6. Wave soldering zafin jiki da lokaci

Dole ne a sarrafa zafin jiki da lokacin walƙiya na gaba.Ana ba da shawarar cewa zafin jiki na preheating shine 100 ℃ ± 5 ℃, kuma mafi girman zafin jiki kada ya wuce 120 ℃, kuma zafin zafin jiki na preheating dole ne ya tashi lafiya.A waldi zafin jiki ne 245 ℃ ± 5 ℃.Ana ba da shawarar cewa lokacin kada ya wuce daƙiƙa 3, kuma kar a girgiza ko girgiza LED bayan tanderun har sai ya dawo zuwa yanayin zafi na yau da kullun.Ya kamata a duba sigogin zafin jiki na injin siyar da igiyoyin ruwa akai-akai, wanda aka ƙaddara ta halayen LED.Zazzaɓi mai zafi ko sauye-sauyen zafin jiki zai lalata LED ɗin kai tsaye ko haifar da matsalolin ingancin ɓoyayyiya, musamman ga ƙananan girman zagaye da ledoji masu tsayi kamar 3mm.

7. Kula da walda

Lokacin da nunin LED ba ya haskakawa, akwai sau da yawa fiye da 50% yiwuwar cewa an haifar da shi ta hanyar nau'ikan nau'ikan kayan aikin kama-da-wane, irin su LED fil soldering, IC fil soldering, fil soldering, da dai sauransu. m inganta tsarin da kuma ƙarfafa ingancin dubawa don warware.Gwajin girgiza kafin barin masana'anta kuma hanya ce mai kyau ta dubawa.

8. Zane-zanen zafi

LED zai haifar da zafi lokacin da yake aiki, yawan zafin jiki mai yawa zai shafi saurin attenuation da kwanciyar hankali na LED, don haka zafin zafi na PCB board da kuma samun iska da zafin jiki na majalisar ministocin zai shafi aikin LED.
