A: A'a. Haɗa shi kai tsaye zuwa 5V zai tilasta halin yanzu wanda ya wuce matsakaicin ƙimar sa, yana haifar da gazawar nan take da mummunan. Koyaushe ana buƙatar resistor mai iyakancewa na halin yanzu ko direba mai dorewa.

Q: Me yasa yanayin ajiya bayan buɗe jakar yake da tsauri haka?
A> Fakitin SMD LED na iya sha danshi daga iska. Yayin tsarin gudanar da reflow mai zafi, wannan danshin da aka kama yana canzawa zuwa tururi da sauri, yana haifar da matsa lamba na ciki wanda zai iya lalata fakitin ko fashe da mutuwa. Rayuwar bene na sa'o'i 168 da hanyoyin gasa hanyoyin daidaitattun hanyoyi ne don hana wannan yanayin gazawar.
