1. I-Anti-static

Imboni yokuhlanganisa isibonisi kufanele ibe nezinyathelo ezinhle zokulwa ne-static.Inhlabathi enikelwe emelene ne-static, i-anti-static floor, i-anti-static soldering iron, i-anti-static table mat, indandatho enganyakazi, izingubo ezingaguquguquki, isilawuli somswakama, ukubeka phansi okokusebenza (ikakhulukazi i-foot cutter), njll. konke kuyisisekelo izidingo, futhi kufanele ihlolwe njalo ngemitha emile .

2. Shayela umklamo wesifunda

Ukuhlelwa kwe-IC yomshayeli ebhodini lesekethe yomshayeli kumojuli yesibonisi kuzophinde kuthinte ukukhanya kwe-LED.Njengoba amandla okukhiphayo e-IC yomshayeli asakazwa ngebanga elide ebhodini le-PCB, ukwehla kwamandla kagesi endlela yokudlulisela kuzoba kukhulu kakhulu, okuzothinta i-voltage evamile yokusebenza ye-LED futhi kubangele ukukhanya kwayo kwehle.Sivame ukuthola ukuthi ukukhanya kwama-LED azungeze imojuli yesibonisi kuphansi kunaphakathi nendawo, okuyisizathu.Ngakho-ke, ukuze uqinisekise ukuhambisana kokukhanya kwesikrini sokubonisa, kuyadingeka ukuklama umdwebo wokusabalalisa wesifunda somshayeli.

3. Dizayina inani lamanje

Amandla amanje we-LED angama-20mA.Ngokuvamile, kunconywa ukuthi umkhawulo wamanje osebenzayo ungabi ngaphezu kwama-80% yenani legama.Ikakhulukazi kwizibonisi ezinokuphakama kwechashazi elincane, inani lamanje kufanele lehliswe ngenxa yezimo ezimbi zokulahla ukushisa.Ngokusho kokuhlangenwe nakho, ngenxa yokungaguquguquki kwejubane lokunciphisa ama-LED abomvu, aluhlaza, naluhlaza okwesibhakabhaka, inani lamanje lama-LED aluhlaza okwesibhakabhaka nokuluhlaza kufanele lehliswe ngendlela eqondiwe ukuze kugcinwe ukuvumelana kwebhalansi emhlophe yesikrini sokubonisa. ngemva kokusetshenziswa isikhathi eside.

4. Izibani ezixubile

Ama-LED ombala ofanayo namaleveli okukhanya ahlukene adinga ukuxutshwa, noma afakwe ngokuvumelana nomdwebo wokufaka ukukhanya oklanywe ngokuvumelana nomthetho ohlukile ukuze kuqinisekiswe ukufana kokukhanya kombala ngamunye kusikrini sonke.Uma kunenkinga kule nqubo, ukukhanya kwendawo kwesibonisi kuzobe kungahambisani, okuzothinta ngokuqondile umphumela wokubonisa wesibonisi se-LED.

5. Lawula ukuma kwesibani

Kuma-LED asemgqeni, kufanele kube nobuchwepheshe benqubo eyanele ukuze kuqinisekiswe ukuthi i-LED i-perpendicular ebhodini le-PCB lapho idlula isithando somlilo.Noma yikuphi ukuchezuka kuzothinta ukungaguquguquki kokukhanya kwe-LED esethiwe, futhi amabhulokhi ombala anokukhanya okungahambisani azovela.

6. Izinga lokushisa le-wave soldering kanye nesikhathi

Izinga lokushisa kanye nesikhathi sokushisela amagagasi angaphambili kufanele kulawulwe ngokuqinile.Kunconywa ukuthi izinga lokushisa langaphambi kokushisa libe ngu-100℃±5℃, futhi izinga lokushisa eliphakeme kakhulu akufanele lidlule ku-120℃, futhi izinga lokushisa langaphambi kokushisa kufanele likhuphuke ngokushelela.Izinga lokushisa lokushisela lingu-245℃±5℃.Kunconywa ukuthi isikhathi akufanele sidlule imizuzwana emi-3, futhi ungadlidlizi noma ushaqise i-LED ngemva kwesithando somlilo ize ibuyele ekushiseni okujwayelekile.Imingcele yokushisa yomshini we-wave soldering kufanele ihlolwe njalo, okunqunywa izici ze-LED.Izinga lokushisa elishisayo noma eliguquguqukayo lizolimaza ngokuqondile i-LED noma libangele izinkinga zekhwalithi efihliwe, ikakhulukazi kuma-LED angama-oval anosayizi omncane njengo-3mm.

7. Ukulawula ukushisela

Uma isibonisi se-LED singakhanyi, kuvame ukuba namathuba angaphezu kuka-50% okuthi kubangelwe izinhlobo ezihlukahlukene zokudayiswa kwe-virtual, ezifana ne-LED pin soldering, i-IC pin soldering, i-pin header soldering, njll. Ukuthuthukiswa kwalezi zinkinga kudinga ukuthuthukiswa okuqinile kwenqubo kanye nokuhlolwa kwekhwalithi okuqinisiwe ukuze kuxazululwe.Ukuhlolwa kokudlidliza ngaphambi kokushiya imboni nakho kuyindlela enhle yokuhlola.

8. Umklamo wokukhipha ukushisa

I-LED izokhiqiza ukushisa lapho isebenza, izinga lokushisa eliphezulu kakhulu lizothinta isivinini sokuncisha amandla nokuzinza kwe-LED, ngakho-ke umklamo wokukhipha ukushisa webhodi le-PCB kanye nomklamo wokungenisa umoya nokushisa wekhabhinethi uzothinta ukusebenza kwe-LED.
