Inkqubo yokuvelisa i-copper clad laminate (CCL) kukufakela izinto eziqiniswayo kunye ne-organic resin kwaye uyomise ukwenza i-prepreg.I blank eyenziwe prepregs eziliqela elaminethiweyo kunye, elinye okanye macala omabini egqunywe ngefoyile yobhedu, kunye nepleyiti-shape impahla eyenziwe ngokucinezela hot.
Ukusuka kwindawo yeendleko zokujonga, i-laminates ye-copper clad i-akhawunti malunga ne-30% yemveliso yonke ye-PCB.Ezona zixhobo ziphambili zeelaminates ezigqunywe ngobhedu lilaphu lefiber yeglasi, iphepha lempuphu yeplanga, ifoyile yobhedu, i-epoxy resin kunye nezinye izinto.Phakathi kwazo, i-copper foil yeyona nto iphambili yokuvelisa i-laminates yobhedu., I-80% yecandelo lezinto eziphathekayo libandakanya i-30% (i-plate encinci) kunye ne-50% (i-plate plate).
Umahluko ekusebenzeni kweentlobo ezahlukeneyo ze-laminates ze-copper clad zibonakaliswa ngokukodwa kwiiyantlukwano kwizinto eziqiniswe kwifiber kunye nee-resin ezizisebenzisayo.Izinto eziphambili ezifunekayo ukuvelisa i-PCB ziquka i-copper clad laminate, i-prepreg, i-copper foil, i-cyanide yegolide ye-potassium, iibhola zobhedu kunye ne-inki, njl njl. I-Copper clad laminate yeyona nto ibalulekileyo ekrwada.
Ushishino lwePCB lukhula ngokuthe ngcembe
Ukusetyenziswa ngokubanzi kweePCBs kuya kuxhasa ngamandla imfuno yexesha elizayo yemisonto ye-elektroniki.Ixabiso lemveliso yePCB yehlabathi ngo-2019 limalunga neebhiliyoni ezingama-65 zeedola zaseMelika, kwaye imakethi yePCB yaseTshayina izinzile.Ngo-2019, ixabiso lemarike yePCB yaseTshayina liphantse libe ziibhiliyoni ezingama-35 zeedola zaseMelika.I-China ngowona mmandla ukhula ngokukhawuleza emhlabeni, obala ngaphezu kwesiqingatha sexabiso lemveliso yehlabathi, kwaye iya kuqhubeka ikhula kwixesha elizayo.
Ukuhanjiswa kwengingqi yexabiso lemveliso yePCB yehlabathi.Umyinge wexabiso lemveliso yePCB kumazwe aseMelika, eYurophu, naseJapan kwihlabathi liye lehla, ngelixa ixabiso lemveliso yePCB kwezinye iindawo zaseAsia (ngaphandle kweJapan) liye landa ngokukhawuleza.Phakathi kwabo, umlinganiselo welizwe laseTshayina unyuke ngokukhawuleza.Lishishini lehlabathi le-PCB.Iziko lodluliselo.
