Waht o SMD LED BT Substrate:

SMD LED BT Substrate e faʻasino I LE PCB o loʻo gaosia ma BT Mea ma faʻaaoga i oloa SMD LED. le PCB masani , BT Mea e faʻaaogaina i MD LED BT Substrate, o le tele lava na gaosia e Mistubishi Gas Chemical Co., Inc. BT Meafaitino faia o B (Bismaleimide) ma T (Triazine) resin ei ai le lelei o maualuga TG (255 ~ 330 ° C), vevela tetee (160 ~ 230 ° C), susu tetee, maualalo dielectric tumau (DK) ma maualalo dissipation vaega (Df). SMD LED o se fou luga faʻaputuga semiconductor malamalama-emitting masini, ma se tamai faataʻapeʻapeina tulimanu e tele, malamalama laugatasia, maualuga faatuatuaina, malamalama lanu e aofia ai lanu papaʻe, e lautele faaaogaina i le tele o eletise oloa. Laupapa PCB o se tasi o le sili gaosi oloa SMD TAITAIINA mea.

 Eseesega b va SMD ma COB TAITAIINA

SMD e faʻasino i le faaupuga "Surface Mounted Device" LEDs, o LED ia e pito sili ona fefaʻasoaaʻi i le maketi. O le LED chip e faʻavasega faʻavavau i se lolomi laupapa matagaluega (PCB), ma e sili ona lauiloa ona o lona agavaʻa. o ia PCB ua fausia i luga o se sikuea-foliga, mafolafola mea, o le mea lena e masani ona tatou vaʻaia o SMD. Afai e te vaʻavaʻai atu i totonu SMD LED vavalalata, oe mafai ona vaʻaia se tamaʻi uliuli itu taumatau i le ogatotonu o le SMD; o le malamala TAITAIINA lena. E mafai ona e mauaina i moli malamalama ma moli uila ma e oʻo lava i moli faʻasilasilaga i luga o lau telefoni feaveaʻi.

O se tasi o mea fou na faia i totonu o le LED alamanuia o le COB poʻo le "Chip on Board" tekonolosi o se sitepu i luma mo le sili atu le lelei faʻaaogaina o le malosi. Tutusa ma SMD, COB chips foi e tele diodes i luga o le tutusa luga. Ae o le 'eseʻesega i le va o le LED light COB ma le SMD o le COB LEDs e tele atu diodes.

Lelei o SMD TAITAIINA

1) O le SMD e sili atu ona fetuʻunaʻi, ma o le faʻaalia o ana chips ua filifili e tusa ai ma le lolomiina laupapa laupapa faʻatulagaina, ma e mafai ona suia e faʻafetaui eseese inisinia fofo.

2) SMD malamalama mafuaʻaga o loʻo i ai se sili atu malamalama pupula oʻo i le 120 & Phi; 160 tikeri, laititi lapoa ma mama mamafa o oloa eletise, maualuga potopoto density ma le tele ma le mamafa o le ufiufi vaega e na o le 1/10 o lena masani plug-i vaega.

3) E maualuga lona faʻatuatuaina ma malosi aneti-gatete gafatia.

4) Low solder soʻoga faʻaletonu fua ma faʻaleleia le gaosiga lelei.
