1206 LED SMD Blue Zener Diode Chitetezo cha LED

1206 SMD LED Mtundu wabuluu ndi Zener Diode

Awa ndi ma LED a Blue SMD omwe amapaka paketi ya 1206 SMD LED. Zomwe zimapangitsa kukhala mini ya buluu ya SMD LED.

Nthawi zambiri pamakhala kachipangizo kamodzi mkati mwa buluu la LED. Koma mu 1206BC-ZR, chonde onani pachithunzichi motere, pali tchipisi tina mkati mwa phukusi. Imodzi ndi yoyera komanso yolumikizidwa ndi waya wagolide awiri, womwe ndi buluu ya LED yabuluu. Ndi gwero lowala la SMD LED. Mbali inayi, pali chipini chakuda chakuda, chomwe ndi Zener Diode.

Kodi diode ya Zener ndi chiyani, chifukwa chiyani padzakhala diode ya zener ndipo imagwirira ntchito chiyani?

Choyamba, zener diode ndi mtundu wapadera wa diode wopangidwa kuti ulole molondola pano kuyenda "chammbuyo" pakakhala mphamvu yamagetsi yotsika, yotchedwa zenner voltage, ikafika. Pazinthu zina, ma LED atha kuwonongeka ndi magetsi kapena magetsi. Pofuna kuteteza LED, zidzakhala bwino tikamawonjezera diode ya zener ku dera lamkati. Ndiye diode ya zener ikhoza kuteteza ku LED kuchokera pamagetsi othamanga ndi malo amodzi.

Zachidziwikire, osati 1206 SMD iyi ya LED, ngati mukufuna chitetezo china cha SMD LED kapena nyali ya LED. Monga 0603 SMD LED, 2835 SMD LED 5050 SMD LED ect. Zonse zilipo.

Kukula kwa 1206 SMD LED:

* Kukula uku kumapezekanso pama LED angapo, monga RGB LED, Amber LED kapena LED ect ina *

Magawo Amagetsi:

* Chitani msonkhano wapano: Ntchito 1% ndi Pulse width = 10us.

* Msonkhano wa Soldering: Msonkhano wa Soldering uyenera kumalizidwa ndi 3 secongds pa 260 ℃

* Mphamvu yowala imayesedwa ndi ZWL600.

* λD imachokera ku chithunzi cha CIE chromaticity ndipo imayimira kutalika kwake komwe kumatanthauzira mtundu wa chipangizocho.

Mankhwala Mwatsatanetsatane wa 1206 SMD LED ndi Zener Diode:

Pakapita patsogolo pakupanga kwa LED, chilichonse ndichofunikira kwambiri pakukula kwa SMD LED yathu.

Waya wangwiro wagolide amatha kutsimikizira kuti LED imakhala ndi magwiridwe antchito kwambiri ikakhala pansi pano. Khola la LED lokhazikika limatha kupangitsa kuti ma LED atuluke mofananamo. Epoxy yapamwamba kwambiri imatha kuwonetsa chip cha LED mkati mwabwino ndipo diode ya Zener imatha kuteteza ma LED pamagetsi apamwamba komanso osasunthika;

Ntchito yayikulu ya Blue 450nm LED, 460nm LED ndi 470nm LED:

Njira Yopangira ya SMD LED:

ZOSUNGIRA PA NKHANI

Yerekezerani ndi epoxy encapsulant yolimba komanso yopepuka, silicone ndiyofewa komanso yosinthasintha Althouth mawonekedwe ake amachepetsa kwambiri kupsinjika kwamafuta, kumatha kuwonongeka ndimphamvu yamagetsi. Zotsatira zake, kusamala kwapadera kuyenera kuwonedwa pamsonkhano pogwiritsa ntchito zinthu za Silicone zomwe zidakulungidwa. Kulephera kutsatira izi kumatha kubweretsa kuwonongeka komanso kulephera msanga kwa zomwe akutsogolera

1. Gwiritsani chinthucho m'mbali mwa mbali pogwiritsa ntchito forceps kapena zida zoyenera.

2, Musakhudze mwachindunji kapena kusamalira mandala a silicone. Zingawononge mayendedwe amkati.

3, Musati okwana pamodzi anasonkhana PCBS munali LEDs poyera. Zovuta zimatha kukanda mandala a silicone kapena kuwononga mayendedwe amkati.

4, 4-A Mkati wamkati mwa kamphindi kakang'ono ka SMD sayenera kupitirira kukula kwa LED popewa kutuluka kwa mpweya;

Zolemba 4-BA zimalangizidwa kuti nsonga ya nozzle ipewe kugwirana kapena kuwononga mawonekedwe a LED panthawi yonyamula.

4-C The gawo la chigawocho liyenera kukonzedwa molondola mu makina osankhika ndi malo kuti atsimikizire kutenga bwino ndikupewa kuwonongeka pakupanga;

4-D Monga silicone encapsulation imatha kupezeka m'mipweya, zinthu zina zowononga monga H2S zitha kuwononga siliva plationg wa leadframe. Chisamaliro chapadera chiyenera kutengedwa ngati LED yokhala ndi silicone encapsulation iyenera kugwiritsidwa ntchito pafupi ndi zinthu ngati izi.

5, Chonde aviod mupitilize kuwonetsetsa malo omwe amadzetsa chinyezi ndikusunga malonda ake kuti asadzabwerenso kusintha kwa kutentha kozungulira.

6, Zogulitsa zomwe zidasindikizidwa koyambirira zimalimbikitsidwa kuti zisonkhanitsidwe pasanathe maola 24 kutsegulidwa.
