I-Metal Base Copper Clad Plate kanye ne-FR-4 iyibhodi yesifunda esetshenzisiwe esetshenzisiwe ephrintiwe (PCB) esetshenziswayo embonini yama-elekthronikhi. Ziyahlukahluka ngokwakheka kwezinto ezibonakalayo, izici zokusebenza kanye nezinkundla zohlelo lokusebenza. Namuhla, i-Fastline izokunikeza ukuhlaziya okuqhathanisayo kwalezi zinto ezimbili ngombono ochwepheshe:
I-Metal Base Copper Clad Plate: Yinto ye-PCB esekwe ngensimbi, imvamisa usebenzisa i-aluminium noma ithusi njenge-substrate. Isici salo esikhulu yinhle yokuvuselelwa okushisayo kanye nekhono lokuhlanza ukushisa, ngakho-ke kudume kakhulu kwizicelo ezidinga ukuvumelanisa okuphezulu, njengokukhanya kwe-LED kanye nabaguquli bamandla. I-substrate yensimbi ingahle ikwazi ukwenza kahle ukushisa okuvela ezindaweni ezishisayo ze-PCB kuyo yonke ibhodi, ngaleyo ndlela kunciphise ukwakha ukushisa nokwenza ngcono ukusebenza okuphelele kwensiza.
I-FR-4: I-FR-4 iyisitayela sama-liquate ngendwangu ye-fiber yengilazi njengendwangu eqinisayo ne-epoxy resin njenge-binder. Njengamanje iyona esetshenziselwa i-PCB esetshenziswa kakhulu, ngenxa yamandla ayo amahle emishini, izakhiwo zogesi zikagesi kanye nezindawo zokubuyisa amalangabi futhi zisetshenziswa kabanzi kwimikhiqizo ehlukahlukene ye-elekthronikhi. I-FR-4 inesilinganiso se-flame retardant ye-UL94 V-0, okusho ukuthi ishisa ilangabi isikhathi esifushane kakhulu futhi ilungele ukusetshenziswa kumadivayisi we-elekthronikhi anezidingo eziphezulu zokuphepha.
umehluko obalulekile:
Izinto ezisetshenziswayo ze-substrate: Amaphaneli wensimbi-clad asebenzisa insimbi (njenge-aluminium noma ithusi) njenge-substrate, kanti i-fr-4 isebenzisa indwangu ye-fiberglass ne-epoxy resin.
Ukuvuselelwa okushisayo: Ukuvuselelwa okushisayo kwephepha le-Metal Clad kuphakeme kakhulu kunalokho kwe-FR-4, okulungele izinhlelo zokusebenza ezidinga ukufethina okuhle kokushisa.
Isisindo nobukhulu: Amashidi we-Metal Clad Copper ajwayelekile kune-FR-4 futhi angaba mncane.
Ikhono lenqubo: I-FR-4 kulula ukuyicubungula, ilungele ukwakheka okuyinkimbinkimbi kwe-PCB ye-PCB; I-Metal Clad Comper Plate kunzima ukuyicubungula, kepha ilungele ungqimba olulodwa noma umklamo olula welendlalelo.
Izindleko: Izindleko zeshidi lethusi lensimbi Clad livame ukuphakeme kune-FR-4 ngenxa yentengo yensimbi ephakeme.
Izicelo: Amapuleti wensimbi Clad Copper asetshenziswa ikakhulukazi kumadivaysi e-elekthronikhi adinga ukuhlukaniswa okuhle kokushisa, njenge-Power Electronics nokukhanyisa kwe-LED. I-FR-4 iguquguqukayo ngokwengeziwe, ilungele amadivaysi ajwayelekile kagesi kanye nemiklamo ye-PCB ehlukahlukene.
Ngokuvamile, ukukhetha kwe-metal clad noma i-fr-4 ikakhulukazi kuya ngezidingo zokuphathwa kwe-thermal zomkhiqizo, ukuklama kwesabelomali, isabelomali sezindleko kanye nezidingo zokuphepha.
