I-LED yangaphakathi ye-SMDizikrini manje zingamandla amakhulu kubuchwepheshe bokubonisa basendlini, ikakhulukazi izinhlobo ezincane zephimbo eziyingxenye yezilungiselelo ezifana namagumbi enkomfa nezikhungo zokulawula. Ekuqaleni, lezi zikrini zisebenza ngokungenasici, kodwa ngokuhamba kwesikhathi, izinkinga ezifana nokuhluleka kwezibani zingenzeka. Ngaphandle kokuguga kwemvelo, izici ezifana nemithelela yengozi noma ukuphatha okungafanele ngesikhathi sokufakwa nakho kungaholela ekulimaleni. Izindawo ezinomswakama zandisa ingozi yomonakalo.
Kwalabaizikrini ezincane ze-LED zasendlini, ukuhlolwa okuqinile kuyadingeka ngemva kwezinyanga okungenani eziyisithupha ukuze kuqinisekiswe ubuqotho babo. Enye yezinselelo ezibalulekileAbakhiqizi bezikrini ze-LEDibhekana nomonakalo odalwe umswakama, uthuli, nemithelela yomzimba, kuyilapho ithuthukisa ukuqina komkhiqizo futhi inciphisa izindleko zokuwulungisa. Ukwethulwa kobuchwepheshe be-GOB (Glue On Board) kunikeza isisombululo esithembisayo.
Le ndlela emisha ihilela ukusebenzisa ungqimba lweglue phezu kwebhodi lesibani inqubo yokuguga yamahora angu-72. Lokhu akuvikeli kuphela isisekelo sesibani kumswakama kodwa futhi kuqinisa isikrini ngokumelene nokulimala ngokomzimba. Ngenkathi izikrini ezijwayelekile ze-LED zasendlini ngokuvamile zine-Isilinganiso se-IP40, ubuchwepheshe be-GOB bukhuphula kakhulu amandla abo okuvikela ukungena ngaphandle kwezindleko ezikhuphuka kakhulu, ukuhambisana kahle nokulindelwe yimakethe kanye nokuba nokwenzeka kokukhiqiza.
Ukuqina kwebhodi le-PCB akunakwa. Igcina izinqubo zayo ezintathu eziqinile zokuvikela upende. Izithuthukisi zihlanganisa ukufafaza ngemuva kwebhodi le-PCB ukuphakamisa amazinga okuvikela nokusebenzisa i-coating phezu kwendawo ye-IC ukuze kuvikelwe izingxenye zesekethe ehlanganisiwe yedrayivu ekuhlulekeni. Le ndlela ebanzi iqinisekisa ukuthi kokubili ngaphambili nangemuva kwezikrini ze-LED kuvikelwe kahle, kunweba impilo yazo yokusebenza nokwethembeka.
