Q: Ayini amasu we-ESD ekuhlolweni kwe-EMC yemikhiqizo ephelele yokugcina?
A: Isixazululo esiphelele ukugeleza ugesi ophelele emhlabathini. Kuneziphakamiso ezilandelayo:
1), Ukuhlinzekwa kwamandla kanye ne-TV TV TV TV: Ukuvikelwa kwamandla kwe-VCC Amandla, i-TVS tube ingaxhunyaniswa futhi ixazululwe. I-TV TV TUBE ifana kakhulu ne-voltage Regulator Diode. Ine-voltage ekalwe. Umehluko ukuthi isivinini sayo sokuphendula sishesha kakhulu futhi sinomphumela omuhle wokukhululeka kugesi kagesi.
2) Ukuvikelwa kwe-ESD yomugqa wesiginali wangaphandle: Ungabheka futhi uxhume i-diode ehlekisayo ukuqondisa okwamanje ekunikezelweni kwamandla noma emhlabathini;
3), ukuhlunga kwe-LC kufakwa ekuhlinzekweni kwamandla kwamadivayisi abucayi: Ezinye i-IC zithambekele kakhulu kugesi we-static. Lapho ukuhlolwa kwe-ESD kwenziwa, setha kabusha kabusha noma ukufa kwenzeka njalo. Isizathu ukuthi i-PIN ye-Power Supply ivame ukuphazamiseka. Kulokhu, ukuhlunga kwe-LC kungangezwa ekunikezelweni kwamandla ayo.
4) Izidingo ze-PCB ezihamba ngezinyawo: I-PCB kufanele ivezwe ngangokunokwenzeka. Uma kuyiphaneli ephindwe kabili, zombili izinhlangothi kufanele zifakwe ngethusi endaweni enkulu, futhi kufanele kube nezimbobo ezanele zomhlaba. Uma kuyibhodi elinobungqingili noma ngaphezulu, ungqimba oluseduze lwendiza yengxenye enkulu kufanele isethwe ekwakhekeni.
5) Izidingo Zokubekwa: Ukukhipha ngempumelelo ugesi we-tuli, kufanele kuqinisekiswe isisekelo esihle. Isibonelo, ama-elekthronikhi wezokwelapha, imikhiqizo ejwayelekile yezokwelapha yezokwelapha enjengeziqapheli, kuzoba nesisekelo esilinganayo sokuphela ngemuva kwe-fuselage. Lapho wenza izivivinyo ze-ESD, ukuphela kwalesi sisekelo kuxhumeke emhlabeni, ngakho-ke kunendlela yokukhipha ugesi we-Static.
I-6) I-PCB Layout Wiring: Uma i-capacitor ye-chip ikude kakhulu ne-PIN ye-chip, umphumela wokukhohlisa uzolahleka. Uma umugqa wezimpawu ezibucayi yinde kakhulu, kuzokwethulwa imali engalindelekile ye-electromagnetic. Ngokwe-anti-esd, amadivaysi abucayi noma imigqa yesiginali (efana nokusetha kabusha) kufanele igcinwe kude namaphethelo we-PCB ukuvikela ukuphuma komoya ekuphazanyisweni ngqo namadivayisi nemigqa yesiginali. Unqenqemeni lwe-PCB kufanele lube nobubanzi obuthile begebe noma ithusi.
