Umthelela Wokuntuleka Kwe-Copper Foil Ekukhiqizweni Kwe-PCB

I-foil yethusi iyingqimba eqhubayo yawo wonke amabhodi esifunda aphrintiwe, futhi ngo-2026 ibe ngenye yezinto ezinzima kakhulu ku-PCB supply chain ukuyivikela ezingeni elifanele nangeshejuli esebenzayo. I-foil ngokwayo iyingxenyana encane yebhodi eliqediwe ngesisindo, kodwa intengo yayo kanye nokutholakala kwayo manje kushintsha yonke izindleko ze-laminate embozwe ngethusi, futhi iphrofayili ye-foil eyodwa evinjelwe ingavimba i-oda lokukhiqiza elilungele. Lo mhlahlandlela uchaza ukuthi kungani i-foil yethusi ibalulekile, ukuthi ukushoda kwayo kushintsha kanjani intengo ye-PCB, umehluko phakathi kwamabanga ajwayelekile kanye nama-HVLP, nokuthi abathengi bangenzani ukuvikela izinhlelo zabo.

Kungani I-Copper Foil Ibaluleke Kakhulu Ekukhiqizweni Kwe-PCB

Wonke umqhubi we-PCB — yonke i-trace, i-plane, kanye ne-pad — uqala njenge-foil yethusi eboshelwe enkabeni ye-laminate. I-foil ayishintshisani kuyo yonke imiklamo: ukujiya kwayo, ubulukhuni bomphezulu, kanye ne-chemistry yokwelapha kunquma ngqo ukuthi ibhodi lithwala kahle kangakanani izimpawu zamanje nezemvamisa ephezulu. Umenzi akanakumane afake i-foil eyodwa esikhundleni senye ngaphandle kokuthinta i-impedance, ukunamathela, kanye nokulahleka kwesignali, yingakho ibanga le-foil elivinjelwe liziphatha njengomklamo ovinjelwe kunokuba kube yigebe lempahla ejwayelekile.

I-foil yethusi nayo itholakala phansi kwenqwaba yezinto zokwakha. Iwukufakwa okukhulu kakhulu kwe-laminate embozwe ngethusi, okwenza cishe u-40% (cishe u-42% ngokuhlukaniswa okuvamile kwemboni) kwezindleko zezinto zokwakha ze-CCL, ngaphambi kwe-resin cishe ikota kanye nendwangu yengilazi cishe ikota. Ngenxa yokuthi i-CCL nayo ibala u-30-40% wezindleko eziphelele zebhodi elinezingqimba eziningi, intengo ye-foil yethusi ikhuphuka izendlalelo ezimbili zeketanga lokuhlinzeka ngaphambi kokuba ifike kumthengi. Lapho i-foil iqina, abenzi be-laminate abakwazi ukwakha i-CCL, abenzi be-laminate abakwazi ukwakha amabhodi, futhi umkhawulo ubonakala njengamanani aphezulu kanye nemigqa emide. Lokhu kuxhumana kuyisisekelo sokubuka konke kwethu kokuntuleka kwezinto ze-PCB kanye nokuhlaziywa kokuntuleka kwe-CCL okuzinikele.

Indlela Ukushoda Kwe-Copper Foil Okuthinta Ngayo Amanani E-PCB
