Ukuntuleka Kwezinto Ze-PCB Umthelela Ezindleko Nesikhathi Sokuhola

Eminyakeni eminingi engamashumi amabili edlule, i-laminate ngaphakathi kwebhodi lesifunda eliphrintiwe yayiyingxenye yezinto umthengi ayengakhathazeki kakhulu ngazo. Yayiningi, ishibhile uma kuqhathaniswa nokuhlanganiswa nezingxenye, futhi akuvamile ukuba yinto eyayinquma ukuthi ibhodi lithunyelwe ngesikhathi. Lokho kucabanga akusasebenzi. Kusukela ngo-2024, izinto ezifakwa kwi-PCB — i-laminate embozwe ngethusi (CCL), i-foil yethusi, indwangu yefayibha yengilazi, kanye nezinhlelo ze-resin ezizibophayo — ziye zangena ekushodeni kwesakhiwo, okubangelwa ukwanda okungakaze kubonwe kwesidingo esivela kwihadiwe yeseva ye-AI. Ekuqaleni kuka-2026 umkhawulo wawusakazeke kusukela emazingeni aphezulu angaphandle wehla waya ku-FR-4 evamile, kushintsha izindleko, isikhathi sokuhola, kanye nokutholakala kwezinto cishe kuzo zonke izinhlelo ze-PCB. Lo mhlahlandlela uchaza okwenzekayo, ukuthi yiziphi izinto ezithinteka kakhulu, ukuthi ukushoda kugeleza kanjani kuze kufike entengo yakho ecashuniwe kanye nosuku lokulethwa, nokuthi umenzi kanye nomthengi we-OEM bangenzani ngakho.

Kungani Ukushoda Kwezinto Eziphathekayo ze-PCB Kuqhubeka Kuthinta Ukukhiqizwa Kwezinto Zogesi

Imbangela eyinhloko ukufunwa, hhayi ingozi eyodwa yokuphakelwa. I-AI server PCB isebenzisa i-laminate eningi kakhulu ngeyunithi kunebhodi leseva elivamile, futhi amabhodi ngokwawo akhule kakhulu. Inani elimaphakathi lezendlalelo ze-AI server PCB lenyuke lisuka cishe ezingqimbeni eziyi-18 ngo-2023 laya cishe ezingqimbeni ezingama-32 ngo-2025, futhi iseva ye-AI ephezulu idinga i-CCL ephindwe kaningana ngevolumu kuneseva yendabuko. Phindaphinda lokho kusetshenziswa kweyunithi ngayinye ngokukhula kokuthunyelwa kweseva ye-AI okusebenza kahle ngaphezu kwama-25% ngonyaka, futhi umphumela uwushintsho oluncane ekudingweni kwezinto ezibonakalayo imboni ye-CCL engakaze yakhelwe ukumunca kulo mugqa wesikhathi.

Okwenza isimo siqhubeke kunokuba sibe sesikhashana ukuthi ukushoda kuse-"phezulu komfula." I-CCL akuyona impahla; iyinhlanganisela enembile ye-foil yethusi enamathiselwe kwi-substrate ye-resin eqiniswe nge-fiber yengilazi. Okuthathu kwalokho okufakwayo kwayo - i-foil yethusi, indwangu yengilazi ye-elekthronikhi, kanye ne-resin ekhethekile - kuqiniswe ngesikhathi esifanayo. Amanani e-foil yethusi akhuphuke kanye nethusi uqobo, elahweba ngaphezu kuka-$13,000 ngethani ekuqaleni kuka-2026, kanti i-foil yethusi imelela cishe u-40% wezindleko zezinto zokusetshenziswa ze-CCL. Umthamo wendwangu yengilazi ephezulu (i-T-glass kanye ne-Q-glass) wawubhukwe kakhulu ngamakhasimende ehadiwe le-AI. Futhi ukuphazamiseka kokunikezwa kwe-resin ye-PPE/PPO kususe umgogodla we-resin obalulekile osetshenziswa ezinhlelweni ze-laminate zokulahlekelwa okuphakathi kanye nokulahlekelwa okuphansi. Lapho indlela ecacile yokuxazulula inkinga eyodwa ivinjelwa enye, imingcele iyahlangana.

Indlela yesibili igcina ingcindezi igeleza emabhodini ajwayelekile: ukucindezela komthamo. Njengoba abenzi be-CCL kanye nabakhiqizi bebeka imigqa yabo yokukhiqiza engcono kakhulu ezintweni zeseva ye-AI ephezulu, umthamo we-laminate yezimoto, yezimboni, kanye neyezinga labathengi uyancipha. Umphumela uba ukuthi ngisho ne-FR-4 ejwayelekile - esebenzisa i-chemistry ehlukile futhi engekho enkingeni yangempela yezinto zokusetshenziswa - ibone izikhathi zokuhola zikhula futhi amanani enyuka ngoba abahlinzeki babeka phambili amakhasimende abo anenani eliphezulu kuqala. Yingakho umthengi o-oda ibhodi elula enezingqimba ezine engenasidingo esingavamile angamangala ngesilinganiso eseluliwe ngo-2026.

Yikuphi Izinto ze-PCB Ezinezikhathi Ezinde Kakhulu Zokuhola

Isikhathi sokulethwa kwezinto ezibonakalayo ngo-2026 siqondwa kangcono njengesikhathi esidingekayo ukuze kuqinisekiswe ukwabiwa ohlelweni lwe-quota kunesilinganiso sokuthi umenzi umatasa kangakanani. Ukwenziwa kwebhodi elilawulwayo eliyi-impedance manje kuqala kuphela ngemva kokuba ibanga elifanele le-CCL linikezwe i-oda, futhi lelo banga ngokwalo linikezwa kuphela ngemva kokuba i-resin, i-foil yethusi, kanye nendwangu yengilazi edingekayo ukuze kwakhiwe kuqinisekisiwe. Isithombe sesikhathi sokulethwa, esi-odwe kusukela kokuncane kuya kokuncane kakhulu, sibukeka kanje ngo-2026:

• I-FR-4 ejwayelekile: isuke emavikini angu-2-3 omlando yaya emavikini angaba ngu-6-8, iqhutshwa ukushintshana kwe-foil yethusi kanye nendwangu yengilazi esikhundleni sokuntuleka kwezinto zokusetshenziswa ze-FR-4 zangempela.
• I-High-Tg FR-4: iqine kakhulu kune-FR-4 ejwayelekile, kanti amamaki aphakathi kwe-Tg kanye namamaki aphezulu e-Tg ngezinye izikhathi athwala isikhathi eside ngamabomu njengoba ama-laminator evimbela ukuthengwa kobuchwepheshe obuphakathi.
• Ama-laminate aphansi okulahlekelwa yi-M6 / M7 (asekelwe ku-PPO/PPE): isuke emavikini angaba ngu-4-6 yaya emavikini angu-14-18, kanti amanye amamaki aphezulu abikwe ukuthi afinyelela ezinsukwini ezingu-140.
• Amabanga engilazi ye-M8 / M9 Q: isabelo kuphela, ngokuvamile amasonto angama-20+, kanti amanye amamaki e-CCL abekwe ohlelweni lwesilinganiso sezinyanga eziyisithupha.
• Okufakwayo okukhethekile: I-foil yethusi ye-HVLP (i-foil ephansi kakhulu edingekayo ukuze kutholakale isignali yezinga eliphezulu) kanye nendwangu yengilazi ye-quartz ehlanzekile kakhulu ziphakathi kwezinto ezivinjelwe kakhulu, kanye nokubikezelwa kwemboni kokushoda kwamathani ayizinkulungwane eziningi ku-foil ye-HVLP kuze kube ngu-2026 no-2027.

Umphumela ongokoqobo ukuthi i-laminate, hhayi umugqa wokukhiqiza, manje ilawula ishejuli yanoma yiliphi ibhodi elichaza izinto zokulahlekelwa okuphakathi noma zokulahlekelwa okuphansi. Isikhathi sokuhola se-CCL sezinyanga eziyisithupha sisho ukuthi i-oda lokukhiqiza elibekwe namuhla lebhodi elithuthukisiwe le-laminate lingase lingatholi i-substrate isigamu sonyaka - isikhathi esingasebenzi ukuhlela okuningi kokukhiqiza okujwayelekile. Ukuhlaziywa kwethu okuningiliziwe kwesimo sokuhlinzekwa kusekuhlaziyweni kokuntuleka kwezinto ze-PCB , futhi ukubuka okufanayo kokuthi lokhu kuthinta kanjani ishejuli kusesiqondisweni esinikezelwe ngesikhathi sokuhola se-PCB.

Indlela Ukutholakala Kwezinto Ezibalulekile Okushintsha Ngayo Amanani E-PCB

Ukutholakala kwezinto ezibonakalayo kanye nentengo ye-PCB manje sekuhlanganiswe ngokuqinile ngendlela okwakungeyona eminyakeni emithathu edlule. Ku-PCB yeseva ejwayelekile enezingqimba eziningi, i-CCL ingabala u-30–40% wezindleko eziphelele, ngakho-ke lapho amanani e-CCL ekhuphuka, amanani ebhodi alandela eduze. Amanani okungenisa e-CCL aseNingizimu Korea afinyelele ezingeni elingakaze libonwe ngaphambili ngaphezu kuka-$20,000 ngethani ngoMashi 2026 - ukwanda okungu-74.5% unyaka nonyaka futhi okokuqala lowo mkhawulo weqiwe selokhu amarekhodi aqala ngo-2000. Ama-laminator ahamba phambili akhiphe izaziso eziphindaphindwayo zokwenyuka kwentengo ngasekupheleni kuka-2025 kuya ku-2026, ngamamaki aphezulu enyuka ngo-20–40% kanye ne-FR-4 ejwayelekile ekhuphuka ngo-10–15%.

Isizathu sokuthi ijika lezindleko liphezulu kangaka kumabhodi athuthukile yileli lebanga le-CCL. Ukukhuphuka ibanga - kusuka ku-FR-4 kuya ku-M4, M6, M7, M8, M9 - akugcini nje ngokungeza izindleko; kushintsha i-resin chemistry, iphrofayili ye-copper-foil, kanye nebanga lendwangu yengilazi konke ngesikhathi esisodwa, kuphindaphinde izindleko zezinto esikhundleni sokulikhulisa. Izibalo zemboni zibeka i-M6 cishe ku-3–5× standard FR-4, M7 ku-6–9×, M8 ku-10–15×, kanye ne-M9 Q-glass ku-15–20×. Umklamo ochaza ibanga le-premium lapho ibanga elijwayelekile lingahlangabezana nezinhloso zalo zikagesi ngakho-ke ukhokha inhlawulo engalingani emakethe yamanje. Izindleko ze-BOM ze-AI server PCBA kulinganiselwa ukuthi zikhuphuke ngo-25–40% uma kuqhathaniswa nemiklamo efanayo ye-H2-2025. Umnotho ogcwele uhlanganiswe kumhlahlandlela wethu wezindleko zokukhiqiza ze-PCB ka-2026 kanye nomongo wesu esiphephweni sezindleko ze-PCB sika-2026.

Izingozi Zokuhlinzekwa Kwabathengi Be-OEM

Kumthengi we-OEM, ingozi eyinhloko akuseyona nje intengo - ukuthi ibhodi lingase lingatholakali ngokwethembeka nganoma iyiphi intengo ngaphakathi kwefasitela lokuhlela. Izingozi eziningana ezithile zidinga ukunakwa:

• Ukufaneleka kwesilinganiso. Emakethe eguquguqukayo, intengo ecashunwe namuhla ingase ingasebenzi ngesikhathi i-PO ibekwa emavikini kamuva. Izivumelwano zonyaka zentengo engaguquki ziye zayeka kakhulu ukusinda ekuguquguqukeni; intengo enenkomba exhunywe ku-foil yethusi ecacile kanye nefomula yokulungiswa kwebanga le-CCL isiba yinto evamile.
• Ukuhlushwa kwezinto ezitholakala emthonjeni owodwa. Ibhodi elincike ku-laminate eyodwa ekhethekile, iphrofayili eyodwa ye-foil, kanye nebanga elilodwa lengilazi lithwala ingozi ehlanganisiwe kungakhathaliseki ukuthi bangaki abakhiqizi abangalicaphuna. Uma ibanga elilodwa elifanelekile lilahlekelwa isabelo, wonke abakhiqizi banamathela ngokulinganayo.
• Ukufuduka kwesabelo. Uma izinto zokwakha zintuleka, abahlinzeki babeka phambili ubudlelwano babo obunenzuzo kakhulu nobuhlala isikhathi eside. Umthengi ohambisa umsebenzi esitolo esishibhile kakhulu esitholakalayo angathola ukuthi isitolo sinesikhundla sokwabiwa esibuthakathaka kakhulu.
• Ukubikezela ubumpumputhe. Abakhiqizi bangakwazi ukuthola ukwabiwa kwezinto kuphela uma bebhekene nesidingo abasibonayo. Umthengi ongenayo i-foreward prediction akaniki lutho oluzohlelwa ngokumelene nochungechunge lokuhlinzeka.

Ukunciphisa okusebenza njalo ukwabelana ngesibikezelo sokukhiqiza sezinyanga eziyi-6-12 nomenzi ukuze izinto zabelwe ngokumelene naso, kufanelane nebanga lesibili elilinganayo le-CCL ngebhodi elibalulekile, kanye nokwamukela amanani anenkomba esikhundleni sezingcaphuno eziqinile. Lokhu kuyindlela yokuthenga, kodwa kuncike ezinqumweni zobunjiniyela ezenziwe ngesikhathi sokuklama.

Izinto Ezingakhethwa Abakhiqizi be-PCB

Impendulo ephumelela kakhulu ku-laminate evinjiwe akuvamile ukuthi “ilinde ukuthi uhlobo oluqanjwe ngalo lutholakale.” Iwukufanisa okulingana nalo. Ama-laminate amaningi e-premium anokulingana okukodwa noma ngaphezulu okusebenzayo okuhlangabezana nezinhloso ezifanayo ze-Dk/Df kanye ne-Tg kodwa ahlala emgqeni wokwabiwa komhlinzeki ohlukile. Ibhodi le-Panasonic Megtron 6, isibonelo, kufanele libe nezinto zesibili ezifanayo ezifanelekile — okulingana okuvamile kufaka phakathi i-TUC Tachyon-100G, i-EMC EM-528, kanye ne-Iteq IT-988GSE — ukuze inkinga yokwabiwa kwebanga elilodwa ingamisi uhlelo.

I-lever yesibili yi-hybrid stack-up: ukucacisa ibanga le-premium kuphela ezingqimbeni eziphethe izimpawu ezibalulekile zezinga eliphezulu kanye nokusebenzisa i-high-Tg FR-4 noma ibanga lokulahlekelwa okuphakathi ezingqimbeni ezisele. Lokhu kunciphisa ukusetshenziswa kwe-premium-CCL kakhulu ngenkathi kusahlangabezana nezinhloso zokulahlekelwa kanye ne-impedance, futhi kuguqula ukuthembela kwebhodi lonke ebangeni eliyivelakancane kube ukuthembela okulinganiselwe ezingqimbeni ezimbalwa. Ukuhlelwa kabusha kwe-hybrid okubhaliwe kunganciphisa ukusetshenziswa kwe-premium CCL cishe izingxenye ezimbili kwezintathu futhi kususe umjikelezo we-lamination, kunciphise izindleko zebhodi ngalinye ngendlela enenjongo ngaphandle kokuphazamiseka kukagesi. Indlela evamile ichazwe kumhlahlandlela wethu wokunciphisa izindleko ze-PCB ngo-2026 , futhi ukuhwebelana kwezinto eziyisisekelo kuhlanganiswe ekukhetheni izinto ze-PCB kanye nezinketho ezikhethekile ze-laminate eziphansi zokulahlekelwa okukhethekile.

Inketho yesithathu, lapho izidingo zikagesi zivuma, ukwehlisa ukucaciswa: ukuqinisekisa ukuthi impahla yezinga elijwayelekile ingahlangabezana yini nesidingo se-Dk/Df ngaphambi kokwehluleka ukwenza ukucaciswa kwe-premium, nokuthi i-140-Tg FR-4 yanele yini ngaphambi kokukhokhela i-170-Tg. Ukucaciswa ngokweqile manje sekubiza kakhulu kunango-2024 futhi kungenye yezindlela ezivame kakhulu zokugwema izindleko.

Indlela Ukuhlela Ukuhlelwa Kwangaphambi Kwesikhathi Okukunciphisa Ngayo Ukubambezeleka

Kufika ku-80% wezindleko zokukhiqiza zebhodi eziphelele zivaliwe ngesikhathi sesigaba sokuklama. Ngesikhathi amafayela e-Gerber ekhishwa, inani lezingqimba, ibanga le-CCL, isisindo sethusi, ngokwakhiwa kwezakhiwo, ifomethi yephaneli, kanye nokuphela kwendawo sekuvele kulungisiwe — futhi ngo-2026 lezo yizo kanye iziguquguquki ezinquma kokubili izindleko kanye nokutholakala. Ithimba lokuthenga alikwazi ukuxoxisana nge-laminate ye-premium kuze kufike ku-FR-4 ngemva kwalokho; isinqumo senziwe lapho kubekwa i-stack-up.

Ngakho-ke ukuhlela ukuhlanganiswa kokuqala kwenza izinto ezimbili ngesikhathi esisodwa. Okokuqala, kuvumela ukwakheka ukuthi kuchaze ibanga elincane elihlangabezana nomkhawulo wangempela wesendlalelo ngasinye kunokucacisa ngokweqile ibhodi lonke, okunciphisa ngqo ukuvezwa kwamamaki ezinto ezinqunyelwe kakhulu. Okwesibili, kuvumela ibanga lesibili elilinganayo ukuthi lifaneleke ngaphambi kokuba umklamo uqandwe, ngakho-ke uhlelo lune-fallback eyakhelwe ngaphakathi uma ibanga eliyinhloko lilahlekelwa isabelo. Ukuhlanganiswa okubukeziwe ngokutholakala kwezinto zamanje - kusetshenziswa amanani angempela e-laminate Dk kanye nokubalwa kwe-impedance okuqinisekisiwe - akunakwenzeka ukuthi kume ukulinda ibanga elilodwa eliyivelakancane. Ithimba lethu linikeza ukubalwa kokuhlanganiswa okuqinisekisiwe kwayo yonke idizayini yokulawulwa kwe-impedance ngokubuyekezwa kwangaphambi kokwenziwa; izisekelo zikumhlahlandlela wethu wokuhlanganiswa kwe-PCB kanye nomhlahlandlela wokuklama we-HDI stack-up.
