Duk da haka, aikace-aikacen motoci sau da yawa suna buƙatar ƙarin cancanta don girgiza, danshi, da tsawaita rayuwa a ƙarƙashin takamaiman yanayin gwaji (misali, AEC-Q102). Wannan takardar bayanai na yau da kullun ba ta da'awar irin waɗannan cancantattun. Don amfani da motoci, tuntuɓi masana'anta don bayanan da suka dace da matakin.

9.4 Shin Zan iya Amfani da Solder Reflow Don Wannan Kayan?

Takardar bayanai ta bayyana a sarari cewa "IR reflow ba tsari bane da ya dace da nau'in fitilar LED ta cikin rami." An ƙera wannan kayan don solder wave ko hanyoyin solder da hannu kawai.

No.The datasheet explicitly states that "IR reflow is not suitable process for through-hole type LED lamp product." This component is designed for wave soldering or hand soldering processes only.
