I-substrate yethusi yokupholisa i-LED
Ngokuthuthuka okusheshayo kokukhanyisa kwe-LED namuhla, ukuchithwa kokushisa kuyinkinga eyinhloko yokukhanyisa kwe-LED.Singayixazulula kanjani inkinga yokukhishwa kokushisa kwe-LED?Namuhla sizokhuluma ngenkinga ye-LED ye-heat dissipation yethusi substrate ye-LED yokushisa ukushisa.Imboni ye-LED ingenye yezimboni...Funda kabanzi -
Yiziphi izindawo zokulawula zenqubo yokukhiqiza eyinhloko yamabhodi esekethe anezendlalelo eziningi
Amabhodi wesekethe we-multilayer ngokuvamile achazwa njengamabhodi wesekethe angu-10-20 noma ngaphezulu wezinga eliphezulu lezendlalelo eziningi, okunzima kakhulu ukuwacubungula kunamabhodi esekethe esekayizi eziningi futhi adinga izinga eliphezulu nokuqina.Isetshenziswa kakhulu emishinini yokuxhumana, amaseva aphezulu, i-electron yezokwelapha...Funda kabanzi -
Isimiso sezintambo sebhodi le-PCB elendlalelo ezimbili
I-PCB iyingxenye ebalulekile ye-elekthronikhi kanye nomsuka wazo zonke izingxenye ze-elekthronikhi.Selokhu yavela emhlabeni wokugcina.Ukusuka kungqimba olulodwa kuya kungqimba oluphindwe kabili, ungqimba olune, bese kuya ku-multi-layer, nobunzima bokuklama nabo buyanda.enkulu.Kukhona izintambo...Funda kabanzi -
Ukuhlaziywa kwamathiphu okuhlanza amabhodi wesifunda we-PCB
Amabhodi esekethe e-PCB asetshenziswa kakhulu e-China, futhi ukungcola kuzokwenziwa ngesikhathi sokukhiqiza amabhodi esekethe aphrintiwe, okuhlanganisa uthuli nemfucumfucu enqubweni yokukhiqiza njengezinsalela zokuguquguquka nokunamathiswa.Uma ibhodi le-pcb lingakwazi ukuqinisekisa kahle indawo ehlanzekile, ...Funda kabanzi -
I-chip idayiswa kanjani ebhodini lesifunda?
I-chip yilokho esikubiza ngokuthi i-IC, eyakhiwe umthombo wekristalu nokupakishwa kwangaphandle, kuncane njenge-transistor, futhi i-CPU yekhompyutha yethu yilokho esikubiza ngokuthi i-IC.Ngokuvamile, ifakwa ku-PCB ngokusebenzisa izikhonkwane (okungukuthi, Ibhodi lesifunda olishilo), elihlukaniswe ngamaphakheji evolumu ahlukene...Funda kabanzi -
I-PCB THERMAL DESIGN HACK IYASHISA FUTHI ISINDE
Ngenxa yokukhuphuka kwakamuva kwezinsizakalo zokukhiqiza zebhodi lesifunda ezithengekayo, abantu abaningi abafunda i-Hackaday manje bafunda ubuciko bomklamo we-PCB.Kulabo kini abasakhiqiza "Sawubona Umhlaba" okulingana no-FR4, yonke imikhondo ifika lapho kufanele ibe khona, futhi ...Funda kabanzi
