Umucyo wa smd usobanura iki?

Hamwe no gukundwa kwicyerekezo cya "nta rumuri nyamukuru rumurika", ibicuruzwa bya LED umurongo wumurongo ugenda urushaho gukundwa mugushushanya amazu hamwe nimishinga yo gutunganya inzu yose. Hano haribintu bitatu bisanzwe LED yoroheje yumucyo wibicuruzwa kumasoko, aribyo imirongo ya SMD LED yumucyo, imirongo yumucyo wa COB LED hamwe nu mucyo wa CSP LED uheruka. Nubwo buri gicuruzwa gifite ibyiza byacyo nibitandukaniro, umwanditsi azagerageza gukoresha ingingo imwe kugirango yumve itandukaniro riri hagati yibi bitatu, kugirango ubashe guhitamo neza.

SMD imirongo yumucyo, izina ryuzuye ryibikoresho byububiko bwa Surface (Surface Mounted Devices) imirongo yumucyo, bivuga chip ya LED ishyirwa kumurongo wa substrate yumucyo, hanyuma igapakirwa kugirango ibe umurongo wamasaro mato mato. Ubu bwoko bwurumuri ni ubwoko busanzwe bwa LED yumucyo, ubusanzwe ufite ibiranga guhinduka, kunanuka, kuzigama imbaraga, no kuramba.

SMD ni impfunyapfunyo ya "Surface Mount Device", ni bwo bwoko bwibikoresho bya LED kuri ubu ku isoko. Chip ya LED yashyizwe mubikonoshwa bya LED hamwe na fosifori hanyuma bigashyirwa ku kibaho cyoroshye cyacapwe (PCB). SMD LED imirongo irazwi cyane kubera byinshi. , Ibikoresho bya SMD LED biza mubunini butandukanye: 3528, 5050, 2835, 3014, 2216, 2110; muri rusange bitwa ukurikije ubunini bwabo, urugero, ubunini bwa 3528 ni 3.5 x 2.8mm, 5050 ni 5.0 x 5.0mm, naho 2835 ni 2.8 x 3.5mm, 3014 ni 3.0 x 1.4mm.

Kubera ko imirongo isanzwe ya SMD LED yoroheje ikoresha ibice bitandukanye bya SMD LED, intera / ikinyuranyo hagati yibikoresho bibiri byegeranye bya LED ni binini. Iyo itara ryaka ryaka, urashobora kubona ingingo zumucyo. Abantu bamwe bavuga ngo Kubibanza bishyushye cyangwa byingenzi. Niba rero udashaka kubona ahantu hashyushye cyangwa ahantu hashyushye, ugomba gukoresha ibikoresho bitwikiriye (nkigifuniko cya plastiki) kugirango ubishyire hejuru yumurongo wa SMD LED, kandi ugomba gusiga uburebure buhagije kugirango uvange urumuri kugirango ugabanye ibibatsi byaka Ingaruka nziza, bityo imyirondoro ya aluminiyumu isanzwe ikoreshwa ni ndende.

COB itara ryumucyo, izina ryuzuye ni Chips Kumurongo LED urumuri rwumucyo, ni ubwoko bwurumuri rwa LED hamwe na chip kumupaki wibibaho (Chips On Board). Ugereranije nu mucyo wa SMD, imirongo yumucyo ya COB ipakira mu buryo butaziguye ibyuma byinshi bya LED ku kibaho cy’umuzunguruko kugira ngo habeho ubuso bunini butanga urumuri, ubusanzwe bukoreshwa mu bihe bisaba urumuri rumwe.

Bitewe nuburinganire bwa fosifori buhoraho, imirongo ya COB LED irashobora gusohora urumuri rumwe rutagira urumuri rugaragara cyane, bityo rero rushobora gusohora urumuri rusa neza kandi rukaba rutarinze gukenera ibifuniko bya plastike. , niba ukeneye gukoresha aluminiyumu, urashobora guhitamo imyirondoro yoroheje ya aluminium.

CSP ni bumwe mu buhanga bugezweho mu nganda za LED. Mu nganda za LED, CSP bivuga ifoto ntoya kandi yoroshye idafite pake cyangwa insinga ya zahabu. Bitandukanye na tekinoroji ya SMD yumucyo, CSP ikoresha udushya twizunguruka-twizunguruka FPC imbaho ​​zoroshye.

F. Ifite ibyiza byo koroshya, kugoreka kubuntu no kugundwa, ubunini buke, ubunini buto, busobanutse neza, hamwe nubushobozi bukomeye.

Ugereranije nububiko bwa gakondo bwa SMD, ipaki ya CSP ifite inzira yoroshye, idakoreshwa cyane, igiciro gito, kandi impande zitanga urumuri nicyerekezo nini cyane kuruta ubundi buryo bwo gupakira. Bitewe nuburyo bwihariye bwo gupakira, imirongo yumucyo ya CSP irashobora kuba ntoya, yoroshye kandi yoroshye, kandi ifite ingingo ntoya yo kugunama. Muri icyo gihe, inguni yacyo itanga urumuri nini, igera kuri 160 °, kandi ibara ryoroheje rifite isuku kandi ryoroshye, nta mpande z'umuhondo. Ikintu kinini kiranga urumuri rwa CSP nuko badashobora kubona urumuri kandi rworoshye kandi rwijimye.
