Inqubo yokukhiqiza ye-copper clad laminate (CCL) iwukugxilisa into eqinisayo nge-organic resin bese uyomisa ukwenza i-prepreg.A blank eyenziwe prepregs eziningana laminated ndawonye, eyodwa noma zombili izinhlangothi embozwe ucwecwe yethusi, futhi impahla emise okwepuleti okwakhiwa ngokucindezela hot.
Ngokombono wezindleko, ama-laminates e-copper clad enza cishe u-30% wawo wonke ukukhiqizwa kwe-PCB.Izinto zokusetshenziswa eziyinhloko zama-laminates ane-copper clad yindwangu yengilazi ye-fiber, i-wood pulp paper, i-copper foil, i-epoxy resin nezinye izinto.Phakathi kwazo, i-copper foil iyona nto eyinhloko yokukhiqiza ama-laminates e-copper clad., u-80% wengxenye yezinto ezibonakalayo uhlanganisa u-30% (ipuleti elincanyana) no-50% (ipuleti eliwugqinsi).
Umehluko ekusebenzeni kwezinhlobo ezihlukahlukene zama-laminates e-copper clad ubonakala ngokuyinhloko ekuhlukeni kwezinto eziqinisiwe ze-fiber kanye nama-resin azisebenzisayo.Izinto zokusetshenziswa eziyinhloko ezidingekayo ukukhiqiza i-PCB zihlanganisa i-copper clad laminate, i-prepreg, i-copper foil, i-gold potassium cyanide, amabhola ethusi noyinki, njll. I-Copper clad laminate iyona nto ebaluleke kakhulu eluhlaza.
Imboni ye-PCB ikhula kancane kancane
Ukusetshenziswa okwandile kwama-PCB kuzosekela kakhulu isidingo sesikhathi esizayo sezintambo zikagesi.Inani eliphumayo le-PCB lomhlaba wonke ngo-2019 licishe libe ngamaRandi ayizigidi eziyizinkulungwane ezingama-65, kanti imakethe ye-PCB yaseChina izinzile.Ngo-2019, inani lokukhishwa kwemakethe ye-PCB yaseChina licishe libe ngamaRandi ayizigidi eziyizinkulungwane ezingama-35.I-China iyisifunda esikhula ngokushesha kakhulu emhlabeni, esibalwa ngaphezu kwengxenye yenani lokuphumayo emhlabeni, futhi isazoqhubeka nokukhula esikhathini esizayo .
Ukusatshalaliswa kwesifunda kwevelu yokukhiphayo ye-PCB yomhlaba wonke.Ingxenye yenani lokukhiphayo le-PCB emazweni aseMelika, eYurophu, naseJapane emhlabeni liye lehla, kuyilapho inani lokuphumayo lemboni ye-PCB kwezinye izingxenye ze-Asia (ngaphandle kwaseJapane) liye lenyuka ngokushesha.Phakathi kwabo, ingxenye yezwe laseChina ikhule ngokushesha.Yimboni ye-PCB yomhlaba wonke.Isikhungo sokudlulisa.
