970nm IR LED SMT 2835 SMD LED Infrared

Xirmada LED-ka ee 2835 SMD oo leh 970nm LED Emitter;

Heerkulka sare wuxuu gubi doonaa LED-yada SMD ama nalalka LED-ka-daloolka marka ay shaqeynayaan. LED-ku waa la dili doonaa ama waa dhaawacmi doonaa haddii kulaylku aanu kala qaybin karin waqtigii loogu talagalay marka ay shaqaynayaan. Xaaladdan oo kale, kuma talineyno in dadku isticmaalaan nalalka LED-ka ee hadda jira ee hawlgalka sare leh. Sida 1W korantada sare ee LED oo leh 5mm xirmo-hole LED ah, hawlgalka ugu badan wuxuu hadda yahay 60mA. Taas lidkeeda, 2835 SMD LED waxay si toos ah ula shaqeeyaan 60mA. Loogu talagalay IR LED oo leh 2835 SMD LED, ilaa iyo inta uu chip-ku xamili karo hadda, kiis-dhismeedka LED-ka ee SMD wuxuu qaadan doonaa hadda shaqeynaya sababtoo ah waxaa jira weel kuleyl ah oo hoosta ku yaal oo loogu talagalay kulaylka loo diro. 970nm LED-kan, shaqada ugu badan ee hadda jirta waa 100mA iyo 2835 SMD LED kiis ayaa gabi ahaanba laga helay ~

Tilmaamaha LED-ka ee SMD:

Cabirka: 2.8*3.5*0.7mm;

Dhererka hirarka: 970nm LED (± 10nm);

Nooca muraayadaha: epoxy cad;

Isku halaynta sare iyo isdhexgalka shucaaca sare;

Qiyaasta Korontada:

* Sii wad xajinta hadda: Waajibka 1% iyo ballaca garaaca = 10us.

* Xakamaynta iibinta: Xakamaynta iibinta waa in lagu dhammeeyaa 3 ilbiriqsi at 260 ℃

*Xoojinta iftiinka waxaa lagu qiyaasaa ZWL600.

*λD waxay ka soo dheegtay jaantuska CIE chromaticity shaxanka waxayna ka dhigan tahay hal hirarka dhererka kaas oo qeexaya midabka qalabka.

Wax ka qabashada taxaddarrada:

Isbarbar dhig kumbuyuutar ee Epoxy oo adag oo jajaban, silicone waa mid jilicsan oo rogrogmi kara dabeecaddiisa si weyn u yareeyaan walaaca fekerka, waxay aad ugu nugul tahay waxyeelada awood farsamo. Natiijo ahaan, taxaddar maaliyadeed oo gaar ah ayaa u baahan in la ilaaliyo inta lagu gudajiro kulanka iyadoo la adeegsanayo silicone-ka wax soo saarka leh. Ka gaabinta inaad u hogaansanaato waxay horseedi kartaa waxyeelo iyo guuldarro dhicis ah

1. Wax ka qabashada qaybta dusha sare ee dusha sare adoo adeegsanaya qalab xoog ama qalab ku habboon.

2, si toos ah ha u taaban ama ha u isticmaalin dusha sare ee silikoonka dusha sare. Waxay dhaawici kartaa wareegga gudaha.

3, Ha u xirneyn PCB-ga la soo aruuriyay oo ay ku jiraan dhulalka foorarka ah. Saameyntu waxay xoqsan kartaa muraayadda silikoonka ama waxyeelada u geysan karto wareegga gudaha.

4, 4-MARKA TAARIIKH TILMAAMAHA EE SMD Pagep Board waa inuusan ka badneyn cabirka loo yaqaan 'hoggaamiyihii horseeday inuu ka hortago daadashada hawada;

4-BA Waxyaabaha la sheegi karo waxaa lagu soo jeedinayaa caarada bisadda si looga fogaado acything ama waxyeelada dusha sare ee salka ku haya inta lagu gudajiro.

Cabidhiska qaybta waa in si sax ah loogu habeeyaa mashiinka soo qaadista iyo mashiinka si loo hubiyo qaadista saxda ah kana fogow waxyeelada inta wax soo saarku ka soo baxo;

4-D Sida silsilada silikone waa loo gartaa gaaska, qaar ka mid ah walxaha wasakhaysan sida H2s ayaa laga yaabaa inay ceyriyaan qalin qalin oo ah hoggaamiye horseed. Daryeel gaar ah waa in la qaataa haddii hoggaamiye la mid ah silsiladda silicone-ka ay tahay in loo isticmaalo agagaarka walxahaas oo kale.

5, Fadlan ka dib u sii wad sii wadida soo-gaadhista jawiga qoyaan oo ka fogee sheyga ka fog wareejinta ugu badan ee ku-meel-gaarka ah ee heerkulka ambiamt.

6, wax soo saarka ee xirmada asalka ah ee shaabadaysan ayaa lagula talinayaa in lagu soo ururiyo 24 saacadood gudahood laga bilaabo furitaanka.
