Tūtohu hua

Ko te Waht te SMD LED BT Taapiri:

Ko te SMD LED BT Substrate e pa ana ki TE PCB e hangaia ana me nga Rauemi BT ka whakamahia ki nga hua SMD LED. He rereke , ka whakamahia nga Mea BT i te MD LED BT Substrate, he hua na Mistubishi Gas Chemical Co., Inc. Ko nga Rauemi BT i hangaia o B (Bismaleimide) me te T (Triazine) te painga he teitei te teitei o te TG (255 ~ 330 ° C), te aukati i te wera (160 ~ 230 ° C), te aukati i te hoatutanga, te waatea dielectric iti (DK) me te marara iti tauwehe (Df). Ko te SMD LED he papa hou he taputapu semiconductor-emitting light light, me te kokonga iti o te marara he nui, he maarama, he pono nui, he tae tae tae atu ki nga tae ma, ka whakamahia whānuitia i roto i nga momo taonga hiko. Ko te poari PCB tetahi o nga taonga hangarau SMD LED nui.

Te rereketanga b i waenga i te SMD me te COB LED

SMD e pa ana ki te kupu "Mata Whakauru Pūrere" LED, koinei te LED tino nui i te maakete. Ko te maramara LED ka honoa ki te papa ara iahiko (PCB), a he mea rongonui na te kaha ki te mahi. ko ia PCB kei te hanga i runga i te hanga tapawhā, mea papatahi, koina ta matau e kiia nei he SMD. Mena ka tiro atu koe ki te SMD LED, ka kite koe i tetahi ira pango iti i te waenganui tonu o te SMD; ko te maramara LED. Ka kitea e koe i roto i nga topuku rama me nga rama rama me nga rama whakamarama i runga i to waea pukoro.

Ko tetahi o nga whanaketanga hou o te umanga LED ko te COB, ko te hangarau "Chip on Board" ranei he hikoi whakamua kia kaha ai te whakamahi o te kaha. He rite ki te SMD, ko nga maramara COB he maha ano nga diode i runga i te mata kotahi. Engari ko te rereketanga i waenga i te COB maama me te SMD ko nga COB LED he maha ake nga diode.

Nga painga o te SMD LED

1) He ngawari ake te SMD, a ko te whakaaturanga o ona maramara ka whakatauhia kia rite ki te whakatakotoranga o te poari ara iahiko, ana ka taea te whakarereke kia tutuki ai nga whakataunga hangarau rereke

2) Ko te maarama SMD he nui ake te kokonga o te whakamarama tae atu ki te 120 & Phi; 160 nga nekehanga, te rahi me te taumaha ngawari o nga hua hiko, te kaha o te huihuinga nui me te rahi me te taumaha o nga waahanga taupoki ko te 1/10 noa iho o nga waahanga whakauru-noa.

3) He tiketike te pono me te kaha anti-wiri kaha.

4) He iti te reanga o te reanga o te koha me te whakapiki i te whaihuatanga
