I-SMT ne-SMD: Ubuchwepheshe bokupakisha be-LED

Isibonisi se-SMT LED

I-SMT, noma ubuchwepheshe be-surface mount, ubuchwepheshe obufaka ngokuqondile izingxenye ze-elekthronikhi ebusweni bebhodi lesekethe. Lobu buchwepheshe abunciphisi nje kuphela ubukhulu bezingxenye ze-elekthronikhi zendabuko kuya kwezimbalwa eziyishumi, kodwa futhi kufinyelela ukuminyana okuphezulu, ukuthembeka okuphezulu, i-miniaturization, izindleko eziphansi, nokukhiqizwa okuzenzakalelayo komhlangano womkhiqizo we-elekthronikhi. Enqubweni yokukhiqiza izikrini zokubonisa ze-LED, ubuchwepheshe be-SMT budlala indima ebalulekile. Kufana nomdwebi onekhono okhweza ngokunembile amashumi ezinkulungwane zama-chips e-LED, ama-driver chips nezinye izingxenye ebhodini lesifunda lesikrini esibonisiwe, enze “imizwa” kanye “nemithambo yegazi” yesikrini sokubonisa se-LED.

Izinzuzo ze-SMT:

• Ukusebenza Kwesikhala:I-SMT ivumela izingxenye eziningi ukuthi zibekwe ku-PCB encane, okuvumela ukukhiqizwa kwemishini kagesi ehlangene futhi engasindi.
• Ukusebenza Okuthuthukisiwe:Ngokunciphisa ibanga okumele amasignali kagesi alihambe, i-SMT ithuthukisa ukusebenza kwamasekhethi kagesi.
• Ukukhiqiza Okungabizi kakhulu:I-SMT ilungele ukuzenzela, okunciphisa izindleko zabasebenzi futhi kukhuphule ukusebenza kahle kokukhiqiza.
• Ukwethembeka:Izingxenye ezifakwe kusetshenziswa i-SMT mancane amathuba okuthi zixege noma zinqanyulwe ngenxa yokudlidliza noma ukucindezeleka komshini.

Isikrini se-SMD LED

I-SMD, noma idivayisi yokukhweza ngaphezulu, iyingxenye ebalulekile yobuchwepheshe be-SMT. Lezi zingxenye ezenziwe nge-miniaturized, "njengenhliziyo encane" yezikrini zokubonisa ze-LED, zinikeza amandla aqhubekayo esikrini sokubonisa. Kunezinhlobo eziningi zamadivayisi e-SMD, okuhlanganisa ama-chip transistors, amasekhethi ahlanganisiwe, njll. Asekela ukusebenza okuzinzile kwezikrini zokubonisa ze-LED ezinosayizi wazo omncane kakhulu nemisebenzi enamandla. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukusebenza kwamadivayisi e-SMD nakho kuhlala kuthuthuka, kuletha ukukhanya okuphezulu, i-gamut yombala ebanzi nempilo yesevisi ende kuzikrini zokubonisa ze-LED.

Izinhlobo zezingxenye ze-SMD:

• Izingxenye ze-Passive:Njengama-resistors, ama-capacitor, nama-inductors.
• Izingxenye Ezisebenzayo:Kubandakanya ama-transistors, ama-diode, namasekethe ahlanganisiwe (ICs).
• Izingxenye ze-Optoelectronic:Njengama-LED, ama-photodiode, nama-laser diode.

Izinhlelo zokusebenza ze-SMT ne-SMD kuzibonisi ze-LED

Izinhlelo zokusebenza ze-SMT ne-SMD kuzibonisi ze-LED ziningi futhi ziyahlukahluka. Nazi izibonelo ezimbalwa eziphawulekayo:

• Amabhodi e-LED wangaphandle:Ama-LED ama-SMD akhanya kakhulu aqinisekisa ukuthi izikhangiso nolwazi lubonakala ngokucacile ngisho nalapho kukhanya ilanga.
• Izindonga zevidiyo zasendlini:I-SMT ivumela izibonisi ezinkulu ezingenamthungo ezinokulungiswa okuphezulu, ezifanele imicimbi, amagumbi okulawula, nezilungiselelo zebhizinisi.
• Imibukiso yokudayisa:Idizayini encane futhi engasindi enikwe amandla ubuchwepheshe be-SMT kanye ne-SMD yenza kube nokwenzeka ukudala izibonisi ezihehayo neziguqukayo ezindaweni zokuthengisa.
• Ubuchwepheshe obugqokekayo:Izibonisi ze-LED eziguquguqukayo kumadivayisi agqokekayo azuza kumvelo ehlangene futhi engasindi yezingxenye ze-SMD.

Isiphetho

I-Surface-Mount Technology (SMT) kanye ne-Surface-Mount Devices (SMD) aguqule imboni yokubonisa i-LED, enikeza izinzuzo ezibalulekile mayelana nokusebenza, ukusebenza kahle, kanye nokuguquguquka. Njengoba ubuchwepheshe buqhubeka buthuthuka, singalindela okunye okusha kanye nentuthuko ekufakweni kwesibonisi se-LED, okuqhubeza ukuthuthukiswa kwezixazululo ezibukwayo eziyinkimbinkimbi nakakhulu nezinomthelela.

Ngokwamukela ubuchwepheshe be-SMT kanye ne-SMD, abakhiqizi nabaklami bangakha izibonisi ze-LED ezisezingeni eliphezulu ezihlangabezana nezidingo eziguqukayo zezimboni ezihlukahlukene, baqinisekise ukuthi ukuxhumana okubukwayo kuhlala kucacile, kunamandla, futhi kusebenza ngempumelelo.
