Buluug ah 480nm ayaa horseeday saliidaha 3014 dhinaca dib u soo celinta

Waa maxay buluug buluug loo isticmaalay?

LED-ga buluugga ah wuxuu noqon karaa buluug smd smd iyo god buluug ah oo loo yaqaan '' 3015pbc48d2l12 waa 480NM oo ay hogaaminayaan xirmadaas oo leh nooca SMD LED. Sababta oo ah waxaa jira laba nooc oo ah dharka gacmaha ee dhinaca hoose iyo hoose. LED-gani waa loo soo bandhigi karaa sida aragtida kore ee loo yaqaan 'LED' iyo aragtida dhinaca. Xaaladdan oo kale, buluuggan buluuga ah ayaa si weyn loogu talagalay mashruuca iftiinka iftiinka, oo hogaamiya mashruuca xayeysiinta. Laba nooc oo cadow ah ayaa kaa caawin doona SMD-kan oo si sahlan u sahlan oo ku habboon mashruuc kala duwan. Iyada oo leh nalka buluugga ah ee quruxda badan, maxaad ka samaynaysaa aragtida buluugga ah ee dhinaca buluugga ah?

3014 cabirka caadiga ah ee xaraashka ah:

Cayayaanka korantada:

* Jidhka garaaca hubka hadda ah: Waajibaadka 1% iyo ballaca garaaca wadnaha = 10us.

* Khariirifka iibinta: Dhaqanka iibinta waa in lagu dhammeeyaa 3 secongds 260 ℃

* Xoogga xoogga badan waxaa lagu cabiray zwl600.

* λD waxaa laga soo qaatay jaantus cheematity Cheagritity oo matalaysa hal-geedka hal goynta ee qeexaya midabka aaladda.

Soosaarka SMD wuxuu horseeday 3014 dhinaca koritaanka:

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.
