I-UV LED PCB: Gcwalisa Umhlahlandlela Wezobuchwepheshe Wezicelo Zobuchwepheshe

Iyini i-UV LED PCB Technology

I-UV LED PCB isho amabhodi esekethe aphrintiwe akhethekile aklanyelwe ukushayela futhi asekele ama-diode akhipha ukukhanya kwe-ultraviolet yonkana i-UV-A (315-400nm), i-UV-B (280-315nm), kanye ne-UV-C (200-280nm) ububanzi begagasi. Lawa mabhodi esekethe asebenza njengesisekelo sezinhlelo zokuphulukisa ze-UV, imishini ye-phototherapy yezokwelapha, imishini yokuvala inzalo, nemishini yokuchayeka ezimbonini.

Ngokungafani nama-PCB e-LED avamile , amabhodi wesekethe aphrintiwe nge-UV LED kumele abhekane nokuqina okuphezulu kokushisa, izidingo zokuphathwa kwamandla eziqinile, kanye nezidingo zokuqina kwamaza okukhanya okuthinta ngqo ukusebenza kwesicelo kanye nokuphila isikhathi eside kwengxenye.

Isakhiwo se-UV LED PCB kanye Nomgomo Wokusebenza

Izingxenye Zesakhiwo Esiyisisekelo

I-UV LED PCB ngokuvamile ihlanganisa izendlalelo ezintathu ezihlanganisiwe ezisebenza ndawonye ukuze kuzuzwe ukusebenza okuhle. Isendlalelo se-substrate sisebenzisa izinto ezisekelwe ku-aluminium, ama-substrate e-ceramic, noma izakhiwo ze-copper-core ezikhethelwe izici ezisezingeni eliphezulu ze-thermal conductivity. Imaski ye-solder kanye nezendlalelo ezikhanyayo zidinga ukwakheka kwe-UV ukuze kuvinjelwe ukuwohloka nokugcina ukusebenza kahle kokubona ngaphansi kokuchayeka kwe-ultraviolet okuqhubekayo.

Ukusebenza Isimiso

Umgomo wokusebenza ubandakanya ugesi ogeleza ngokusebenzisa imikhondo yethusi eklanywe ngokunemba ukuze unike amandla ama-chips e-LED, aguqula amandla kagesi abe ama-photon e-ultraviolet. I-UV LED PCB ilawula kanyekanye ukusatshalaliswa kukagesi ngenkathi ihambisa ukushisa okulahlwayo kude nendawo ehlanganayo, igcina izinga lokushisa elilungile lokusebenza ngaphansi kuka-85°C ukuze usebenze okuthembekile.

Ukucatshangelwa Okubalulekile Kwedizayini yama-PCB e-UV LED

I-Thermal Management Architecture

Ukuphathwa okushisayo kumelela ipharamitha yokuklama ebaluleke kakhulu ekuthuthukisweni kwe-UV LED PCB. Izinga lokushisa lendawo ehlanganayo lithinta ngokuqondile kokubili ukusebenza kahle kokukhipha ukukhanya nempilo yokusebenza, edinga izakhiwo ezishisayo ezihlanganisa izinto ze-substrate ezine-thermal conductivity engaphezu kuka-2 W/m·K. Ama-Aluminium substrates ngokuvamile ahlinzeka ngo-1.5-3 W/m·K, kuyilapho izinketho ze-ceramic njenge-aluminium nitride ziletha amanani angaphezu kuka-20 W/m·K kuzinhlelo zokusebenza zamandla aphezulu.

Izindlela zokushabalalisa ukushisa kumele zinciphise ukumelana nokushisa kuzo zonke izixhumi kusukela ekuhlanganeni kwe-LED kuya ku-substrate kuya ekushiseni kwangaphandle. Imiklamo ye-UV LED PCB ethuthukisiwe ifaka ama-vias okushisa, ubuchwepheshe bezinhlamvu zethusi, noma izendlalelo zethusi eziboshwe ngqo ukuthuthukisa ukusebenza kahle kokusabalalisa ukushisa.

Isakhiwo sikagesi kanye Nokusabalalisa Kwamanje

Isakhiwo sikagesi sama-PCB e-UV LED sidinga amashaneli abashayeli abazimele ngentambo ngayinye ye-LED noma ye-LED ukuze kuvinjelwe ukungalingani kwamanje. Ugqinsi lwe-Copper trace ngokuvamile lucacisa ubuncane besisindo sethusi esingu-2 oz, nokulandela okubanzi nezindlela ezimfishane zomzila ezinciphisa ukulahlekelwa okuphikisayo. Ukunqanyulwa kokuphakelwa kwamandla kanye nokwakhiwa kwendiza yaphansi kunciphisa i-impedance yendlela yokubuya ngenkathi kugcinwa ukuhambisana kwe-electromagnetic.

Ukukhetha Okubalulekile kwezicelo ze-UV

Ukukhetha okubalulekile kwama-PCB e-UV LED kubhekana nezinselelo eziyingqayizivele ezidalwa ukuchayeka emisebeni ye-ultraviolet. Imaski ye-solder kufanele imelane nokuwohloka kwe-photochemical isebenzisa ukwakheka okukhethekile kwe-UV okuvimbela ukuphuzi nokuwohloka komshini. Izendlalelo ze-Dielectric insulation zilinganisa ukuqhutshwa kokushisa phakathi kuka-2-5 W/m·K ngokumelene nezidingo zokuhlukaniswa kukagesi, ezinogqinsi olusuka kuma-microns angu-50 kuya kwangu-150 kuye ngokucaciswa kwamandla kagesi.

Idizayini ye-Optical and Reflective Layer

Izendlalelo ezikhanyayo ezizungeze ama-LED e-UV kufanele zisebenzise izinto ezinokukhanya okuphezulu kwe-UV-spectrum kuyilapho zibonisa ukumelana nokuguquguquka. Oyinki abakhanyayo abamhlophe abakhelwe ngokukhethekile izinhlelo zokusebenza ze-UV bahlinzeka ngokusebenza okuphezulu. Ukukhetha kokuqedwa kwendawo kuthanda isiliva lokucwiliswa noma i-nickel ecwiliswa ngegolide elingenawo ugesi ngaphezu kwezivimbelakuvunda ze-organic solderability ezingase ziwohloke ngaphansi kokuchayeka kwe-UV.

Ukwethembeka kanye Nezici Zokuphila

Ukuthembeka kwesikhathi eside kuncike ekuzinzeni kwezinto ezibonakalayo kanye nokulawulwa kokucindezeleka okushisayo. Zonke izingxenye kufanele zimelane nokuhamba ngebhayisikili okushisayo okuphindaphindiwe ngaphandle kwe-delamination noma ukukhathala kwe-solder. Izembatho ezivikelayo ezihambisanayo zisiza ukuvimbela ukubola kanye nokuwohloka okubangelwa yi-UV. Ukusebenzisa ama-RoHS athobelayo, ama-solder ashisa kakhulu athuthukisa ubuqotho obuhlangene, kuyilapho ukuhlolwa okuqinile kokushiswa nokusheshisa ukuguga kuqinisekisa ukungaguquguquki kokusebenza.

Ngokulungiselela ukunqanyulwa kokushisa, ukufana kukagesi, nezinto ezimelana ne-UV, abaklami banganweba kakhulu isikhathi sokusebenza semihlangano ye-UV LED futhi baqinisekise ukuphuma okubonakalayo okuqhubekayo ezinkulungwaneni zamahora.
