Waht waa SMD LED BT Substrate:

Smd LED BT substrate waxaa loola jeedaa PCB THE la-macmalay la BT Qalabka iyo codsatay in ay smd LED products.Different ka PCB caadiga ah , BT Qalabka waxaa laga codsadaa in MD LED BT substrate, taas oo inta badan waa wax soo saarka by Mistubishi Gas Chemical Co., Inc.The Qalabka BT ee ka samaysan B (Bismaleimide) iyo cusbada T (Triazine) waxay leeyihiin faa'iidooyinka TG sare (255 ~ 330 ° C), iska caabbinta kuleylka (160 ~ 230 ° C), u adkaysiga qoyaanka, joogteynta koronto yar (DK) iyo faafitaanka hooseeya isir (Df). SMD LED waa qalab dusha sare ku shaqeeya oo dusha sare, oo leh xagal yar oo firidhsan waa weyn yahay, isku mid ahaanta iftiinka, isku halaynta sare, midabada iftiinka oo ay ku jiraan midabada cad, waxaa si weyn loogu isticmaalaa noocyo kala duwan oo elektaroonik ah. Guddiga PCB waa mid ka mid ah wax soo saarka waaweyn ee wax SMD LED.

 Farqiga u dhexeeya SMD iyo COB LED

SMD waxaa loola jeedaa erayga "Surface Mounted Device" LEDs, kuwaas oo ah laydhadhka ugu wadaaga suuqa. Qalabka LED-ka ayaa weligiis lagu dhajiyaa guddiga wareegga daabacan (PCB), waana mid si gaar ah caan u ah sababtoo ah kala duwanaanshaheeda. isaga PCB wuxuu ku dhisanyahay shay fidsan oo qaab-afar-geesle ah, kaas oo ah waxa aan inta badan u aragno SMD. Haddii aad u fiirsato SMD LED si dhow, waxaad ka arki kartaa dhibic yar oo madow oo ku taal bartamaha SMD; taasi waa jajab LED. Waxaad ka heli kartaa laambadaha nalka iyo nalalka fiilooyinka iyo xitaa nalka ogeysiiska ee taleefankaaga gacanta.

Mid ka mid ah horumarkii ugu dambeeyay ee warshadaha LED-ka ayaa ah teknolojiyadda COB ama "Chip on Board" oo ah tallaabo horay loogu qaaday isticmaalka tamarta waxtarka badan. Si la mid ah SMD, Chips-yada loo yaqaan 'COB chips' sidoo kale waxay leeyihiin dioodyo badan oo isla dusha sare ah. Laakiin farqiga u dhexeeya nalka LED-ka COB iyo SMD ayaa ah in COB LEDs ay leeyihiin dyoodyo badan.

Faa'iidooyinka SMD LED

1) SMD waa mid aad u jilicsan, iyo soo bandhigida jajabkeeda waxaa lagu go'aamiyaa iyadoo loo eegayo qaabka guddiga wareega ee daabacan, waana la beddeli karaa si loo daboolo xalalka injineernimada ee kala duwan.

2) Ilaha iftiinka ee SMD wuxuu leeyahay xagal iftiin ballaaran oo gaaraya illaa 120 & Phi; 160 digrii, cabir yar iyo miisaanka fudud ee alaabta elektarooniga ah, cufnaanta isku imaatinka sare iyo cabirka iyo culeyska qeybaha daboolka ayaa kaliya qiyaastii 1/10 ka mid ah kuwa ka mid ah qeybaha caadiga ah ee fiilada.

3) Waxay leedahay kalsooni sare iyo awood ka hortag gariir.

4) Heerka cilladda wadajirka ah ee hooseeya iyo hagaajinta wax soo saarka wax soo saarka.
