1. Cob waa mid ka mid ah nalalka LED-ka.Cob waa soo gaabinta chip on board, taas oo macnaheedu yahay in chip si toos ah u xidhan yahay oo baakad on substrate oo dhan, iyo N chips ayaa la isku daray si loo baakado.Inta badan waxaa loo isticmaalaa in lagu xalliyo dhibaatooyinka soo saarista awoodda sare ee LED oo leh jajabyo yar yar, kaas oo kala firdhi kara kuleylka kuleylka, hagaajinta iftiinka iftiinka, iyo hagaajinta saameynta iftiinka nalalka LED;Cufnaanta qulqulka nalka cob waa sarreeyaa, dhalaalku waa hooseeyaa, iftiinkuna waa jilicsan yahay.Waxay soo saartaa iftiin si siman loo qaybiyey.Waqtigan xaadirka ah, waxaa si weyn loogu isticmaalaa nalalka, iftiinka iftiinka, nalalka hoose, nalalka dhaadheer, nalalka waddooyinka iyo nalalka kale;
2. Marka laga soo tago cob, waxaa jira SMD oo ku jirta warshadaha nalalka LED, taas oo ah soo gaabinta qalabka dusha sare ee dusha sare, taas oo macnaheedu yahay in dusha sare ee laydhka iftiiminaya ay leeyihiin xagal weyn oo iftiin leh, kaas oo gaari kara 120-160 darajo.Marka la barbardhigo baakadaha hore ee plug-in, SMD waxay leedahay sifooyinka waxtarka sare leh, saxnaanta wanaagsan, heerka alxanka beenta ah ee hooseeya, miisaanka fudud iyo mugga yar;
3. Intaa waxaa dheer, mcob, taas oo ah, chips muilti on board, taas oo ah, baakadaha isku dhafan ee dusha badan, waa ballaarinta habka baakadaha cob.Baakadaha Mcob waxay si toos ah ugu dhejisaa jajabyada koobabka indhaha, dahaadhida fosfooraska ee hal jajab kasta iyo dhamaystirka qaybinta iyo hababka kale ee iftiinka chip LED wuxuu ku urursan yahay koobka.Si loo sameeyo iftiin badan oo soo baxa, inta badan laydhka, ayaa kor u kacaya waxtarka iftiinka.Waxtarka baakadaha quwadda hoose ee mcob guud ahaan wuu ka sarreeyaa baakadaha quwadda sareeyo.Waxay si toos ah ugu dhejisaa jajabka weelka kulaylka substrate birta, si ay u soo gaabinayso dariiqa kuleylka kuleylka, yareyso caabbinta kulaylka, hagaajinta saameynta kulaylka, iyo si wax ku ool ah u yareyso heerkulka isku dhafka ee chip-ka-baxa.
