I-Metal base copper clad plate kanye ne-FR-4 yizingxenye ezimbili zebhodi lesifunda eliphrintiwe (PCB) elivame ukusetshenziswa embonini ye-electronics. Zihlukene ngokwakhiwa kwezinto, izici zokusebenza kanye nezinkambu zohlelo lokusebenza. Namuhla, i-Fastline izokunikeza ukuhlaziywa okuqhathanisayo kwalezi zinto ezimbili ngokubuka kochwepheshe:

I-Metal base Copper clad plate: Yimpahla ye-PCB esekwe ngensimbi, ngokuvamile isebenzisa i-aluminium noma ithusi njenge-substrate. Isici saso esiyinhloko yi-conductivity enhle ye-thermal kanye nekhono lokukhipha ukushisa, ngakho-ke idume kakhulu ezinhlelweni ezidinga ukuqhutshwa kokushisa okuphezulu, njengokukhanyisa kwe-LED neziguquli zamandla. I-substrate yensimbi ingakwazi ukuphatha kahle ukushisa kusuka ezindaweni ezishisayo ze-PCB kuya kulo lonke ibhodi, ngaleyo ndlela yehlise ukwakheka kokushisa futhi ithuthukise ukusebenza okuphelele kwedivayisi.

I-FR-4: I-FR-4 iyimpahla ye-laminate enendwangu ye-fiber yengilazi njengento eqinisayo kanye ne-epoxy resin njengesibophezelo. Njengamanje iyi-substrate ye-PCB esetshenziswa kakhulu, ngenxa yamandla ayo okusebenza kahle, izakhiwo zokuvala ugesi kanye nezindawo ezibushela ilangabi futhi isetshenziswa kakhulu emikhiqizweni eyahlukene kagesi. I-FR-4 inesilinganiso se-flame retardant se-UL94 V-0, okusho ukuthi ivutha elangabini isikhathi esifushane kakhulu futhi ifanele ukusetshenziswa kumadivayisi kagesi anezidingo eziphezulu zokuphepha.

umehluko omkhulu:

Okubalulekile kwe-Substrate: Amaphaneli ensimbi agqoke ithusi asebenzisa insimbi (efana ne-aluminium noma ithusi) njenge-substrate, kuyilapho i-FR-4 isebenzisa indwangu ye-fiberglass ne-epoxy resin.

I-Thermal conductivity: I-thermal conductivity yeshidi le-metal clad iphakeme kakhulu kunaleyo ye-FR-4, elungele izinhlelo zokusebenza ezidinga ukuchithwa kahle kokushisa.

Isisindo nokuqina: Amashidi ethusi agqoke insimbi ngokuvamile asindayo kuno-FR-4 futhi angase abe mancane.

Ikhono lenqubo: I-FR-4 kulula ukuyicubungula, ilungele ukwakheka kwe-PCB enezingqimba eziningi; Ipuleti le-metal eligqoke ithusi linzima ukulicubungula, kodwa lilungele ungqimba olulodwa noma umklamo olula we-multi-layer.

Izindleko: Izindleko zeshidi lethusi eligqoke insimbi ngokuvamile ziba phezulu kuno-FR-4 ngenxa yenani lensimbi eliphakeme.

Izicelo: Amapuleti ethusi agqoke insimbi asetshenziswa kakhulu kumishini kagesi edinga ukuchithwa kahle kokushisa, njengama-electronics amandla kanye nezibani ze-LED. I-FR-4 iguquguquka kakhulu, ifaneleka kakhulu kumadivayisi kagesi ajwayelekile kanye nemiklamo ye-PCB enezingqimba eziningi.

Ngokuvamile, ukukhethwa kwe-metal clad noma i-FR-4 ikakhulukazi kuncike ezidingweni zokuphatha ezishisayo zomkhiqizo, ubunzima bokuklama, isabelomali sezindleko kanye nezidingo zokuphepha.
