Isiseko sensimbi Copper Clock kunye ne-FR-4 ziibhodi ezimbini ezisetyenziswayo eziprintwayo (i-PCB) iprinta (i-PCB) kumashishini e-elektroniki. Bahluke kubume bezinto eziphathekayo, iimpawu zentsebenzo kunye neendawo zesicelo. Namhlanje, isiyensi ngokukhawuleza kuya kukubonelela ngohlalutyo lokuthelekisa kwezi zinto zimbini ezivela kwimbono yobungcali:
Isiseko sensimbi Copper Clock: Yinto esekwe kwi-PCB esekwe ngesinyithi, ihlala isebenzisa i-aluminium okanye yobhedu njengendawo ekhulileyo. Eyona nto iphambili kuyo kukuhamba kakuhle kwengqungquthela kunye nobushushu obunobushushu, ke oko kukhanya kakhulu kwizicelo ezifuna ukuqhubela phambili kwe-thermas ephezulu, njengokuguqulwa okunjalo kunye nokuguqulwa kwamandla. Isinyithi sesinyithi sinokuqhuba kakuhle ubushushu obuvela kumabala ashushu ePCB kuyo yonke iBhodi, ngaloo ndlela kunciphisa ukwakha kobushushu kunye nokuphucula ukusebenza kwesixhobo.
Fr-4: Fr-4 i-lamisa i-lamisa ilaphu ye-fiber njengezinto zokuqinisekisa kwaye i-epoxy iphinde iphinde ibe ngumthi. Okwangoku yeyona isetyenziswayo isetyenziswayo i-PCB, ngenxa yamandla akhe amahle, iipropathi zombane kunye neepropathi ezihlawulelweyo zedangatye kwaye zisetyenziswa ngokubanzi kwiimveliso ezahlukeneyo ze-elektroniki. Fr-4 inomgangatho wokuhlawula ilangatye kwi-UL94 v-0, oko kuthetha ukuba ivutha ilangatye ixesha elifutshane kakhulu kwaye lilungele ukusetyenziswa kwezixhobo zoKhuseleko.
Umahluko ophambili:
Izinto zentsimbi: Iipaneli zensimbi zensimbi
Ukuqhutywa kwe-thermal: Ukuqhubela kwe-thermal yephepha le-Clad liphezulu kakhulu kuno-Fr-4, olufanelekile kwizicelo ezifuna ukwamkelwa ngobushushu.
Ubunzima kunye nobunzima: Amaphepha e-Clad Sheet oqhelekileyo aqhelekileyo kunoFr-4 kwaye anokuba mncinci.
I-DR-4 Fr-4 kulula ukuyicwangcisa, ilungele uyilo oluninzi lwe-PCB; Ipleyiti yensimbi yobhedu kunzima ukuyiqhubela phambili, kodwa ilungele ukungakhethi lube yiyodwa okanye uyilo olunamagama amaninzi.
Ixabiso: Ixabiso lephepha lensimbi le-Cladper lihlala liphezulu kune-FR-4 ngenxa yexabiso eliphezulu lentsimbi.
Izicelo: Intsimbi ye-Cladper Copper isetyenziswa ikakhulu kwizixhobo ze-elektroniki ezifuna ukuchithwa kobushushu obufanelekileyo, njengamandla ekhompyutha kunye nokukhanyiswa kwamandla. I-Fr-4 ye-CR-4 iguquguqukayo, ifanelekile kwizixhobo ze-elektroniki ezisemgangathweni kunye nemizobo yePCB yePCB.
Ngokubanzi, ukhetho lwentsimbi yentsimbi okanye i-fr-4 ikakhulu ixhomekeke kwiimfuno zolawulo lwe-Thermal yemveliso, yiyilo lobunzima, uhlahlo-lwabiwo mali lweendleko.
