-2026.

Izinqumo Zokuklama Ezikhulisa Izindleko Zebhodi

Ingxenye enkulu yezindleko zebhodi inqunywa ngesikhathi sokuklama — kufika ku-80% wezindleko zokukhiqiza eziphelele ngaphambi kokuba amafayela eGerber akhishwe. Izinqumo eziningana ezivamile zokuklama zikhulisa izindleko zebhodi le-FR-4 ngokungadingekile emakethe yamanje:
