4 Ungqimba ENIG FR4 I-Heavy Copper PCB
I-Heavy Copper PCB
Amabhodi e-PCB ethusi esindayo angenziwa kalula ngenhlanganisela yezinqubo ezimbili eziyinhloko, i-electroplating ne-etching.Ngokungafani namanye ama-PCBS, isifunda senziwe ngendwangu encane ye-foil yethusi.
Ama-PCB ethusi esindayo ahlanganiswe ngokulinganayo nge-FR4 noma enye impahla esekwe epoxy.Isilinganiso sesisindo sama-PCB ethusi esindayo singaba ama-ounces angu-4 (140μm), okuyisilinganiso esingcono kunenye i-PCB yethusi evamile.
Ugqinsi lwethusi obengeziwe luvumela ibhodi ukuthi liqhube imisinga ephakeme, lifinyelele ukusatshalaliswa kokushisa okuhle, futhi linike amandla ukushintsha okuyinkimbinkimbi endaweni elinganiselwe.Ezinye izinzuzo zihlanganisa amandla angeziwe emishini ezindaweni zokuxhuma, ikhono lokudala osayizi bemikhiqizo abancane ngokuhlanganisa izisindo eziningi kungqimba olufanayo lwesekethe, kanye nekhono lokusebenzisa izinto ezikhethekile ezinengcuphe encane yokuhluleka kwesekethe.
Izinzuzo Ze-Heavy Copper PCB
Ukwakhiwa kwama-PCB ethusi esindayo kuhilela ukusetshenziswa kwe-plating noma ukunamathisela, njengoba kwandisa ukushuba kwe-PCB yethusi ezindongeni eziseceleni nezimbobo zokunamathisela.Ngaphezu kwalokho, i-PCBS yethusi esindayo i-electroplated ngesikhathi sokukhiqizwa kwe-PCB.Lokhu kusiza ukujiya udonga lwe-PTH ku-PCB.Ezinye izici ze-PCBS zethusi eziwugqinsi ezihlukile kwezinye i-PCBS zifaka:
Isisindo sethusi:
Lokhu kuyisici esiyinhloko se-PCB yethusi esindayo.Isho isisindo sethusi esisetshenziswa ngonyawo lwesikwele ngama-ounces.
Ikhava
Ucwecwe lwethusi lwangaphandle.Isisindo sethusi sesendlalelo sangaphandle siwumklamo ojwayelekile obekwe kusengaphambili.
Isendlalelo Sangaphakathi
Ikhwalithi yethusi nokuqina kwe-dielectric kwesendlalelo sangaphakathi yizinto ezichazwe ngaphambilini ezijwayelekile.Kodwa-ke, zingashintshwa ukuze zihambisane nezidingo ezenziwe ngokwezifiso zephrojekthi.
Isicelo Of Heavy Copper PCB
Ama-PCB ethusi esindayo asetshenziswa ezinhlelweni ezihlukahlukene, njengeziguquli eziyisicaba, ukusakazeka kokushisa, ukuhlakazeka kwamandla aphezulu, iziguquli zokulawula, njll. Ku-PC, ukulawulwa kwezimoto, ezempi kanye nokwemishini, isithakazelo samapuleti acwecwe ngethusi ayakhula.Amabhodi esekethe aphrintiwe ethusi esindayo nawo asetshenziswa kabanzi:
1. Ukunikezwa kwamandla nokulawula isiguquli
2. Igunya lokwabiwa kwezimali
3. Amathuluzi okushisela noma izinto zokusebenza
4. Imboni yezimoto
5. Abakhiqizi bephaneli yelanga, njll
