EMI uye EMC Basics
Chii chinonzi EMI?
Iwe unonzwa nezve emi kana uchishanda nemagetsi. EMI zvinoreva kukanganiswa kwemagetsi. Zvinoitika kana masaini akanganisa mashandiro anoita zvishandiso. Zviratidzo izvi zvinogona kubva simba mitsetse, injini, kana mamwe masekete pamusoro pcb yako marongerwo. Unogona kunzwa emi seruzha muvatauri kana kuona glitches mumagetsi edhijitari. Kana iwe ukaregeredza emi, dunhu rako rinogona kusashanda nemazvo. Iwe unogona kuderedza emi nekushandisa matanho akanaka ekugadzira uye nhovo.
Zano: Gara uchitsvaga emi masosi munzvimbo yako yebasa. Kufambisa tambo dzimwe nguva kunogona kubatsira kumisa kukanganisa.
Chii chinonzi EMC?
Iwe unofanirwa kuziva emc kugadzira zvakanaka zvemagetsi. EMC inomirira electromagnetic kuenderana. Inoratidza kuti mudziyo wako unoshanda sei pasina kukonzera kana kukanganiswa. Kana yako pcb marongerwo akasangana emc mitemo, chigadzirwa chako chichapfuura miedzo uye kushanda pedyo nemamwe magetsi. EMC ine zvikamu zviviri: emission uye kusadzivirirwa. Emission ndiyo inotumirwa nemudziyo wako. Kusadzivirira ndiko kuti mudziyo wako unovhara sei masaini ekunze. Gadzira emc kutanga kudzivirira zvinodhura zvinogadzirisa gare gare.
