10. Tambayoyin da ake yawan yi (Bisa Siffofin Fasaha)

Q1: Menene halin yanzu na aiki da aka ba da shawarar?

A1: Matsakaicin halin yanzu na ci gaba shine 30mA. Matsakaicin wurin aiki na al'ada shine 20mA, wanda shine daidaitaccen yanayin gwaji don jerin ƙayyadaddun bayanai na gani (ƙarfin haske, launi). Yin aiki a 20mA yana ba da daidaitaccen ma'auni na haske, inganci, da tsawon rai.

Q2: Ta yaya zan fassara rukunonin ƙarfin haske (T, U, V)?

A2: Waɗannan rukunoni suna ba da garantin mafi ƙarancin fitar da haske. Misali, yin oda daga Rukunin V yana tabbatar da cewa kowane LED zai sami aƙalla 11250 mcd a 20mA. Wannan yana da mahimmanci ga aikace-aikacen da dole ne a cika mafi ƙarancin matakin haske. Rukunoni suna ba masu ƙira damar zaɓar matakin aiki mai dacewa da farashi.

Q3: Zan iya tuƙa wannan LED da wadataccen 5V?

A3: Ba kai tsaye ba tare da resistor mai iyakance halin yanzu. Ƙarfin lantarki na gaba (Vf) yana tsakanin 2.8V da 3.6V. Haɗa 5V kai tsaye zai haifar da halin yanzu mai yawa, yana lalata LED. Dole ne ku lissafta kuma ku yi amfani da resistor na jerin: R = (Wadataccen Ƙarfin Lantarki - Vf) / I_F. Yin amfani da Vf na al'ada na 3.2V da I_F=20mA tare da wadataccen 5V: R = (5 - 3.2) / 0.02 = 90 Ohms.

Q4: Menene ma'anar ƙimar ESD na 4KV don sarrafawa?

A4: Yana nufin LED ɗin yawanci zai iya jure watsawar lantarki na 4000V bisa ga Tsarin Jikin Mutum (HBM) ba tare da lalacewa ba. Duk da cewa wannan yana da ƙarfi, yana da mahimmanci a bi ƙa'idodin yin taka-tsantsan na ESD yayin sarrafawa da haɗawa (misali, amfani da tashoshin aiki masu tushe, igiyoyin wuyan hannu) don hana lalacewa ta tarawa ko lahani na ɓoye.

Q5: Yaya mahimmanci ne mafi ƙarancin nisa na 3mm don solder/lanƙwasa jagora?

A5: Yana da mahimmanci sosai. Resin epoxy da haɗin waya na ciki kusa da gindin kunshin suna da hankali ga zafi da damuwa na injiniya. Keta wannan nisa na iya haifar da gazawar nan take (fashewar resin, karyewar haɗin) ko matsalolin amincin dogon lokaci (raguwar fitar da haske, gazawar da ba ta daɗe ba).
